Kontakte werden nicht auf meinem Edittext angezeigt

Question

So habe ich versucht, Kontakt zu einem Editiertext hinzuzufügen, ich habe Onclickevent verwendet, um Kontakte aufzurufen und dann, sobald ein Kontakt ausgewählt wurde, sollte es in Edittext geschrieben werden, aber ich bin nicht in der Lage, das zu tun, unter meinem onActivity Ergebnis ist,

@Override 
protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
    if (resultCode == RESULT_OK) { 
     switch (requestCode) { 
      case CONTACT_PICKER_RESULT: 
       Cursor cursor = null; 
       String name = ""; 
       try { 
        Uri result = data.getData(); 
        //writeToFile("uri" +result); 
        String id = result.getLastPathSegment(); 

        // query for name 
        cursor = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, 
          null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID + "=?", new String[] { id }, 
          null); 

        if (cursor != null && cursor.moveToFirst()) 
        { 
         int phoneIdx = cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DATA); 
         int nameIdx = cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME); 
         writeToFile("ifcursor" +phoneIdx+nameIdx); 
         name = cursor.getString(nameIdx); 
        } 



       } catch (Exception e) { 
        //Log.e(DEBUG_TAG, "Failed to get name", e); 
       } finally { 
        if (cursor != null) { 
         cursor.close(); 
        } 
        // phNo = (EditText) findViewById(R.id.phone_number); 
        phNo.setText(name); 
        if (name.length() == 0) { 
         Toast.makeText(getApplicationContext(),"Name not found for contact.",Toast.LENGTH_LONG).show(); 
        } 

       } 

       break; 
     } 

    } else { 
     //Log.w(DEBUG_TAG, "Warning: activity result not ok"); 
    } 
} 

jede mögliche Hilfe würde sehr geschätzt werden, es Stuck auf

„Namen nicht gefunden“ Versuchen sie diesen

@Override 
    protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
     // Check which request it is that we're responding to 
     if (requestCode == PICK_CONTACT_REQUEST) { 
      // Make sure the request was successful 
      if (resultCode == RESULT_OK) { 
       // Get the URI that points to the selected contact 
       Uri contactUri = data.getData(); 
       // We only need the NUMBER column, because there will be only one row in the result 
       String[] projection = {Phone.NUMBER}; 

       // Perform the query on the contact to get the NUMBER column 
       // We don't need a selection or sort order (there's only one result for the given URI) 
       // CAUTION: The query() method should be called from a separate thread to avoid blocking 
       // your app's UI thread. (For simplicity of the sample, this code doesn't do that.) 
       // Consider using CursorLoader to perform the query. 
       Cursor cursor = getContentResolver() 
         .query(contactUri, projection, null, null, null); 
       cursor.moveToFirst(); 

       // Retrieve the phone number from the NUMBER column 
       int column = cursor.getColumnIndex(Phone.DISPLAY_NAME); 
       String number = cursor.getString(column); 
        phNo.setText(number); 


       // Do something with the phone number... 
      } 
     } 
    }

Wenn Sie den Benutzer benötigen, um p ick einen Kontakt mit einer Telefonnummer, sollten Sie die folgende Absicht nennen:

Intent i = new Intent(Intent.ACTION_PICK, Phone.CONTENT_URI); 
startActivityForResult(i, CONTACT_PICKER_RESULT); 

Dann können Sie die Antwort in onActivityResult wie so handhaben:

Uri result = data.getData(); 
// because we asked for a Phone.CONTENT_URI picker, we'll get a uri for a Phone._ID entry 
String id = result.getLastPathSegment(); 
String[] projection = new String[] { Phone.DISPLAY_NAME, Phone.NUMBER }; 
String selection = Phone._ID + "=" + id; 
Cursor cursor = getContentResolver().query(Phone.CONTENT_URI, projection, selection,null, null); 

if (cursor != null && cursor.moveToFirst()) { 
    String name = cursor.getString(0); 
    String number = cursor.getString(1); 
    Log.d("MyActivity", "got name=" + name + ", phone=" + number); 
} 
if (cursor != null) { 
    cursor.close(); 
}
