ARGB not working properly in Android app -


i trying apply transparent background row when pressed in listview. create file list_selector.xml this:

<selector xmlns:android="http://schemas.android.com/apk/res/android">     <item android:state_pressed="true" android:drawable="@drawable/argb80804040" /> </selector>

and in news_item.xml, define ground follow:

<?xml version="1.0" encoding="utf-8"?> <relativelayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:background="@drawable/list_selector">  <imageview    android:id = "@+id/img"    android:layout_width="95dip"    android:layout_height="75dip"    android:layout_alignparentleft = "true"    android:paddingtop="10dip"    android:layout_marginleft="10dip"    android:paddingbottom="10dip"    android:src="@drawable/no_news_image_small" />       <textview android:id="@+id/title"     android:layout_gravity="center_vertical"     android:layout_width="fill_parent"     android:layout_weight="1.0"     android:layout_height="wrap_content"      android:textsize="12sp"      android:textstyle="bold"     android:paddingtop="5dip"     android:layout_marginleft="110dip"     android:textcolor="#21b6ef"     android:singleline="true" />  <textview android:layout_gravity="center_vertical"     android:layout_width="fill_parent"     android:layout_weight="1.0"     android:layout_height="wrap_content"      android:layout_marginleft="110dip"      android:textsize="10sp"      android:id="@+id/description"      android:layout_below="@id/title"     android:paddingbottom="10dip"      android:layout_marginbottom="5dip"      android:textcolor="#fff"/>  </relativelayout>

however, displays solid color instead of argb color. drawable define follow:

<resources>     <item type="drawable" name="transparent_orange">#64ff7b00</item>     <item type="drawable" name="argb80804040">#80804040</item>     <item type="drawable" name="argb40000000">#40000000</item>     <item type="drawable" name="argb80408040">#80408040</item> </resources>

do need else aplha color working? trying on own device (motorola defy), , using application uses same alpha color , color appears ok in application, in mine, doesnt.

many response t

i don't understand want achieve proposal be

define colors in res/values/colors.xml

<?xml version="1.0" encoding="utf-8"?> <resources>   <color name="transparent_orange">#64ff7b00</color>   ... </resources>

then can define drawable used background in res/drawable/test.xml:

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

finally, can use resulting drawable attribute of target container 

android:background="@drawable/blue_linear_gradient"
