OnItemClickListener using ArrayAdapter for ListView

Question

I want to have an OnItemClickListener for a ListView I create using an ArrayAdapter

This is the code I use to create it:

List<Comment> values = datasource.some_search("Wednesday","11");         ArrayAdapter<Comment> adapter = new ArrayAdapter<Comment>(this,                 android.R.layout.simple_list_item_1, values);         setListAdapter(adapter); 

How do I implement onItemClickListener?

Thanks!

EDIT: I am using in my ArrayAdapter and ListView a string of objects.

EDIT 2: More code:

public void onCreate(Bundle savedInstanceState) {         super.onCreate(savedInstanceState);         setContentView(R.layout.activity_main);            datasource = new CommentsDataSource(this);         datasource.open();         //check if database is populated if NOT, populate with txtToDb();          if (!datasource.isPopulated()) {             // Database is not populated so copy it from assets here             try {                 txtToDb();                 Log.i("Database", "Was not Populated");             } catch (IOException e) {                 // TODO Auto-generated catch block                 e.printStackTrace();                 Log.i("Database", "Was not populated: txtToDb(); failed");              }          } else {             Log.i("Database", "Populated");         }          //wat to show on screen:         List<Comment> values = datasource.search("Wednesday","11");           // Use the SimpleCursorAdapter to show the         // elements in a ListView         ArrayAdapter<Comment> adapter = new ArrayAdapter<Comment>(this,                 android.R.layout.simple_list_item_1, values);         setListAdapter(adapter);      } 

EDIT 3: XML:

<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"     android:layout_width="match_parent"     android:layout_height="match_parent"     android:orientation="vertical" >      <LinearLayout         android:id="@+id/group"         android:layout_width="wrap_content"         android:layout_height="wrap_content" >          <Button             android:id="@+id/add"             android:layout_width="wrap_content"             android:layout_height="wrap_content"             android:text="Add New"              android:onClick="onClick"/>          <Button             android:id="@+id/delete"             android:layout_width="wrap_content"             android:layout_height="wrap_content"             android:text="Delete First"              android:onClick="onClick"/>      </LinearLayout>      <ListView         android:id="@android:id/list"         android:layout_width="match_parent"         android:layout_height="wrap_content"         android:text="@string/hello" />  </LinearLayout>  

Answer 1

Use OnItemClickListener

   ListView lv = getListView();    lv.setOnItemClickListener(new OnItemClickListener()    {       @Override       public void onItemClick(AdapterView<?> adapter, View v, int position,             long arg3)        {             String value = (String)adapter.getItemAtPosition(position);              // assuming string and if you want to get the value on click of list item             // do what you intend to do on click of listview row       }    }); 

When you click on a row a listener is fired. So you setOnClickListener on the listview and use the annonymous inner class OnItemClickListener.

You also override onItemClick. The first param is a adapter. Second param is the view. third param is the position ( index of listview items).

Using the position you get the item .

Edit : From your comments i assume you need to set the adapter o listview

So assuming your activity extends ListActivtiy

     setListAdapter(adapter);  

Or if your activity class extends Activity

     ListView lv = (ListView) findViewById(R.id.listview1);      //initialize adapter       lv.setAdapter(adapter);
