Android Shape Line

Question

I have the following code:

   <shape xmlns:android="http://schemas.android.com/apk/res/android"
   android:shape="line">
   <stroke android:width="1dp"/>
   <size android:height="1dp" />
   <solid  android:color="#FFF"/>
   </shape>


   <LinearLayout
     android:layout_width="fill_parent"
     android:layout_height="wrap_content"
     android:background ="@drawable/line"/>

I have two questions:

1. Why the line is black instead white? I have tried putting it inside a ImageView but the result is the same.
2. How can i set the opacity of the shape?

Answer 1

1) In order to set the color of the line, you need to define android:color on the <stroke>. The <solid> element is for the background.

2) You can set the opacity of the shape by using color values with an alpha layer, aka #ARGB. In your case, maybe #7FFF.
