I have a shape drawable that I want to use as a background. I want the shape to be transparent. But so far it's not. How do I do that? Here is what I have:
<?xml version="1.0" encoding="utf-8"?> <shape xmlns:android="http://schemas.android.com/apk/res/android"
android:padding="10dp"
android:shape="rectangle" >
<solid android:color="#80000000" />
<stroke
android:width="1dip"
android:color="#000000" />
<corners android:radius="10dp" />
</shape>
I expected the line <solid android:color="#80000000" /> to do the trick.
EDIT:
In manifest, I set android:theme="@android:style/Theme.Dialog". Could that be the cause of the problem? I am basically trying to get this view on top of another. Changing to 00 or FF or whatever else does not work.
if you want set shape background to transparent you need to set this color
<solid android:color="#00000000" />
for creating a color including an opacity effect, you can create a color
with taking the alpha channel into account.
<resources>
<color name="translucent_grey">#88cccccc</color>
</resources>
a quote from another User about the color formats:
When defining the color of a view in android, the format can be either #RRGGBB or #AARRGGBB, where AA is the hex alpha value. FF would be fully opaque and 00 would be full transparent.
more information about this technique can be found in this thread:

You can use this :
<solid
android:color="@android:color/transparent"/>
This is working for me.
I found the answer. Direct quote:
The easiest way that I have found is to set the activity's theme in the AndroidManifest to android:theme="@android:style/Theme.Holo.Dialog" then in the activity's onCreate method call getWindow().setBackgroundDrawable(new ColorDrawable(0));
