Linear Layout background not showing at all

Question

I set linear layout background as usual by

android:background="@drawable/xxx"

but it not shown at all both on eclipse as well as on device.

My XML file is given below :

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="horizontal"
    android:weightSum="10" >

    <LinearLayout
        android:layout_width="0dp"
        android:layout_height="fill_parent"
        android:layout_weight="4"
        android:background="#50595f"
        android:orientation="vertical" >

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"

            android:textStyle="bold"
            android:typeface="normal" />

        <ScrollView style="@style/wp_scroll" >

Answer 1

Just guessing, but you may be overriding background attribute in @style/wp_1stLinner

Also, you're missining android:layout_height attribute. Try something like android:layout_height="wrap_content"

Anyway, when nothing else works for me, I try simplifying my xml; you could try leaving just one child (the one with @drawable/shadow_setup); if the background appears, then start adding the rest of the children step by step.

Answer 2

Change

android:layout_width="0dp"

to

android:layout_width="wrap_content"

This should solve your problem

Answer 3

Initially, I had a LinearLayout(with layout_width="match_parent", and layout_height="wrap_content") inside a ScrollView as the only two elements in the XML. I specified android:background="my_color" and it was not working.

So, I just included the entire LinearLayout inside another RelativeLayout, whose layout_width and layout_height were set to "match_parent".

It worked.
