Handling clicks inside listview

I'm new in Android and need help with my ListView, which contains text view and image in every list item. I need handle clicks on list item and on icon (R.id.list_star) in list item separately. I tried several ways but it seems I can't do it by myself. I tried to put star.setOnItemClickListener in the beginning, near lvData.setOnItemClickListener - but in this case view isn't found, and add swith inside AdapterView.OnItemClickListener - doesn't work. My code handles only list item click but no icon clicks

AsyncTaskLoader's onStartLoading() isnt being called

I have this custom Loader that is supposed to insert some dummy data I sent to it in a database using content resolver. I'm using the getLoaderManager().initLoader(INSERT_DUMMY_DATA_ID, null, this);
in the activity. The constructor gets called. But the onStartLoading() and loadinBackgroung() arent called.
Here is the ProductInsertionLoader.java
public class ProductInsertionLoader extends AsyncTaskLoader {
private String LOG_TAG = ProductInsertionLoader.class.getSimpleName();
private ArrayList<ContentValues> mValues;
private ContentResolver mContentResolver;
public ProductInsertionLoader(Context context, ContentResolver contentResolver, ArrayList<ContentValues> values) {
super(context);
mValues = values;
mContentResolver = contentResolver;
Log.v(LOG_TAG, "constructor called");
}
#Override
public Object loadInBackground() {
Log.v(LOG_TAG, "loadInBackground() called");
ArrayList<Uri> uris = new ArrayList<>();
for (ContentValues value : mValues) {
Uri uri = mContentResolver.insert(ProductContract.ProductEntry.CONTENT_URI, value);
Log.v(LOG_TAG, "Dummy data inserted. ID: " + ContentUris.parseId(uri));
uris.add(uri);
}
return null;
}
#Override
protected void onStartLoading() {
Log.v(LOG_TAG, "onStartLoading() called");
forceLoad();
}
}
Here is how I'm calling it in the CatalogActivity.java

As you can see I'm using two loaders. One CursorLoader to load all the database data into the UI, and a second custom AsyncTaskLoader to insert some dummy data on to the database on a background thread.
Why isn't the custom loader's onStartLoading() or loadInBackground() not being called?

SQLite database and ListView not syncing up properly, off by 1 number

I'm having trouble with my database and I can't seem to track down the problem. I'm an Android noob.
Whenever I add a term or delete a term, the data seems to be loading for the wrong listview item that I click on.
I had to modify the id before sending it to the intent to try to fix it but I keep getting errors.
Here is my datasource code:

I can only figure one of my methods in my DataSource is wrong, or perhaps I'm using the wrong code somewhere between the two Activities.

in TermActivity, you need to get the id by the position of item in Adapter, not the id:
#Override
public void onListItemClick(ListView listView,
View itemView,
int position,
long id){
Intent intent = new Intent(getApplicationContext(), TermViewActivity.class);
// get the id of object by its position in
// the adapter
Term term = getListView().getItemAtPosition(position);
long itemId = term.getId();
intent.putExtra(TermViewActivity.EXTRA_TERMNO, itemId);
startActivity(intent);
}

Bug in app while rotating Android phone

hello guys i started to learn to build android applications via udacy. After a long troubleshooting i didnt find something that can cause the bug that i have. the bug is that when i rotate the phone the view seems to clone it self and not deleting the previous one if someone can help me ill be very happy.
1) normal state of app:
2) after rotation:
3) and after another rotation the application crashing
it never happend until i added the code in the xml file of the view:
<?xml version="1.0" encoding="utf-8"?>

Two activities sending data to each other

Two activities are sending data to each other.
The first activity has a custom list view. The second has one text view and three buttons to increase and decrease a value.
When I click on the first activity, the second activity opens. The second activity increases the text view value and clicked the button. Data goes to the first activity. Same process again.
My problem is that the total value is not displayed in the first activity.
How can i show all increase and decrease values from the second activity in the first activity?
