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

就是这样：

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

Answer 2

或者这个：

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

Answer 3

在活动xml文件中写下此行：

    android:saveEnabled="false"

Answer 4

只需覆盖onRestoreInstanceState而不调用超级版本

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