Can't get Uri with getTag


Can't get Uri with getTag

To fix this issue You are setting tag to same view twice; first a Uri and then an integer. Because of this setting Uri as tag is overridden by the integer thus giving ClassCastException. If see carefully then songLay and relativeLayout represents same view.
Remove following line and it would work.
code :
songLay.setTag(position);

wish help you to fix your issue Ken Wolf's answer tells you why it isn't working. To fix it you can simply make that variable a member variable so it can be accessed anywhere in your Activity
code :
public class YourClass extends Activity
{
     int RandomIndex;   // initialize variable here

     public void onCreate(...)
     {
          ...
     }

buttonA.setOnClickListener(new View.OnClickListener() {

    public int GetRandomNumber(int max) {
        int min;
        min = 1;
        int num = min + (int) (Math.random() * ((max - min) + 1));

        return num;
    }

    public void onClick(View view) {

        int countMax = 40;
        RandomIndex = GetRandomNumber(countMax);   // set value here
   }

});
buttonB.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View view) {
            // TODO Auto-generated method stub        
            tv1.setText(String.valueOf(RandomIndex));   // use value here                 
        }
    });

should help you out I used to find myself wanting to use the tag attribute as a convenience method for views. I've since then decided that if you're using the tag attribute as a convenience method, you're not doing it wrong, but there's usually a more elegant workaround.
In your case I'd use a static array of views, and reference the index of the view in the array to access the index of that view. It's even easier if you are working with a ListView or its derivatives using Adapters, and almost laughably easy with an ArrayAdapter, as the views are stored for you, and one can get the index with yourArrayAdapter.getPosition(T item);.
