Android - 为带有导航抽屉和应用栏的应用完全隐藏状态和导航栏

Question

如何完全动态隐藏状态和导航栏？

该应用包含一个带有应用栏/工具栏和 FAB 按钮的常规导航抽屉。

切换到全屏时，导航和状态栏的内容被滚动掉了。屏幕上留下两个空栏。我想让那些空条隐藏起来。

我创建了一个 minimal demo app。左边是常规应用程序。在 fab 上推送时，应用程序应全屏显示。

如何隐藏栏？

问题：请写出最小演示项目中需要进行哪些更改？

已更新第二个解决方案：

@Roaim 提供的 GREAT 解决方案有效。重要的是将 android:fitsSystemWindows 布局属性设置为 false。

如果您仍然无法显示和隐藏 status/navigation 条，此解决方案可能会对您有所帮助。

完全隐藏条形图：

public static void hideSystemUI() {
    if (getSupportActionBar() != null) {
        getSupportActionBar().hide();
    }
    getWindow().getDecorView().setSystemUiVisibility(
            View.SYSTEM_UI_FLAG_IMMERSIVE
                    | 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);
}

并显示所有柱状图：

public static void showSystemUI() {
    if (getSupportActionBar() != null) {
        getSupportActionBar().show();
    }
    getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
    getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_VISIBLE);
}

Answer 1

进入价值观>风格

现在应用内主题使用

让导航栏transculate

<item name="android:windowTranslucentNavigation">true</item>

要删除它，请使其颜色与您的布局相匹配

<item name="android:navigationBarColor">@color/white</item>

或者试试这个

public void FullScreencall() {
    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;
        decorView.setSystemUiVisibility(uiOptions);
    }
}

更新

问题出在您的布局文件上。我只是设置 android:fitsSystemWindows=false 来解决这个问题。我对您的存储库进行了 pull request，我认为这可以解决您的问题。

您应该遵循以下官方文档：

Hide the Status Bar on Android 4.0 and Lower

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        // If the Android version is lower than Jellybean, use this call to hide
        // the status bar.
        if (Build.VERSION.SDK_INT < 16) {
            getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                    WindowManager.LayoutParams.FLAG_FULLSCREEN);
        }
        setContentView(R.layout.activity_main);
    }
    ...
}

Hide the Status Bar on Android 4.1 and Higher

    View decorView = getWindow().getDecorView();
    // Hide the status bar.
    int uiOptions = View.SYSTEM_UI_FLAG_FULLSCREEN;
    decorView.setSystemUiVisibility(uiOptions);
    // Remember that you should never show the action bar if the
    // status bar is hidden, so hide that too if necessary.
    ActionBar actionBar = getActionBar();
    actionBar.hide();

Hide the Navigation Bar

    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);

Answer 3

试试这个...

<style name="MyApp" parent="Theme.MaterialComponents.Light.NoActionBar">
 ...
 <item name="windowNoTitle">true</item>
 <item name="windowActionBar">false</item>
 <item name="android:windowFullscreen">true</item>
 ...
 </style>

Answer 4

试试这个 hide/show 状态栏和导航栏，它们都是 SystemUI 的一部分。

fun setSystemUIVisibility(hide: Boolean) {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.R) {
        val window = window.insetsController!!
        val windows = WindowInsets.Type.statusBars() or WindowInsets.Type.navigationBars()
        if (hide) window.hide(windows) else window.show(windows)
        // needed for hide, doesn't do anything in show
        window.systemBarsBehavior = WindowInsetsController.BEHAVIOR_SHOW_TRANSIENT_BARS_BY_SWIPE
    } else {
        val view = View.SYSTEM_UI_FLAG_HIDE_NAVIGATION or
                View.SYSTEM_UI_FLAG_FULLSCREEN or
                View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY
        window.decorView.systemUiVisibility = if (hide) view else view.inv()
    }
}
