Display default contact photo in listView when no photo assigned?

I have a listview which displays the Starred Contacts with photo and name. I've managed so far to display the photos of the contacts which have one. The problem is that when a contact hasn't a photo only the name displayed and not the default contact(from drawables).
Here is the related code:
Code:
Uri queryUri = ContactsContract.Contacts.CONTENT_URI;
String[] projection = new String[] {
ContactsContract.Contacts._ID,
ContactsContract.Contacts.LOOKUP_KEY,
ContactsContract.Contacts.PHOTO_THUMBNAIL_URI,
ContactsContract.Contacts.DISPLAY_NAME,
ContactsContract.Contacts.STARRED};
String selection =ContactsContract.Contacts.STARRED + "='1'";
Cursor cursor = managedQuery(queryUri, projection, selection,null,null);
long id= cursor.getColumnIndex(ContactsContract.Contacts._ID);
Bitmap bitmap = loadContactPhoto(getContentResolver(), id);
if(bitmap!=null){
favIcon.setImageBitmap(bitmap);
}
else{
}
String[] from = {ContactsContract.Contacts.PHOTO_THUMBNAIL_URI, ContactsContract.Contacts.DISPLAY_NAME};
int to[] = new int[]{
R.id.ivDefContact,
R.id.tvContactName
};
ListAdapter adapter = new SimpleCursorAdapter(
this,
R.layout.favs_list_item,
cursor,
from,
to,
CursorAdapter.FLAG_REGISTER_CONTENT_OBSERVER);
final ListView listStarred = (ListView) findViewById(R.id.lvFavs);
listStarred.setAdapter(adapter);
}
public static Bitmap loadContactPhoto(ContentResolver cr, long id) {
Uri uri = ContentUris.withAppendedId(ContactsContract.Contacts.CONTENT_URI, id);
InputStream input = ContactsContract.Contacts.openContactPhotoInputStream(cr, uri);
if (input == null) {
return null;
}
return BitmapFactory.decodeStream(input);
}
How can I achive this?
EDIT:
The app run fine, but I also get these errors on logcat:
I/System.out: resolveUri failed on bad bitmap uri:
E/BitmapFactory: Unable to decode stream: java.io.FileNotFoundException: /: open failed: EISDIR (Is a directory)

Did you managed to fix this? I have the same problem.

[Q] Parse Bluetooth received string

Hi, I have a newbie question..
I have modified the bluetoothChat example to get serial data from my pc to my phone over bluetooth.
The code uses the following code to keep listening for incoming data:
Code:
public void run() {
Log.i(TAG, "BEGIN mConnectedThread");
byte[] buffer = new byte[1024];
int bytes = 0;
// byte x = 0;
// Keep listening to the InputStream while connected
while (true) {
try {
// Read from the InputStream
bytes = mmInStream.read(buffer);
// Send the obtained bytes to the UI Activity
mHandler.obtainMessage(BluetoothChat.MESSAGE_READ, bytes, -1, buffer)
.sendToTarget();
} catch (IOException e) {
Log.e(TAG, "disconnected", e);
connectionLost();
// Start the service over to restart listening mode
BluetoothChatService.this.start();
break;
}
}
}
And in the MainActivity the following code when data is received:
Code:
case MESSAGE_READ:
byte [] readBuf;
//readBuf = (byte[]) msg.obj;
readBuf = (byte[]) msg.obj;
String readMessage = new String(readBuf, 0, msg.arg1); // create string from bytes array
messageString = messageString + readMessage;
if (messageString.length()<10){
TextView text = (TextView) findViewById(R.id.textView1); // Display output
text.setText("<10....");
break;
}
sb.append(readMessage); // append string
int endOfLineIndex = sb.indexOf("#"); // determine the end-of-line
if (endOfLineIndex > 0) { // if end-of-line,
String sbprint = sb.substring(0, endOfLineIndex); // extract string
sb.delete(0, sb.length()); // and clear
TextView text = (TextView) findViewById(R.id.textView1); // Display output
text.setText(sbprint);
mConversationArrayAdapter.add(mConnectedDeviceName+": " + readMessage);
}
break;
As shown i have added a endOfLineIndex loop to find the end of the received string and show the received string in a textfield. The problem with my code is when sending a string like "0123456789#" the shown text in the textView1 is mostly not the send string.. I get strings like 0123,4560123456789, etc.. Somehow there is still data in the buffer i quess.
Is there a way to clear or ignore the received data and only parse the wanted string form the buffer? If this is possible i can add a start identifier to the string..
The main goal is too parse a string like: #150,000,001,000,0.0,-0.1,40.3,144.0,001,OKE where each value is a variable which needed to be placed in a textview.
Thanks for any suggestions!
Kind regards,
Bas

This one "0123456789#" should return "0123456789". Does it?
You invoke substring().
Quote from the docs:
The substring begins at the specified beginIndex and extends to the character at index endIndex - 1.

