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:

我刚在这里找到的

因为它已经经过了6年,默认的minSDKAPI是21(棒棒糖)*CMIIW。下面是我总结透明状态栏并且不与导航按钮重叠的方法:

fun setStatusBarTransparent(activity: Activity, view: View) {
    activity.apply {
        window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS)
        window.statusBarColor = ContextCompat.getColor(this, R.color.transparent)
        WindowCompat.setDecorFitsSystemWindows(window, false)
        ViewCompat.setOnApplyWindowInsetsListener(view) { root, windowInset ->
            val inset = windowInset.getInsets(WindowInsetsCompat.Type.systemBars())
            root.updateLayoutParams<ViewGroup.MarginLayoutParams> {
                leftMargin = inset.left
                bottomMargin = inset.bottom
                rightMargin = inset.right
                topMargin = 0
            }
            WindowInsetsCompat.CONSUMED
        }
    }
}

要再次显示状态栏只需要做一些更改:

fun setStatusBarShown(activity: Activity, view: View) {
    activity.apply {
        window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS)
        window.statusBarColor = ContextCompat.getColor(this, R.color.transparent)
        WindowCompat.setDecorFitsSystemWindows(window, false)
        ViewCompat.setOnApplyWindowInsetsListener(view) { root, windowInset ->
            val inset = windowInset.getInsets(WindowInsetsCompat.Type.systemBars())
            val inset1 = windowInset.getInsets(WindowInsetsCompat.Type.statusBars())
            root.updateLayoutParams<ViewGroup.MarginLayoutParams> {
                leftMargin = inset.left
                bottomMargin = inset.bottom
                topMargin = inset1.top
                rightMargin = inset.right
            }
            WindowInsetsCompat.CONSUMED
        }
    }
}

我把这个函数放在对象类称为UiUtils,所以当我在我的活动调用该函数(我使用视图绑定太)。它看起来是这样的:

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    ...
    UiUtils.setStatusBarTransparent(this, bind.root)
    ...
}

希望我的回答能帮助到你们:)

我在调查这个图书馆的时候找到了答案: https://github.com/laobie/StatusBarUtil

因此,您需要将以下代码添加到您的活动

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
    window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS)
    window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS)
    window.addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION)
    window.statusBarColor = Color.TRANSPARENT
} else {
    window.addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS)
}

实现状态栏完全透明: 首先在themes.xml中创建自定义主题为

 <style name="QuiloThemeLight" parent="Theme.AppCompat.Light.NoActionBar">

Java:

    getWindow().clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
    getWindow().addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
    getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);
    getWindow().setStatusBarColor(Color.TRANSPARENT);

芬兰湾的科特林:

activity.window.apply {
        clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS)
        addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS)
        decorView.systemUiVisibility = View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
        statusBarColor = Color.TRANSPARENT
    }

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);
}

你只需要进入mainactivity。java


protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        Window g = getWindow();
        g.setFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS, WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);

        setContentView(R.layout.activity_main);

    }

虽然上面所有的答案都围绕着相同的基本思想,但你可以使用上面的一个例子来实现简单的布局。然而,我想改变背景的颜色,同时使用滑动的“全屏”(标签栏除外)片段导航,并保持常规的导航,标签和操作栏。

在仔细阅读Anton Hadutski的一篇文章后,我更好地理解了发生了什么。

我有DrawerLayout与ConstraintLayout(即容器),其中有工具栏,包括主要片段和BottomNavigationView。

设置DrawerLayout有fitsSystemWindows为true是不够的,你需要同时设置DrawerLayout和ConstraintLayout。假设状态栏是透明的,状态栏的颜色现在与ConstraintLayout的背景色相同。

然而,所包含的片段仍然有状态栏的嵌入,所以在上面动画另一个“全屏”片段并不会改变状态栏的颜色。

引用文章中的一小段代码到Activity的onCreate中:

ViewCompat.setOnApplyWindowInsetsListener(findViewById(R.id.container)) { view, insets ->
        insets.replaceSystemWindowInsets(
                insets.systemWindowInsetLeft,
                0,
                insets.systemWindowInsetRight,
                insets.systemWindowInsetBottom
        )
    }

一切都很好,除了现在工具栏不处理状态栏的高度。更多的参考文章,我们有一个完整的工作解决方案:

val toolbar = findViewById<Toolbar>(R.id.my_toolbar)
    ViewCompat.setOnApplyWindowInsetsListener(findViewById(R.id.container)) { view, insets ->
        val params = toolbar.layoutParams as ViewGroup.MarginLayoutParams
        params.topMargin = insets.systemWindowInsetTop
        toolbar.layoutParams = params
        insets.replaceSystemWindowInsets(
                insets.systemWindowInsetLeft,
                0,
                insets.systemWindowInsetRight,
                insets.systemWindowInsetBottom
        )
    }

main_activity.xml(请注意,工具栏中的marginTop是为了预览,它将被代码所取代):
