google maps - How to add info window for clustering marker in android? -

i referred this google map android . want show info window image markers in android.

myitem class

import com.google.android.gms.maps.model.latlng; import com.google.maps.android.clustering.clusteritem;  public class myitem implements clusteritem {  private latlng mposition; private string mlatitude = ""; private string mstorelogo = ""; private string mlongitude = "";  @override public latlng getposition() {     return mposition; }  public void setposition(latlng mposition) {     this.mposition = mposition; }  public latlng getmposition() {     return mposition; }  public void setmposition(latlng mposition) {     this.mposition = mposition; }   public string getmlatitude() {     return mlatitude; }  public void setmlatitude(string mlatitude) {     this.mlatitude = mlatitude; }  public string getmlongitude() {     return mlongitude; }  public void setmlongitude(string mlongitude) {     this.mlongitude = mlongitude; }  public string getmstorelogo() {     return mstorelogo; }  public void setmstorelogo(string mstorelogo) {     this.mstorelogo = mstorelogo; }  } 

youractivity class :

public class map extends fragmentactivity implements         clustermanager.onclusterclicklistener<myitem>,         clustermanager.onclusterinfowindowclicklistener<myitem>,         clustermanager.onclusteritemclicklistener<myitem>,         clustermanager.onclusteriteminfowindowclicklistener<myitem> {       private clustermanager<myitem> mclustermanager;

    }   }   } 

the code self explanatory. hooe had added cluster library , google play services lib build path. please let me know if have queries.
