title: start new activity on click listview item
body: <p>I need some help to do a simple click in a listview item to open a new Activity. I have seen a lot of this kinda issues here but no one helped me.</p>
  
  <pre><code>public class CustomListView extends ListActivity {
  
      private EfficientAdapter adap;
      ...
  
      @Override
      public void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
          requestWindowFeature(Window.FEATURE_NO_TITLE);
          setContentView(R.layout.main);
  
          adap = new EfficientAdapter(this);
          setListAdapter(adap);
  
  
      }
  
  
      @Override
      protected void onListItemClick(ListView l, View v, int position, long id) {
          // TODO Auto-generated method stub
          super.onListItemClick(l, v, position, id);
  
  
          startActivity(new Intent(CustomListView.this, next.class));
      }
  
  
      public static class EfficientAdapter extends BaseAdapter implements Filterable {
          private LayoutInflater mInflater;
          private Bitmap mIcon1;
          private Context context;
  
          public EfficientAdapter(Context context) {
              // Cache the LayoutInflate to avoid asking for a new one each time.
              mInflater = LayoutInflater.from(context);
              this.context = context;
          }
  
          public View getView(final int position, View convertView, ViewGroup parent) {
  
              ViewHolder holder;
  
  
              if (convertView == null) {
                  convertView = mInflater.inflate(R.layout.adaptor_content, null);
  
  
                  convertView.setOnClickListener(new OnClickListener() {
                      private int pos = position;
                      @Override
                      public void onClick(View v) {
  
  
                      }
                  });
  
  
  
              convertView.setTag(holder);
              }else{
              // Get the ViewHolder back to get fast access to the TextView
              // and the ImageView.
              holder = (ViewHolder) convertView.getTag();
              }
  
  
              return convertView;
          }
  
          ...
      }
  }
  </code></pre>
  
  <p>I tried also adding the next code inside of onCreate method from CustomListView class but it doesn't work either</p>
  
  <pre><code>ListView lv = getListView();
  
  // listening to single list item on click
  lv.setOnItemClickListener(new OnItemClickListener() {
    public void onItemClick(AdapterView&lt;?&gt; parent, View view,
        int position, long id) {
  
          startActivity(new Intent(CustomListView.this, next.class));
  
    }
  });
  </code></pre>
