I am new to android and have faced some problem, I am making a StudentArraylist to view the student from my firebase database to show them in ListView. But I face some problem because the code I have now I meant for fragment but not activity and
Here is my error
This is the ViewStudentActivity
StudentArrayList adapter = new StudentArrayList(getActivity(),studentList);
studentlist.setAdapter(adapter);
This is the StudentArrayList:
public StudentArrayList(Activity context, List<Student>studentList){
super(context, R.layout.student_list, studentList);
this.context = context;
this.studentList = studentList;
}
#NonNull
#Override
public View getView(int position, #Nullable View convertView, #NonNull
ViewGroup parent) {
LayoutInflater inflater = context.getLayoutInflater();
View listViewItem = inflater.inflate(R.layout.student_list, null, true);
s_sid = (TextView)listViewItem.findViewById(R.id.txtSid);
s_name = (TextView)listViewItem.findViewById(R.id.txtName);
s_email = (TextView)listViewItem.findViewById(R.id.txtEmail);
s_fyp = (TextView)listViewItem.findViewById(R.id.s_fyp);
btnUpdate = (Button) listViewItem.findViewById(R.id.btnUpdate);
firebaseDatabase = FirebaseDatabase.getInstance();
pdatabaseReference = firebaseDatabase.getReference();
auth = FirebaseAuth.getInstance();
final Student student = studentList.get(position);
s_sid.setText("Student ID : " + student.gets_sid());
s_name.setText("Student Name : " +student.gets_name());
s_email.setText("Date : " +student.gets_email());
s_fyp.setText("Time Start : " +student.gets_fyp());
return listViewItem;

I am trying to delete a record trough listview from database. I am somehow got suceed in removing the record from list but didn't find any help to delete it from database.
Below is the code of my adapter. Any help will be appreciated.

First of all I'm sorry for my bad English :X
Iam quite a newbie in Android App development and Iam about to develope an app which gives the user informations like free park-places in town.
The app is based on Google Maps.
My Problem:
My app starts and shows a Google Maps Layout. Over an ExpandableListView the User can open a overview about the Parking-Locations.
If the user click on a Child Item in the ExpListView a new Cluster item should be generated at the MapsLayout.
How can I give the OnClick data to the MainActivity? I want that the MainActivity 'knew' which Item is clicked by the User!
Im glad about every answer :)

Solved! After research I make ExpandableAdpater an inner class of MapsActivity! Now i can put data between both classes and use Methods also!
I have some question regarding Android programming. More specific, I have a ListView where every single row is containg five widgets and each trigger event. I have created custom adapter and defined events handler for every widgets in the getView method. Everything works fine, however the code looks quite long, unreadable and nasty because of all these event handlers inside. Is there any better design? Maybe Creating event handlers outside the getView method or something else?
greetings
According to suggestion I posted part of the source code. As you can see I have created few event handlers outside the getView method and two inside. I really do not know which design is better.

}![here you have screen shoot of single row][1]
Create a single instance of OnClickListener (for example as an inner class) and assign this instance to every widget. If you need to know which row this widget belongs to, you can call setTag("pos", position) on that widget. By doing this you will be able to get position by calling view.getTag("pos") in onClick(View view) method of the listener. Hope this helps.
I have a listview in my main activity.In each row i have a image view,when i click that image view QuickAction(Like popover in ios) will appears.My request is, I want to setText the text from listview to the another Activity's edittext when i click the action item in the quick action.Please help..

just pass the string to your activity and change the parameter of the functiontorun as string
I'm trying to show a list with the list items from my database having 2 parameters, but the list didn't show.
Here's my query database from php:
$query = mysql_query("SELECT d.model_name from detail_product d join brand b on d.id_brandtype = b.id_brand join biketype t on d.id_biketype = t.id_type where d.id_brandtype = 1 and d.id_biketype=1");
I've set the parameter there.
