Android：如何忽略或禁用 savedInstanceState？

Question

I want to ignore or disable savedInstanceState so that the state of current activity won't save when I go to the next activity.

public void onCreate(Bundle savedInstanceState){
    super.onCreate(savedInstanceState);

Answer 1

Just this:

public void onCreate(Bundle savedInstanceState){
    super.onCreate(null);

Answer 2

Or this:

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

Answer 3

Write this line in your activity xml file:

    android:saveEnabled="false"

Answer 4

Just override onRestoreInstanceState without calling the super version

@Override
    protected void onRestoreInstanceState(Bundle outState) {
        //Just leave it empty
    }
