Java – use dialoginterface Onclicklistener distinguishes a single dialog
•
Java
We have two alertdialog objects
AlertDialog dialog1,dialog2;
Both dialog boxes are through alertdialog Created by builder How do we recognize dialoginterface Which dialog box in onclicklistener is the event source?
Using a single dialog box, we can do this:
AlertDialogInstance.setOnClickListener(myListener);
//myListener
public void onClick(DialogInterface arg0,int arg1) {
switch (arg1) {
case AlertDialog.BUTTON_NEGATIVE:
// do something
break;
case AlertDialog.BUTTON_POSITIVE:
// do something
break;
case AlertDialog.BUTTON_NEUTRAL:
// do something
break;
}
}
How can I modify this switch logic to handle multiple dialog boxes? (or, if there is a better system to handle dialog boxes, what is it except inline button callback?)
Solution
I suggest you put the param you need in the custom listener
private class CustomOnClickListener implements OnClickListener {
private int id;
public CustomOnClickListener(int id) {
this.id = id;
}
public void onClick(DialogInterface dialog,int which) {
//check id and which
}
}
Then, when you add onclicklisteners to the dialog box, you simply provide the listener with an ID
