I'am trying to click a button on my list view to update that row first of all I tried to click on the item in the list view to show toast.
I did setOnItemClickListener of the ListView
public class Medlistview extends Activity{
DB db = new DB(this);
ImageButton updateimagebutton = (ImageButton)findViewById(R.id.editbuttonimage);
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.medlistview);
populatemedlistview();
}
public void populatemedlistview(){
Cursor cursor = db.getMEDINF();
String[] medinfo = new String[]{
DB.col1,DB.col2,DB.col3,DB.col4,DB.rowID
};
int[] mappingmed = new int[]{
R.id.MEDid,R.id.MedName,R.id.Medpurpose,R.id.medNotaplet,R.id.ROWID
};
SimpleCursorAdapter medcursoradapter = new SimpleCursorAdapter(this,R.layout.medlistviewxml,cursor,medinfo,mappingmed);
ListView medlistview = (ListView)findViewById(R.id.listViewmed);
medlistview.setAdapter(medcursoradapter);
medlistview.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Toast.makeText(Medlistview.this,"clicked",Toast.LENGTH_LONG).show();
}
});
}
}
I made sure that my list view is clickable and focusable but still not working
One more thing I already define image button on layout item not on ListVew layout every time I run the app, is crashing and showing that null reference message in the log-cat do I need to define the button also on the ListView layout.
Caused by: java.lang.NullPointerException: Attempt to invoke virtual method 'android.view.View android.view.Window.findViewById(int)' on a null object reference

Thanks in Advance.
Implement View.OnClickListener() to your ImageButton in getView() method in your adapter, not in Medlistview activity. And use callback or eventBus to work with click action in your activity.
#Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if (convertView == null) {
holder = new ViewHolder();
convertView = inflater.inflate(R.layout.recycler_view_item, parent, false);
holder.tvName = (TextView) convertView.findViewById(R.id.tvName);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
holder.tvName.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// Button was clicked
}
});
return convertView;
}
Set
android:focusable="false"
android:focusableInTouchMode="false"
for all UIs controls in your custom layout file.
use android:descendantFocusability="blocksDescendants" inside listview,
check out this answere: can't click on listview row with imagebutton
Set the parent layout of the item
android:descendantFocusability="blocksDescendants"
and set
android:clickable="false"
android:focusable="false">
on all your widgets.

I checked all the previous questions regarding this issue , but none of them are helpfull to me .
My listview is not responding , i tried changing this
list.setOnItemClickListener(new ContactsListItemClickListener(this));
to
list.setOnItemClickListener(this);
by making my PrioritiseContacts activity just imeplement OnItemClickListener , but then too its not working .
The activity is successfully running , but i am unable to listen for listclick events.
How to correct this?
Here is my class :
public class PrioritiseContacts extends Activity implements OnClickListener {
private ListView list;
// list of contacts with name
private List<Contacts> contactsList;
private Controller controll;
private ContactListAdapters adapter;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.select_contacts);
controll = new Controller();
contactsList = controll.fetchContacts(this);
// call the adapter to set the list view layout
adapter = new ContactListAdapters(contactsList, this);
list = (ListView) findViewById(R.id.lv_contacts);
// set the adapter to list
list.setAdapter(adapter);
list.setOnItemClickListener(new ContactsListItemClickListener(this));
// inflate the list of contact
}
#Override
public void onClick(View arg0) {
Toast.makeText(this, "clicked", 1000).show();
}
class ContactsListItemClickListener implements OnItemClickListener {
private Context c;
public ContactsListItemClickListener(
PrioritiseContacts prioritiseContacts) {
this.c = prioritiseContacts;
}
#Override
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
Toast.makeText(c, "Clicked", 1500).show();
System.out.print("clicked");
}
}
}
My select_contacts xml :

If any row item of list contains focusable or clickable view then OnItemClickListener won't work such as for checkbox or button etc in the row item.There are two solution:
1. row item must be having param like android:descendantFocusability="blocksDescendants"
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:baselineAligned="false"
android:descendantFocusability="blocksDescendants"
android:gravity="center_vertical" >
// your other widgets here
</LinearLayout>
2. Set given two attributes to false
like
android:focusable="false"
android:focusableInTouchMode="false"
For example if there is any checkbox or button or image in the row item then
<CheckBox
android:id="#+id/fav_check_box"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:focusable="false" />

I'm stumped. This one IS simple and I'm missing something simple but I'm just not getting anywhere.
I have a ListView that contains pretty simple items - TextView's that contain text of the form "N. name", where N is the position in the list and name is the name of the associated objects. I've created a ListAdapter that presents that information into the ListView.
The presentation stuff seems to work fine. It's the part where when I tap on a row that's not working. I just don't get a notification. If I set a onClickListener on the item (when it's generated in the Adapter) I do get a notification, but it's convoluted to make that work the way I'd like it to. I've tried a bunch of stuff - changing descendent focusability, enabling, disabling, setting itemsCanFocus to false, ... - but no luck on any of them.
I've included relevant code for configuring the view and the elements in the ListView.
In particular, what I'm trying to do is get that OnItemClickLister.onItemClick() to get invoked when I tap on a row. Any thoughts on what I'm doing wrong?

