我试图在 GridView 中获取选定的项目,但是当我单击项目时,没有任何反应。
我没有从我的日志代码中得到任何日志:Log.i("postion", arg2+"");
这是我的代码:
calendarView = (GridView) this.findViewById(R.id.calendar);
calendarView.setOnItemClickListener( new OnItemClickListener()
{
@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
// TODO Auto-generated method stub
Log.i("postion", arg2+"");
Button temp = (Button) calendarView.getAdapter().getItem(arg2);
temp.setBackgroundColor(getResources().getColor(R.color.LightGreen));
}
});