(http://docs.oracle.com/javase/1.4.2/docs/api/java/lang/String.html#substring(int, int))
That means that the last character (the #) is missed out.

Thanks Nikwen,
I do miss out the end off string character #. The problem is i get different strings out of the buffer... If i send 0123456789# with a one second interval i get different results.. sometimes i get the string like expected which is 0123456789. but most of the time i get results like 0123, 456789,12,1,etc etc. it looks like the buffer is not cleared or something

A question about list

Hi.
I am building an app that has a list. All of the clicks on list items result in one activity, like XActivity. XActivity contains a text view. I want that when I click on ListItem1 the text view shows a string forexample string1, then onClickListItem2 it shows string2, onListItemClicX it shows stringX. If it's confusing let me know.
How can I handle it ?
Thanks in advance.

I'm assuming you're using an ArrayAdapter - it would be helpful if you posted some code.
You have to setup an OnItemClickListener for your ListView. In the OnItemClick method, you will have to get the data from the adapter using the position that was clicked. Then create an intent to ActivityX and pass the clicked data.
Code:
[B]ArrayAdapter adapter = new ArrayAdapter();[/B]
listView.setClickable(true);
//Setup the on item click listener for the listview
listView.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
//Create an intent pointing to XActivity
Intent intent = new Intent(this, XActivity.class);
//Add the clicked string as an extra
intent.putExtra("KEY_CLICKEDSTRING", adapter.getItem(position - 1));
//Start the activity
this.startActivity(intent);
}
});
In ActivityX, simply retrieve the data and set it in the textview:
Code:
@Override
public void onCreate(Bundle savedInstanceState) {
... Activity setup code
TextView textView = findViewById(R.id.yourtextview);
//Get the intent data
String strClicked = getIntent().getStringExtra("KEY_CLICKEDSTRING");
textView.setText(strClicked);
}

Thank you.
But I don't know what value does the "int position" give me ? Forexample does it give the value of "1" or .... ?
I want to know that in order to know which item was clicked and now what to do .
Can anybody help me ?
Thanks in advance.

Like previously mentioned. Post your code and we can help you out better.

not complex, First I make a new ArrayAdapter<string> add adapt it to my listView. Up to know no problem. But in the continue :
// usual codes to answer a click onItemClick(AdapterView<?> av, View v, int position, long id) {
//create a intent as Alkonic said
//My problem }
...
@My problem I want to use a set of codes and understand which item was clicked. I have 41 items and my idea is this :
// getting the text of the clicked item String title = ((TextView)v).getText().toString();
If (title=getString(R.string.theTextIHadAddedToArrayAdapterForItem1)) {
// so item 1 was clicked
//Change the text of thesecond TextView in the second activity ( wich I wrote intent for)
// rewrite the if order 41 times for 41 items
...
But this doesn't work. Can anybody help me ?
@Alconic :
I don't understand the method you wrote for retrieving intent data ( I mean
//Get the intent data String strClicked = getIntent().getStringExtra("KEY_CLICKEDSTRING");
) because the "Key_CLICKEDSTRING" is always constant and one thing. How can I cange it for 41 items ?
Thank you guys anyway.

You should post your onItemClick routine. But for going at it blind on our side this is what I would do:
Code:
public void onItemClick(AdapterView<?> av, View v, int pos, long id) {
//Get text from a textview that is on your listview
TextView textView2 = (TextView) v.findViewById(R.id.myTextView);
String txtMytext = textView2.getText().toString();
//Create an intent pointing to XActivity
Intent intent = new Intent(this, XActivity.class);
//Add the clicked string as an extra
intent.putExtra("KEY_CLICKEDSTRING", txtMytext);
//Start the activity
this.startActivity(intent);
}
Without your code, I don't understand what you are comparing with the if statement you posted. Use this along with @Alkonic 's code should get you in the right direction. If it doesn't, we need more code to help better.

