(Android) Check if EditText is empty?

Question

How do you check if an EditText is empty? I want to make it so that if the EditText is blank, a TextView value will be " " (space). If it's not, resume as normal. How do I go about doing this? Thanks for the help!

Answer 1

to check Edittext as empty ,where myeditText is your edittext

if(myeditText.getText().toString().trim().length() == 0)

Or use below function

   private boolean isEmpty(EditText myeditText) {
            return myeditText.getText().toString().trim().length() == 0;
        }

If function return false means edittext is not empty and return true means edittext is empty

Answer 2

EditText has a method getText() which returns an instance of Editable and the Editable class has a method: length(). If the lenght is not 0, your EditText is not empty.

Answer 3

String text=yourEditText.getText().toString().trim();
if(text.equal("") || text==null) {
    //Do Somthing...
} 
else {
    //Do something else
}

Good luck

Answer 4

If you go through EditText API reference, getText() will return the text as Editable. You can use it like

if(!TextUtils.isEmpty(myeditText.getText().toString().trim()) {
// Non-empty 
}
