    <p>In my application, i have a layout which displays bus-stop details in the header of ListActivity while displays all available arrival predictions as a list. List header contains two buttons, first for saving bus-stop to database and second for refreshing the activity. But OnClickListner() is not working. I have tested my code without onClickListner() and it works fine.<br> Remember! in my code, buttons are part of fixed list header I have tried the suggestion already discussed here but those doesn't worked for me. Help me Please... My code is as follows: </p> <pre><code>public class MainBusStopByIdActivity extends ListActivity implements OnClickListener{ private final String TAG = getClass().getSimpleName(); ReadingBusStopByIdData readingData = new ReadingBusStopByIdData(); LinkedList&lt;BusStop&gt; stopList = new LinkedList&lt;BusStop&gt;(); LinkedList&lt;Predictions&gt; predictionsList = new LinkedList&lt;Predictions&gt;(); private AdapterForBusStopById mAdapter; String userInput; Button saveButton; Button refreshButton; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); // Initialising buttons saveButton = (Button) findViewById(R.id.save_button); refreshButton = (Button) findViewById(R.id.refresh_button); // Creating new adapter instance mAdapter = new AdapterForBusStopById(); // Retrieving data (user Input) sent from previous page Intent newIntent = getIntent(); userInput = newIntent.getStringExtra("input"); // Retrieving data on background thread new loadBusStopDetails().execute(userInput); new loadBusPredictions().execute(userInput); // Setting up onClickListner() for both buttons refreshButton.setOnClickListener(this); saveButton.setOnClickListener(this); } @Override public void onClick(View v) { // TODO Auto-generated method stub switch (v.getId()) { case R.id.save_button: boolean didItWork = true; try { if (stopList.size() != 0) { String stopId = null; String stopName = null; for (BusStop stop : stopList) { stopId = stop.getStopId(); stopName = stop.getStopName().toString(); } Toast.makeText(MainBusStopByIdActivity.this, stopId + "\n" + stopName, Toast.LENGTH_LONG).show(); DatabaseAccess entry = new DatabaseAccess( MainBusStopByIdActivity.this); entry.open(); entry.createEntry(stopId, stopName); entry.close(); } else { Toast.makeText(MainBusStopByIdActivity.this, "No Bus-stop Information Found!!!", Toast.LENGTH_LONG).show(); } } catch (Exception e) { didItWork = false; String error = e.toString(); Dialog d = new Dialog(this); d.setTitle("Error!!!"); TextView tv = new TextView(this); tv.setText(error); d.setContentView(tv); d.show(); } finally { if (didItWork) { Dialog d = new Dialog(this); d.setTitle("Entry to Favourites"); TextView tv = new TextView(this); tv.setText("Scuccessfully Added Bus-Stop to Favourites..."); d.setContentView(tv); d.show(); } } break; case R.id.refresh_button: break; } } // Adapter Class private class AdapterForBusStopById extends BaseAdapter { private static final int TYPE_PREDICTION = 0; private static final int TYPE_BUSSTOP_HEADER = 1; private ArrayList&lt;String&gt; mData = new ArrayList&lt;String&gt;(); private LayoutInflater mInflater; private TreeSet&lt;Integer&gt; mSeparatorsSet = new TreeSet&lt;Integer&gt;(); public AdapterForBusStopById() { mInflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE); } public void addItem(final String item) { mData.add(item); notifyDataSetChanged(); } public void addSeparatorItem(final String item) { mData.add(item); // save separator position mSeparatorsSet.add(mData.size() - 1); notifyDataSetChanged(); } @Override public int getItemViewType(int position) { return mSeparatorsSet.contains(position) ?

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
