Question

I am doing a project that currently requires a list and when a particular item from the list is clicked another list activity appears. Is there any solution as to how to move from one listview activity to another. I am currently using http://www.androidhive.info/2012/02/android-custom-listview-with-image-and-text/ as a reference for my ListView.

Answer 1

One solution would be:

Create the second ListView activity and implement the first ListActivity with a OnItemClickListener that opens the second ListViewActivity by using an regular Intent.

    listView = (ListView) findViewById(R.id.mylistview);
        listView.setOnItemClickListener(new OnItemClickListener() {

            @Override
            public void onItemClick(AdapterView<?> arg0, View v, int position,
                    long arg3) {

                Intent intent = new Intent(FirstListActivity.this, SecondListActivity.class);
                Bundle bundle = new Bundle();
                bundle.putString("pos", position);
                intent.putExtras(bundle);
                startActivity(intent);
            }
        });

UPDATE:

I have wrote an simple example list application. You may use it for insperation. The code that could open the Second list activity is included, but commented out. If you get this example to run, you are getting closer. Then you can try comment out the Intent code.

public class MainActivity extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        // Find the ListView resource.   
        ListView mainListView = (ListView) findViewById( R.id.my_list );  

        // Set the Adapter as the ListView's adapter.  
        mainListView.setAdapter( new BaseAdapter(){

            // Create and populate a List of planet names.  
            String[] planets = new String[] {"Mercury", "Venus", "Earth", "Mars", "Jupiter", "Saturn", "Uranus", "Neptune" };    

            @Override
            public int getCount() {
                return planets.length;
            }

            @Override
            public Object getItem(int pos) {
                return planets[pos-1];
            }

            @Override
            public long getItemId(int pos) {
                return 0;
            }

            @Override
            public View getView(int pos, View view, ViewGroup viewgroup) {
                if(view == null){
                    /**

                    view = View.inflate(getApplicationContext(), R.layout.row, null);
                }
                return view;

        });        

        mainListView.setOnItemSelectedListener(new OnItemSelectedListener() {

            @Override

                startActivity(intent);
                */
            }

            @Override
