Help writing something with setOnItemClickListener

In my Android app, I have a sound that I want to play when a certain selection has been made from a spinner, but I want it to play the when the user actually makes the proper selection (or just after). My problem is that although the sound does play when they make the correct selection, as long as that selection stays chosen, it also plays every time the app starts up, when it should ONLY play at the time it's chosen. I think I need to change my setOnItemSelectedListener to setOnItemClickListener, but I'm not sure how (still pretty new to java). Can any generous soul out there show me how to change this up (assuming that's how to best solve this problem)?
Here is the code I have now:
Code:
fitnessSpinner = (Spinner) findViewById(R.id.fitness_spinner);
ArrayAdapter adapter4 = ArrayAdapter.createFromResource(
this, R.array.fitness_array, android.R.layout.simple_spinner_item);
adapter4.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
fitnessSpinner.setAdapter(adapter4);
fitnessSpinner.setOnItemSelectedListener(new OnItemSelectedListener()
{
@Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long i) {
Log.d("test", "p: " + position + " " + i);
if(position == 0) {
//First Entry
MediaPlayer mp = MediaPlayer.create(mContext, R.raw.bowchica);
mp.start();
} if(position == 4) {
MediaPlayer mp = MediaPlayer.create(mContext, R.raw.debbie2);
mp.start();
}
}
@Override
public void onNothingSelected(AdapterView<?> arg0) {
}
});

I haven't try the below code but you can try it on your own and tell us.
In onCreate() declare MediaPlayer mp;
In every if statement that you use for check insert this code:
Code:
if(mp!=null){mp.release();}
int resid = R.raw.yoursound;
mp = MediaPlayer.create(this, resid);
After that override the methods onPause() and onResume() and insert this:
if(mp!=null){mp.release();}
If it is still playing a sound when you start your app, then you should check your code again if you have set as default option any of your selection options.

I would LOVE to try this out...Unfortunately, I'm way too dumb at this point point ot figure out exactly where those code snippets would go inside of what I already have.
Does anyone have a couple of minutes to show me where it would go?

Below is a sample code. Since i don't know your code I give you a snippet that you should adjust it to your code.
Code:
public class SampleSound extends Activity{
private Spinner fitnessSpinner;
private MediaPlayer mp;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);//here goes your layout
setViews();//here you will set all your views(spinners buttons textviews etc..)
setAdapters();//set your adapters here
setListeners();//
}
private void setListeners() {
fitnessSpinner.setOnItemSelectedListener(new OnItemSelectedListener(){
@Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long i) {
Log.d("test", "p: " + position + " " + i);
if(position == 0) {
//First Entry
if(mp!=null){mp.release();}
int resid = R.raw.bowchica;
mp = MediaPlayer.create(this, resid);
mp.start();
} if(position == 4) {
if(mp!=null){mp.release();}
int resid = R.raw.debbie2;
mp = MediaPlayer.create(this, resid);
mp.start();
}
}
@Override
public void onNothingSelected(AdapterView<?> arg0) {
}
});
}
private void setAdapters() {
ArrayAdapter adapter4 = ArrayAdapter.createFromResource(this, R.array.fitness_array, android.R.layout.simple_spinner_item);
adapter4.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
fitnessSpinner.setAdapter(adapter4);
}
private void setViews() {
fitnessSpinner = (Spinner) findViewById(R.id.fitness_spinner);
}
public void onResume(){
super.onResume();
if(mp!=null){mp.release();}
}
public void onPause(){
super.onPause();
if(mp!=null){mp.release();}
}
}

I really appreciate the help. I put the code in my routine, but it still plays the sound every time the activity is loaded (as long as the selection in the spinner is correct). It should only play the sound when the correct selection is made.
Any other ideas?

I am sure that your Spinner is set to some value (since you have values to display). Because your Spinner points to a selection (doesn't matter if you have selected or it is selected by default) your sound plays (even when you start the app).
A way to stop the sound playing at start is to declare and an other Item like you did with the previous 4 and set it as default selection of your Spinner.
To sum up:
1.You have to append in R.array.fitness_array an Item (like you did with the previous Items) and give it a name.
2.At the end of method setAdapters() insert this:
Code:
fitnessSpiner.setSelection(5);// or whatever is your selection number
Now it should work but you should know that this is not a good practice and you should try make a ListView or something else.

