OnClick Listner of images in Grid View Android

I have a Grid View that have 4 images .So i want to identify which image has been clicked so that corresponding to that i can start a new activity .
So please help me how can i get this
I have tried this
dataView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
}
});

getView can be used for this purpose.for this in getView find View and apply onClicklistner their.to make all views clickable you need to setFocusable(false) on all focusable views.

I have got the solution
dataView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View v, int arg2,
long arg3) {
// TODO Auto-generated method stub
Toast.makeText(
getApplicationContext(),
links[arg2], Toast.LENGTH_SHORT).show();
}
});

int arg2 in the OnItemClick method specifies the position.Using that you can get the item clicked.

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
}
});

Setting up OnListItemClick Listener

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});
list.setAdapter(sd);

Try this
list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View view, int position, long arg3) {
String number=((TextView)view.findViewById(R.id.number)).getText().toString();
}
});

Check selected item of ListView

I have a ListView and need to check, which item has been clicked.
The way I have it, it only shows my the selected item when I use the scrollwheel of my mouse (when testing it in the Eclipse emulator). When I test it on a real mobile device, it doesn't react at all.
adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, listItems);
listView.setAdapter(adapter);
listView.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
public void onItemSelected(AdapterView<?> arg0, View arg1,
int arg2, long arg3) {
myFunction(listView.getSelectedItem());
}
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
});

Use setOnItemClickListener instead of setOnItemSelectedListener
listView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
//get value for listItems using position
String str =listItems[position];
myFunction(str);
}
});

I think better you need to use on onListItemClick listener
public void onListItemClick(ListView parent, View v, int position, long id)
{
parent.setItemChecked(position, parent.isItemChecked(position));
Toast.makeText(this, "You have selected" + items[position],30).show();
}

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
}
});
