Android完全透明的状态栏?

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:

你可以使用下面的代码使状态栏透明。 见图片，红色高亮，帮助您识别使用下面的代码

你的android应用程序的Kotlin代码片段

步骤:1在“On create Method”中写下代码

if (Build.VERSION.SDK_INT >= 19 && Build.VERSION.SDK_INT < 21) {
    setWindowFlag(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS, true)
}
if (Build.VERSION.SDK_INT >= 19) {
    window.decorView.systemUiVisibility = View.SYSTEM_UI_FLAG_LAYOUT_STABLE or View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
}
if (Build.VERSION.SDK_INT >= 21) {
    setWindowFlag(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS, false)
    window.statusBarColor = Color.TRANSPARENT
}

你需要SetWindowFlag方法，在下面的代码中描述。

private fun setWindowFlag(bits: Int, on: Boolean) {
    val win = window
    val winParams = win.attributes
    if (on) {
        winParams.flags = winParams.flags or bits
    } else {
        winParams.flags = winParams.flags and bits.inv()
    }
    win.attributes = winParams
}

android应用程序的Java代码片段:

Step1:主活动代码

if (Build.VERSION.SDK_INT >= 19 && Build.VERSION.SDK_INT < 21) {
    setWindowFlag(this, WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS, true);
}
if (Build.VERSION.SDK_INT >= 19) {
    getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_STABLE | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);
}

if (Build.VERSION.SDK_INT >= 21) {
    setWindowFlag(this, WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS, false);
    getWindow().setStatusBarColor(Color.TRANSPARENT);
}

Step2: SetWindowFlag方法

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

其他回答

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:

用于谷歌的最后一次更新。这是我的代码。这将是透明的状态栏和导航栏: 把你的主题改为:

 <style name="Theme.Pink" 
 parent="Theme.MaterialComponents.DayNight.NoActionBar">
    <!-- Primary brand color. -->
    <item name="colorPrimary">@color/pink_primary</item>
    <item name="colorPrimaryVariant">@color/pink_dark</item>
    <item name="colorOnPrimary">@color/black</item>
    <!-- Secondary brand color. -->
    <item name="colorSecondary">@color/pink_light</item>
    <item name="colorSecondaryVariant">@color/pink_primary</item>
    <item name="colorOnSecondary">@color/black</item>
    <item name="android:textColor">?attr/colorOnPrimary</item>
    <!-- Status bar color. -->
    <!-- Customize your theme here. -->
 //transparent statusbar
    <item name="android:windowTranslucentStatus">true</item>
    <item name="android:windowIsTranslucent">true</item>
//transparent navigationbar
    <item name="android:windowTranslucentNavigation">true</item> 
 </style>

然后在layout (file xml)中:添加2个属性point_top和point_bottom来确定应用程序其他组件的边距值的位置:

    <androidx.constraintlayout.widget.ConstraintLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@drawable/bg_activity">

    <TextView
        android:id="@+id/point_top"
        android:layout_width="0dp"
        android:layout_height="0dp"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

    

    <TextView
        android:id="@+id/point_bottom"
        android:layout_width="0dp"
        android:layout_height="0dp"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent" />
   
       <.....>

   </androidx.constraintlayout.widget.ConstraintLayout>

然后在baseActivity或yourActivity中:在onCreate中添加以下代码:

 override fun onCreate(savedInstanceState: Bundle?) {
   
    super.onCreate(savedInstanceState)
    binding = setLayout()
    //set inset for view
    ViewCompat.setOnApplyWindowInsetsListener(binding.root) { _, insets ->
        val paramsTop =
            findViewById<TextView>(R.id.point_top).layoutParams as MarginLayoutParams
        paramsTop.setMargins(0, insets.getInsets(WindowInsetsCompat.Type.systemBars()).top, 0, 0)
        findViewById<TextView>(R.id.point_top).layoutParams = paramsTop
        val paramsBottom =
            findViewById<TextView>(R.id.point_bottom).layoutParams as MarginLayoutParams
        paramsBottom.setMargins(0, 0, 0, insets.getInsets(WindowInsetsCompat.Type.systemBars()).bottom)
        findViewById<TextView>(R.id.point_bottom).layoutParams = paramsBottom
        insets.consumeSystemWindowInsets()

    }

    setContentView(binding.root)
}

希望这对大家有所帮助。

在你的XML中使用这段代码，你将能够在你的活动中看到时间条:

<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true">

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:)

这仅适用于API级别>= 21。这对我很管用。 这是我的代码(Kotlin)

override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
        findViewById<View>(android.R.id.content).systemUiVisibility =
                View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN or View.SYSTEM_UI_FLAG_LAYOUT_STABLE
}
