How to set OnItemClickListener on ListView using CustomAdapter

I have displayed the list of student from the database, field that are displayed Student_Roll_no, Student_Name and Student_ID.
Student_Roll_no and Student_Name are display using TextView and Student_ID id is display with checkbox.
Now I want to set the code by which, when I click at the list the checkbox of that particular row should be checked but the listview is not responding to OnItemClickListener function, as there i have make a toast that doesn't appear when i click on the list.
Sry for the bad english

Attendence.php file and the database is hosted on a free hosting web server(Hostinger). you can check the DB output using the
http://painnation.esy.es/attendence.php?date=18022017&course=MCA&year=3
Output Screen
Data from server is fetch in json format.plz comment the code to do check the checkbox by clicking listview.
Thank You

i think you should put android:focusable="false" in item_layout.xml for checkbox, then onItemClickListener respond. for checkbox you need to put variable in DataModel, android make it true or false and change in listview put adapter.notifyDataSetChanged
<CheckBox
android:layout_width="0dp"
android:layout_height="wrap_content"
android:id="#+id/id"
android:layout_weight=".15"
android:focusable="false"
android:textColor="#000000" />

Replace the below
InviteUsersListRow rowUser = new InviteUsersListRow(R.id.profileImage, R.id.imageButtonInviteUser, name, mobile);
with
InviteUsersListRow rowUser = new InviteUsersListRow(R.drawable.camera, R.drawable.add_user_50, name, mobile);
The pic should be from "R.drawable" not from "R.id"
You should actually set an image resource below and not an id
holder.imageView.setImageResource(rowItem.getImageId());
holder.imgStatus.setImageResource(rowItem.getImageStatus());
In the above code you are not setting a drawable item.

ListFragment and Custom Adapter Issue

Two issue with List Fragment: 1. I have a class that extends ListFragments.In the onCreated, I am setting my custom Adapter. The issue is that when the user logs in, the adadpter is null and would not have a value until the user searches for an owner. As a result, it throws an exception when it tries to set up the listadapter and it finds the ArrayAdapter object to be null. I have a custome layout that has a listview and a textview, but I still gets the error. See sample code below. I bold the line of code where the issue happens. Also, I bold few other section where I think it may be important to notice.
I implemented Parcelable in the class "Owner" so that I can pass the object as a ParcelableArray. Even though the object is not null, retrieving it in the OwnerDetail class shows null as if I did not pass it it. I've seen several example, but I am not able to get it right. What am I doing wrong here?
Note: If I were to call the AsyncTask in the OwnerDetail class and set the ListAdapter, it will work fine. The issue with that is that it will display a list of owners as soon as the user is logged in which is not the expected behavior. The behavior that I want is to login first, search for an owner, display the owner, double click on an owner, and finally display a list of cars that the owner owns. I am doing this project, so I can learn how to use ListFraments.

Your code has a lot of problems:
1 Never call lifecycle methods on your own like you do in the OwnerDetail class with super.onActivityCreated(savedInstanceState);
2 Bundle values = getActivity().getIntent().getExtras(); ... values.getParcelableArray("test"); will normally fail because this piece of code will get the activity reference, get the Intent that started the activity and then try to find data passed in under the test key in that Intent. You don't pass such data to the People activity so there will be nothing to be found. You'd normally want to pass a Bundle containing the data at the moment of the creation of the fragment.
3 If you use the fragment in the xml layout you'll not be able to use a Bundle to pass data, instead you either add the fragment manually with transactions and then use a Bundle or you create a setter method in the fragment class and use that. So instead of Bundle data = new Bundle(); data.putParcelableArray("test", myOwners);, which does nothing, get a reference to your fragment and pass the myOwners array through a method.
4 Your AsyncTask will be pretty useless if you use them with .get() because the get() method will wait the AsyncTask to finish, blocking the UI tread as well. Instead you should just start the AsyncTask and then in the onPostExecute() pass the data around.
Here is an example with a simple method which will not change most of your code(which will happen if you manually add the fragments):
// where you start the owner asynctask
if(!searchByName.matches("")) {
OnwerAsyncTask asynTask = new OnwerAsyncTask(People.this);
asynTask.execute("");
}
//...
Then change the OnwerAsyncTask like this:
public class OnwerAsyncTask extends AsyncTask<String, Void, List<Owner>> {
private List<Owner> items = null;
private FragmentActivity mActivity;
public OnwerAsyncTask(FragmentActivity activity) {
mActivity = activity;
}
// doInBackground()...
#Override
protected void onPostExecute(List<Owner> result) {
//I'm assuming that items is the data you want to return, so
// find the OwnerDetail fragment and directly assign the data
OwnerDetail fragment = (OwnerDetail)mActivity.getSupportFragmentManager().findFragmentById(R.id.fOwnerDetail);
fragment.setData(); // to setData you'll pass the data you have in the AsyncTask
// the items list? or you transform that into an array?
}
and in the OwnerDetail fragment:
public class OwnerDetail extends ListFragment {
OwnerAdapter ownerAdapter = null;
public void setData() {
// update the adapter, create a new one etc.
}

