android - IllegalArgumentException : Window type can not be changed after the window is added

Question

我已经尝试了 here 的建议, 建议 here , 建议 here ，我已经在我的基本 Activity 中注释掉了 onAttachedToWindow() 。我有两个继承自此类 BaseActivity 的 Activity 。一个跑，一个不跑。有什么区别？我的目标 SDK 是 19；将其更改为 12 没有区别。这是我对 BaseActivity 的 onCreate:

    @Override
    protected void onCreate(Bundle savedInstanceState) {
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
    this.getWindow().setType(WindowManager.LayoutParams.TYPE_KEYGUARD);
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    super.onAttachedToWindow();
    super.onCreate(savedInstanceState);

    ....
    }

当导航到第二个 Activity 时，单步执行代码，它会通过 onCreate()、onResume()，然后崩溃。

可能是什么问题？

EDIT:如果我更改为目标 API 12 并将所有更改从 onCreate 放入 onAttachedToWindow，我可以得到这个异常离开，但我希望目标 SDK 为 19。

我的新 onCreate():

@Override
protected void onCreate(Bundle savedInstanceState) {

    requestWindowFeature(Window.FEATURE_NO_TITLE);
    super.onCreate(savedInstanceState);
...
}

我的新 onAttachedToWindow():

@Override
public void onAttachedToWindow() {
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
    this.getWindow().setType(WindowManager.LayoutParams.TYPE_KEYGUARD);
    super.onAttachedToWindow();
}

这仅适用于目标 API 12。

回答 Min target must be less than 14 when WindowManager.LayoutParams.TYPE_KEYGUARD used

Answer 1

尝试将其用于窗口:

requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                     WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.activity_adjectives);
