How do you implement action listener on listView?

Question

I have been struggling for days trying to find the proper way to implement an action listener to a ListView. What I really want to accomplish is to create a ListView and whenever the user clicks any item, the previous Activity will be switched. I am really new at this so please help me, I would really appreciate it a lot. If you can tell me the what I'm doing wrong on my code that would be awesome!

I am using Fedor's code from [here][1].

        ///Here I tried to Implement an action listener but It doesn't work.

        list.setOnItemClickListener(new OnItemClickListener() {                                                                                                                                                             
            public void onItemClick(AdapterView<?> arg0, View arg1, int position,long id)                               
            {                                                                                                                                                                           
                if(list.getItemAtPosition(position).equals(mStrings[1]))                                                       
                {                                                                                                           
                    Intent i = new Intent(MainActivity.this, Activity2.class);                                                                                        
                    startActivity(i);                                                                                
                    }                                                                                                    
                }                                                                                                       
            });


      }

You need to override onListItemClick in such a case. Refer to Click Listener on ListView for more help, the solution is a fairly good implementation.

Here is a possible implementation that should go in your Main activity. Please keep in mind that this will only work as long as you keep MainActivity extending Activity.

@Override
protected void onListItemClick(ListView l, View v, int position, long id) {
    super.onListItemClick(l, v, position, id);
     // Intent launcher here
}

If you wish to extend ListActivity instead of Activity later on and you need to call to onListItemClick, do it following this scheme

public class YourClass extends ListActivity implements OnItemClickListener{

@Override
public void onCreate(Bundle icicle){
    super.onCreate(icicle);
    setContentView(R.layout.your_layout);

    getListView().setOnItemClickListener(this);
}

@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
    // your stuff here
}
}
