本文详细介绍了如何使用新API控制Android系统的系统UI隐藏，并展示了如何实现WindowManager下全屏显示的技巧，包括设置DecorFitsSystemWindows、WindowInsetsController和系统状态监听。涉及的技术包括ViewCompat、WindowInsetsControllerCompat和WindowManager.LayoutParams。

新API

 //fun Activity.hideSystemUI() {
        //     WindowCompat.setDecorFitsSystemWindows(window, false)
        //     ViewCompat.getWindowInsetsController(window.decorView)?.let { controller ->
        //         controller.hide(WindowInsetsCompat.Type.systemBars())
        //         controller.systemBarsBehavior =
        //               WindowInsetsControllerCompat.BEHAVIOR_SHOW_TRANSIENT_BARS_BY_SWIPE
        //     }
        //}
        getWindow().setDecorFitsSystemWindows(false);
        WindowCompat.setDecorFitsSystemWindows(getWindow(), false);
        WindowInsetsControllerCompat windowInsetsControllerCompat = WindowCompat.getInsetsController(getWindow(), getWindow().getDecorView());
        if (windowInsetsControllerCompat != null) {
            windowInsetsControllerCompat.addOnControllableInsetsChangedListener((controller, typeMask) -> {
                controller.hide(WindowInsetsCompat.Type.systemBars());
                controller.setSystemBarsBehavior(WindowInsetsControllerCompat.BEHAVIOR_SHOW_TRANSIENT_BARS_BY_SWIPE);
            });
        }

 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
                        | View.INVISIBLE);
//监听SystemUI变化，动态强制隐藏systemUI
getWindow().getDecorView().setOnSystemUiVisibilityChangeListener(new View.OnSystemUiVisibilityChangeListener() {
            @Override
            public void onSystemUiVisibilityChange(int visibility) {
                
            }
        });

WindowManager addView 设置全屏

mParams = new WindowManager.LayoutParams();
        mParams.systemUiVisibility = 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
                | View.INVISIBLE;
        mAddView = View.inflate(mContext, R.layout.dialog_framelayout, null);
        mWindowManager.addView(mAddView, mParams);
