Answer 1

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;

    int screenheight;
    int screenwidth;
    AlertDialog alertDialog;
    private ProgressDialog progressDialog;
    ImageView imagemenu;
    ScrollView scrollView3;


    private ListView listViewLeft;

    {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(R.layout.test);

        alertDialog = new AlertDialog.Builder(this).create();
        DisplayMetrics screensize= new DisplayMetrics();
        getWindowManager().getDefaultDisplay().getMetrics(screensize);

        screenheight=screensize.heightPixels;
        screenwidth=screensize.widthPixels;

        Log.e("Screen Height","---->"+screenheight);
        Log.e("Screen Width ","---->"+screenwidth);

        RelativeLayout headerlLayout = (RelativeLayout)findViewById(R.id.headerlayout);
        headerlLayout.setLayoutParams(new RelativeLayout.LayoutParams(LayoutParams.FILL_PARENT,((screenwidth*8)/100)+10));

        if(CheckConnection.getInstance(this).isOnline(this))
        {

        //  new HomeAsyncTask().execute("");
        }
        else

        imagemenu=(ImageView)findViewById(R.id.imagemenu);

            {
                scrollView3.scrollTo(0, 200);
            }
        });

        homelistlayout1=(LinearLayout)findViewById(R.id.homelistlayout1);
        homelistlayout1.setPadding(0, 100, 0, 0);
        homelistlayout2=(LinearLayout)findViewById(R.id.homelistlayout2);

        for(int i=0;i<12;i++)
        {
            im= new ImageView(TestActivity.this);
            im.setLayoutParams(new LinearLayout.LayoutParams(200, 200));
            im.setOnClickListener(this); 
            if(i%2==0)
            {
                    im.setImageResource(R.drawable.adv);
                    im.setId(i);

            }
        }   
       }
   }

@Override
public void onClick(View v) {
  Log.e("Clicked","----->"+v.getId());
  switch (v.getId()) 
   {
    case 1:
        Log.e("Clicked","----->"+v.getId());
        break;
    case 2:
        break;
    .
    .

    default:
    break;
 }
}

Answer 2

You can setId() when you create the view and then that's his ID. http://developer.android.com/reference/android/view/View.html#setId(int)

Answer 3

You are setting the ID's for the ImageView with im.setId(i); . So the ID's would be the value of i. You can keep track of this somewhere.

Also, please post only the relevant pieces of the code and not the whole class
