Android – toast appears multiple times
•
Android
In my application, click on the button I create a toast as –
Toast.makeText(context,"Please Enter Username",Toast.LENGTH_SHORT).show();
But when someone clicks the button 5-6 times and closes the application, or enters another screen, it will still continue to display toast on the other screen for some time. I've seen many of the same solutions
I tried –
toast = Toast.makeText(LoginActivity.this, message, Toast.LENGTH_SHORT);
toast.show();
And canceled the toast –
onPause(){
if(toast!=null){
toast.cancel();
}
Same as ondestroy()
I hope that when anyone clicks the button 5-6 times and exits the application or the activity, the toast message should disappear. Or suggest any alternative solution
resolvent:
You can create a field variable and method that displays only one toast at a time:
Toast toast;
public void displayToast(String message) {
if(toast != null)
toast.cancel();
toast = Toast.makeText(context, message, Toast.LENGTH_SHORT);
toast.show();
}
And cancel any existing toast when onpause() exits:
protected void onPause() {
if(toast != null)
toast.cancel();
super.onPause();
}
Now, whenever you want to display toast, just call:
displayToast("Please Enter Username");
