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)

将colorPrimaryDark更改为您想要的颜色到res/values/styles.xml文件中

    <resources>
        <color name="colorPrimary">#800000</color>
        <color name="colorPrimaryDark">#303F9F</color> //This Line
        <color name="colorAccent">#FF4081</color>
        <color name="red">#FF0000</color>
        <color name="white">#FFFFFF</color>
       <color name="cream">#fffdd0</color>
       <color name="burgundy">#800000</color>
    </resources>

要改变上面棒棒糖的颜色，只需将其添加到您的styles.xml中

<item name="android:statusBarColor">@color/statusBarColor</item>

但是请记住，如果你想让状态栏有一个浅色，也可以添加这一行

<item name="android:windowLightStatusBar">true</item>

如果你想通过编程方式改变状态栏的颜色(前提是设备有Android 5.0)。 这是一个简单的方法来改变statusBarColor从任何活动 和非常简单的方法，当不同的片段有不同的状态栏颜色。

 /**
 * @param colorId id of color
 * @param isStatusBarFontDark Light or Dark color
 */
fun updateStatusBarColor(@ColorRes colorId: Int, isStatusBarFontDark: Boolean = true) {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
        val window = window
        window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS)
        window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS)
        window.statusBarColor = ContextCompat.getColor(this, colorId)
        setSystemBarTheme(isStatusBarFontDark)
    }
}

/** Changes the System Bar Theme.  */
@RequiresApi(api = Build.VERSION_CODES.M)
private fun setSystemBarTheme(isStatusBarFontDark: Boolean) {
    // Fetch the current flags.
    val lFlags = window.decorView.systemUiVisibility
    // Update the SystemUiVisibility depending on whether we want a Light or Dark theme.
    window.decorView.systemUiVisibility = if (isStatusBarFontDark) lFlags and View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR.inv() else lFlags or View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR
}

Java: 在活动的onCreate方法中使用此方法

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

科特林：

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

此解决方案仅适用于API >= 23。 在API级别30中，setSystemUiVisibility()已弃用。因此你应该像下面这样使用WindowInsetsControllerCompat

fun changeColorStatusBar(color: Int = R.color.white) {
        val window: Window = window
        val decorView = window.decorView
        val wic = WindowInsetsControllerCompat(window, decorView)
        wic.isAppearanceLightStatusBars = true
        // And then you can set any background color to the status bar.
        window.statusBarColor = ContextCompat.getColor(this, color)
    }
