hello friends i'm new here and sorry for my question i'm big beginner and an autolearner.
i'm doing an app for android basicaly mock up. and i created a projectwith drawer menu and menu item are stocked in string not in array.
when i run it if i click on an item the number of row of the item appear in the mainactivity.xml what i realy want is to start a new activity here is my code i hope i can get help here,
Code:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mNavigationDrawerFragment = (NavigationDrawerFragment)
getFragmentManager().findFragmentById(R.id.navigation_drawer);
mTitle = getTitle();
// Set up the drawer.
mNavigationDrawerFragment.setUp(
R.id.navigation_drawer,
(DrawerLayout) findViewById(R.id.drawer_layout));
}
@Override
public void onNavigationDrawerItemSelected(int position) {
// update the main content by replacing fragments
FragmentManager fragmentManager = getFragmentManager();
fragmentManager.beginTransaction()
.replace(R.id.container, PlaceholderFragment.newInstance(position + 1))
.commit();
}
public void onSectionAttached(int number) {
switch (number) {
case 1:
mTitle = getString(R.string.title_section1);
break;
case 2:
mTitle = getString(R.string.title_section2);
break;
case 3:
mTitle = getString(R.string.title_section3);
break;

Modify your onNavigationDrawerItemSelected method as follows
PHP:
@Override
public void onNavigationDrawerItemSelected(int position) {
switch (position) {
case 0:
//For loading a fragment
Fragment yourfragment = new Yourfragment();
// update the main content by replacing fragments
FragmentManager fragmentManager = getSupportFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager
,beginTransaction();
fragmentTransaction.replace(R.id.container, yourfragment );
onSectionAttached(0);
fragmentTransaction.commit();
break;
case 1:
//To start a new activity
Intent intent = new Intent(this,destination.class);
startActivity(intent);
break;
case 2:
//To do something else like a dialog or a toast
Toast.maketext(context,"Sample Toast",Tosat.LENGTH_LONG).show();
break;
}
}
hello friend thank you very much for your response i edited my code like this
Code:
@Override
public void onNavigationDrawerItemSelected(int position) {
switch (position) {
case 0:
//For loading a fragment
FragmentVue1 FragmentVue1 = new FragmentVue1();
// update the main content by replacing fragments
FragmentManager fragmentManager = getSupportFragmentManager();
FragmentManager fragmentTransaction = fragmentManager;
beginTransaction();
fragmentTransaction.replace(R.id.container, FragmentVue1 );
onSectionAttached(0);
fragmentTransaction.commit();
break;
case 1:
//To start a new activity
Intent intent = new Intent(this,FragmentVue1.class);
startActivity.intent();
break;
FragmentVue1 is the name of my activity 1 and the activity load the layout, the code i posted up is little edited than than that you gave me on up reply, because eclipse stress it that suggested me some code to change for exemple
HTML:
Fragment Frgment1 = new FragmentVue1();
raplace in this code is still empty and eclipse ask me to Add cast method receiver
HTML:
fragmentTransaction.replace(R.id.container, FragmentVue1 );
and in this code too fro commit
HTML:
fragmentTransaction.commit();
for this code
HTML:
startActivity.intent();
eclipse is asking me to crete local variable startActivity, create field starActivity,create parameter startActivity create class, and constant .
i'm sorry if i bring to difficult place i really need it to change layout(fragment) to start it just for show a mock up

