How do I listen to click event on a ListView?
This is what I have now
ListView list = (ListView)findViewById(R.id.ListView01);
...
list.setAdapter(adapter);
When I do the following
list.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
public void onItemSelected(AdapterView parentView, View childView,
int position, long id)
{
setDetail(position);
}
public void onNothingSelected(AdapterView parentView) {
}
});
That doesn't seem to do anything on click.
And all those code live within a class that extends Activity.
This example demonstrates how do I handle the click event in ListView in android. Step 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project. Step 2 − Add the following code to res/layout/activity_main. xml.
One potential way to achieve is it set your ListView to height="wrap_content" If you do that then you can have override onTouchEvent() for your activity to get the events from when the user touches the empty space.
OnItemClickListener() { @Override public void onItemClick(AdapterView<?> parent, View view, int position, long id) { Object listItem = list. getItemAtPosition(position); } }); In the sample code above, the listItem should contain the selected data for the textView .
On your list view, use setOnItemClickListener
Suppose ListView object is lv, do the following-
lv.setClickable(true);
lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int position, long arg3) {
Object o = lv.getItemAtPosition(position);
/* write you handling code like...
String st = "sdcard/";
File f = new File(st+o.toString());
// do whatever u want to do with 'f' File object
*/
}
});
You need to set the inflated view "Clickable" and "able to listen to click events" in your adapter class getView() method.
convertView = mInflater.inflate(R.layout.list_item_text, null);
convertView.setClickable(true);
convertView.setOnClickListener(myClickListener);
and declare the click listener in your ListActivity as follows,
public OnClickListener myClickListener = new OnClickListener() {
public void onClick(View v) {
//code to be written to handle the click event
}
};
This holds true only when you are customizing the Adapter by extending BaseAdapter.

The two answers before mine are correct - you can use OnItemClickListener
.
It's good to note that the difference between OnItemClickListener
and OnItemSelectedListener
, while sounding subtle, is in fact significant, as item selection and focus are related with the touch mode of your AdapterView
.
By default, in touch mode, there is no selection and focus. You can take a look here for further info on the subject.
