Question

I have a fragment with one main fragment displayed on it. When I rotate the screen, the activity is beeing recreated. What would be the best way to store the info about currently displayed fragment for screen state restore purposes?

Answer 1

You can use the method onSaveInstanceState to store values in a bundle:

@Override
protected void onSaveInstanceState(Bundle outState) {
    super.onSaveInstanceState(outState);

    outState.putString(MY_FIRST_KEY,valueToSave);
}

then you can restore the values in the method onRestoreInstanceState

 @Override
 protected void onRestoreInstanceState(Bundle inState) {
    super.onRestoreInstanceState(inState);

    valueToSave = inState.getString(MY_FIRST_KEY);
 }

You can also set an xml attribute on TextViews and EditText called “freezeText” which saves any text that was set.
