【Android】隐藏底部虚拟按键

Google的官方文档是:

https://developer.android.com/training/system-ui/navigation.html#behind

示例代码

1 View decorView = getWindow().getDecorView();
2 // Hide both the navigation bar and the status bar.
3 // SYSTEM_UI_FLAG_FULLSCREEN is only available on Android 4.1 and higher, but as
4 // a general rule, you should design your app to hide the status bar whenever you
5 // hide the navigation bar.
6 int uiOptions = View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
7               | View.SYSTEM_UI_FLAG_FULLSCREEN;
8 decorView.setSystemUiVisibility(uiOptions);

这里写图片描述

但是,有个问题。

这样的确能隐藏底部虚拟导航栏,但是一旦你点击屏幕,导航栏会出现(持续1秒左右),并且消费掉你的点击事件。如果你要点击一个按钮(导航栏隐藏状态下),你需要连续点两次。因为1秒钟之后,导航栏又消失了,点击屏幕事件会被再次拦截消费。

最终的解决方案

  /**
     * 隐藏虚拟按键,并且全屏
     */
    protected void hideBottomUIMenu() {
        //隐藏虚拟按键,并且全屏
        if (Build.VERSION.SDK_INT > 11 && Build.VERSION.SDK_INT < 19) { // lower api
            View v = this.getWindow().getDecorView();
            v.setSystemUiVisibility(View.GONE);
        } else if (Build.VERSION.SDK_INT >= 19) {
            //for new api versions.
            View decorView = getWindow().getDecorView();
            int uiOptions = View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
                            | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY | View.SYSTEM_UI_FLAG_FULLSCREEN;
            decorView.setSystemUiVisibility(uiOptions);
        }
    }
