Question

当我点击一个按钮时，我必须将我的活动设置为全屏。在互联网上搜索我找到了这样做的代码。

container.setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_STABLE
                                | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
                                | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                                | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION // hide nav bar
                                | View.SYSTEM_UI_FLAG_FULLSCREEN // hide status bar
                                | View.SYSTEM_UI_FLAG_IMMERSIVE);

但是我做错了什么，因为状态栏和导航栏消失了，我的活动仍然保持相同的高度。

</RelativeLayout>

有人可以帮助我吗？感谢

Answer 1

可能有更好的方法，但我使用的最简单的方法是，

    // Fullscreen
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);

我把它放在Activity类中。

Answer 2

 @Override
public void onWindowFocusChanged(boolean hasFocus) {
    super.onWindowFocusChanged(hasFocus);
    if (hasFocus) {
        getWindow().getDecorView().setSystemUiVisibility(5894);

    }
}

我希望它能完成工作

Answer 3

 getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
