سلام.
من در برنامه ام می خواهم نام کوچک و بزرگ را بصورت جدا از دفتر تلفن بدست بیاورم.
اما وقتی از پروسه PrintContacts استفاده میکنم برنامه با فورس کلوز (خطای زمان اجرا) روبرو میشه. فقط وقتی که از “ContactsContract.CommonDataKinds.StructuredName ” استفاده میکنم.

مشکل چیه؟

با تشکر

    public void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);

    setContentView(R.layout.main);



    Uri allContacts = ContactsContract.Contacts.CONTENT_URI;



    Cursor c;

    if (android.os.Build.VERSION.SDK_INT <11) {

        c = managedQuery(allContacts, null, null, null, null);

    } else {

        CursorLoader cursorLoader = new CursorLoader(this, allContacts, null, null, null, null);

        c = cursorLoader.loadInBackground();

    }



    String[] columns = new String[] {

            ContactsContract.Contacts.DISPLAY_NAME,

            ContactsContract.Contacts._ID

    };



    int[] views = new int[] {R.id.contactName, R.id.contactID};



    SimpleCursorAdapter adapter;



    if(Build.VERSION.SDK_INT <11){

        adapter = new SimpleCursorAdapter(this, R.layout.main, c, columns, views);

    } else {

        adapter = new SimpleCursorAdapter(this, R.layout.main, c, columns, views,

                CursorAdapter.FLAG_REGISTER_CONTENT_OBSERVER);

    }



    this.setListAdapter(adapter);

    PrintContacts(c);

}





private void PrintContacts(Cursor c){

    if(c.moveToFirst()){

        do{

            String contactID = c.getString(c.getColumnIndex(ContactsContract.Cont  acts._ID));

            String contactGivenName = c.getString(c.getColumnIndex(ContactsContract.Comm  onDataKinds.StructuredName.GIVEN_NAME));

            Toast.makeText(this, contactGivenName, Toast.LENGTH_SHORT).show();

        }while(c.moveToNext());

    }

}
