我有这样的需求:通过编程方式改变状态栏的颜色，使其保持透明，以允许导航抽屉绘制自己与透明的状态栏重叠。

我不能用API来做这个

getWindow().setStatusBarColor(ContextCompat.getColor(activity ,R.color.my_statusbar_color)

如果你在stack overflow中检查这一行代码之前的所有人，将状态栏的透明度设置为solid with

getWindow().clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS)

我能够像这样管理状态栏的颜色和透明度:

Android 4: there's not much you can do, because you can't manage status bar color from the API ... the only thing you can do is to set the status bar as translucent and move a colored element of you UI under the status bar. To do this you need to play with android:fitsSystemWindows="false" in your main layout. This allows you to draw you layout under the status bar. Then you need to play with some padding with the top of your main layout. Android 5 and above: you have to define a style with <item name="android:windowDrawsSystemBarBackgrounds">true</item> <item name="android:statusBarColor">@android:color/transparent</item> this allows the navigation drawer to overlap the status bar. Then to change the color keeping the status bar transparent you have to set the status bar color with drawerLayout.setStatusBarBackgroundColor(ContextCompat.getColor(activity, R.color.my_statusbar_color)) where drawerLayout is defined like this <android.support.v4.widget.DrawerLayout android:id="@+id/drawer_layout" android:layout_width="match_parent" android:layout_height="match_parent" android:fitsSystemWindows="true">

Java: 在活动的onCreate方法中使用此方法

Window window = this.getWindow();
window.setStatusBarColor(this.getResources().getColor(R.color.main_screen_bg_color));

科特林：

window.statusBarColor = ContextCompat.getColor(this, R.color.colorName)

我使用这段代码将状态栏更改为透明

    activity?.window?.setFlags(
        WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS,
        WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS
    )

要将其更改为样式中的颜色，请使用以下代码 我在onDetach()中的fragment中使用了

activity?.window?.clearFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS)

<style name="AppTheme" parent="Theme.MaterialComponents.DayNight.DarkActionBar">
    <!-- Primary brand color. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorPrimaryVariant">@color/colorPrimaryDark</item>
    <item name="colorOnPrimary">@color/white</item>
    <!-- Secondary brand color. -->
    <item name="colorOnSecondary">@color/black</item>
    <!-- Status bar color. -->
    <item name="android:statusBarColor" tools:targetApi="l">?attr/colorPrimaryVariant</item>
    <!-- Customize your theme here. -->
</style>

注意:设置colorPrimaryVariant

你可以使用这段简单的代码:

Kotlin中的一行代码:

window.statusBarColor = ContextCompat.getColor(this, R.color.colorName)

原始答案与Java和手动版本检查:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
    getWindow().setStatusBarColor(getResources().getColor(R.color.colorAccentDark_light, this.getTheme()));
} else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
    getWindow().setStatusBarColor(getResources().getColor(R.color.colorAccentDark_light));
}

如果要设置自定义可绘制文件，请使用此代码段

fun setCustomStatusBar(){
    if (Build.VERSION.SDK_INT >= 21) {
        val decor = window.decorView
        decor.viewTreeObserver.addOnPreDrawListener(object :
            ViewTreeObserver.OnPreDrawListener {
            override fun onPreDraw(): Boolean {
                decor.viewTreeObserver.removeOnPreDrawListener(this)
                val statusBar = decor.findViewById<View> 
                  (android.R.id.statusBarBackground)
                statusBar.setBackgroundResource(R.drawable.bg_statusbar)
                return true
            }
        })
    }
}