onListItemClick is not working for listview?

Hi onListItemClick for listview is not working. Here i am fetching datas from SQLite using AsyncTask and displaying it in a list view. And i wants to do some actions when a list in a listview has clicked. But the click is not happening. I had tried a lot for this. Please help me.

Add below code to your TextView in the XML
android:focusableInTouchMode="false"
android:clickable="false"
android:focusable="false"
and try again.
Another simple solution: add android:descendantFocusability="blocksDescendants" to the root viewgroup.

You should add android:focusable="false" for ListView row items to make ListView Clikable. Because the views in the row of ListView gain the focus so ListView is not focusable. So, in your case you can add android:focusable="false" to the TextViews of your ListView row.

I had the same symptoms, and it drove me crazy for a while. Adding android:focusable="false" for the list items as suggested above fixed the problem for me.
But the real issue was that I had set android:textIsSelectable="true" for my list items (in response to a Warning generated by Eclipse); setting android:textIsSelectable="false" fixed the problem for me, and I did not need the android:focusable="false" option at all.

The workaround I found avoid the
AdapterView.OnItemClickListener mMessageClickedHandler=new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
}
};
on the ListView, but exploit the Adapter constructor that takes a Context as parameter:
myCustomAdapter=new MyCustomAdapter(ActivityName.this,...)
Passing ActivityName.this is possible to cast the Context in the adapter's class as ActivityName in a safe way and use its methods working like callbacks:
((ActivityName)context).activityMethod()
Given that the getView() method of the Adapter class has a position parameter, is possible to pass this value to the activityMethod(int position) in order to know which list item has been pressed into the Activity where the ListView is.

Another solution.
if you have many child-control,and its to trouble to add android:focusable="false" to every child-control,you can add android:descendantFocusability="blocksDescendants" to its parent-control.try it.

I struggled with this for a while - none of the provided solutions worked for me. In the end I found that having a call to getListView() in my onViewCreated() method did the trick, although I have no idea why. This is for a Fragment rather than an Activity; not sure if this makes any difference.
public class NewsListFragment extends ListFragment {
private ListView listView;
...
#Override
public void onViewCreated(View view, Bundle savedInstanceState) {
newsListView = getListView();
}
#Override
public void onListItemClick(ListView l, View v, int position, long id) {
// this now works as expected
}
}

I was also struggling with this issue and none of the suggested solutions worked. My problem was that I did an override for onViewCreated but didn't call super.onViewCreated(view, savedInstanceState);. Hopefully this will help someone else so they don't spend hours trying to figure out what's going on.

I struggled as I by mistake put android:inputType="textCapWords" with the textbox after removing it it is fixed

Only the line below worked for me:
android:descendantFocusability="blocksDescendants"
The whole list_view_item.xml:
<?xml version="1.0" encoding="utf-8"?>
<!--android:focusableInTouchMode="false"-->
<!--android:focusable="false"-->
<!--android:clickable="false"-->
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="match_parent"
android:descendantFocusability="blocksDescendants"
android:layout_height="wrap_content">
<CheckBox
android:id="#+id/checkBox_list_view_checkBox"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<TextView
android:id="#+id/checkBox_list_view_textView"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>
The above is to be used in getView like:
convertView=LayoutInflater.from(getContext())
.inflate(R.layout.list_view_item, parent, false);