I'd be happy to change this out to a listview, or whatever would work. I just have to give my user a choice of 4 or 5 items, from which they can choose only one. Something like a drop down box, but in Android, I thought my only option was a spinner. But whatever I use, I have to be able to play a sound when certain items are chosen, but ONLY when those items are chosen, NOT whenever the activity is called up.
Any specific ideas of what I might change to?

What if I had another control like a textview or an edittext (with it's visibility property set to false) that I programatically populated with the users selection (when it's the selection that I want) and then have an OnItemClcickListener set to play the sound?
Could that work?

I will answer from the last to the top of your questions.
1.You can do whatever you want with android. You want TextViews and EditTexts with complex and nested Layouts you can do it. Write services that will communicate with your contacts through a content provider? You can do it.
Write, read and test code. Only this way you will actually learn.
2.Read developer.android.com. Read the android tutorials from there and specifically the Notepad example. You will learn a lot.
A good resource with small examples for ListViews is this.
3.Have you tried the changes I told you from the last post? Did it worked?
Since you just started with android and programming you must first be happy if you have the expected result and then read more to make your code better

Your suggested changes (fitnessSpiner.setSelection(5);// or whatever is your selection number) would stop the sound from playing, but defeat the apps purpose. Every time this activity is loaded, the spinners hit preferences to load the previously stored data. So if I force the spinner to a different selection to NOT play sound when the activity loads, then I would be displaying the wrong data for the user.

Yes you are right. So it is better to make a ListActivity. Read developer.android.com and the link i gave you before. You will be ok with this!

You're using "setOnItemSelectedListener", which sounds like when the app starts, its getting "selected" again.
Have you tried using "setOnItemClickListener" instead?
fitnessSpinner.setOnItemClickListener(new AdapterView.OnItemClickListener () {
public void onItemClicked() {}
};

onClickListener doesn't work for the spinner...I wish it did.
I REALLY need the drop down functionality of teh spinner, so I guess I'm going to try and figure out a way to have an invisible edittext that I set to the spinner selection and then use onClickListener or onChange...

[Q] Repeat Button Action

Hello. New here and I hope this post is okay. The "Is this a question?" checkbox says it not the QA forum but it is?
Working on an app that all it's supposed to do is repeat taking a picture every 5 seconds after pressing a button. Now, I've looked at handler, timer, etc but I can't figure out the right way to do it. This is the code currently, and the onCameraClick of course runs when the button on the screen is pressed. I want that button to activate some kind of repeater so the picture gets taken every 5000ms.
Code:
public class CameraImage extends Activity {
public static int cameraID = 0;
public static ImageView image;
[user=439709]@override[/user]
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.cameraimage);
image = (ImageView) findViewById(R.id.imgView);
}
public void onCameraClick(View v)
{
cameraID = 1;
Intent i = new Intent(CameraImage.this, CameraView.class);
startActivityForResult(i, 9999);
}
}
Now, this is something I'd definitely like to use but I'm not sure how to implement this correctly into the code above. Been trying trial and error for past few hours and nothing. Tried out a timer example someone put on another website, 10792454/image-capture-in-android-automatically but not much there.
At the same time however though, I'm not sure if the code should go in the other class with all the functions to run the camera. Any suggestions/tip or help I'd greatly appreciate it.

Try a loop. I'm not sure if you have tried this or if it will work with launching an activity, but it sounds like that is what you want to do. I don't know how you determine when to stop taking pictures but you can use a "for loop" or a "while loop".
example "for loop":
Code:
for (int i; i > someNumber; i++){
//Your code here
}
someNumber would be perhaps the number of pictures you want to take and you can use i to number each picture.
example "while loop":
Code:
Boolean buttonClick = false;
onCreate(){
OnButtonClick(){
OnClick(){
if(buttonClick == true){
buttonClick = false;
}else{
buttonClick = true;
}
onCameraStart(buttonClick);
}
public void onCameraStart(boolean runCamera){
while (runCamera == true){
//Your code here
}
}
This example I showed you how you would be able to start the camera on the first click and stop it when clicked again. The OnButtonClick would be the OnClickListener for your button.
Both these examples may need a little refinement but this should point you in the right direction. Hope this helps. You can put these in threads and pause the thread at the end of the loop for 5 secs so it will wait (I think).

