Android通知栏颜色改变方法

1、android 沉浸式状态栏

通知栏（notification）背景颜色跟随app导航栏（top title）背景颜色变化而变化。这也叫沉浸式状态栏，这是Google在android 4.4以上的系统提出的。

Activity中添加如下代码：

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {  getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);  getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);  
} 

布局文件中的导航条添加如下属性：

android:clipToPadding="false"  
android:fitsSystemWindows="true"

2、改变通知栏颜色

当时要的就是这个，而搜到的很多都是沉浸效果。沉浸效果相当于隐藏了通知栏，对整个屏幕进行了拉伸，这时不仅自己的导航栏要考虑通知栏的高度，还要考虑4.4以下的Android系统无法沉浸通知栏的情况。另外，对于有虚拟按键Android设备的底部也会被沉浸，这并不是我们想要的。
下面是我整理的代码：

public class Utility {/** * 改变通知栏颜色*/public static void setActionBar(Context context){if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {setTranslucentStatus(context, true);}SystemBarTintManager tintManager = new SystemBarTintManager((Activity) context);tintManager.setStatusBarTintEnabled(true);tintManager.setStatusBarTintResource(R.color.action_bar);}@TargetApi(19) public static void setTranslucentStatus(Context context, boolean on) {Window win = ((Activity)context).getWindow();WindowManager.LayoutParams winParams = win.getAttributes();final int bits = WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS;if (on) {winParams.flags |= bits;} else {winParams.flags &= ~bits;}win.setAttributes(winParams);}
}

在Activity的onCreate中调用上面方法

Utility.setActionBar(this);

同时在xml布局最外层添加下面的属性

android:fitsSystemWindows="true"
