Im having issues with my App. What i'd like to do is when my Button is pressed to open my Phone Contatcs and display them to my TextViews. I have issues when i perform the Button Press i think.
At least LogCat is saying me some Error with my Button but i can't figure out whats wrong.
In my Manifestfile i've already set the permissions for reading and writing contacts. I have a ContactView.java where the Code happens and i've already created the view with Button and 2 textView's.
Maybe someone can help me or at least tell me what im doing wrong.
In my view i said: android:onClick="pickContact"
import android.content.Intent;
import android.database.Cursor;
import android.net.Uri;
import android.os.Bundle;
import android.provider.ContactsContract;
import android.support.v7.app.AppCompatActivity;
import android.util.Log;
import android.view.View;
import android.widget.TextView;
public class ContactView extends AppCompatActivity {
private static final int RESULT_PICK_CONTACT = 85500;
private TextView textView1;
private TextView textView2;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_contact_view);
textView1 = (TextView) findViewById(R.id.TxtName);
textView2 = (TextView) findViewById(R.id.TxtNumber);
}
public void pickContact(View v)
{
Intent contactPickerIntent = new Intent(Intent.ACTION_PICK,
ContactsContract.CommonDataKinds.Phone.CONTENT_URI);
startActivityForResult(contactPickerIntent, RESULT_PICK_CONTACT);
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// check whether the result is ok
if (resultCode == RESULT_OK) {
// Check for the request code, we might be usign multiple startActivityForReslut
switch (requestCode) {
case RESULT_PICK_CONTACT:
contactPicked(data);
break;
}
} else {
Log.e("ContactView", "Failed to pick contact");
}
}
/**
* Query the Uri and read contact details. Handle the picked contact data.
* @param data
*/
private void contactPicked(Intent data) {
Cursor cursor = null;
try {
String phoneNo = null ;
String name = null;
// getData() method will have the Content Uri of the selected contact
Uri uri = data.getData();
//Query the content uri
cursor = getContentResolver().query(uri, null, null, null, null);
cursor.moveToFirst();
// column index of the phone number
int phoneIndex =cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);
// column index of the contact name
int nameIndex =cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME);
phoneNo = cursor.getString(phoneIndex);
name = cursor.getString(nameIndex);
// Set the value to the textviews
textView1.setText(name);
textView2.setText(phoneNo);
} catch (Exception e) {
e.printStackTrace();
}
}
This is what LogCat says after i press my addcontacts Button while debugging:

private static final int RESULT_PICK_CONTACT = 85500;
Please try to change it to something lower like:
private static final int RESULT_PICK_CONTACT = 85;
