Question

This code basically fetches data from database and display it in a list along with a searchbox which helps in filtering out specific values from list.

Please check this snapshot!

But the problem is DataAttach.java is extended from Activity which doesn’t support onListItemClick().

If I want to include onListItemClick(),
I must extend the class from ListActivity instead of Activity.

Here comes the problem.
If I extend the class from ListActivity, I can’t include the searchbox in my view.

I’m stuck into deadlock, any suggestions appreciated. Thanks.

DataAttach.java(snippet):

                    symbolarr = dbM.getSymbol();

                    if (symbolarr != null) {
                        list1 = new String[symbolarr.length];

                        for (int i = 0; i < symbolarr.length; i++) {
                            list1[i] = symbolarr[i];
                        }
                    }

                    // ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
                    // android.R.layout.simple_list_item_1, symbolarr);
                    // setListAdapter(adapter);

                    lv.setAdapter(new ArrayAdapter<String>(this,
                            android.R.layout.simple_list_item_1, symbolarr));

DbManager.java(snippet)

            public String[] getSymbol() {
                Cursor cur;
                try {
                    cur = mDb.rawQuery("select symbol,company_name from scrip", null);
                } catch (SQLiteException e) {
                    throw new Error(" *** ERROR in cursor *** " + e.getMessage());
                }

                String[] b1 = new String[1326];
                int x = 0;
                if (cur.moveToFirst()) {
                    do {
                        b1[x] = cur.getString(cur.getColumnIndex("symbol"));
                        x++;
                    } while (cur.moveToNext());
                }
                cur.close();
                return b1;
            }

You can actually go either way:

1. Define a ListActivity with custom layout: http://developer.android.com/reference/android/app/ListActivity.html Note that you MUST set id like this @android:id/list.

2. Without ListActivity: use setOnItemClickListener(AdapterView.OnItemClickListener listener) on your ListView.
