Android Filter ListView Using BaseAdapter -

we need implement code of filter list view in example. using 2 classes : car.java (contains object car), class caradapter extends baseadapter class. below of codes:

car.java

public class car {  public string title; public int car_id;  public car(string title,int car_id) {     this.title = title;     this.car_id = car_id; }  } 

caradapter.java

public class caradapter extends baseadapter {  private list<car> mcarlist; private layoutinflater minflater;  public caradapter(list<car> list, layoutinflater inflater) {     mcarlist = list;     minflater = inflater; }  @override public int getcount() {     return mcarlist.size(); }  @override public object getitem(int position) {     return mcarlist.get(position); }  @override public long getitemid(int position) {     return position; }  @override public view getview(int position, view convertview, viewgroup parent) {     final viewitem item;      if (convertview == null) {         convertview = minflater.inflate(r.layout.prototype, null);         item = new viewitem();           item.cartitle = (textview) convertview                 .findviewbyid(r.id.textviewprototype);          convertview.settag(item);     } else {         item = (viewitem) convertview.gettag();     }      car curcar = mcarlist.get(position);      item.cartitle.settext(curcar.title);          return convertview; }  private class viewitem {     textview cartitle; }  } 

caractivity.java

 public class activitycar extends activity {  private list<car> mcarlist; private edittext et; /** called when activity first created. */ @override public void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.car);     // obtain reference product catalog     mcarlist = carhelper.getcar(getresources());     // create list     listview listviewcatalog = (listview) findviewbyid(r.id.list_car);     listviewcatalog.setadapter(newcaradapter(mcarlist,getlayoutinflater)));  }    } 

thank help.

follow below steps make listview filterable:

1. in caradapter.java implement filterable interface. take @ similar question answered here.

2. in caractivity.java set listview adapter filterable.
   listviewcatalog.settextfilterenabled(true);

3. if had used android.widget.searchview implement searchview.onquerytextlistener or if used edittext implement textwatcher interface.
