kindly note im using adapter custom item layout , here layout -single- list item

<linearlayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:orientation="vertical" android:layout_width="match_parent" android:layout_height="wrap_content" android:background="#00000000" >     <textview         android:id="@+id/product"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:text="@string/txt"         android:textappearance="?android:attr/textappearancelarge"          android:background="#00000000" />     <textview         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:text="@string/sep" />     <textview         android:id="@+id/price"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:text="@string/num" />      <textview         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:paddingleft="5dp"         android:text="@string/currency" />  </linearlayout> 

i using #00000000 in every view stoping transparency , no use

update: have tried .setalpha((float) 0.0); in code , got whole list transparent, in fact want background , not text in it..

you should not setting background @ if want transparent.

if doesn't work may want try:

android:background="@null"
