I have added leadbolt ad(entry ad). The advertising works correctly but listview.click doesn't work when I close ad from close sign. (Listview.click does not do anything, It works when I remove AdController)
public class SoundList extends ListActivity {
int [] soundfile;
MediaPlayer mediaPlayer;
private AdController myController;
final Activity act = this;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
myController = new AdController(act, "111111111");
myController.loadAd();
soundfile= new int[] {R.raw.sound1,R.raw.sound2.....};
String[] sounds= getResources().getStringArray(R.array.sounds);
// Binding Array to ListAdapter
this.setListAdapter(new ArrayAdapter<String>(this, R.layout.list_item, R.id.label, sounds));
ListView lv = getListView();
lv.setDescendantFocusability(ListView.FOCUS_BLOCK_DESCENDANTS);
// listening to single list item on click
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
Intent intent = new Intent(getApplicationContext(), SingleListItem.class);
intent.putExtra("position", position);
startActivity(intent);
}
});
}
Having a focusable item in a row of a ListView causes the OnItemClickListener NOT to be invoked.
To fix this issue add following code to row view.
XML:
android:descendantFocusability="blocksDescendants"
Java:
listItem.setDescendantFocusability(FOCUS_BLOCK_DESCENDANTS);

I have a ListView with several items and every item has it own Activity class to show details. How can I switch to an appropriate activity when user selects and item in this ListView?
My current code is following:
ListView listView;
ArrayAdapter<String> adapter;
String[] hotel = {"one room", "double room", "suit", "vip"};
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
listView = (ListView) findViewById(R.id.listView);
adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, hotel);
listView.setAdapter(adapter);
}
Add setOnItemClickListener to your listView in onCreate under listView.setAdapter(adapter); :
listView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
if(position == 0){
Intent intent = new Intent(MainActivity.this, OneRoomActivity.class);
startActivity(intent);
}
else if(position == 1){
Intent intent = new Intent(MainActivity.this, DoubleRoomActivity.class);
startActivity(intent);
}
//Do as above for rest of the list items
}
});
Hope this helps.
How to implement onItemClickListener on each item in the ListView to go to another activity / to a new class?
public class MainActivity extends Activity{
ListView list;
String[] itemname ={
"Resturants",
"Coffee Shops",
"Hotels",
"Gas Stations",
"Hospitals",
"Airports",
"ATM",
"Cinemmas",
"Phamacies"
};
Integer[] imgid={
R.drawable.restaurantz,
R.drawable.coffeeshop,
R.drawable.hotel,
R.drawable.gaspump,
R.drawable.hospitalblue,
R.drawable.airporticon,
R.drawable.atm,
R.drawable.cinemma,
R.drawable.hospitalblue,
};
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.content_main);
CustomListAdapter adapter = new CustomListAdapter(this, itemname, imgid);
list = (ListView) findViewById(R.id.list);
list.setAdapter(adapter);
list.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
}
});
}
}
inside onItemClick:
startActivity(new Intent(MainActivity.this, NewActivity.class));
if you need to differenciate the clicked item, you can use the position parameter, for example:
if (position == 0)
// do something
else
// do something else
My MainActivity, which extends ActionBarActivity, has a ListView, which I want to reload using notifyDataSetChanged(), but I do not know how to do this.
My code so far:
public class MainActivity extends ActionBarActivity {
private JournalEntryDataSource datasource;
private ListView listView = null;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
datasource = new JournalEntryDataSource(this);
datasource.open();
listView = (ListView) findViewById(R.id.list);
List<JournalEntry> values = datasource.getAllJournalEntries();
listView.setAdapter(new ArrayAdapter<JournalEntry>(this, R.layout.list_item, R.id.lugares, values));
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView<?> arg0, View v, int position, long id) {
Log.i("app", "Deleting item number " + position);
datasource.deleteJournalEntry((JournalEntry) listView.getAdapter().getItem(position));
//I would like to do this here:
//ArrayAdapter<JournalEntry> adapter = (ArrayAdapter<JournalEntry>) getListAdapter();
//adapter.notifyDataSetChanged();
}
});
}
But I get an error when calling adapter.notifyDatasetChanged()...
Any tips? I've been looking at similar questions and no luck so far...
