wrap_content for a listview's width

Question

Is there a way to have a ListView with the with equal to the longest row? Setting wrap_content for the ListView \'s width has no effect. The ListView covers the whole screen

Answer 1

Sometimes, you know there will always be a limited number of items, maybe 5, maybe 40. In those times you still want to use a ListView and you still want to wrap content.

For those times there is this method:

/**
 * Computes the widest view in an adapter, best used when you need to wrap_content on a ListView, please be careful
 * and don't use it on an adapter that is extremely numerous in items or it will take a long time.
 *
 * @param context Some context
 * @param adapter The adapter to process
 * @return The pixel width of the widest View
 */
public static int getWidestView(Context context, Adapter adapter) {
    int maxWidth = 0;
    View view = null;
    FrameLayout fakeParent = new FrameLayout(context);
    for (int i=0, count=adapter.getCount(); i maxWidth) {
            maxWidth = width;
        }
    }
    return maxWidth;
}

Use it like so (notice I added some extra space to the width just in case):

listView.getLayoutParams().width = getWidestView(mContext, adapter)*1.05;
