对此，

推荐答案

您的XML不包含您的外部布局，但我认为它是一个相对的布局。在 RelativeLayout的，元素'Z级别由它们添加到容器中的顺序确定。视图中添加以后会在上面。试试你的滑动抽屉移动到你的外容器的底部。这样的 -

Your xml does not contain your outer layout, but I assume it is a relative layout. In a RelativeLayout, the elements' z levels are determine by the order they are added to the container. View added later will be on top. Try moving your sliding drawer to the bottom of your outer container. Like this --

<ListView android:id="@+id/listView1"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:stackFromBottom="true"
    android:transcriptMode="alwaysScroll"
    android:layout_above="@+id/InnerRelativeLayout"
    android:layout_alignParentTop="true" 
/>  
 <RelativeLayout 
    android:id="@+id/InnerRelativeLayout"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true" >
    <Button 
        android:text="kirim" 
        android:id="@+id/button_send"
        android:layout_alignParentRight="true" 
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:onClick="tambahItems"          
        >

    </Button>           
</RelativeLayout> 

<com.ltvie.chat.MultiDirectionSlidingDrawer
    xmlns:my="http://schemas.android.com/apk/res/com.ltvie.chat"
    android:id="@+id/drawer"
    my:direction="topToBottom"
    android:layout_width="fill_parent"
    android:layout_height="match_parent"
    my:handle="@+id/handle"
    my:content="@+id/content"
    >
   <include
        android:id="@id/content"
        layout="@layout/pen_content"
        android:gravity="top"           
        />
     <ImageView
        android:id="@id/handle"
        android:layout_width="wrap_content"
        android:layout_height="5dp"
        android:src="@drawable/sliding_drawer_handle_bottom" />          
</com.ltvie.chat.MultiDirectionSlidingDrawer>
