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));
        }
    }

还有一个解决方案:

final View decorView = w.getDecorView();
View view = new View(BaseControllerActivity.this);
final int statusBarHeight = UiUtil.getStatusBarHeight(ContextHolder.get());
view.setLayoutParams(new FrameLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, statusBarHeight));
view.setBackgroundColor(colorValue);
((ViewGroup)decorView).addView(view);

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。

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));
        }
    }

在Values中的colors.xml中将colorPrimary编辑为你想要的状态栏的颜色。例如:

   <resources>
<color name="colorPrimary">#800000</color> // changes the status bar color to Burgundy
<color name="colorPrimaryDark">#303F9F</color>
<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>

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>
