How do i setup a onListItemClick listener so that the i can return only the value from R.id.number from the adapter that ive setup below. I will later pass the value i obtain to another activity.Please Help
sd=new SimpleAdapter(MainActivity.this,alist,R.layout.item_list,new String[]{"No","Name"},new int[]{R.id.number,R.id.item_name});

How do I enable click on listview?

I'm currently working on a code which is written by someone else in my office. I need to enable selection of items in the listview. I know I have to use setOnClickListener. Can someone guide me through this? I've written:
Edit:
listview.setOnClickListener( (View.OnClickListener) this );
Now what do I do?
I need to select an int value and pass it on to another function, which is used to retrieve a certain set of values from a db.
listviewName.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
//variable position will give you the required element/object from the array list.
}
});
YourListView.setOnItemClickListener(new ListView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> a, View v, int pos, long l) {
try {
Toast.makeText(this,"Position is===>>"+pos , Toast.LENGTH_LONG).show();
}
catch(Exception e) {
System.out.println("Nay, cannot get the selected index");
}
}
});
Hope it helps.
ListView list = (ListView)findViewById(R.id.quoteX2);
list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id)
{
// - -- - -Your Code here
}
});
Hope it helps!

How do I add Click Listener to ListView?

I have a List View which is populated with countries I want to be able to click a an item and have it go to another activity in which i play an audio.
my list View:
public class MainActivity extends ListActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
setListAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_selectable_list_item,getResources()
.getStringArray(R.array.countries)));
}
}
How do I go about adding a onClick just like how you would make one for a button??
ListView listView = getListView(); // hear bind your listview
setListAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_selectable_list_item,getResources().getStringArray(R.array.countries)));
listView.setAdapter(ListAdapter);
listView.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> listView, View itemView, int itemPosition, long itemId)
{
}
});
}
}
Either use getListView() to access built in list view, and operate on that:
getListView().setOnItemClickListener();
Or, override onListItemClicked() in ListActivity:
#Override
protected void onListItemClick(ListView l, View v, int position, long id) {
super.onListItemClick(l, v, position, id);
//--do stuff--
}
override onItemClick() method
#Override
public void onItemClick(AdapterView<?> arg0, View view, int arg2,
long arg3) {
// TODO Auto-generated method stub
Intent intent = new Intent(getApplicationContext(), Activity2.class);
startActivity(intent);
}
Since your activity extends ListActivity
ListView lv = getListView();
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> listView, View itemView, int itemPosition, long itemId)
{
Intent launchActivity = new Intent(FirstActivity.this, SecondActivity.class);
startActivity(launchActivity);
}
});
U can use context.getlistview() to get the listview. and add setOnItemClickListener to the listview like this.
context.getlistview().setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
//Do whatever you want here
}
});
To make it handy just implement OnItemClickListener to your class
Add this in onCreate
ListView listView = getListView();
listView.setOnItemClickListener(this);
then override onItemClick like this
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int position, long id){
// your code
}
You have to use the setOnItemClickListener method.
Here is the code
listview.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
// TODO Auto-generated method stub
// do your code here
}
});

Set onItemClick listener for ListView in Android

I'm trying to set an OnItemClickListener for my ListView in Android, but i can't get it to work.
This is what i have so far:
public class MenuFragment extends SherlockFragment
{
ArrayList<Item> items = new ArrayList<Item>();
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState)
{
ListView list = (ListView)view.findViewById(R.id.list_mainmenu);
// some code here where i add items to an ArrayList...
// Then i add the ArrayList to an EntryAdapter
EntryAdapter adapter = new EntryAdapter(this.getActivity().getBaseContext(), items);
list.setAdapter(adapter);
list.setClickable(true);
list.setOnItemClickListener(AdapterView.OnItemClickListener()) {
// ...
}
}
But this gives me an error on OnItemClickListener():
The method OnItemClickListener() is undefined for the type AdapterView.
So my qyestion is, how can i set an OnItemClickListener on my ListView??
check this code
listView.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> 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();
}
});
make sure you have imported correct packages:
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
try this
list.setOnItemClickListener(new AdapterView.OnItemClickListener()) {
// ...
}
You should implement a customAdapter for having more control on your listView, Here is the link after visiting this you should be able to do what is required. Or you can have this code to quickly do what you need.
listView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View view, int arg2,long itemID) {
}
});
Try this:
list.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> a, View v, int position, long id) {
// ...
}
});
try this one
listView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
}
});

how to add onItemClick method in ListView?

I want to add onItemClick method in listview of my app. I created a listview by using http://jsharkey.org/blog/2008/08/18/separating-lists-with-headers-in-android-09/
but unable add click method.
please suggest solution.
Use this:
yourList.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> arg0, View view, int position, long id) {
}
});
I think you hava to use following method.
list.setAdapter(new EfficientAdapter(getParent()));
list.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0,
View arg1, int arg2, long arg3) {
}
});
Before creating acticity make sure it is ListActicity. After that pass the selected value (item) to the below method.
public void onListItemClick(ListView parent, View v, int position,
long id) {
selection.setText(items.get(position).toString());
}
Set an OnItemClickListener to your ListView.
Use the following code:
list.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> arg0, View view, int position, long id) {
// Put your custom code here
}
});
public void onListItemClick(ListView parent, View v, int arg1,
long id) {
selection.setText(items.get(arg1).toString());
}

create Listview without using listactivity.only use activty

I know how can implement listview without using listactivity.But i dont know how get the clicked item from the listview.Please anyone tell me how listen the clicked item from the listview without using listactivity.
Please Follow this Link. Here you can find simple Listview example using Activity.
Using listview.setOnItemClickListener you can get Click on Listview.
listView.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> arg0, View view, int position,
long id)
{
}
You can implements OnItemClickListener and can write the method like below or just simply use eclipse to implement unimplemented method
public void onItemClick(AdapterView<?> arg0, View view, int position,
long id) {
}
First you have to make instance of list view Clickable like
lv.setClickable(true);
then
use following
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> arg0, View view, int position,
long id)
{
}
use ListView.
Then with the listview object invoke
lv.setOnItemClickListener(new OnItemClickListener(){
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
//do your stuff
}
}
for click on listview in activiyt try this code...
ListView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View arg1,
int arg2, long arg3) {
//write you action here
}
});
