Android: Check if EditText is Empty when inputType is set on Number/Phone

Question

I have an EditText in android for users to input their AGE. It is set an inputType=phone. I would like to know if there is a way to check if this EditText is null

Answer 1

Try this. This is the only solution I got

String phone;   

 try{
phone=(EditText) findViewByID(R.id.age)).getText().toString();

}
catch(NumberFormatException e){

 Toast.makeText(MainActivity.this, "plz enterphone Number ", Toast.LENGTH_SHORT).show();
    return;

}
