android - ListView rows disappear when adding a RelativeLayout below a ListView -

here's simplified version of portrait ui want layout:

it's listview above layout.

the complication want whole bottom layout (in case 'button2') visible when lots of lines added edittext:

i've been trying achieve nesting relativelayout inside linearlayout. unfortunately, listview disappears when effect want edittext, e.g.

i've tried loads of alternatives, nothing seems achieve both goals.

here's xml:

<?xml version="1.0" encoding="utf-8"?> <relativelayout xmlns:android="http://schemas.android.com/apk/res/android"     android:id="@+id/main"     android:layout_width="match_parent"     android:layout_height="match_parent" >      <framelayout         android:id="@+id/aaa"         android:layout_width="match_parent"         android:layout_height="wrap_content" >     </framelayout>      <linearlayout         android:id="@+id/bbb"         android:layout_width="match_parent"         android:layout_height="wrap_content"         android:layout_below="@+id/aaa"         android:orientation="vertical" >          <linearlayout             android:id="@+id/list_container"             android:layout_width="match_parent"             android:layout_height="0dip"             android:layout_weight="1" >              <listview                 android:id="@+id/list"                 android:layout_width="match_parent"                 android:layout_height="match_parent"                 android:entries="@array/list_items"/>         </linearlayout>          <relativelayout             android:id="@+id/input_parent"             android:layout_width="match_parent"             android:layout_height="wrap_content" >              <button                 android:id="@+id/button1"                 android:layout_above="@+id/bottom_layout"                 android:layout_width="100dip"                 android:layout_height="50dip"                 android:clickable="true"                 android:text="button1" />              <edittext                 android:id="@+id/edittext"                 android:layout_above="@+id/bottom_layout"                 android:layout_torightof="@+id/button1"                 android:layout_width="match_parent"                 android:layout_height="wrap_content"                 android:minheight="50dip"                 android:imeoptions="flagnoextractui"                 android:inputtype="textmultiline"                 android:maxlines="8"                 android:scrollbars="vertical" />              <!-- align bottom when input text area gets                  big doesn't push section off screen  -->             <linearlayout                 android:id="@+id/bottom_layout"                 android:layout_alignparentbottom="true"                 android:layout_width="match_parent"                 android:layout_height="wrap_content"                 android:orientation="vertical" >                  <button                     android:id="@+id/button2"                     android:layout_width="match_parent"                     android:layout_height="150dip"                     android:layout_gravity="bottom"                     android:clickable="true"                     android:text="button2" />              </linearlayout>          </relativelayout>      </linearlayout>  </relativelayout> 

if remove android:layout_alignparentbottom="true" bottom_layout listview contents appears, lose effect want edittext.

can help? need support os 2.2+.

simplifying layout bit this:

<?xml version="1.0" encoding="utf-8"?> <relativelayout xmlns:android="http://schemas.android.com/apk/res/android"                 android:id="@+id/main"                 android:layout_width="match_parent"                 android:layout_height="match_parent" >      <framelayout             android:id="@+id/aaa"             android:layout_width="match_parent"             android:layout_height="wrap_content" >     </framelayout>      <relativelayout             android:id="@+id/bbb"             android:layout_width="match_parent"             android:layout_height="wrap_content"             android:layout_below="@+id/aaa"             android:orientation="vertical" >              <listview                     android:id="@+id/list"                     android:layout_above="@+id/edittext"                     android:layout_width="match_parent"                     android:layout_height="match_parent"                     android:entries="@array/list_items"/>              <button                     android:id="@+id/button1"                     android:layout_above="@+id/bottom_layout"                     android:layout_width="100dip"                     android:layout_height="50dip"                     android:clickable="true"                     android:text="button1" />              <edittext                     android:id="@+id/edittext"                     android:layout_above="@+id/bottom_layout"                     android:layout_torightof="@+id/button1"                     android:layout_width="match_parent"                     android:layout_height="wrap_content"                     android:minheight="50dip"                     android:imeoptions="flagnoextractui"                     android:inputtype="textmultiline"                     android:maxlines="8"                     android:scrollbars="vertical" />              <!-- align bottom when input text area gets                  big doesn't push section off screen  -->             <linearlayout                     android:id="@+id/bottom_layout"                     android:layout_alignparentbottom="true"                     android:layout_width="match_parent"                     android:layout_height="wrap_content"                     android:orientation="vertical" >                  <button                         android:id="@+id/button2"                         android:layout_width="match_parent"                         android:layout_height="150dip"                         android:layout_gravity="bottom"                         android:clickable="true"                         android:text="button2" />             </linearlayout>      </relativelayout>  </relativelayout> 

seems give result describing.
