Android List View

Here i am going to explain about using list view in android. Please follow the steps given below Step 1 Create a new project and open the activity class. The default code will be like this

public class BasicListViewActivity extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); } }

Step 2 Add list activity as given in the below Step 3 Declare a string array as given below

static final String[]alphabets = new String[]{"A- Apple", "B- Blackberry", "C- Chat", "D- Download", "E- Email", "F- Facebook", "G- Google", "H- HewlettPackard", "I- Iphone", "J- Java", "K- Kingston", "L- Linkedin" };

Step 4 Instead of content view, add list adapter with the list item give the string array as input.

public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setListAdapter(new ArrayAdapter(this, android.R.layout.simple_list_item_1, alphabets)); getListView().setTextFilterEnabled(true); }

Note: “setTextFilterEnabled(true)” is used to enable text filter option. Step 5 Here is the code for on click functionality for list items.

protected void onListItemClick(ListView l, View v, int position, long id) { super.onListItemClick(l, v, position, id); Object obj = this.getListAdapter().getItem(position); String selectedtext = obj.toString(); Toast.makeText(this, "You have clicked: " + selectedtext, Toast.LENGTH_LONG).show(); }

Step 6 Now run your application. Here is your output. You can download the full project here
