What is frame layout in android?

FrameLayout is designed to block out an area on the screen to display a single item.

What is Z order in Android?

In Android starting from API level 21, items in the layout file get their Z order both from how they are ordered within the file, as described in correct answer, and from their elevation, a higher elevation value means the item gets a higher Z order.

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" />

you can just add translation for Z as you want(1dp,2pd,...) like:

<ImageView
    android:id="@+id/imageView0"
    android:layout_width="110dp"
    android:layout_height="110dp"
    android:layout_marginTop="25dp"
    android:contentDescription="@string/desc"
    android:translationZ="1dp"
    app:srcCompat="@drawable/ic_icon" />
