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" />

Buttons for ListView Not Showing

please can you help me with the following issue. I’m trying to develop a contact directory as part of my app which allows the user to click a call and email button next to each contact and perform the relevant action. The directory displays fine however:
1) The call and email buttons in the phonebook_row.xml class are not being displayed when I run the app. How can I fix this issue?
2) How can I make the call and email clickable buttons which take just the phone number and email (without ‘Name:’ and ‘Email’) from the strings it is stored next to and open the number in phone dialler/create new email with email address?
My code is as follows…
Directory.java:
import android.graphics.Bitmap;
public class Directory {
private Bitmap mAvatar;
private String mName;
private String mPhone;
private String mEmail;
private String mLocation;
public Directory(Bitmap mAvatar, String mName, String mPhone, String mEmail, String mLocation) {
this.mAvatar = mAvatar;
this.mName = "Name: " + mName;
this.mPhone = "Phone Extension: " + mPhone;
this.mEmail = "Email: " + mEmail;
this.mLocation = "Location: " + mLocation;
}
public Bitmap getmAvatar() {
return mAvatar;
}
public void setmAvatar(Bitmap mAvatar) {
this.mAvatar = mAvatar;
}
public String getmName() {
return mName;
}
public void setmName(String mName) {
this.mName = mName;
}
public String getmPhone() {
return mPhone;
}
public void setmPhone(String mPhone) {
this.mPhone = mPhone;
}
public String getmEmail() {
return mEmail;
}
public void setmEmail(String mEmail) {

In the get view method of your adapter class you can do the following, notice I use an imageview in the example and its only for the calling part. A button would have the same implementation.
ImageView icon = (ImageView)view.findViewById(R.id.callicon);
icon.setImageResource(R.drawable.ic_action_call);
icon.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
//----create new intent for the call action and give it the number
//this will just start the dailer but not complete the action
Intent callIntent = new Intent(Intent.ACTION_DIAL,
Uri.parse("tel:" + entry.getmPhone()));
callIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(callIntent);
}
});

Your listview needs a height, it cannot be wrap_content. Give it a height like 500dp or match_parent.

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.

listview item is not added on button click

I have an issue with adapter adding data to listview on button click.
I have a activity called createteam that has name and email edittext and a createplayer button. On click createplayer button, the name and email should be added to list view.
I want to use an adapter for doing that(so that I can learn).
Update:
Onclicking the button the the first entry gets added but when I fill in the
edittexts again, the listview does get updated. I am notifying the adapter when I update
the data but only first entry gets and remains added to list view

Change your code like this. You are not setting values to v variable.

onClick of your button call list.notifyDataSetChanged(). It will refresh your list.
Incase if doesn't work just check getCount() of your adapter what value it is returning. If it is returning 0 your list will not show any data even you call list.notifyDataSetChanged().
Make an arrayList in your adapter and add new items into that. and from getCount() return size of arrayList.