Handling Clicks:
The int position refers to the position of the item that was clicked in the arrayadapter.
Instead of this:
Code:
String title = ((TextView)v).getText().toString();
you can use
Code:
String title = adapter.getItem(position);
That code will take the clicked position and get the clicked string from the adapter.
Intent Data
When you send data with an intent, it has two parts: the Name and Value.
The following code sets the name to a constant "Key_CLICKEDSTRING" and the Value is variable, depending on what was clicked.
Code:
intent.putExtra("KEY_CLICKEDSTRING", adapter.getItem(position));
When you want to access the VALUE, you have to provide the constant name:
Code:
String strClicked = getIntent().getStringExtra("KEY_CLICKEDSTRING");
Hope that helped!

Java is too complex for begginer lovers

I love Android. I want to learn to develop apps. I keep reading tutorials. I got dissapointed and read about HTML frameworks (phonegap, etc). I came back to Android Native Java. I want to learn from the roots. However, some things discourages me....
All this part of the code is just for making a request to the Openweather API and get the json data (plus a little debugging stuff); which in Python or similar languages you only have to care about
- importing the library that handles http requests
- make the request in one function and save it into a json object
Code:
HttpURLConnection urlConnection = null;
BufferedReader reader = null;
// Will contain the raw JSON response as a string.
String forecastJsonStr = null;
String format = "json";
String units = "metric";
int numDays = 7;

.appendQueryParameter(QUERY_PARAM, params[0])
.appendQueryParameter(FORMAT_PARAM, format)
.appendQueryParameter(UNITS_PARAM, units)
.appendQueryParameter(DAYS_PARAM, Integer.toString(numDays))
.build();
URL url = new URL(builtUri.toString());
Log.v(LOG_TAG, "Built URI " + builtUri.toString());
// Create the request to OpenWeatherMap, and open the connection
urlConnection = (HttpURLConnection) url.openConnection();
urlConnection.setRequestMethod("GET");
urlConnection.connect();
// Read the input stream into a String
InputStream inputStream = urlConnection.getInputStream();

// Nothing to do.

I mean, I know this code can be reduced, but I'm angry about the way it works. Everything needs to be passed to another object! And even rembember all those castings! Castings everywhere!
- The builded URI to the URL.
- The URL to the HttpConection variable.
- Once you connect, save that into the InputStream.
- Make a StringBuffer because we are going to send line by line everything.
- Then create the reader = new BufferedReader(new InputStreamReader(inputStream)).
- Append the lines to the buffer and return if it's ok.
- Else catch all the errors and be sure to close all the connections.
Damn Java !
Forgive me. You'll hate me.
Java is readable, that's the truth... but don't tell me that it is easy for a normal person.
Am I the only one?

If you are a beginner and will straight move to these classes. You will obviously find Java difficult. But Java is very easy if you move step by step from start

And that library also does the same thing inside. Only difference is, your work is already done by author of the library.

Java is definitely a very verbose language but it's also widely used and so you will find many libraries that do tasks like grab JSON data from a service that have already been implemented for you

I don't think you're the only one. It's easy to get scared away by the many too verbose examples available, the key is to look at what you're trying to achieve and then break it up into those parts.
Your code listing is (I think) an attempt to show all steps to get the forecast data, but if that would have been broken up into smaller steps I don't think you'd look at it as quite as bad.
You would then have methods like
Code:
URL getForecastUrl(String parameter);
Code:
BufferedReader getUrl(URL url) { }
Code:
String readAll(BufferedReader reader) {}
Each of which would have had something like 6-7 lines of simple, cohesive code.
I understand your point, but in this particular scenario I think you're the victim of a poorly structured code sample rather than a too verbose language.

