Creating custom alert dialog in Android Studio
I am building a android app using Android Studio.
I need to create a custom alert dialog, with a TextView and a Spinner, to prompt a user to edit values saved in a list. I am currently using a default alert dialog to edit the one variable in the list (quantity of the item selected), but I must now be able to edit both variables (quantity and tax amount). The quantity will be a simple int, and the tax amount is a predefined variable list found in each users personal database.
What is the best way to create and implement a custom alert dialog for users to edit their lists?

You have to extends Dialog and implements OnClickListener
public class CustomDialogClass extends Dialog implements
android.view.View.OnClickL
public Activity c;
public Dialog d;
public Button yes, no;
public CustomDialogClass(Activity
super(a);
// TODO Auto-generated constructor stub
this.c = a;
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstan
requestWindowFeature(Windo
setContentView(R.layout.cu
yes = (Button) findViewById(R.id.btn_yes)
no = (Button) findViewById(R.id.btn_no);
yes.setOnClickListener(thi
no.setOnClickListener(this
}
@Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.btn_yes:
c.finish();
break;
case R.id.btn_no:
dismiss();
break;
default:
break;
}
dismiss();
}
}
How to Call Dialog ?
R.id.TXT_Exit:
CustomDialogClass cdd=new CustomDialogClass(Values.t
cdd.show();

How to Call Dialog ?
R.id.TXT_Exit:
CustomDialogClass cdd=new CustomDialogClass(Values.t
cdd.show();
When implementing this exact example, I seem to get a error when trying to call the dialog? "CustomDialogClass cdd=new CustomDialogClass(Values.t
I also need to send information to and from this dialog, as this is to edit a list (dataset) from the initial activity. Could you please clarify how to call this dialog, as well as how to send and receive data so that I may use it to edit existing data on the initial activity where I call it?
