Question

I’m working on relative layout. Basically i would like to put my ticker(lnrTicker) and the footer(txtFooter) at the bottom of the screen. Everything works file, except the ticker clips off some bottom portion of wvRight element. So i figured out that probably i’ll have to put android:layout_above=”@id/lnrTicker”, in the wvRight component. But whenever i do that, i see compilation error stating that cannot find resource “lnrTicker”. How can i achieve the layout, or is there something i’m missing in understanding to layout_above. Here is my layout file

    <?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/relMain"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:padding="0dp"
    android:background="@color/black">
    <WebView 
        android:id="@+id/wvHeader"
        android:layout_height="wrap_content"
        android:layout_width="fill_parent"  
        android:visibility="gone"       
        android:scrollbars="none"/>     
    <WebView 
        android:id="@+id/wvLeft"
        android:layout_width="300dp"
        android:layout_height="fill_parent"
        android:scrollbars="none"
        android:visibility="gone"
        android:layout_below="@id/wvHeader"/>   
    <WebView 
        android:id="@+id/wvRight"
        android:layout_width="wrap_content"
        android:layout_height="fill_parent"
        android:scrollbars="none"           
        android:layout_toRightOf="@id/wvLeft"
        android:layout_below="@id/wvHeader"
        android:layout_above="@id/lnrTicker"/>
    <LinearLayout 
        android:id="@+id/lnrTicker"
        android:orientation="horizontal" 
        android:layout_width="fill_parent"      
        android:layout_height="60dp"        
        android:layout_below="@id/wvRight"/>
    <TextView
        android:id="@+id/txtFooter"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"        
        android:textSize="8sp"
        android:layout_below="@id/lnrTicker"
        android:layout_alignParentBottom="true"/>   
</RelativeLayout>

Is it possible to add android:layout_above=”@id/lnrTicker”, at runtime to wvRight component?

Answer 1

Is it possible to add android:layout_above="@id/lnrTicker", at runtime to wvRight component?

Yes.

<WebView android:layout_above="@+id/lnrTicker"

then later

<LinearLayout android:id="@id/lnrTicker"

The difference is that you’re declaring the android:id for the first time in @id/wvRight and thus will need the +.
