How to prevent alert dialog from appearing when some condition is fulfilled? - android-studio

Question

//NotificationPermission Dialog
private void notificationPermissionDialog(){
AlertDialog dialog = new AlertDialog.Builder(getActivity())
.setCancelable(false)
.setMessage("Do you want to Enable Notifications?")
.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialogInterface, int i) {
savePermissionInPreferences("Yes");
dialogInterface.dismiss();
}
}).setNegativeButton("No", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialogInterface, int i) {
savePermissionInPreferences("No");
dialogInterface.dismiss();
}
}).show();
}
//Save Notification Permission in Preferences
private void savePermissionInPreferences(String isNotificationAllowed){
SharedPreferences sharedPreferences;
sharedPreferences = getContext().getSharedPreferences("PermissionPref", Context.MODE_PRIVATE);
SharedPreferences.Editor editor = sharedPreferences.edit();
editor.putString("isNotificationAllowed", isNotificationAllowed);
editor.apply();
}
I have created a dialogue which appears when fragment is opened and ask for permission if I click on NO its value is saved in shared preference for preventing it to appear again but when I replace my fragment in same activity dialogue appears again and again. Please anyone can guide me through it.
Thanks in advance.

Answer 1

So you can do something like below
private void notificationPermissionDialog(){
SharedPreferences sharedPreferences = getSharedPreferences("PermissionPref", Context.MODE_PRIVATE);//Add these
String permission = sharedPreferences.getString("isNotificationAllowed", "");
//Add this line
if(!permission == "No"){
AlertDialog dialog = new AlertDialog.Builder(getActivity())
.setCancelable(false)
.setMessage("Do you want to Enable Notifications?")
.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialogInterface, int i) {
savePermissionInPreferences("Yes");
dialogInterface.dismiss();
}
}).setNegativeButton("No", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialogInterface, int i) {
savePermissionInPreferences("No");
dialogInterface.dismiss();
}
}).show();
}
}
//Save Notification Permission in Preferences
private void savePermissionInPreferences(String isNotificationAllowed){
SharedPreferences sharedPreferences;
sharedPreferences = getContext().getSharedPreferences("PermissionPref",
Context.MODE_PRIVATE);
SharedPreferences.Editor editor = sharedPreferences.edit();
editor.putString("isNotificationAllowed", isNotificationAllowed);
editor.apply();
}
If the user selected no to the Alert Dialog it wont appear again.
