How to check if AlertDialog.builder is showing and cancelling it if its showing?

You can use AlertDialog methods for that.

AlertDialog alert = new AlertDialog.Builder(context).create();if (alert.isShowing()) {    alert.dismiss();}

Hope it helps.

An alternative approach is to use a method to generate the AlertDialog with a builder and then create the AlertDialog without showing it while setting the AlertDialog to a class variable.

Then check with .isShowing(); method

Example:

AlertDialog mAlertDialog;public showMyAlertDialog(View layout){    AlertDialog.Builder builder = new AlertDialog.Builder(getContext());    builder.setView(layout);    builder.setNeutralButton(getString(android.R.string.ok),new DialogInterface.OnClickListener() {        @Override        public void onClick(DialogInterface dialog, int which) {            dialog.dismiss();            mAlertDialog = null; //setting to null is not required persay        }    });    mAlertDialog = builder.create()    mAlertDialog.show();}public boolean isAlertDialogShowing(AlertDialog thisAlertDialog){    if(thisAlertDialog != null){        return thisAlertDialog.isShowing();    }}

hope that it is understood how to use this source.cheers

AlertDialog extends Dialog which has isShowing().

Hint: AlertDialog.Builder creates an AlertDialog instance. :)
