why the onClickListener dont work? - eclipse

Question

I wrote this code and I want to use it when the user decide to exit my application.
when I activate it Eclipse telling me that there is an error with the yes button. This line is the problematic:yes.setOnClickListener(new View.OnClickListener() {
and this is the full code:
#Override
public void onBackPressed() {
// TODO Auto-generated method stub
super.onBackPressed();
final Dialog exitDialog = new Dialog(this);
exitDialog.setTitle("Exit");
exitDialog.setContentView(R.layout.exit_dialog);
yes.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
exitDialog.dismiss();
finish();
}
});
exitDialog.show();
}

Answer 1

There are 2 possible problems
1st because of this keyword it is referencing the current Dialog class so give your ClassName.this
2nd because of final keyword remove the final keyword and give the listener in onCreate(Bundle SavedInstances) method

Answer 2

How did you initialize the button yes? The recommended way is:
public void onBackPressed() {
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
builder.setMessage(R.string.dialog_quit)
.setPositiveButton(R.string.confirm, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
finish();
}
})
.setNegativeButton(R.string.cancel, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
}
});
Dialog dialog = builder.create();
dialog.show();
}
You can also refer to Android dialog guide.

Answer 3

You should use
button.addActionListener(new ActionListener() {
#Override
public void actionPerformed(ActionEvent e) {
exitDialog.dismiss();
finish()
}
});
instead of OnClickListener.
Another (better) option is to use JOptionPane.showConfirmDialog(...);
