沉浸式模式显示空白区域

我正在尝试实现全屏模式,但对于Android 4.4及更高版本,它会在那里显示一个空白区域:

在沉浸式模式之前(全屏)

和AFTER的toggleFullScreen(假);

如你所见,它不会删除它.这是我用来切换它的代码:

public void toggleFullscreen(boolean fs) {
        if (Build.VERSION.SDK_INT >= 11) {
            // The UI options currently enabled are represented by a bitfield.
            // getSystemUiVisibility() gives us that bitfield.
            int uiOptions = this.getWindow().getDecorView().getSystemUiVisibility();
            int newUiOptions = uiOptions;
            boolean isImmersiveModeEnabled =
                    ((uiOptions | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY) == uiOptions);
            if (isImmersiveModeEnabled) {
                Log.i(getPackageName(), "Turning immersive mode mode off. ");
            } else {
                Log.i(getPackageName(), "Turning immersive mode mode on.");
            }

            // Navigation bar hiding:  Backwards compatible to ICS.
            if (Build.VERSION.SDK_INT >= 14) {
                newUiOptions ^= View.SYSTEM_UI_FLAG_HIDE_NAVIGATION;
            }

            // Status bar hiding: Backwards compatible to Jellybean
            if (Build.VERSION.SDK_INT >= 16) {
                newUiOptions ^= View.SYSTEM_UI_FLAG_FULLSCREEN;
            }

            // Immersive mode: Backward compatible to KitKat.
            // Note that this flag doesn't do anything by itself, it only augments the behavior
            // of HIDE_NAVIGATION and FLAG_FULLSCREEN.  For the purposes of this sample
            // all three flags are being toggled together.
            // Note that there are two immersive mode UI flags, one of which is referred to as "sticky".
            // Sticky immersive mode differs in that it makes the navigation and status bars
            // semi-transparent, and the UI flag does not get cleared when the user interacts with
            // the screen.
            if (Build.VERSION.SDK_INT >= 18) {
                newUiOptions ^= View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY;
            }
            getWindow().getDecorView().setSystemUiVisibility(newUiOptions);
        } else {
            // for android pre 11
            WindowManager.LayoutParams attrs = getWindow().getAttributes();
            if (fs) {
                attrs.flags |= WindowManager.LayoutParams.FLAG_FULLSCREEN;
            } else {
                attrs.flags &= ~WindowManager.LayoutParams.FLAG_FULLSCREEN;
            }
            this.getWindow().setAttributes(attrs);
        }

        try {
            // hide actionbar
            if
                    (this instanceof AppCompatActivity) {
                if (fs) getSupportActionBar().hide();
                else getSupportActionBar().show();
            } else if
                    (Build.VERSION.SDK_INT >= 11) {
                if (fs) getActionBar().hide();
                else getActionBar().show();
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

请检查android:fitsSystemWindows="true"您的布局中没有.

至少它解决了我的情况 - 我在FrameLayout上有适合的SystemWindows.

我是新来的,所以我无法发表评论,但想添加让我对上述解决方案感到沮丧的东西.我一直在检查我的活动及其碎片android:fitsSystemWindows="true",它绝对不存在,但我仍然在底部留有空隙!我疯了!修复这个简单的事情并不难!

事实证明它也出现在我添加的导航抽屉中......所以一定要检查所有的XML!