I guess using
"startActivity(intent);"
instead of
"startActivity.intent();" will please eclipse
and not to mention will solve the issue
I bet u didn google that

you don't need to use any code present in case 0 if you are not loading a fragment. I just wrote that to make sure you know the difference between starting an activity and a fragment.
If you just want too start an activity just use what is inside case 1.
and as @sak-venom1997 said it should be startActivity(intent) instead of startActivity.intent(). My bad (i am a confused person )
so suppose FragmentVue1 is your activity's name and you want to open it on clicking nth item of navigation drawer use
PHP:
case n:
Intent intent = new Intent(this,FragmentVue1.class);
startActivity(intent);
break;

thank you very much for yours reply both are usefully @sak-venom1997
yes FragmentVue1 is my activity it load a layout the reality is i know difference between Activity and Layout but no the both with Fragment.
now it working but the MainActivity is empty when i start the app and i find a warning in code below case 1 break i copied the warning in message in the below code in the line of warning
PHP:
private void onSectionAttached(int i) {
// TODO Auto-generated method stub

private void beginTransaction() { // WARNING: The method beginTransaction() from the type MainActivity is never used locally

If i understand you the right way, you are extending Fragment. In this case you are overriding some methods, but dont modify them. How did you get the code? Via the eclipse menu saying "override/implement methods"? Or did you copy the code from somewhere? If you really need to keep the code, i think you have to call super in the method.

You don't need to add these lines, they are for opening a fragment. I just provided them to help you know how to open a fragment from navigation drawer.

Moderators... It says I am breaking the rules by asking a question and to ask in the Q&A... But the title of this is "Coding Discussion, Q&A, and Educational Resources" I am not breaking the rules intentionally, I just don't know where else to put this. This is a Coding Question, not a General Question that I would think would get buried and or lost in the General Q&A forum. Please move if you feel I am incorrect.
Hello All, I was hoping someone could help me.
I am trying to create an app that will hide pictures. I want to be able to Pick my App from the Share (Send To) menu from the Users Gallery and have it copy the file to a Directory I have created on my SDCard and then ultimately delete the file from the current location.
Here is what I have so far, but when I pick my app from the Share menu, it crashes the Gallery app. So... I can't even see any errors in my LogCat to even try and troubleshoot my issue.
Can someone point me to a working example of how to do this (I have searched the internet until I am blue in the face) or... I hate to say it... Fix my Code?
Any Help would be appreciated... Thanks!!

What's the gallery log output?
Btw, you're not breaking the rules. This is the right forum for Java Q&A.

Do you view the logs on your computer?
There should be an error message in the logs.

Which Logs?? As I said before. LogCat does not give any errors.
I have to record the touch event of any android (.apk) application. For that I have created the .jar(Library) file which is responsible to record touch event when user press any control. This .jar will be injected with any .apk file.
For achieve the above things I have follow the below step.
1)I have created application with only one button name App.apk.
2)Also Create the another library project called Test.jar
3)Give the dependency of Test.jar to App.apk.
Now I want send same event to test.jar. I have write below code in App.apk activity
@override
public void onResume()
{
super.onResume();
Test.Event.MyHook(this);
}
@override
public void onPause()
{
super.onPause();
Test.Event.MyUnHook(this);
}
@override
public boolean dispatchKeyEvent(android.view.KeyEvent event)
{
Test.Event.MyEvent(event);
return super.dispatchKeyEvent(event);
}
Can u suggest the way to get button click event from App.apk to Test.jar ?
Thanks

