在Android的GridView中更改图像的背景资源

Question

here am trying to change the background resource for the image, am success in that, but the problem is, when i clicking on all the items in the gridview every item has changes in the background resource, my question is if i click on item which is 0 position it has to change the background resource image, and again if i click on the item which is in 1 position it has to change the background resource and as well as a image on 0 position has to set normal image like without background resource comes to normal state.

public void onItemClick(AdapterView<?> arg0, View vv, int arg2, long arg3) {
        // TODO Auto-generated method stub

        vv.setBackgroundResource(android.R.drawable.btn_default);


    } 

Provide me to set only one selected item has to change the image. Thanks in advance.

Answer 1

You need modify your adapter to set background for checked items. For Example:

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    // creating view

    if(item.isChecked()){
        veiw.setBackgroundResource(android.R.drawable.btn_default);
    }

    return view;
}
