GridView控件setOnItemClickListener不响应点击 [英] GridView setOnItemClickListener does not respond to clicks
本文介绍了GridView控件setOnItemClickListener不响应点击的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我想获得在GridView所选的项目，但是当我点击的项目，没有任何反应。
我不从我的日志code得到任何日志： Log.i（现在的位置，ARG2 +）;
下面是我的code：
calendarView =（GridView控件）this.findViewById（R.id.calendar）;
calendarView.setOnItemClickListener（新OnItemClickListener（）
{
@覆盖
公共无效onItemClick（适配器视图＆LT;＆GT;为arg0，ARG1观，诠释ARG2，
长ARG3）{
// TODO自动生成方法存根
Log.i（现在的位置，ARG2 +）; 按钮TEMP =（按钮）calendarView.getAdapter（）的getItem（ARG2）。 temp.setBackgroundColor（getResources（）的getColor（R.color.LightGreen））;
} }）;

解决方案
我有一个类似的问题。我的方式解决它添加以下行到我的适配器getView（）方法：
btn.setFocusable（假）;
btn.setClickable（假）;
凡BTN是参照按钮。
I am trying to get the selected item in a GridView, but when I click on item, nothing happens.
I don't get any logs from my log code: Log.i("postion", arg2+"");
Here is my code:
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));
}
});
My adapter:
public class GridCellAdapter extends BaseAdapter{
private static final String tag = "GridCellAdapter";
private final Context _context;
private final List<String> list;

解决方案
I have had a similar problem. The way I solved it was adding the following lines to the getView() method in my adapter: btn.setFocusable(false); btn.setClickable(false); Where btn is the reference to the button.
