解决方案

在您的code就需要进行更改，


  1. 您必须添加 im.setOnClickListener（本）; 在的的ImageView 循环

  2. 删除下面的方法

      im.setOnClickListener（新OnClickListener（）{
            公共无效的onClick（视图v）{
                ImageView的IV =（ImageView的）V;
                Log.e（红藤， - ＆gt;中+ iv.getId（））;
            }
        }）;


  3. 覆盖的onClick（）因为你已经实施 onClickcListener 在你的活动。


看看下面code，（和匹配与code知道实际的问题）

解决方案

Just required changes on your code,

  1. You have to add im.setOnClickListener(this); in for loop of ImageView.

  2. Remove below method

    im.setOnClickListener(new OnClickListener() {
        public void onClick(View v) {
            ImageView iv=(ImageView) v;
            Log.e("sfas","-->"+iv.getId());
        }
    });

  3. Override onClick() As you have already implement onClickcListener in your Activity.

Look at below code, (And match with your code to know actual problem)

public class TestActivity extends Activity implements OnClickListener
{
    private static final String TAG_DATA="data";
    private static final String TAG_ADVERTISE="advertisments";
    private static final String TAG_ADVERTISEID="advt_id";
    String advertiseid;
    private static final String TAG_SHOWTEXT="showtext";
    String showtext;
    private static final String TAG_PRODUCTINFO="product_info";
    String productinfo;

    private static final String TAG_THUMBIMAGE="thumbsrc";
    String thumbimage;

    private static final String TAG_DISTANCE="distance";
    String distance;

    private static final String TAG_STIPCIATED="stipciated";
    String stipciated;

    ArrayList<HashMap<String, String>> listadvertise = new ArrayList<HashMap<String,String>>();
    ArrayList<HashMap<String, String>> listadvertise1 = new ArrayList<HashMap<String,String>>();
    ArrayList<HashMap<String, String>> listadvertise2 = new ArrayList<HashMap<String,String>>();
    // Webservice parameter for home advertise
    String url;
    String fbid;
    String latitude;
    String longitude;
    String passdistance;
    String offset;

    // Webservice parameter for stipciated advertise

    String userid;
    String stipciate;
