[android-beginners] Re: Background Image for a (semi-transparent) List
Thanks guys for you help. (I've already rated David's answer - was a
big help!)
I also would like to know if this is possible:
A list, which is semi-transparent printed on a background image! That
background image should change when ever the device is rotated to it's
widescreen outfit. You should see the background image and also the
list entrie about it. (65% opacity)
Can someone give me some hints where to start... I've already checked
the API demos...
I'm in the early beginning of a small private project and would like
to know if it's possible to create software that has that UI... ;)
Thanks very much in advance,
Sascha

Try this:
row.xml:
TextView xmlns:android=http://schemas.android.com/apk/res/android;
android:id=@android:id/text1 android:paddingTop=2dip
android:paddingBottom=3dip android:layout_width=fill_parent
android:layout_height=wrap_content /
:
This is similar to Android's simple_list_item_1 layout.
Then, remove the line:
setContentView(R.layout.main);
The content view is already being set when connecting this class to the
ArrayAdapter. Resetting it to main will make it blank.
Hope this helps,

Hi Sascha,
I'm not an expert yet at this, but I did look into your problem. Perhaps
you are forgetting to use the ListActivity's own ListView? Code below

work.
