Show Error on the tip of the Edit Text Android

Question

I want to show error if the user enters blank value in the edittext.But i am not getting the way how could i do this .This is how i want like this:

Answer 1

Simple way to implement this thing following this method

1st initial the EditText Field

  EditText editText = findViewById(R.id.editTextField);

When you done initialization. Now time to keep the imputed value in a variable

  final String userInput = editText.getText().toString();

Now Time to check the condition whether user fulfilled or not

  if (userInput.isEmpty()){
           editText.setError("This field need to fill up");
       
        }else{
         //Do what you want to do
      }

Here is an example how I did with my project

  private void sendMail() {
       final String userMessage = etMessage.getText().toString();
          if (userMessage.isEmpty()) {

            etMessage.setError("Write to us");

    }else{
       Toast.makeText(this, "You write to us"+etMessage, Toast.LENGTH_SHORT).show();
      }
   }

Hope it will help you.
