Android Listview Onclick

By using setOnClickItemListener() we can get the clicked item in listview.


To add a listview to your XML file check out my other thread....



Listview OnClick Example -
Your Java code should look like
***************************************
public class ListviewOnclickExample extends Activity
02{
03 private ListView lv1;
04 private String lv_arr[]={"Android","iPhone","BlackBerry","AndroidPeople","J2ME","Listview","ArrayAdapter","ListItem","Us","UK","India"};
05 @Override
06 public void onCreate(Bundle icicle)
07 {
08 super.onCreate(icicle);
09 setContentView(R.layout.main);
10 lv1=(ListView)findViewById(R.id.ListView01);
11 lv1.setAdapter(new ArrayAdapter(this,android.R.layout.simple_list_item_1 , lv_arr));
12 lv1.setTextFilterEnabled(true);
13 lv1.setOnItemClickListener(new OnItemClickListener() {
14 @Override
15 public void onItemClick(AdapterView a, View v, int position, long id) {
16 Builder adb=new AlertDialog.Builder(ListviewOnclickExample.this);
17 adb.setTitle("LVSelectedItemExample");
18 adb.setMessage("Selected Item is = "+lv1.getItemAtPosition(position));
19 adb.setPositiveButton("Ok", null);
20 adb.show();
21 }
22 });
23 }
24}
