Please tell me how when turning the Activity to save data in the AlertDialog.Builder dialog

There is an Activity in it code

AlertDialog.Builder alert = new AlertDialog.Builder(this); LayoutInflater layoutInflater = getLayoutInflater(); final View v1 = layoutInflater.inflate(R.layout.dialog_edit_car, null); alert.setView(v1); AlertDialog alertDialog = alert.show();

On the R.layout.dialog_edit_car layer are the EditText, RadioButton. Question: how to save their data when the activity is rotated. AlertDialog.Builder did not find the onSaveInstanceState and onRestoreInstanceState methods on AlertDialog.Builder. What is the right thing to do?

Did so

 public class MainActivitySettings extends AppCompatActivity { View viewSettingsDialog = null; //наш алерт диалог @Override protected void onCreate(Bundle savedInstanceState) {...} @Override protected void onRestoreInstanceState(Bundle savedInstanceState) { super.onRestoreInstanceState(savedInstanceState); if(viewSettingsDialog!=null) { ((EditText) viewSettingsDialog.findViewById(R.id.editText_driveMarka)).setText(savedInstanceState.get("key").toString()); } } @Override protected void onSaveInstanceState(Bundle outState) { super.onSaveInstanceState(outState); if(viewSettingsDialog!=null) { outState.putString("key", ((EditText) viewSettingsDialog.findViewById(R.id.editText_driveMarka)).getText().toString()); } } protected void addCar(){ AlertDialog.Builder alert = new AlertDialog.Builder(this); LayoutInflater layoutInflater = getLayoutInflater(); viewSettingsDialog = layoutInflater.inflate(R.layout.dialog_edit_car, null); alert.setView(viewSettingsDialog); final AlertDialog alertDialog = alert.show(); ((Button) viewSettingsDialog.findViewById(R.id.buttonSaveSettings)).setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { alertDialog.cancel(); } }); } }
