Question

我将我的应用设置为全屏显示，但是当我创建并显示片段对话框时，它将退出全屏显示

我尝试两种方法，但对我没有用，请检查代码1和代码2

代码1：加 adding <item name="android:windowFullscreen">true</item> 到我的style.xml 代码2：在片段对话框中覆盖onShow

    @Override
    public void show(FragmentManager manager, String tag)
    {
        getDialog().getWindow().setFlags(WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE, WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE);
        super.show(manager, tag);
        int uiOptions = View.SYSTEM_UI_FLAG_FULLSCREEN;
        getDialog().getWindow().getDecorView().setSystemUiVisibility(uiOptions);
        getDialog().getWindow().clearFlags(WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE);
    }

什么都没发生，我的应用再次从全屏退出

Answer 1

好的，我有自己的答案这段代码使问题得以解决：

getDialog().getWindow().setFlags(WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE, WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE);
getDialog().getWindow().getDecorView().setSystemUiVisibility(getActivity().getWindow().getDecorView().getSystemUiVisibility());

getDialog().setOnShowListener(new DialogInterface.OnShowListener() {
    @Override
    public void onShow(DialogInterface dialog) {
        //Clear the not focusable flag from the window
        getDialog().getWindow().clearFlags(WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE);

        //Update the WindowManager with the new attributes (no nicer way I know of to do this)..
        WindowManager wm = (WindowManager) getActivity().getSystemService(Context.WINDOW_SERVICE);
        wm.updateViewLayout(getDialog().getWindow().getDecorView(), getDialog().getWindow().getAttributes());
    }
});

Answer 2

尝试

@Override
    public void show(FragmentManager manager, String tag)
    {
        getDialog().getWindow().setFlags(WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE, WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE);
        super.show(manager, tag);
        int uiOptions = View.SYSTEM_UI_FLAG_FULLSCREEN;
        getDialog().getWindow().getDecorView().setSystemUiVisibility(uiOptions);
        getDialog().getWindow().clearFlags(WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE);

        // add these two line
        getDialog().requestWindowFeature(1);
        getDialog().getWindow().setBackgroundDrawable(new ColorDrawable(0));
    }

Answer 3

尝试一下：

@Override
public void onResume() {
    // Get existing layout params for the window
    ViewGroup.LayoutParams params = getDialog().getWindow().getAttributes();
    // Assign window properties to fill the parent
    params.width = WindowManager.LayoutParams.MATCH_PARENT;
    params.height = WindowManager.LayoutParams.WRAP_CONTENT;
    getDialog().getWindow().setAttributes((android.view.WindowManager.LayoutParams) params);
    // Call super onResume after sizing
    super.onResume()

}
