Toast when fields are Empty in Application

Question

I want to display toast when fields are empty.

button1.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            aut.signInWithEmailAndPassword(edittext1.getText().toString(), edittext2.getText().toString()).addOnCompleteListener(MainActivity.this, _aut_sign_in_listener);
        }

    });

Before doing that

aut.signInWithEmailAndPassword(edittext1.getText().toString(), edittext2.getText().toString()).addOnCompleteListener(MainActivity.this, _aut_sign_in_listener)

Try to check if data is empty as follow

if (edittext1.getText().toString().isEmpty() || edittext2.getText().toString().isEmpty()) {
    Toast.makeText(this,"fill the required field",Toast.LENGTH_LONG).show();
} else {
    aut.signInWithEmailAndPassword(edittext1.getText().toString(), edittext2.getText().toString()).addOnCompleteListener(MainActivity.this, _aut_sign_in_listener)
}

Aditionally to correct @Pritam's answer use `TextUtils.isEmpty(edittext1.getText().toString())` instead `.isEmpty()` – Abner Escócio Jul 30 '18 at 12:46

Try this :

When the fields are empty, apply this check :-

if (edittext1.getText().toString().isEmpty()) {

Toast.makeText(getApplicationContext(),"Edit text 1 can not be empty",Toast.LENGTH_LONG).show();

}

else if (edittext2.getText().toString().isEmpty()) {
Toast.makeText(getApplicationContext(),"Edit text 2 can not be empty",Toast.LENGTH_LONG).show();
   }
    else{
     //success code here
        aut.signInWithEmailAndPassword(edittext1.getText().toString(), edittext2.getText().toString()).addOnCompleteListener(MainActivity.this, _aut_sign_in_listener);

    }

Instead of toast, "setError" to edit texts. It would be better

editText.setError("This field can not be blank");

Try this,

button1.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
        if(edittext1.getText().toString().length()<=0){
            Toast.makeText(this, "email is empty", Toast.LENGTH_SHORT).show();
        }else if (edittext2.getText().toString().length()<=0){
            Toast.makeText(this, "password is empty", Toast.LENGTH_SHORT).show();
        }else{
            aut.signInWithEmailAndPassword(edittext1.getText().toString(), edittext2.getText().toString()).addOnCompleteListener(MainActivity.this, _aut_sign_in_listener);
        }
    }

});
