Android:如何忽略或禁用savedInstanceState？

Question

我想忽略或禁用savedInstanceState,以便在进入下一个活动时不会保存当前活动的状态.

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

Answer 1

只是这个:

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

Answer 2

或这个:

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

Answer 3

在活动xml文件中写下这一行:

    android:saveEnabled="false"
