Well you should firstly really specify what you really expect as Commons Guy said.

But according to me you can set theme Translucent to achieve that.

Heres a sample in your manifest specify android:style/Theme.Translucent

<!-- Your Custom ListActivity  -->
<activity android:name=".CustomListVIew"
        android:theme="@android:style/Theme.Translucent"/>

now if you want to blur the background, before calling setContentView() from you Custom ListView

public class CustomListActivity extends ListActivity{
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
//NO NEED TO CALL BELOW METHOD IF YOU DON'T WANT BLUR
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_BLUR_BEHIND,
        WindowManager.LayoutParams.FLAG_BLUR_BEHIND);
}
    setContentView(R.layout.main);

Now call you CustomListActivity from your another Activity in onCreate() by

statActivity(new Intent(AcivityA.this,CustomListActivity.class));
