How can I set onClickListener on ArrayAdapter?

you can also do like this..

moreListView.setOnItemClickListener(new OnItemClickListener() {            @Override            public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,                    long arg3) {                // TODO Auto-generated method stub                Log.d("############","Items " +  MoreItems[arg2] );            }        });

There are two option to handle click event for each row.

1) If your class extends ListActivity, you can override following method.

@Overrideprotected void onListItemClick(ListView l, View v, int position, long id) {  super.onListItemClick(l, v, position, id);  //do something here using the position in the array}

2) Handle click event of row in getView() method

row.setOnClickListener(new OnClickListener() {    @Override    public void onClick(View v) {    }});

For example:

 ListView lv = getListView();        lv.setAdapter(listAdapter);         lv.setOnItemClickListener(new OnItemClickListener() {            public void onItemClick(AdapterView<?> parent, View view,int position, long id) {                Intent i = new Intent(More.this, NextActvity.class);               //If you wanna send any data to nextActicity.class you can use                 i.putExtra(String key, value.get(position));            startActivity(i);            }          });
