my dialog inheritance dialogFragment.
when I button click, show dialog.
but I button Click multiple times. show multiple dialog.(overlap dialog)
I want show only one dialog.
I try this.
if (dialog.getDialog().isShowing()){
//not showing dialog
} else {
dialog.show();
}
but not work.
how to show dialog overlapping protection on android?

Dismiss the dialog when its open already
if (dialog.isShowing()){
dialog.dismiss();
} else {
dialog.show();
}

If u want to prevent multiple click use some thing like this
button.setClickable(false);
new Handler().postDelayed(new Runnable() {
#Override
public void run() {
button.setClickable(true);
}
}, 2000);