Seems rather fishy why you'd have to do that, but let's roll with it...^^
TLDR: in pure java, using standard APIs or even reflection or root, you can't.
You could use the android-event-injector project (which is a C++/JNI library) : https://code.google.com/p/android-event-injector/
It provides methods to listen to all input events, something like that (this will send all the results to logcat):
PHP:
public void StartEventMonitor() {
m_bMonitorOn = true;
Thread b = new Thread(new Runnable() {
public void run() {
while (m_bMonitorOn) {
for (InputDevice idev:events.m_Devs) {
// Open more devices to see their messages
if (idev.getOpen() && (0 == idev.getPollingEvent())) {
final String line = idev.getName()+
":" + idev.getSuccessfulPollingType()+
" " + idev.getSuccessfulPollingCode() +
" " + idev.getSuccessfulPollingValue();
Log.d(LT, "Event:"+line);
}
}
}
}
});
b.start();
}
You can read more here: http://www.pocketmagic.net/2013/01/programmatically-injecting-events-on-android-part-2/
However, you might also be able to do that using the Xposed framework and finding a hook into the actual framework class for dispatchKeyEvent if it's the event you want to intercept.
I've never with Xposed so I can't really help you with the implementation, though, but it might be something to look into.
i want to save a layout (relative layout), when i run the app everything is working fine, but i am unable to find saved file/s in the internal storage of the phone. Any help would be appreciated as i am new and unable to sort out what is going wrong . here is my code
Code:
public void saveMe(View v) {
// get prompts.xml view
LayoutInflater li = LayoutInflater.from(this);
View promptsView = li.inflate(R.layout.prompt, null);
AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(
context);
// set prompt.xml to alertdialog builder
alertDialogBuilder.setView(promptsView);
final EditText userInput = (EditText) promptsView
.findViewById(R.id.editTextDialog);
// set dialog message
alertDialogBuilder.setCancelable(false);
alertDialogBuilder.setPositiveButton("OK",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
final String fileName = userInput.getText().toString();
final View view1=findViewById(R.id.relativeLayout); // The view that you want to save as an image
Bitmap bitmap = Bitmap.createBitmap(view1.getWidth(), view1.getHeight(), Bitmap.Config.ARGB_8888);
Canvas c = new Canvas(bitmap);
view1.draw(c);
if(fileName.length() == 0)
Toast.makeText(EidCardFinal.this,"Please Enter File Name",Toast.LENGTH_SHORT).show();
else{
File file = new File(context.getFilesDir(), fileName);
if (file.exists())
Toast.makeText(EidCardFinal.this,"File Already Exists",Toast.LENGTH_SHORT).show();
else{
try{
FileOutputStream out = new FileOutputStream(file);
bitmap.compress(CompressFormat.PNG, 100, out);
Toast.makeText(EidCardFinal.this,"File Saved",Toast.LENGTH_SHORT).show();
out.close();
}
catch (Exception e) {
e.printStackTrace();
}
}
}
}
});
alertDialogBuilder.setNegativeButton("Cancel",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
dialog.cancel();
}
});
// create alert dialog
AlertDialog alertDialog = alertDialogBuilder.create();
// show it
alertDialog.show();
}
Try adding a line:
out.flush();
just before calling close() on the FileOutputStream. I think this will get the save code to work, and it's worth trying.

Could you please be more specific about your errors? Error output from eclipse in case of compile error or if it did compile but has runtime errors then post the logcat output for example. This would help
Edit::
Well for the first i wouldnt distribute the onclick listeners so much, instead let your activity implement OnClickListener so you have one onClick method for all, that is far more ordered. Then put a switch inside it: switch (v.getId()) { //v is the clicked button
case R.id.btnLogin:
//login button code here
case R.id. .... :
......
}
Then it is more structured

Wich IDE are you using ?
If you can't run it it means that it's a compilation failure, probably a syntax error. Most of Java IDE tells you where is the error even before you run it.

Well it tells you which line it is, take a look at it (probably where you close your second on click listener in the second activity). Remember that each bracket, curly or round has to get closed before the statement can be finished with a ; . Another thing I just noticed, you now set the onClickListener for btnRegister twice in the second activity, you can't do that. Probably the code of the first one should be executed after the code in the other click listener.

Well read the whole thing, at the line in bold it tells you that you have a NullPointerException at line 44 of the Login activity. You should read nikwen's guide on logcats and debugging .

If you want to check that some data is actually present then just write it to the log. Eg.
Log.V("Testing", someString);
If it is working then someString will be printed after the "Testing" tag. If its not then you should check your logcat to find out why not.
This is what I have:

When I import "uri" for my on activity results at the end of my code I get a bunch of errors for everything I'm doing with parse. I been searching and trying different image picker tutorials and always end up with same results. I've checked out parse.com but only see info on saving images from the drawable folder. If I can get the image picker to work I'm pretty sure I can figure out how to save it to parse.com.
