Hi,
Actually this is not the way that I am handling the alert dialogs
in my code:
In the oncreate, I have defined an alert dialog builder as follows:
onCreate():
AlertDialog.Builder alert_box_builder=new
AlertDialog.Builder(AsyncRecordTrial.this);
In various situations, I generate an alert dialog as follows:
Situation1:
alert_box = alert_box_builder.create();
alert_box.setIcon(R.drawable.icon);
alert_box.setMessage(dialogmessage);
alert_box.setButton("Ok",new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
dialog.cancel();
}
});
alert_box.setOnCancelListener(new OnCancelListener(){
@Override
public void onCancel(DialogInterface dialog) {
// TODO Auto-generated method stub
finish();
}
});
alert_box.show();
Similarly for Situation2:
alert_box = alert_box_builder.create();
...
...
alert_box.show();
Similarly for Situation3:
alert_box = alert_box_builder.create();
...
...
alert_box.show();
and so on...
Now sometimes, 2 or more of these alert dialog boxes gets generated on
top of each other. alert_box is not a global variable. I am not sure
how to keep track of the number of boxes that are showing up and how
to close the other boxes when ok is pressed for one?
Thank you,
B.Arunkumar
