HI,

I need to start an activity when we click on an item in list view. Also the items in listview must be fetched from servlet when the application is launched.

Take a look at the Android Dev Guide for launching an activity:
http://developer.android.com/guide/topi ... AnActivity

below is also a snippets for your reference,

Code: Select all

listview1 = (ListView) findViewById(R.id.listview1);
        ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(this, R.array.items, android.R.layout.simple_list_item_1);
        adapter.setDropDownViewResource(android.R.layout.simple_list_item_1);
        listview1.setAdapter(adapter);
       
        listview1.setOnItemClickListener(new AdapterView.OnItemClickListener() {
       
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
        if(position == 1) {
        Intent intent = new Intent(getApplicationContext(), Activity2.class);
        startActivity(intent);
        }
        }
});


Hope this could help you
