Three questions about images

[Dov Ezra]

Hi,
I hope you people can share your knowlage about the fallowing questions.

1. I have a Linear Layout with a background image and an ImageView component in it.
is it possible to add a new image that will stand in front of the Image View?

2. I have a Grid Layout containing nine numeric images, each have a white background image behind it:

Class KeypadAdapter extends adapter{
...
public View getView(int position, View convertView, ViewGroup parent) {
        ImageView imageView;
        if (convertView == null) {  // if it's not recycled, initialize some attributes
            imageView = new ImageView(m_context);
            imageView.setLayoutParams(new GridView.LayoutParams(28, 28));
            imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
            imageView.setPadding(3, 3, 3, 3);
        } else {
            imageView = (ImageView) convertView;
        }

        imageView.setImageResource(R.drawable.number);
        imageView.setBackgroundResource(R.drawable.keypad_key);
        return imageView;
}

the problem here is how to scale the white background, but not the image with the number.
I can change the line imageView.setLayoutParams(new GridView.LayoutParams(28, 28));
to something like imageView.setLayoutParams(new GridView.LayoutParams(58, 28));
but this stretch both the number and the white background.
I attach a file with two screen shots. the top one is what I'm trying to achieve and the bottom is what I have now.

3. how do I set an application icon? android documentation says I have to add this line
to my manifest file: <application android:icon="@drawable/icon" >
where drawable/icon refer to a png file named "icon". well, I have that png file, put it in res/drawable
and add that line to the manifest. no result. I don't see my icon but that green default android icon.
what is missing here?

Thanks,
Dov

This sounds correct. Try uninstalling the app, and then install a clean build (do an ant clean before the actual build) - there could be some caching going on.

Icon problem solved.
the problem is the way eclipse look for the icon file.
Although I had the icon.png in res/drawable, I didn't have it on res/drawable-hdp,
res/drawable-ldp and res/drawable-mdp. those folders contained only the default green icon.

now its working fine. :-)