If you think the default implementation is too complicated, here are also many java libraries which will make your life easier.

setActualDefaultRingtoneUri(,RingtoneManager.TYPE_ RING,) not work on s7 edge

Hi guys, could anyone help me with this?
I am trying to develop an application that could automatic change the ringtone for incoming calls, because all the existed applications which has this feature could not works well on my Galaxy S7 Edge,
but then I found out is't not that easy to change ringtone on Galaxy S7 Edge.
I am tried with these code:
File sdFile = new File("/mnt/storage/26D9-150C/test.mp3");
ContentValues values = new ContentValues();
values.put(MediaStore.MediaColumns.DATA, sdFile.getAbsolutePath());
values.put(MediaStore.MediaColumns.TITLE, sdFile.getName());
values.put(MediaStore.MediaColumns.MIME_TYPE, "audio/*");
values.put(MediaStore.Audio.Media.IS_RINGTONE, true);
values.put(MediaStore.Audio.Media.IS_NOTIFICATION, false);
values.put(MediaStore.Audio.Media.IS_ALARM, false);
values.put(MediaStore.Audio.Media.IS_MUSIC, false);
Uri uri = MediaStore.Audio.Media.getContentUriForPath(sdFile.getAbsolutePath());
getContentResolver().delete(uri ,null ,null);//if not delete, maybe it will cause some error.
Uri newUri = this.getContentResolver().insert(uri, values);
RingtoneManager.setActualDefaultRingtoneUri(this, RingtoneManager.TYPE_RINGTONE, newUri);
These code works fine on other devices, also on the Galaxy S7 Edge, you can see the new ringtone with code below, the ringtone changed into the target file, but when you received a phone call it's not the the ringtone that I set ! It's still the old ringtone before I run that code above. What's the problem ????? And I checked the ringtone from "Setting-Sound and vibrate-ringtone-incoming ringtone" it's never changed!!!
And I have granted the WRITE_SETTINGS permission already.
private Uri getSystemDefaultRingtoneUri() {
return RingtoneManager.getActualDefaultRingtoneUri(this, RingtoneManager.TYPE_RINGTONE);//RingtoneManager.TYPE_ALL
}
private String getRealPath(Uri fileUrl) {
String fileName = null;
Uri filePathUri = fileUrl;
if (fileUrl != null) {
if (fileUrl.getScheme().toString().compareTo("content") == 0) {
Cursor cursor = mContext.getContentResolver().query(fileUrl, null, null, null, null);
if (cursor != null && cursor.moveToFirst()) {
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
fileName = cursor.getString(column_index);
if (!fileName.startsWith("/mnt")) {
fileName = "/mnt" + fileName;
}
cursor.close();
}
} else if (fileUrl.getScheme().compareTo("file") == 0) {
fileName = filePathUri.toString().replace("file://", "");
if (!fileName.startsWith("/mnt")) {
fileName += "/mnt";
}
}
}
return fileName;
}
Then I searched everywhere, and find out that it seems samsung changed the system, the TYPE_RINGTONE will not effect on samsung anymore, is it true ? How could fix this problem ?
Why samsung change it like this ? It's really ****ty for developers!

You need the
<uses-permission android:name="android.permission.WRITE_SETTINGS"/>
Permission. Only grantable for System apps.

Thanks for your reply.
I have this permission in my manifest.xml already.
It seems samsung ringtong not use the standard database...

As I said, your app must be a system app (or a privileged app). Or else, adding this manifest to a normal app will not function at all and is useless.

Actually I think it's not the metter about the permission, the permission has been authorized, and the ringtone really changed into my ringtone on my device,
use these code you can see the default ringtone has changed after set.
private Uri getSystemDefaultRingtoneUri() {
return RingtoneManager.getActualDefaultRingtoneUri(this, RingtoneManager.TYPE_RINGTONE);//RingtoneManager.TYPE_ALL
}
Also use a different application to check the default ringtone, it's changed into the one that I choosen.
But in fact the the ring of incoming call from the speaker never changed.
So I think samsung use a different ringtone database or whatever.
Oh, and all kinds of random ringtong tools not work on S7edge.
I will try to figure it out when I rooted my s7edge.
And before this, I found some information about samsung ring of alarm, so I think the call maybe the same reason, http://bbs.anzhuo.cn/thread-938419-1-1.html
anyway, thanks for reply.