It's simple use a timer and invoke it on first click

[Q] Issues with adding objects to a photo taken by the user

I've been trying to learn to program for Android lately by simply coming up with ideas and implementing them. It started out easy enough with pulling information from an online RSS feed and showing this in a nice environment. But the current idea has me stumped.
I'd like the following to happen:
Take a picture using intent
Entire picture is shown in a new activity
Zoom in on a certain spot
Add predefined items to the picture
Press next which connects the items from left to right
Add some more items
Press next to connect the new items
Zoom out
Save the image
First taking a picture, this wasn't too hard using the camera intent:
Code:
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
fileUri = getOutputMediaFileUri(MEDIA_TYPE_IMAGE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);
I can then extract the absolute path from fileUri with the following line:
Code:
String path = new File(fileUri.getPath()).getAbsolutePath();
This path can be put in a bundle which can be put in an intent which is then used to start the activity that should show the image.
Code:
public class TestActivity extends Activity implements SurfaceHolder.Callback {
private static final String TAG = TestActivity.class.getSimpleName();
private String path = "";
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
SurfaceView view = new SurfaceView(this);
setContentView(view);
Intent intent = getIntent();
Bundle bundle = intent.getExtras();
path = bundle.getString("path");
view.getHolder().addCallback(this);
}
@Override
public void surfaceCreated(SurfaceHolder holder) {
Canvas canvas = holder.lockCanvas();
if (canvas == null) {
Log.d(TAG,"Can't draw because canvas is null");
}
else {
Bitmap bitmap = BitmapFactory.decodeFile(path);
Paint paint = new Paint();
if(bitmap == null) {
Log.d(TAG,"Can't draw because bitmap is null");
}
else {
canvas.drawBitmap(bitmap,0,0,paint);
}
holder.unlockCanvasAndPost(canvas);
}
}
@Override
public void surfaceChanged(SurfaceHolder holder, int frmt, int w, int h) {
}
@Override
public void surfaceDestroyed(SurfaceHolder holder) {
}
}
The first issue here is that it of course doesn't show the entire photo. Not that surprising considering it's larger than the view. Ideally I'd like to zoom out to show the entire photograph. Once I've zoomed one way I'd assume that zooming in on the part that you want should also be possible.
Next is adding the objects. My idea was simply catching any touch events and adding a new object once the finger is released. This way I'd end up with a list of items with each having a draw function which can be called through the surfaceview when it is redrawn.
Connecting these items could simply be done by creating a line object and going through the list of all items and using their locations for the begin and endpoints of the lines
One of the big issues here is that the x and y locations would be relative to the screen, not to the photo. Which would mean that when you zoom back out the entire background would change but the actual items would remain at the same spot and in the same size.
I've been searching and searching for any tutorial or other question about the same issue, but either I've had no luck or I've been using the wrong keywords. And for all I know everything I have up till now could be wrong.
If anyone could give some pointers, or maybe knows a guide or tutorial somewhere or some better keywords I could use for searching I'd really appreciate it.

would you just not need to either control or track the sample/scale if the image so that you know the 1st pixel displayed (top left) and the scale factor, then the eventX/Y can be processed to be relative to what you want ?

