如何在Android 6.0中隐藏导航栏? [英] How to hide the navigation bar in Android 6.0?

问题描述

我有以下代码:

getWindow().getDecorView().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
            | View.SYSTEM_UI_FLAG_FULLSCREEN
            | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY);

此代码在Android Lollipop上运行良好，将导航栏隐藏在粘性沉浸式模式下.但是现在，当我在装有Android 6.0的手机上对其进行测试时，导航栏消失了，而原来保留导航栏的黑色矩形却挡住了屏幕的一部分.

This code worked fine for Android Lollipop, hiding the navigation bar in sticky immersive mode. But now, when I test it on my phone with Android 6.0, the navigation bar goes away while a black rectangle where the navigation bar used to be remains, blocking a portion of the screen.

推荐答案

回想一下我的问题，我想添加我正在使用的解决方案，自那以后我一直没有失败，我不记得是否我在其他地方看到了它，或者我亲自来到了它，但我很高兴它能起作用.

Looking back on my question, I'd like to add the solution I'm using now which hasn't failed me since, I don't remember if I saw it somewhere else or came to it myself but I'm glad it works.

public static void activiateFullscreen(Activity activity){
    View decorView = activity.getWindow().getDecorView();
    int uiOptions = View.SYSTEM_UI_FLAG_HIDE_NAVIGATION;
    if (Build.VERSION.SDK_INT >= 17) {
        uiOptions ^= View.SYSTEM_UI_FLAG_LAYOUT_STABLE
                | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
                | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                | View.SYSTEM_UI_FLAG_FULLSCREEN
                |View.SYSTEM_UI_FLAG_LOW_PROFILE;
    }
    if (Build.VERSION.SDK_INT >= 19) {
        uiOptions ^= View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY;
    }
    decorView.setSystemUiVisibility(uiOptions);
}
