我搜索了文档,但只找到了这个: 链接。这是用来使酒吧半透明?我想做的是使状态栏完全透明(如下图所示),并使它向后兼容APK<19:

我的styles.xml:

<resources xmlns:tools="http://schemas.android.com/tools">

  <style name="AppTheme" parent="Theme.AppCompat.Light">
  <item name="android:actionBarStyle">@style/ThemeActionBar</item>
  <item name="android:windowActionBarOverlay">true</item>
  <!-- Support library compatibility -->
  <item name="actionBarStyle">@style/ThemeActionBar</item>
  <item name="windowActionBarOverlay">true</item>
  </style>

  <style name="ThemeActionBar" parent="Widget.AppCompat.Light.ActionBar.Solid">
  <item name="android:background"> @null </item>
  <!-- Support library compatibility -->
  <item name="background">@null</item>
  <item name="android:displayOptions"> showHome | useLogo</item>
  <item name="displayOptions">showHome|useLogo</item>

  </style>

</resources>

我能做的是:


当前回答

如果你使用的是React Native,那么其他帖子就不起作用了。React有自己的处理方法。

<StatusBar半透明backgroundColor="transparent" /> from react-native是正确的方法,感谢这篇文章,这将覆盖App中的android设置。

然而,有两件事需要知道:

如果你从react-native-elements中使用<Header />组件,它已经包含了<StatusBar />,使用它的statusBarProps代替。 如果你正在使用WIX react-native-navigation,他们有一个单独的方式来处理状态栏,参考这个和这个。他们说它与React Native不兼容,然而,看起来他们一起工作对我来说很好。

完全透明的状态栏和导航栏

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    transparentStatusAndNavigation();
}


private void transparentStatusAndNavigation() {
    //make full transparent statusBar
    if (Build.VERSION.SDK_INT >= 19 && Build.VERSION.SDK_INT < 21) {
        setWindowFlag(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS
                | WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION, true);
    }
    if (Build.VERSION.SDK_INT >= 19) {
        getWindow().getDecorView().setSystemUiVisibility(
                View.SYSTEM_UI_FLAG_LAYOUT_STABLE
                        | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                        | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
        );
    }
    if (Build.VERSION.SDK_INT >= 21) {
        setWindowFlag(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS
                | WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION, false);
        getWindow().setStatusBarColor(Color.TRANSPARENT);
        getWindow().setNavigationBarColor(Color.TRANSPARENT);
    }
}

private void setWindowFlag(final int bits, boolean on) {
    Window win = getWindow();
    WindowManager.LayoutParams winParams = win.getAttributes();
    if (on) {
        winParams.flags |= bits;
    } else {
        winParams.flags &= ~bits;
    }
    win.setAttributes(winParams);
}

试试下面的代码:

private static void setStatusBarTransparent(Activity activity) {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
        activity.getWindow().addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
        activity.getWindow().clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
        activity.getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);
        activity.getWindow(). setStatusBarColor(Color.TRANSPARENT);
    } else {
        activity.getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
    }
}

只需将这行代码添加到你的主java文件中:

getWindow().setFlags(
    WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS,
    WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS
);

这是一个简单的方法,我找到了很多搜索。

步骤1

在你的主题里放这个项目

        <item name="android:statusBarColor" tools:targetApi="lollipop">@android:color/transparent</item>

步骤2

主要活动

WindowCompat.setDecorFitsSystemWindows(window, false)

非常重要,如果你使用底部导航栏

在一些设备中,API 30+ u会发现系统导航栏与底部导航栏重叠,如果在你的应用中使用它。

这就解决了这个问题。

  if (Build.VERSION.SDK_INT >= 30) {
        // Root ViewGroup of my activity
        val root = findViewById<ConstraintLayout>(R.id.root)

        ViewCompat.setOnApplyWindowInsetsListener(root) { view, windowInsets ->

            val insets = windowInsets.getInsets(WindowInsetsCompat.Type.systemBars())

            // Apply the insets as a margin to the view. Here the system is setting
            // only the bottom, left, and right dimensions, but apply whichever insets are
            // appropriate to your layout. You can also update the view padding
            // if that's more appropriate.

            view.layoutParams =  (view.layoutParams as FrameLayout.LayoutParams).apply {
                leftMargin = insets.left
                bottomMargin = insets.bottom
                rightMargin = insets.right
            }

            // Return CONSUMED if you don't want want the window insets to keep being
            // passed down to descendant views.
            WindowInsetsCompat.CONSUMED
        }

    }

下面的代码将使你的状态栏和导航栏透明(注意,这将使你的布局成为像游戏中使用的布局一样的全屏布局):

@Override
public void onWindowFocusChanged(boolean hasFocus) {
    super.onWindowFocusChanged(hasFocus);
    if (hasFocus) {
        hideSystemUI();
    }
}

private void hideSystemUI() {
    // Enables sticky immersive mode.
    // For "lean back" mode, remove SYSTEM_UI_FLAG_IMMERSIVE_STICKY.
    // Or for regular immersive mode replace it with SYSTEM_UI_FLAG_IMMERSIVE
    View decorView = getWindow().getDecorView();
    decorView.setSystemUiVisibility(
            View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY
                    // Set the content to appear under the system bars so that the
                    // content doesn't resize when the system bars hide and show.
                    | View.SYSTEM_UI_FLAG_LAYOUT_STABLE
                    | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
                    | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                    // Hide the nav bar and status bar
                    | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
                    | View.SYSTEM_UI_FLAG_FULLSCREEN);
}
