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>

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
        }

    }

其他回答

这招对我很管用:

<item name="android:statusBarColor">@android:color/transparent</item>
<item name="android:navigationBarColor">@android:color/transparent</item>
<item name="android:windowTranslucentStatus">false</item>
<item name="android:windowTranslucentNavigation">false</item>

你所需要做的就是在你的主题中设置这些属性:

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

你的活动/容器布局,你希望有一个透明的状态栏需要这个属性集:

android:fitsSystemWindows="true"

这通常是不可能执行这肯定在预kitkat,看起来你可以这样做,但一些奇怪的代码使它如此。

编辑:我推荐这个lib: https://github.com/jgilfelt/SystemBarTint为许多前棒棒糖状态栏颜色控制。

经过深思熟虑,我了解到完全禁用状态栏和棒棒糖导航栏上的半透明或任何颜色的答案是在窗口上设置这个标志:

// In Activity's onCreate() for instance
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
    Window w = getWindow();
    w.setFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS, WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);
}

没有其他主题是必要的,它产生如下内容:

在我的情况下,因为我有一个底部工具栏,我在测试以前的解决方案时遇到了一个问题,android系统按钮覆盖了我的底部菜单 我的解决方案是在活动中添加:

onCreate(Bundle savedInstanceState) super.onCreate (savedInstanceState); //强制全屏模式 requestWindowFeature (Window.FEATURE_NO_TITLE); getWindow () .setFlags (WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN); setContentView (R.layout.main_activity_container);

这应该可以

//在Activity的onCreate()中为实例

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
    Window w = getWindow();
    w.setFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS, WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);
}

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);
}
