How to make transparent gradient?

Question

I have the following gradient:

<?xml version="1.0" encoding="utf-8"?>     <shape xmlns:android="http://schemas.android.com/apk/res/android">         <gradient              android:startColor="#ECECEC"             android:centerColor="#F6F6F4"             android:endColor="#F8F8F6"             android:angle="90"             android:dither="true"          />     </shape> 

I want this to be transparent because in my ListView I am setting this as my ListSelector:

<ListView android:layout_width="fill_parent"                 android:layout_height="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android"                 android:id="@+id/ARListView"                  android:background="@drawable/transparent_background"                  android:cacheColorHint="#00000000" android:drawSelectorOnTop="true"                  android:listSelector="@drawable/stocks_selected_gradient"> </ListView> 

Answer 1

Just use an 8-digit color value, e.g. #FFF8F8F6, where the first two characters are the alpha value. FF being fully opaque, and 00 being fully transparent.
