تأكد من استدعاء الدالة putString لحفظ القيمة في Bundle
هل استخدمة الثابت NAME_KEY؟
public class MainActivity extends Activity {
public TextView nameTextView;
public final static String NAME_KEY=“Ahmad”;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
nameTextView = (TextView) findViewById(R.id.textView);
}
@Override
protected void onSaveInstanceState(Bundle outState) {
putString(NAME_KEY);
super.onSaveInstanceState(outState);
}
@Override
protected void onRestoreInstanceState(Bundle savedInstanceState) {
super.onRestoreInstanceState(savedInstanceState);
}
}