[Q]How to change imageview to another with an interval

Hello,
I got a question. I'm trying to develop an app with some traffic light, it is made out of open source images. It is from a learn to develop android apps couse from udemy. I wanted to add something, I thought about a button with an automatic change function and stop function, with an interval to change the lights on and off. Do you guys have any idea how to do that?
Thanks in advance,

I think you can use this :
Code:
new Handler().postDelayed(new Runnable() {
@Override
public void run() {
/* Put below your new function. */
Intent intent = new Intent(SplashActivity.this, MainActivity.class);
startActivity(intent);
finish();
}
}, 5000);
Second parameter is the interval in seconds. (eg: 5 seconds = 5000)

[Tutorial] Learn to create a Matrix Effect

Hello,
I create that thread to present you a tutorial learning you how to create a Matrix Effect, also known as Digital Rain Effect, on Android. The tutorial is also available as a Youtube video :
Create a Matrix Effect on Android
Also know as Digital Rain Effect, the Matrix Effect is a classic effect featured in the Matrix series films. A green code is falling and represents the activity of the virtual reality environment of the Matrix on screen. On Android, Matrix Effect has been implemented in various applications often as a Live Wallpaper. In that tutorial, you are going to learn how to create a simple Matrix Effect.
1. Create a Matrix Effect custom View
First, you need to create a custom view named MatrixEffect :
Code:
package com.ssaurel.digitalraineffect;
import android.content.Context;
import android.graphics.Bitmap;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Paint;
import android.util.AttributeSet;
import android.view.View;
import java.util.Random;
/**
* Created by ssaurel on 22/09/2016.
*/
public class MatrixEffect extends View {
private static final Random RANDOM = new Random();
private int width, height;
private Canvas canvas;
private Bitmap canvasBmp;
private int fontSize = 40;
private int columnSize;
private char[] cars = "+-*/!^'([])#@&?,=$€°|%".toCharArray();
private int[] txtPosByColumn;
private Paint paintTxt, paintBg, paintBgBmp, paintInitBg;
public MatrixEffect(Context context, AttributeSet attrs) {
super(context, attrs);
paintTxt = new Paint();
paintTxt.setStyle(Paint.Style.FILL);
paintTxt.setColor(Color.GREEN);
paintTxt.setTextSize(fontSize);
paintBg = new Paint();
paintBg.setColor(Color.BLACK);
paintBg.setAlpha(5);
paintBg.setStyle(Paint.Style.FILL);
paintBgBmp = new Paint();
paintBgBmp.setColor(Color.BLACK);
paintInitBg = new Paint();
paintInitBg.setColor(Color.BLACK);
paintInitBg.setAlpha(255);
paintInitBg.setStyle(Paint.Style.FILL);
}
@Override
protected void onSizeChanged(int w, int h, int oldw, int oldh) {
super.onSizeChanged(w, h, oldw, oldh);
width = w;
height = h;
canvasBmp = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888);
canvas = new Canvas(canvasBmp);
canvas.drawRect(0, 0, width, height, paintInitBg);
columnSize = width / fontSize;
txtPosByColumn = new int[columnSize + 1];
for (int x = 0; x < columnSize; x++) {
txtPosByColumn[x] = RANDOM.nextInt(height / 2) + 1;
}
}
private void drawText() {
for (int i = 0; i < txtPosByColumn.length; i++) {
canvas.drawText("" + cars[RANDOM.nextInt(cars.length)], i * fontSize, txtPosByColumn[i] * fontSize, paintTxt);
if (txtPosByColumn[i] * fontSize > height && Math.random() > 0.975) {
txtPosByColumn[i] = 0;
}
txtPosByColumn[i]++;
}
}
private void drawCanvas() {
canvas.drawRect(0, 0, width, height, paintBg);
drawText();
}
@Override
protected void onDraw(Canvas canvas) {
super.onDraw(canvas);
canvas.drawBitmap(canvasBmp, 0, 0, paintBgBmp);
drawCanvas();
invalidate();
}
}
First, we define the variables for the Matrix Effect with the size of the code, the size of a column, the position of the bottom text for each column and then the caracters that will be used for the code. Note that you can put the caracters you want here or why not a custom font.
In the constructor, we initialize the paint objects. To get view width and height, we override the onSizeChanged method of the View. We initialize the position of the first caracter for each column. We use a random position between the top of the screen and the middle of the screen.
Then, we define a draw text method used to draw a random caracter for each column at the position indicated by txtPosByColumn variable.
The drawCanvas method is used to draw the background of our view and then the code.
Finally, we override the onDraw method of our custom view to call the drawCanvas method and invalidate the view to force a redraw. With that call, the Matrix Effect could progress from top to bottom in infinite mode. Note that it is not the most optimized way to manage a Matrix Effect, but for a tutorial it's sufficient.
2. Define the MatrixEffect View on the Layout
Now, we can define the MatrixEffect View on the layout of the Main Activity.
Code:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.ssaurel.digitalraineffect.MainActivity">
<com.ssaurel.digitalraineffect.MatrixEffect
android:layout_width="match_parent"
android:layout_height="match_parent" />
</RelativeLayout>
3. Set the layout on the Main Activity
Last step is to set the layout as content view for the Main Activity.
Code:
package com.ssaurel.digitalraineffect;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
}
4. Demo
To enjoy the Matrix Effect, you have just to launch the application on an Android device and you sould see the following effect :
Don't hesitate to give it a try and give me your feedbacks.
Thanks.

