linearlayout edittext on bottom overlays content of scrollview, filled programmatically. how avoid please? have simplified xml in vain in first version of message. have added full code now

i'd keep edittext height expandable.

any ideas please? thanks!

i suggest using relative layout parent. , add rule above.

<relativelayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical">  <scrollview     android:id="@+id/scroll"     android:layout_width="fill_parent"     android:layout_height="fill_parent"     android:layout_above="@+id/llbutton"     android:orientation="vertical">      <linearlayout         android:id="@+id/linear"         android:layout_width="match_parent"         android:layout_height="match_parent"         android:orientation="vertical">      </linearlayout> </scrollview>  <linearlayout     android:id="@+id/llbutton"     android:layout_width="match_parent"     android:layout_height="wrap_content"     android:layout_alignparentbottom="true"     android:orientation="horizontal">      <edittext         android:id="@+id/editmessage"         android:layout_width="fill_parent"         android:layout_height="wrap_content"         android:layout_gravity="center_vertical|center_horizontal"          android:gravity="top|left"         android:inputtype="textmultiline|textcapsentences"         android:maxlines="5"         android:minlines="3"         android:scrollhorizontally="false" />      <button         android:id="@+id/buttonsend"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:layout_gravity="center_vertical|center_horizontal"         android:gravity="center"         android:text='send'         android:textappearance="?android:attr/textappearancemedium" /> </linearlayout>
