在kotlin中，我能够使用以下方法解决这个问题:

  window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS)
  window.statusBarColor = ContextCompat.getColor(this, android.R.color.transparent)

这就是我在奇巧(KitKat)的做法，而且效果不错。

public static void setTaskBarColored(Activity context) {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT)
        {
            Window w = context.getWindow();
            w.setFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS, WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
            //status bar height
            int statusBarHeight = Utilities.getStatusBarHeight(context);

            View view = new View(context);
            view.setLayoutParams(new FrameLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT));
            view.getLayoutParams().height = statusBarHeight;
            ((ViewGroup) w.getDecorView()).addView(view);
            view.setBackgroundColor(context.getResources().getColor(R.color.colorPrimaryTaskBar));
        }
    }

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)
    }

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>

如果你想在Android 4.4及以上版本上工作，试试这个。我参考了Harpreet的答案和这个链接。Android和透明的状态栏

首先，在Activity的onCreate方法中调用setStatusBarColored方法(我把它放在util类中)。我在这里用了一张图片，你可以用颜色来改变它。

public static void setStatusBarColored(Activity context) {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT)
    {
        Window w = context.getWindow();
        w.setFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS, WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
        int statusBarHeight = getStatusBarHeight(context);

        View view = new View(context);
        view.setLayoutParams(new FrameLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT));
        view.getLayoutParams().height = statusBarHeight;
        ((ViewGroup) w.getDecorView()).addView(view);
        view.setBackground(context.getResources().getDrawable(R.drawable.navibg));
    }
}

public static int getStatusBarHeight(Activity context) {
    int result = 0;
    int resourceId = context.getResources().getIdentifier("status_bar_height", "dimen", "android");
    if (resourceId > 0) {
        result = context.getResources().getDimensionPixelSize(resourceId);
    }
    return result;
}

之前:

后:

状态栏的颜色已经改变了，但是导航栏被切断了，所以我们需要在onCreate方法中设置导航栏的边距或偏移量。

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
        LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(
                ViewGroup.LayoutParams.MATCH_PARENT, (int)(this.getResources().getDimension(R.dimen.navibar_height)));
        layoutParams.setMargins(0, Utils.getStatusBarHeight(this), 0, 0);

        this.findViewById(R.id.linear_navi).setLayoutParams(layoutParams);
    }

然后状态栏将是这样的。
