Android 如何在ViewPager中单击项目

如何在ViewPager中单击项目。我想返回我单击的当前项目的位置。例如，我尝试运行下一个代码：

pager.setOnClickListener(new OnClickListener() {
        public void onClick(View v) {
        Toast toast = Toast.makeText(getApplicationContext(),
            pager.getCurrentItem(), Toast.LENGTH_SHORT);
        toast.show();
        }
    });

但是什么也没发生。我在点击ViewPager的布局时已经准备好了所有的书面选项。也许有人能告诉我，我做错了什么？

为什么不将onclick侦听器添加到片段中。然后广播一个意图

public class Your extends  Fragment
{
 @Override
 public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle  savedInstanceState) {
    super.onCreateView(inflater, container, savedInstanceState);
    View inflatedView = inflater.inflate(R.layout.customlayout, null);
    inflatedView.setOnClickListener(new OnClickListener() {
    public void onClick(View v) {
    Intent temp =  new Intent("anything.com.com.CHECK_CURRENT_PAGE_ITEM");
    getActivity().sendBroadcast(temp);
    }
    });
    }
}

然后在您的主要活动中注册一个广播接收器

public class Youractivity extends FragmentActivity
{

private BroadcastReceiver clickedReceiver = new BroadcastReceiver() {

    @Override
    public void onReceive(Context context, Intent intent) {
        Toast toast = Toast.makeText(getApplicationContext(),
        pager.getCurrentItem(), Toast.LENGTH_SHORT);
    }
};

@Override
public void onCreate()
{
...
   registerBroadcstReceiver(clickedReceiver, new IntentFilter("anything.com.com.CHECK_CURRENT_PAGE_ITEM"))

...
}
@Override
public void onDestroy()
{
unregisterBroadcastReceiver()
}
}
