    <p>I have a ListActivity:</p> <pre><code>public class MedTime extends ListActivity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.no_elements_l); String[] receipts = getResources().getStringArray(R.array.receipts_array); setListAdapter(new ArrayAdapter&lt;String&gt;(this, R.layout.list_item, receipts)); ListView lv = getListView(); lv.setTextFilterEnabled(true); lv.setOnItemClickListener(new OnItemClickListener() { public void onItemClick(AdapterView&lt;?&gt; parent, View view, int position, long id) { // When clicked, show a toast with the TextView text Toast.makeText(getApplicationContext(), ((TextView) view).getText(), Toast.LENGTH_SHORT).show(); } </code></pre> <p>I'd like: when user clicks on list item, new activity named "view" launches. In addition, i need to say to this "view" activity which element from list called it. For example, if I click to 3rd element of list, activity "view" must be started and show me text = 3rd element of string array. The code fragment of "view" is here (value of i in last line must be sent by main activity to this, in my example i=3):</p> <pre><code>String[] receipts = getResources().getStringArray(R.array.receipts_array); TextView tv = new TextView(this); tv.setText(receipts[i]); </code></pre> <p>Please, tell me how to 1) launch "view" activity when user click a list item; 2) how to launch in this case "view" with the parameter that describes number of item selected?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
