            android:src="@drawable/expand_ico" />
    </RelativeLayout>
</RelativeLayout>
</RelativeLayout>

Note: android:background="@drawable/listview_bg" in my relative layout

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" >

<corners android:radius="12dp" />

<stroke
    android:width="1dp"

Add to your listview_bg.xml this:

<solid
    android:color="@android:color/transparent"/>

Answer 3

Try This Code :-

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
   android:shape="rectangle"> 
<solid android:color="#FFFFFF"/>    
<stroke android:width="3dp"
        android:color="#ed4d44"/>

<corners android:bottomRightRadius="7dp"
         android:bottomLeftRadius="7dp" 
         android:topLeftRadius="7dp"
         android:topRightRadius="7dp"/> 
</shape> 

Answer 4

You have different color on different device because each device have there own default theme thus giving that result.

Solution is to give background color to the relative layout so it is not transparent

Add this in your listview_bg.xml

<solid
        android:color="color" />

Adding solid to you shape xml will fill your shape with your desire color

Answer 5

Use the below drawable to get the desired output,as you are missing solid color in the background of list itemsi.e why you are not getting desired output

<shape xmlns:android="http://schemas.android.com/apk/res/android"
       android:shape="rectangle" >

   <solid android:color="@android:color/white" />

<corners
    android:bottomLeftRadius="8dp"
    android:bottomRightRadius="8dp"
    android:topLeftRadius="8dp"
    android:topRightRadius="8dp" />

<stroke
    android:width="1dp"
    android:color="#6DD8F9" />
