Balloon chat application issues

I am doing a simple chat application and I want to show balloons similar to the iphone's sms app.

So I am doing an Activity with a ListView with a certain layout. This are my layouts:

/* Activity Layout */ 
 <LinearLayout android:orientation="vertical"
       android:layout_width="fill_parent"
       android:layout_height="fill_parent"
    >

     <ListView android:id="@+id/chat_log"
         android:layout_width="fill_parent"
         android:layout_height="fill_parent"
         android:stackFromBottom="true"
         android:layout_marginTop="50dp"
         android:transcriptMode="alwaysScroll"
         android:layout_weight="1"
         android:cacheColorHint="#00000000"
         android:clickable="false"
     />

     <LinearLayout android:orientation="horizontal"
         android:layout_width="fill_parent"
         android:layout_height="wrap_content"
     >

   <EditText android:id="@+id/chat_input_text"
             android:layout_width="wrap_content"
             android:layout_height="wrap_content"
             android:layout_weight="1"
             androi开发者_Go百科d:layout_gravity="bottom"
         />

         <Button android:id="@+id/chat_send_button"
             android:layout_width="wrap_content"
             android:layout_height="wrap_content"
             android:text="@string/chat_send_button"
         />

     </LinearLayout>
 </LinearLayout>

Other:

/* Row Layout */
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
 android:id="@+id/userprofile_view"
 android:layout_width="wrap_content"
 android:layout_height="wrap_content"
 android:background="@drawable/chat_ballon_left" >

 <TextView
  android:id="@+id/chat_message"
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:paddingLeft="2dp"
  android:text="haasdasdasdasdasdasdasdoo" />
</FrameLayout>

Here's the result.

My issues:

• The gray line which I would like to remove.
• Text is not using the whole space.
• Somehow even thought I've added android:clickable="false" the balloons are clickable.

---

The FrameLayout is unnecessary, so use the TextView as a root element (with the chat_ballon_left background of course). Set the width to match_parent so that the text takes the whole space.

BTW nice baloons, don't forget to have hdpi versions too :)
