        android:padding="5dip" 
        android:orientation="vertical" >

<!--  Post Aavatar + time + username  -->
 <RelativeLayout
    android:layout_width="fill_parent"
    android:layout_height="wrap_content">

        <ImageView
            android:id="@+id/postbit_useravatar"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentRight="true"
            android:clickable="true"
            android:focusable="true"
            android:src="@drawable/no_avatar" />

        <TextView
            android:id="@+id/postbit_username"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginLeft="30dip"
            android:layout_marginRight="5dip"
            android:layout_marginTop="5dip"
            android:layout_toLeftOf="@+id/postbit_useravatar"
            android:ellipsize="end"
            android:singleLine="true"
            android:text="sss"
            android:textDirection="rtl"
            android:gravity="right"
            android:textAppearance="?android:attr/textAppearanceSmall"
            android:textColor="#000000" />

        <ImageView
            android:id="@+id/postbit_boxmenu"
            android:clickable="true"
            android:focusable="true"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentLeft="true"
            android:src="@drawable/mini_menu" />

        <TextView
            android:id="@+id/postbit_timestamp"
            android:layout_marginRight="5dip"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:textColor="#b9b9b9"
            android:layout_toLeftOf="@+id/postbit_useravatar"
            android:layout_below="@+id/postbit_username"
            android:text="timestamp"
            android:textAppearance="?android:attr/textAppearanceSmall" />

     </RelativeLayout>  
<!-- // Post User Aavatar + time + username -->




   </LinearLayout>


</LinearLayout>

and this is forum_box_bit.xml

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
    <shape android:shape="rectangle">
    <solid android:color="#c4c5c6" />
    <corners android:radius="1dp"/>
    </shape>
</item>
<item android:bottom="2dp">
    <shape android:shape="rectangle">
    <solid android:color="#ffffff"/>
    <corners android:radius="1dp"/>
    </shape>
</item>
</layer-list>

通常您必须将选择器设置为背景。什么是“forum_box_bit”，这是一个选择器吗？如果未在您的 drawables 文件夹中定义一个，如下例所示：

      <?xml version="1.0" encoding="utf-8"?>
        <selector xmlns:android="http://schemas.android.com/apk/res/android" >

       <item 
          android:state_pressed="false"
          android:drawable="@drawable/default_shape"></item>
       <item
          android:state_pressed="true"
          android:drawable="@drawable/pressed_shape"></item>

       <item 
         android:drawable="@drawable/default_shape"></item>

    </selector>

您可以定义一个像图像一样的背景或为此选择器创建一些 xml 形状。

对于某些形状，在可绘制文件夹中为按下状态定义一个形状，为未按下状态定义一个形状：

按下（pressed_shape.xml）：

    <?xml version="1.0" encoding="utf-8"?>
       <shape xmlns:android="http://schemas.android.com/apk/res/android" >
         <gradient 
            android:startColor="@color/dark_orange_pressed"
            android:endColor="@color/light_orange_pressed"/>
       <corners 
          android:radius="5dp"/>
       <stroke 
         android:color="@color/light_gray"
         android:width="2dp"/>
    </shape>

未按下（default_shape.xml）：

    <?xml version="1.0" encoding="utf-8"?>
        <shape xmlns:android="http://schemas.android.com/apk/res/android" >
        <gradient 
            android:startColor="@color/dark_orange"
            android:endColor="@color/light_orange"/>
    <corners 
            android:radius="5dp"/>
    <stroke 
            android:color="@color/light_gray"
            android:width="2dp"/>
    </shape>

并定义颜色，在您的值文件夹中创建一个 xml，它必须命名为“colors.xml”：

    <?xml version="1.0" encoding="utf-8"?>
       <resources>

         <color name="dark_orange">#f6801c</color>
         <color name="light_orange">#f1a84a</color>
         <color name="light_gray">#cfcfcf</color>
         <color name="dark_orange_pressed">#b07d3b</color>
         <color name="light_orange_pressed">#d29648</color>

       </resources>
