 public class MainActivity extends ListActivity {
     private String selectedName = "";
        private String[] nameList;

        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);

            nameList = getResources().getStringArray(R.array.name_list);

            setListAdapter(new ArrayAdapter<String>(this,
                    android.R.layout.simple_list_item_1, nameList));

            registerForContextMenu(getListView());

        }

        public void onCreateContextMenu(ContextMenu menu, View v,
                ContextMenuInfo menuInfo) {
            // Inflate the menu; this adds items to the action bar if it is present.
            getMenuInflater().inflate(R.menu.context_menu, menu);
        }

        public boolean onContextItemSelected(MenuItem item) {

            AdapterContextMenuInfo adapInfo = (AdapterContextMenuInfo) item
                    .getMenuInfo();
            selectedName = nameList[(int) adapInfo.id];

            switch (item.getItemId()) {
            case R.id.view:
                Toast.makeText(MainActivity.this,
                        "You have pressed View Context Menu for " + selectedName,
                        Toast.LENGTH_LONG).show();
