在使用Notification自定义布局时，代码实现为：
notification.contentView = new RemoteViews(mContext.getPackageName(), R.layout.content_view);
如果app运行到这行代码时出现如下错误：
android.app.RemoteServiceException Bad notification posted from package com.mypackage.test: Couldn't expand RemoteViews for: StatusBarNotification(pkg=com.mypackage.test user=UserHandle{0} id=-1314 tag=null score=0 key=0|com.haier.uhome.uplus|-1314|null|10471|0: Notification(pri=0 contentView=null vibrate=null sound=null defaults=0x0 flags=0x62 color=0xff607d8b vis=PRIVATE)) TestRes=null
那很有可能在自定义的布局R.layout.content_view中有不支持的布局或控件。官方自定义通知栏RemoteViews只支持以下布局和控件：
布局容器Layout:
FrameLayout,LinearLayout,RelativeLayout,GridLayout
控件Component:
AnalogClock,Button,Chronometer,ImageButton,ImageView,ProgressBar,
TextView,ViewFlipper,ListView,GridView,StackView,AdapterViewFlipper
修改布局文件，使其符合上述的条件即可。
