今天又看到了另外一种设置沉浸式标题栏的方式，比上次写的那个使用主题，设置主题背景色的要好很多了。尤其是设置主题背景色后，程序从后台到前台ui界面没加载出来会显示出短暂的标题栏的颜色，因此设置主题背景颜色的方式还是有些缺陷。
废话不多说，我介绍的这个方法使用了小米的一个类：SystemBarTintManager
小米官网的地址 http://dev.xiaomi.com/doc/p=4769/index.html
经过测试在其他的手机上一样适用，只是那个设置标题栏字体颜色为黑色不能用而已。

使用起来也很简单，在你的activity或者baseactivity的oncreate方法中加入以下代码：
1 if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
2 setTranslucentStatus(true);
3 }
4 mTintManager = new SystemBarTintManager(this);
5 mTintManager.setStatusBarTintEnabled(true);
6 //使StatusBarTintView 和 actionbar的颜色保持一致，风格统一。
7 mTintManager.setStatusBarTintResource(R.color.navbar);
8 // 设置状态栏的文字颜色
9 mTintManager.setStatusBarDarkMode(false, this);
setTranslucentStatus方法
1 @TargetApi(19)
2 protected void setTranslucentStatus(boolean on) {
3 Window win = getWindow();
4 WindowManager.LayoutParams winParams = win.getAttributes();
5 final int bits = WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS;
6 if (on) {
7 winParams.flags |= bits;
8 } else {
9 winParams.flags &= ~bits;
10 }
11 win.setAttributes(winParams);
12 }
然后需要在你的布局文件最外层添加以下代码
1 android:fitsSystemWindows="true"
2 android:clipToPadding="false" 这个在设置主题的那里是设置为true的，注意区分
如果你只用了普通的activity，那么一切事情都已经结束了。但我做的司信项目，在主界面上用的是一个activitygroup，然后用tabhost添加了4个activity，这样的话会有一些出入，需要在activitygroup的方法上写上以上代码，activity继承了baseactivity，因此也加入了这些属性，会造成自定义的导航栏文字显示不全。
这个时候就再调用一下
mTintManager.setStatusBarTintEnabled(false);//把自定义的titlebar设置不显示 这样就可以了，效果是与之前的一样的，因此不再贴图。好处就是不会忽然闪一下之前的红色背景了。