--------EDITED CODE---------
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
datasource = new JournalEntryDataSource(this);
datasource.open();
listView = (ListView) findViewById(R.id.list);
values = datasource.getAllJournalEntries();
listView.setAdapter(new ArrayAdapter<JournalEntry>(this, R.layout.list_item, R.id.lugares, values));
ArrayAdapter<JournalEntry> adapter = (ArrayAdapter<JournalEntry>) getListAdapter();
// use the SimpleCursorAdapter to show the
// elements in a ListView
listView.setAdapter(new ArrayAdapter<JournalEntry>(this, R.layout.list_item, R.id.lugares, values));
listView.setLongClickable(true);
listView.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {
public boolean onItemLongClick(AdapterView<?> parent, View v, int position, long id) {
Log.i("hola","borrando la posición "+position);
JournalEntry removeMe = (JournalEntry)listView.getAdapter().getItem(position);
values.remove(removeMe);
datasource.deleteJournalEntry(removeMe);
//adapter.notifyDataSetChanged();
reloadMe();
return true;
}
});
}
public void reloadMe(){
//need to do this better... but meh.
Intent intent = new Intent(this, MainActivity.class);
this.startActivity(intent);
}
protected ListView getListView() {
if (listView == null) {
listView = (ListView) findViewById(android.R.id.list);
}
return listView;
}
protected void setListAdapter(ListAdapter adapter) {
getListView().setAdapter(adapter);
}
protected ListAdapter getListAdapter() {
ListAdapter adapter = getListView().getAdapter();
if (adapter instanceof HeaderViewListAdapter) {
return ((HeaderViewListAdapter)adapter).getWrappedAdapter();
} else {
return adapter;
}
}
}
Updated Answer for updated code
instead of creating the same activity again, you should choose to set another new adapter object with the new values object.
public void reloadMe(){
//need to do this better... but meh.
//Intent intent = new Intent(this, MainActivity.class);
//this.startActivity(intent);
listView.setAdapter(new ArrayAdapter<JournalEntry>(this, R.layout.list_item, R.id.lugares, values));
}
Perhaps, you are deleting from
datasource.deleteJournalEntry((JournalEntry) listView.getAdapter().getItem(position));
But you did not set "datasource" as the data source of the adapter. If you look carefully you did set the "values" list object-
listView.setAdapter(new ArrayAdapter<JournalEntry>(this, R.layout.list_item, R.id.lugares, values));
Perhaps you may need to also remove from the values list also.
I am not able get onItemCickListener to work. All I am doing is opening up a fragment using intents. Please do let me know if I am doing anything fishy here ?
public class MyListFragment extends ListFragment {
private ArrayList<String> myList = null;
private ArrayAdapter<String> myAdapter;
#Override
public void onActivityCreated(Bundle savedInstanceState){
Log.d("Example:", "In Fragement Calss");
super.onActivityCreated(savedInstanceState);
Resources myResources = getResources();
myList = new ArrayList<String>(Arrays.asList(myResources.getStringArray(R.array.myExamArray)));
myAdapter = new ArrayAdapter<String>(getActivity(),android.R.layout.simple_list_item_1,myList);
setListAdapter(myAdapter);
ListView lv = (ListView) getActivity().findViewById(R.id.listView);
lv.setOnItemClickListener(new OnItemClickListener(){
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
Intent myIntent = new Intent(view.getContext(), DetailsFragment.class);
startActivity(myIntent);
}
});
}
}
Note that the ListView blocks clicks of an item that contains at least one focusable
descendant but it doesn’t make the content focus-reachable calling
setItemsCanFocus(true). One workaround is by disabling focusability of descendants, using
android:descendantFocusability="blocksDescendants"
in the layout defining your list item. (First learned of this myself from http://cyrilmottier.com/2011/11/23/listview-tips-tricks-4-add-several-clickable-areas/, but a few other SO posts also point this out.) Does your layout contain buttons? If so, you'd fall into this case.
I don't see where you are inflating a specific XML for this Fragment... but it is possible you are referencing the wrong ListView.
Regardless you should use the existing onListItemClick method:
public class MyListFragment extends ListFragment {
private ArrayList<String> myList = null;
private ArrayAdapter<String> myAdapter;
#Override
public void onActivityCreated(Bundle savedInstanceState){
// Remove the OnItemClickListener, but keep everything else
}
#Override
public void onListItemClick (ListView l, View v, int position, long id) {
Intent myIntent = new Intent(this, DetailsFragment.class);
startActivity(myIntent);
}
}
I've searched around for a while now to try to find a solution to this problem, but none of them have worked for me. I have a tab setup which displays tab activities. I'm trying to use a OnClickListener in ListView to catch click events in a list, but it doesn't work. Thanks in advance for helping!