in the textview of your inflator layout just add:
android:focusable="false"
android:focusableInTouchMode="false"
and in parent layout of your inflator i.e in relative layout of inflator add:
android:descendantFocusability="blocksDescendants"
remove :
android:descendantFocusability="beforeDescendants"
from your listview. and set height of your listview to match_parent will solve your issue.
remove following attributes from your ListView:
android:choiceMode="none"
android:clickable="true"
android:descendantFocusability="beforeDescendants"
also
android:layout_width="wrap_content"
android:layout_height="wrap_content"
makes no sense in this context (especially height)

and i'm setting an onItemClickedListener:

//create a new event list
picoEventsList = new ArrayList<PicoEvent>();
//create new gridview arrayadapter
arrayAdapter = new EventDetailsArrayAdapter(getActivity(), picoEventsList);
//set grid's view empty view
View emptyView = LayoutInflater.from(getActivity()).inflate(R.layout.fragment_events_empty_view, null);
gridView.setEmptyView(emptyView);
gridView.setOnItemClickListener(this);
gridView.setAdapter(arrayAdapter);
}
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
//get clicked event
PicoEvent event = arrayAdapter.getItem(arg2);
//create new event details fragment
EventDetailsFragment eventDetailsFragment = new EventDetailsFragment();
//add the event to fragment's arguments
eventDetailsFragment.setArguments(PicoEventCreator.createBundle(event));
//show the event details fragment
getMainActivity().showFragment(null, eventDetailsFragment, true, true);
}
but the onItemClick() method doesn't get fired..
I've checked and non of my views in my layout has clickable="true" setted...
Any ideas ?
Hey guyz finally got a solution...
what we were doing is directly accessing the Layout inside the GridView, so the onItemClickListener finds it confusing to access the item.
So the solution is to apply the onClickListener inside the Adapter (i.e. normally ArrayAdapter)
so what i m trying to say is:
public View getView(int position, View convertView, ViewGroup parent) {
//Here row is a view and we can set OnClickListener on this
final View row;
ViewHolder holder = null;
if (convertView == null) {
LayoutInflater inflater = ((Activity) context).getLayoutInflater();
//Here we inflate the layout to view (linear in my case)
row = inflater.inflate(layoutResourceId, parent, false);
holder = new ViewHolder();
holder.imageTitle = (TextView) row.findViewById(R.id.text);
holder.image = (ImageView) row.findViewById(R.id.image);
row.setTag(holder);
} else {
row = convertView;
holder = (ViewHolder) row.getTag();
}
ImageItem item = data.get(position);
holder.imageTitle.setText(item.getTitle());
holder.image.setImageBitmap(item.getImage());
//Now get the id or whatever needed
row.setId(position);
// Now set the onClickListener
row.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Toast.makeText(context, "Clicked" + row.getId() + "!!",
Toast.LENGTH_SHORT).show();
}
});
return row;
}
Ok i found what the problem was
Apparently GridView and HorzonitalScrollView are not such good friends...
probably because the HorzonitalScrollView has onClick funcionality..
The solution i found is to put:
android:descendantFocusability="blocksDescendants"
in my ArrayAdapter root view.
I have used a Custom ListView and I am displaying some data using the same ListView. When I click on the List View item, the onClickListener is not getting called. I am not able to select any list item.

Even scrolling is not working.
I am unable to figure out why is this happening? Am I missing out something?
Any help in resolving this is appreciated.
The following will do the job in your case.
ListView propertylistview = (ListView) findViewById(R.id.listview);
propertylistview.setOnItemClickListener( myListViewClicked ):
OnItemClickListener myListViewClicked = new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Toast.makeText(YourActivity.this, "Clicked at positon = " + position, Toast.LENGTH_SHORT).show();
}
};
Dont forget to remove the following from the CustomAdapter
convertView.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(parent.getContext(), "view clicked: " + ListArray.getName(), Toast.LENGTH_SHORT).show();
}
});
If the touch events are getting intercepted inside the cell layout, in the layout for your custom cell, set
android:descendantFocusability="blocksDescendants" on the top level layout of your cell. For me, it was too much of a pain to add xml attributes to every individual view.
Note that this can also be set in code:
cell.setDescendantFocusability(FOCUS_BLOCK_DESCENDANTS);
I also tried this with a ListView inside a cell, and I had to override onTouchEvent to get it to work:
public class NoTouchListView extends ListView {
#Override
public boolean onTouchEvent(MotionEvent ev) {
return false;
}
}
the simple code that solved my problem, and method view.setOnClickListener be within my custom adapter
view.setFocusable(false)
Check your list row layout once :
layout or any view should not be `android:clickable="true" and
android:focusable="true"
if it is there just delete and run the application again.
Even I was having the same problem, I am having checkbox, did the following to masker itemClickListener work,
Added the following properties to the checkbox,
android:focusable="false"
android:focusableInTouchMode="false"
android:clickable="false"
and ItemClickListner started working.
For detailed example you can go through the link,

Hope it helps Cheers!!
For TextView you should also use
android:textIsSelectable="false"
