Android隐藏底部虚拟按键并全屏

Java

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

kotlin

 window.decorView.apply {
        // Hide both the navigation bar and the status bar.
        // SYSTEM_UI_FLAG_FULLSCREEN is only available on Android 4.1 and higher, but as
        // a general rule, you should design your app to hide the status bar whenever you
        // hide the navigation bar.
        systemUiVisibility = View.SYSTEM_UI_FLAG_HIDE_NAVIGATION or View.SYSTEM_UI_FLAG_FULLSCREEN
    }

动态设置

 private void hideSystemNavigationBar() {
        if (Build.VERSION.SDK_INT > 11 && Build.VERSION.SDK_INT < 19) {
            View view = this.getWindow().getDecorView();
            view.setSystemUiVisibility(View.GONE);
        } else if (Build.VERSION.SDK_INT >= 19) {
            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);
        }
    }