And here is the way for android 6.0.1 to ask the WRITE_SETTINGS permission
private boolean checkMyPermission(boolean isSecondTimeCheck) {
String dialogTitle = "need WRITE_SETTINGS permission";
if (isSecondTimeCheck) dialogTitle = "you deny the permission";
String btnTitle = "ok", if (isSecondTimeCheck) btnTitle = "try again";
if (Build.VERSION.SDK_INT >= 23) {
if (!Settings.System.canWrite(this)) {
new AlertDialog.Builder(mContext).setMessage(dialogTit le).setPositiveButton(btnTitle, new DialogInterface.OnClickListener() {
 @override
public void onClick(DialogInterface dialog, int which) {
Intent intent = new Intent(Settings.ACTION_MANAGE_WRITE_SETTINGS, Uri.parse("package:" + getPackageName()));
startActivityForResult(intent, REQUEST_CODE_PERMISSION);
}
}).setNegativeButton("cancel", null).create().show();
return false;
}
return true;
} else {
int hasWriteContactsPermission = ContextCompat.checkSelfPermission(mContext, Manifest.permission.WRITE_SETTINGS);
if (hasWriteContactsPermission != PackageManager.PERMISSION_GRANTED) {
new AlertDialog.Builder(mContext).setMessage(dialogTit le).setPositiveButton(btnTitle, new DialogInterface.OnClickListener() {
 @override
public void onClick(DialogInterface dialog, int which) {
Intent intent = new Intent(Settings.ACTION_MANAGE_WRITE_SETTINGS, Uri.parse("package:" + getPackageName()));
startActivityForResult(intent, REQUEST_CODE_PERMISSION);
}
}).setNegativeButton("cancel", null).create().show();
return false;
} else {
return true;
}
}
}

The permission has NOT been authorized. Please try to wrap your head around this. Your code is really messy.
https://github.com/android/platform_frameworks_base/blob/master/core/res/AndroidManifest.xml#L1597
Line 1600 states that you must have built the system through same firmware signature, "preinstalled" (priv-app), appop and pre-23 API
1595 states that it has a protection level of signature meaning that if the app isn't signed with the same signature as the ROM it won't be authorized to use that permission.
You can also try "pm grant YOUR_APP_NAME android.permission.WRITE_SETTINGS" in adb shell - and you will get an error saying it isn't a grantable permission.
Finally, if your app is a downloadable app from Play Store, this is the only caveat. Unless you request root to priv-app, THIS PERMISSION ISN'T GRANTED.
Java:
private boolean checkWriteSettingsPermissions() {
String permission = "android.permission.WRITE_SETTINGS";
int res = getContext().checkCallingOrSelfPermission(permission);
return (res == PackageManager.PERMISSION_GRANTED);
}
This is simple code that allows you to check whether your app is granted the permission.

Thank you for your patient.
1. I tried your code, and I was wrong about the permission, it says PERMISSION_DENIED. but I think this is not the problem for this question.
2. Did you tried my code ? The way that I asked for "WRITE_SETTINGS" is really work for ringtone, altho
Java:
private boolean checkWriteSettingsPermissions() {
String permission = "android.permission.WRITE_SETTINGS";
int res = getContext().checkCallingOrSelfPermission(permission);
return (res == PackageManager.PERMISSION_GRANTED);
}
said "PERMISSION_DENIED" , but it's really changed the ringtone ! If you not believe this, please try by yourself, and you can see from the setting - ring and vibrate - ringtone , you can see the result.
3. After several times try, I figure it out now... both way(manual and auto set by code "setMyRingtone()") of set the ringtone will work on the phone if have the permission of "Settings.System.canWrite(this)", but only work for the Ringtone of SIM 1, not work for SIM2. you can see the result form the setting page(only the ringtone for sim1 will change). if the ringtone still play the default ring of system, the problem probably is the metter of URI .
4. Before I post this thread, both way won't change the result of ringtone from the setting page of the phone, but as I said , you can see the result form another third part application.(this problem most probably is that I only use one SIM card at that time, did I put it into sim2? I don't know, already forget... but now if I put it into sim2 the ringtone form the setting page of the phone never change, but from the log of the code you can see the result is correct actually.)
5. Now the problem change into "How to create a standard URI and how to change the ringtone for SIM2". I will try to work on it.
6. Sorry for my pool English, and sorry for the "messy" code, I will improve it.
Anyway , thank you. you r the only one who helped me... Wish u luck.

I had the ringtone added on my MediaProvider but not set as the current one, I believe AOSP and TW deving is different.
When I mentioned "messy" I meant just copying and pasting the code into the forum, use
Code:
tags next time so it formats perfectly! :good::highfive:
