How to transfer data of current item and create a new child cart on button click

I want to create a way which will add item to cart by creating a child cart the in that child it will retrieve current username and then under that it will save all the details of added item
this is the code of the fragment in which cart button is available (course = description,email = price,purl = url of image)

how can i add shuffle.collection or random to make my app show random question instead

You need to find out about Random class first in Java. Thereafter, you will create a random number using Random class in onClick function, then set a question's index to your Random number

You need to initialize the ArrayList<> first.
ArrayList<Film> film = new ArrayList<>();
film = this.getIntent().getParcelableArrayListExtra(EXTRA_MOVIE);
Then you can access it's value
txt_name = film.get(0).getName();
tvName.setText(txt_name);

What i am trying to achieve is when the user taps the list item, the input activity is loaded and the user can update the record. I wasnt able to find an elegant solution other than making an update method in MedicineInputActivity and then getting an instance of MedicineInputActivity in Medicine_Activity and calling update.
I am getting errors like "Attempt to invoke virtual method 'void com.example.shubhmgajra.medikit.MedicineInputActivity.update() on a null object reference".

You can return data from second activity to the first activity when user is done updating the record. You should start second activity by calling startActivityForResult() instead of startActivity() in the first activity. You should also override onActivityResult() in the first activity. You can read more here.
UPDATE:
I think you want to send selected medicine details from Medicine_Activity to MedicineInputActivity. In that case, you can send selected medicine object by binding it to the intent as follows:
public class Medicine_Activity ... {
#Override
protected void onCreate(Bundle savedInstanceState) {
...
listMeds.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
MedicineRecord medicineRecord = db.medicineRecordDao().findMedicineById(id + 1);
Intent intent = new Intent(getApplicationContext(), MedicineInputActivity.class);
intent.putExtra("selectedMedicine", medicineRecord);
startActivity(intent);
MedicineInputActivity.getInstance().update(medicineRecord, true);
}
});
...
}
}
Then on MedicineInputActivity, you should be doing this:
public class MedicineInputActivity ... {
MedicineRecord selectedMedicineRecord;
#Override
protected void onCreate(Bundle savedInstanceState) {
...
selectedMedicineRecord = (MedicineRecord) getIntent().getParcelableExtra("selectedMedicine");
...
}
}
To be able to do this, your MedicineRecord class should implement Parcelable interface.

Eclipse says onClickListener variable in Android cannot be resolved, but has been created?

In my project i several onClick listeners, and all of them are fine, but one, i can not find and error in the code, if i delete the code and retype it and save it, it is fine without errors, if i close and eclipse and comeback later, variable cant be resolved again.
This is where it cant be resolved in the code:
Button webButton = (Button) newStockRow.findViewById(R.id.webButton);
webButton.setOnClickListener(getStockFromWebClickListener);
and this is how i create it:
public OnClickListener getStockFromWebClickListener = new OnClickListener(){
#Override
public void onClick(View arg0) {
TableRow tableR = (TableRow) arg0.getParent();
TextView stock = (TextView) tableR.findViewById(R.id.stockSymbolTextView);
String stockSymbol = stock.getText().toString();
String stockURL = getString(R.string.yahoo_stock_url) + stockSymbol;
Intent getStockWebPage = new Intent(Intent.ACTION_VIEW, Uri.parse(stockURL));
startActivity(getStockWebPage);
}
};

That's indeed an annoying problem with importing an inner class (or interface) on Eclipse.
What you have to do is instead of:
new OnClickListener()
Write:
new View.OnClickListener()
And make sure that android.view.View is imported.
