happy new year to all of you.
I am having a problem with the method onItemClickListener, because when I tried to toast the position and id ,in my second activity, I get zeros.
here is the code, I rely on the position of the image in the array that is why I need to get the position/id accurately.
+
I am duplicating my array in both activities because I don't know how to access it from the second activity?

You misunderstand the way you should use intents.
The right form is like this :
int id =getIntent().getIntExtra("id",0);
int position = getIntent().getIntExtra("position", 0);
when you use getIntExtra , the second parameter is the default value. In case there is not such value with that tag in your intent, it will return that default value.
See Google docs for more info
You have to fetch value according the following way,
int id=0;
int position=0;
i=getIntent().getIntExtra("id",id);
position= getIntent().getIntExtra("position", position);
Toast.makeText( this, "id= " +id + " . and posistion= "+ position, Toast.LENGTH_LONG).show();

I am trying to make an app that takes the number of sets, and number of reps for each set from the user, and adds rows ( for each set) and checkboxes (for each rep)
for the reps: i made a method that takes the number of reps from the SQLite server, and loops through the number of reps to make the checkboxes.
for the sets: i made list adapter to make each row.
how can i make the reps be contained inside the rows? thanks.

Try creating a custom layout that will contain all the necessary views and pass the layout in the onCreateView of you adapter class with a layout inflater.
I am creating simple contacts app in android. MainActivity consist of listview displaying image and name. I am using a model for setting and getting data and ArrayList to pass the data to next activity. When I click on single listview item. It should display next activity displaying contact details.

you can do this to resolve your problem:
ls.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
//ContactModel contacts=new ContactModel();//here you did mistake
Intent intent=new Intent(getApplicationContext(),ContactDetails.class);
intent.putExtra("contacts",(Serializable) adapterView.getSelectedItem());
startActivity(intent);
}
});
In ls.setOnItemClickListener, you're passing ContactModel contacts=new ContactModel(); which is technically a blank object of ContactModel.
Now, when you're trying to set data in ContactDetails.java from that blank object that you got from Intent like this,
imageView.setImageResource(contacts.getImage());
nameView.setText(contacts.getName());
the contact object has no image or name (or other attributes for that matter) that has been previously set on it. Hence, you're getting a null pointer exception.
So, change it like below and your problem should get away.
ls.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
ContactModel contacts= contact_list.get(i);
Intent intent=new Intent(getApplicationContext(),ContactDetails.class);
Bundle bundle = new Bundle();
bundle.putSerializable("contacts",contacts);
intent.putExtras(bundle);
startActivity(intent);
}
});
And in ContactDetails.java, get the object like this.
Intent intent=getIntent();
Bundle bundle = intent.getExtras();
final ContactModel contacts=(ContactModel)bundle.getSerializable("contacts");
I have error message like this

The constructor BoxOfficeMoviesAdapter(FindPeopleFragment,
ArrayList) is undefined
In your Fragment use getActivity() instead of this when you pass context to the constructor.
Change this
adapterMovies = new BoxOfficeMoviesAdapter(this, aMovies);
to
adapterMovies = new BoxOfficeMoviesAdapter(getActivity(), aMovies);
The method setContentView(int, FindPeopleFragment) is undefined for
the type FindPeopleFragment
setContentView(R.layout.activity_box_office, this);
must be removed
setContentview is a method of Activity class not Fragment
Change to
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.activity_box_office,container,false);
// rest of the code
return view;
}
Further getView() returns null
Change this
lvMovies = (ListView) getView().findViewById(R.id.lvMovies);
to
lvMovies = (ListView) view.findViewById(R.id.lvMovies);
The constructor Intent(FindPeopleFragment,
Class) is undefined
Finally Change this
Intent i = new Intent(FindPeopleFragment.this, BoxOfficeDetailActivity.class);
to
Intent i = new Intent(getActivity(), BoxOfficeDetailActivity.class);
You better read the Fragment documentation before going any further.

Please Help me to solve this.
tv2.setText(pPrice);
pPrice is a int. setText(int) looks for a String id inside the R classes throwing a ResourceNotFoundException if the look-up fails. A quick fix is
tv2.setText(""+pPrice);
This way you are providing a String object to setText
Edit:
Change your getView this way:
#Override
public View getView(int position, View view, ViewGroup viewgroup) {
if (view == null) {
view=inflater.inflate(R.layout.pattern, null);
}
Listitem item = (Listitem)getItem(position)
TextView tv=(TextView) view.findViewById(R.id.nameview);
TextView tv2=(TextView) view.findViewById(R.id.pdesc);
TextView tv3=(TextView) view.findViewById(R.id.priceView);
tv.setText(item. pName);
tv2.setText(""+item.pPrice);
tv3.setText(item.pDisc);
return view;
}
You never get your objects from the ArrayList. Add this code to your getView() method:
ListItem item = arrayList.get(position);
tv.setText(item.pName);
tv2.setText(item.pPrice);
tv3.setText(item.pDisc);
I'm using ActionBar Sherlock and works fine.
This code works fine in 2.x but not in 4.x
The click only works in versions 2.x not working in 4.x versions I've tried many ways and I can not make the click function
what is the problem?
