自定义的drawable

text\_angle\_gray.xml

<?xml version="1.0" encoding="utf-8"?>
    <layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
    
        
        <item>
            <shape>
                <solid android:color="#CCCCCC" />
            </shape>
        </item>
        
        <item
            android:bottom="1dp"
            android:top="1dp"
            android:left="1dp"
            >
            
            <shape>
                <solid android:color="@color/page_backgroup" />
            </shape>
        </item>
    
    </layer-list>

text\_angle.xml，是实现圆角效果的

<?xml version="1.0" encoding="utf-8"?>
    <shape xmlns:android="http://schemas.android.com/apk/res/android">
        <solid android:color="#FFFFFFFF"/>
         <corners android:radius="0dp"/>
        <stroke 
            android:color="#CCCCCC"
            android:width="0.01dp" />
    </shape>

text\_angle\_right.xml

<?xml version="1.0" encoding="utf-8"?>
    <layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
    
        
        <item>
            <shape>
                <solid android:color="#CCCCCC" />
            </shape>
        </item>
        
        <item
            android:bottom="1dp"
            android:top="1dp"
            android:right="1dp"
            >
            
            <shape>
                <solid android:color="@color/page_backgroup" />
            </shape>
        </item>
    
    </layer-list>

然后，实现这个ui

<?xml version="1.0" encoding="utf-8"?>
    <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@color/bg_White"
        android:focusable="true"
        android:focusableInTouchMode="true" >
    
    
        <RelativeLayout
            android:layout_width="match_parent"
            android:layout_height="@dimen/height_top_bar"
            android:background="@color/top_bar_normal_bg"
            android:gravity="center_vertical" >
    
            <TextView
                android:id="@+id/tv_back"
                android:layout_width="wrap_content"

            android:layout_height="match_parent"
            android:layout_marginTop="50dp" >

    	*
    	*简介
    	AsyncTask可以使得使用UI线程变的更容易更适当，它可以在后台运行一些操作然后在UI上展现，不用操作具体的线程和handlers
    	一个 asynchronous task包括三种基本类型（调用参数，进度和结果），和四个步骤（调用开始，在后台运行，处理进度，结束）
    	), and most often will override a second one (onPostExecute(Result).)
    
    	使用方法描述
    	Asynchronous Task必须是作为一个子类来使用，
    	task实例必须在UI线程创建
    	execute(Params...)必须在UI线程调用
    	不要手工调用onPreExecute(), onPostExecute(Result), doInBackground(Params...), onProgressUpdate(Progress...)。
    	task只可以execute一次，执行多次就报异常