I really like this animated wallpaper app.

Thanks for the detailed tutorial, it's always nice to see actually what the code does. :highfive:
In theory, would it be possible to take smali from the app you create and use it to create this effect on the notification screen (for example)?

Seeing the code I’m sure this app drain a lot of battery but it's very nice.

Did you mean put the effect on the lock screen ? I thought it was not possible now to put live wallpaper on lock screen. If it's possible it could be great.

Should be possible to pull the AOSP lockscreen source (or the source from OEM variants that are actually available...) and replace the wallpaper code, right?

Hello! nice tutorial, everything works fine. But I would like to add buttons to change the colors of chars but i'm not able to call the method from the main activity.
I've tried this but giving errors
Code:
MatrixEffect matrixEffect = new MatrixEffect(); // this gives an error : MatrixEffect(Context, AttributSet) in MatrixEffect cannot be applied to ()
final Paint paintTxt = effetMatrix.peindreTxt;
paintTxt.setColor(Color.BLUE);
Is there a way that I can call paintTxt.setColor() to change color?
PS: Im just a noob on programming

If you want to add buttons to change the color of the Matrix Effect, you should work on the layout and add two buttons at the bottom of the screen under the MatrixView. The, you have to change the colors of the Matrix Effect when a user click on one of these buttons.

Already solved. I added 4 buttons for 4 colors and i used switch statement
1st, created a custom text color inside MAtrixEffect
Code:
public void setCustomTextColor(int color){
peindreTxt.setColor(color);
invalidate();
then, in mainactivity :
Code:
public class MainActivity extends AppCompatActivity implements View.OnClickListener {
MatrixEffect matrixEffect;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
matrixEffect = (MatrixEffect) findViewById(R.id.arrPlan);
final Button boutton_blanc = (Button) findViewById(R.id.b_bl);
final Button boutton_bleu = (Button) findViewById(R.id.b_b);
final Button boutton_rouge = (Button) findViewById(R.id.b_r);
final Button boutton_rose = (Button) findViewById(R.id.b_ro);
if (boutton_bleu != null) {
boutton_bleu.setOnClickListener(this);
}
if (boutton_blanc != null) {
boutton_blanc.setOnClickListener(this);
}
if (boutton_rouge != null) {
boutton_rouge.setOnClickListener(this);
}
if (boutton_rose != null) {
boutton_rose.setOnClickListener(this);
}
}
@Override
public void onClick(View v) {
switch(v.getId()){
case R.id.b_bl:
matrixEffect.setCustomTextColor(Color.WHITE);
break;
case R.id.b_b:
matrixEffect.setCustomTextColor(Color.BLUE);
break;
case R.id.b_ro:
matrixEffectsetCustomTextColor(Color.MAGENTA);
break;
case R.id.b_r:
matrixEffect.setCustomTextColor(Color.RED);
break;
case R.id.b_def:
matrixEffect.setCustomTextColor(Color.GREEN);
break;
}
}
}
Now it works fine and i can change color while a button is pressed
