Solution 1:

what you want to do is in the LinearLayout do android:layout_above="@+id/Chatbox" that will make sure it does not go below it

Solution 2:

//try this its working fine for me

<LinearLayout
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <TextView
        android:id="@+id/PreviousChatsButton"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:focusable="true"
        android:gravity="center_horizontal"
        android:padding="5dip"
        android:text="ViewPreviousChats" >
    </TextView>

    <ListView
        android:id="@android:id/list"
        android:layout_width="fill_parent"
        android:layout_height="0dp" 
        android:layout_weight="1"/>

    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" >

        <TextView
            android:id="@+id/NoChatsMsg"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_centerHorizontal="true"
            android:layout_centerVertical="true"
            android:text="@string/NoNewChatMsg" />

        <Button
            android:id="@+id/SubmitButton"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentBottom="true"
            android:layout_alignParentRight="true"
            android:onClick="SubmitButtonClick"
            android:text="@string/Submit" />

        <EditText
            android:id="@+id/Chatbox"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignBaseline="@id/SubmitButton"
            android:layout_alignBottom="@id/SubmitButton"
            android:layout_alignParentLeft="true"
            android:layout_toLeftOf="@id/SubmitButton"
            android:ems="10"
            android:inputType="text" >
        </EditText>
    </LinearLayout>
</LinearLayout>

Solution 3:

Use android:layout_above to avoid this problem :

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

    <Button
        android:id="@+id/SubmitButton" ... />

    <LinearLayout     
         android:layout_above="@id/SubmitButton" ... >
         ...
    </LinearLayout>

Note that you have to declare your button before the LinearLayout for this to work.
