Android List View Tutorial

Introduction of Android List View

Android provides data display in form of list. That purpose we use list view.

How to define

• make a string list

   static final String[] STATES = new String[] 
   { "Rajasthan", "Delhi", "Bombay","MP", "UP"};
   

  
  
  Above we formed list of indian states.
• Then set list adapter with our string list.
  
  setListAdapter(new ArrayAdapter<String>(this, R.layout.main,STATES));
• Then get list object

   ListView listView = getListView();
   

• Using above listview set listener

   listView.setOnItemClickListener(new OnItemClickListener() {
   public void onItemClick(AdapterView<?> parent, View view,
  					int position, long id) {
  					
  					your code;
  					
  					}
   
   });
   

Example Above text view set list in text view.

1. Make layout file(main.xml).
   
   

   <?xml version="1.0" encoding="utf-8"?>
   
   <TextView xmlns:android="http://schemas.android.com/apk/res/android"
       android:layout_width="fill_parent"
       android:layout_height="fill_parent"
       android:padding="10dp"
       android:textSize="10sp">
    
   <TextView/>
   

2. Define list and add listener that show item

   public class ListStateActivity extends ListActivity {
    
   	static final String[] STATES = new String[] { "Rajasthan", "Delhi", "Bombay",
   			"MP", "UP"};
    
   	@Override
   	public void onCreate(Bundle savedInstanceState) {
   		super.onCreate(savedInstanceState);
    
   		// no more this
   		// setContentView(R.layout.main);
    
   setListAdapter(new ArrayAdapter<String>(this, R.layout.main,STATES));
    
   ListView listView = getListView();
   listView.setTextFilterEnabled(true);
    
   listView.setOnItemClickListener(new OnItemClickListener() {
   			

   public void onItemClick(AdapterView<?> parent, View view,
   					

   int position, long id) {

   // When clicked, show a toast with the TextView text

   Toast.makeText(getApplicationContext(),
   ((TextView) view).getText(), Toast.LENGTH_SHORT).show();
   			}
   		});
    
   	}
    
   }
