I am trying to put a listview within an activity, then retrieve data from my sqlite database. Then, user can check/uncheck multiple option from that listview that has checkbox included that shows the name of customers.. When the checkbox is checked, i wish to perform function such as add expenses to particular customer in a table in sqlite database that is checked by user. The problem is, i created the listView with checkbox in every row, but i got stucked because i don't know how to perform function on it. Can anyone guide me here? Or giving me idea how to do it? Thanks.
Here is my code with the listView:
public class AddExpense extends ListActivity implements OnClickListener{
EditText expenseName;
Spinner expenseType;
EditText expensePrice;
EditText expenseQuantity;
EventController controller = new EventController(this);
Button btnadd;
ListView lv;
@Override
public void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.addexpense);
expenseName = (EditText)findViewById(R.id.expenseName);
expenseType = (Spinner)findViewById(R.id.expenseType);
// Create an ArrayAdapter using the string array and a default spinner layout
ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(this,
R.array.type, android.R.layout.simple_spinner_item);
// Specify the layout to use when the list of choices appears
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
// Apply the adapter to the spinner
expenseType.setAdapter(adapter);
expensePrice = (EditText)findViewById(R.id.expensePrice);
expenseQuantity = (EditText)findViewById(R.id.expenseQuantity);
btnadd = (Button)findViewById(R.id.btnaddexp);
btnadd.setOnClickListener(this);
HashMap<String, String> queryValues = new HashMap<String, String>();
Intent objIntent = getIntent();
String eventId = objIntent.getStringExtra("eventId");
queryValues.put("eventId", eventId);
//Create Listview that retrieve all the customer data in that event
ArrayList<HashMap<String, String>> friendList = controller
.getAllFriends(queryValues);
if (friendList.size() != 0) {
lv = getListView();
}
SimpleAdapter adapter1 = new SimpleAdapter(AddExpense.this,
friendList, R.layout.view_expenses_participant_entry, new String[] {
"friendId", "friendName" },
new int[] { R.id.friendId, R.id.friendName});
adapter.notifyDataSetChanged();
setListAdapter(adapter1);
}
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
HashMap<String, String> queryValues = new HashMap<String, String>();
Intent objIntent = getIntent();
String eventId = objIntent.getStringExtra("eventId");
queryValues.put("eventId", eventId);
queryValues.put("expenseName", expenseName.getText().toString());
queryValues.put("expenseType", expenseType.getSelectedItem().toString());
queryValues.put("expensePrice", expensePrice.getText().toString());
queryValues.put("expenseQuantity", expenseQuantity.getText().toString());
controller.insertExpense(queryValues);
this.callHomeActivity(v);
finish();
}
public void callHomeActivity(View view) {
super.onResume();
}
}
This is the xml file of every single row :
<CheckBox
android:id="@+id/list_checkbox"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:checked="false" >
</CheckBox>
<TextView
android:id="@+id/friendId"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:visibility="gone" />
<TextView
android:id="@+id/friendName"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="5dp"
android:paddingLeft="6dip"
android:paddingTop="6dip"
android:textColor="#A4C739"
android:textSize="17sp"
android:textStyle="bold" />
</LinearLayout>
