Question

gridview中的item项里有个imageview,点击item之后如何设置imageview为选中状态或者更换imageview的背景

Answer 1

给GridView添加item选中监听
gridview.setOnItemClickListener(new MyOnItemClickListener());
监听类里重载onItemClick方法，
class MyOnItemClickListener implements AdapterView.OnItemClickListener {
@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
arg0.getItemAtPosition(arg2) 这个就是你所选中的item，想干嘛干嘛
}
