android - Relative Layouts - long Textview overlaps -

i have relative layout includes 2 textviews:

<relativelayout xmlns:android="http://schemas.android.com/apk/res/android"   xmlns:tools="http://schemas.android.com/tools"   android:id="@+id/container"   android:layout_width="match_parent"   android:layout_height="match_parent"   android:orientation="vertical"   tools:context="com.example.pris.viewactivity"   tools:ignore="mergerootframe">  <textview     android:id="@+id/description"     android:layout_width="wrap_content"     android:layout_height="wrap_content"     android:text="@string/mydes" />  <textview     android:id="@+id/tex"     android:layout_width="wrap_content"     android:layout_height="wrap_content"     android:layout_below="@id/description"     android:text="@string/mytext" />  <autocompletetextview     android:id="@+id/textfield"     android:layout_width="200dip"     android:layout_height="wrap_content"     android:layout_below="@+id/tex"     android:completionthreshold="1"     android:inputtype="text" />  <button     android:id="@+id/but"     android:layout_height="wrap_content"     android:layout_width="wrap_content"     android:text="@string/suchen"     android:layout_torightof="@+id/textfield"     android:layout_alignparentright="true"     android:onclick="addtolist" />  <button     android:id="@+id/but2"     android:layout_weight="1.0"     android:layout_height="wrap_content"     android:layout_width="wrap_content"     android:text="liste löschen"     android:layout_below="@+id/ex"     android:onclick="removelist" />  <listview     android:id="@+id/ex"     android:layout_height="wrap_content"     android:layout_width="wrap_content"     android:layout_weight="1.0"     android:choicemode="singlechoice"     android:layout_below="@+id/but"> </listview> </relativelayout> 

i inserted "description" recently, text there quite long - , overlaps below it.

how can change that?

i not want change whole layout if possible, , unfortunately not possible shorten text.

have tried put scrollview above relativelayout?

<scrollview xmlns:android="http://schemas.android.com/apk/res/android"     android:layout_width="match_parent"     android:layout_height="match_parent"> </scrollview> 

also, check end of .xml, missing closing tag
