/* set adapter here */
adapter=new CustomAdapter(MainActivity.this, R.layout.list_row, list);
listSearch.setAdapter(adapter);
/* search here using addtextChangeListener*/
searchText.addTextChangedListener(new TextWatcher() {
@SuppressLint("DefaultLocale")
@Override
public void onTextChanged(CharSequence arg0, int arg1, int arg2, int arg3) {
// TODO Auto-generated method stub
String getText=searchText.getText().toString().trim();
final ArrayList<Model> temp=new ArrayList<Model>();
/* new temp array create and after searching it fill only sarching value*/
temp.clear();

temp.add(odel);
}
}
/* adapter refresh and again set adapter*/
adapter.notifyDataSetChanged();
adapter=new CustomAdapter(MainActivity.this, R.layout.list_row, temp);

/* list item click that show after search*/

CustomAdapter
Simple Array Adapter show data in listview.
public class CustomAdapter extends ArrayAdapter<Model>{
private Context context;
private ArrayList<Model> list;
private int Layout = 0;
public CustomAdapter(Context contx, int resource,
ArrayList<Model> objects) {
super(contx, resource, objects);
// TODO Auto-generated constructor stub
context = contx;
Layout = resource;
list = objects;
}
@Override
public View getView(final int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
ViewHolder viewHolder = null;
if (convertView == null) {
viewHolder = new ViewHolder();
LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = inflater.inflate(Layout, null);
convertView.setTag(viewHolder);
viewHolder.name = (TextView) convertView
.findViewById(R.id.name);
} else {
viewHolder = (ViewHolder) convertView.getTag();
}
try {
viewHolder.name.setText(list.get(position).getName());
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return convertView;
}
class ViewHolder{
TextView name;
}
}
Model Class: value set and get here.
public String name="";
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public Model(String name_) {
// TODO Auto-generated constructor stub
name=name_;
}
}
