Unzuverlässiges Ergebnis für die Überprüfung der eingehenden Nummer in Kontakt

Question

Ich verwende Code hier Check Incoming number is stored in Contacts list or not android für die Prüfung, ob eingehende Nummer vorhanden ist oder nicht in Kontakten. Dieser Code gibt immer kein korrektes Ergebnis.

Ist auf diesem oder einem anderen besseren Weg eine Korrektur erforderlich?

Code:

String res = null; 
try { 
    ContentResolver resolver = context.getContentResolver(); 
    Uri uri = Uri.withAppendedPath(ContactsContract.PhoneLookup.CONTENT_FILTER_URI, Uri.encode(phoneNumber)); 
    String a = uri.getLastPathSegment(); 
    Cursor c = resolver.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, new String[]{ContactsContract.CommonDataKinds.Phone.NUMBER}, ContactsContract.CommonDataKinds.Phone._ID + "=?", new String[]{a}, null); 

    if (c != null) { // cursor not null means number is found contactsTable 
     if (c.getCount() > 0) { 
     if (c.moveToFirst()) { // so now find the contact Name 
      res = c.getString(c.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)); 
      //res = c.getString(c.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME)); 
     } 
     c.close(); 
     } 
    } 
} catch (Exception ex) { 
    ex.printStackTrace(); 
} 
return res;

Versuchen Sie den Code unten seiner einfachen & für mich arbeiten.

public class TestActivity extends Activity { 

private static final int REQUEST_CONTACT_NUMBER = 8512885487; 

/** Pops the "select phone number" window */ 
public void onBrowseForNumbersButtonClicked(View view) { 
    Intent contactPickerIntent = new Intent(Intent.ACTION_PICK, Phone.CONTENT_URI); 
    startActivityForResult(contactPickerIntent, REQUEST_CONTACT_NUMBER); 
} 

protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
if (resultCode == RESULT_OK) { 
    if(data != null && requestCode == REQUEST_CONTACT_NUMBER) { 
    Uri uriOfPhoneNumberRecord = data.getData(); 
    String idOfPhoneRecord = uriOfPhoneNumberRecord.getLastPathSegment(); 
    Cursor cursor = getContentResolver().query(Phone.CONTENT_URI, new String[]{Phone.NUMBER}, Phone._ID + "=?", new String[]{idOfPhoneRecord}, null); 
    if(cursor != null) { 
    if(cursor.getCount() > 0) { 
     cursor.moveToFirst(); 
     String formattedPhoneNumber = cursor.getString(cursor.getColumnIndex(Phone.NUMBER)); 
     Log.d("TestActivity", String.format("The selected phone number is: %s", formattedPhoneNumber)); 
    } 
    cursor.close(); 
    } 
    } 
else { 
    Log.w("TestActivity", "WARNING: Corrupted request response"); 
} 
} 
else if (resultCode == RESULT_CANCELED) { 
    Log.i("TestActivity", "Popup canceled by user."); 
} 
else { 
    Log.w("TestActivity", "WARNING: Unknown resultCode"); 
} 
} 
}
