Question

I’m trying to define an EditText but this warning is shown:

This text field does not specify an inputType or a hint.

The code in main.xml is:

<EditText android:id="@+id/input" 
              android:layout_width="fill_parent" 
              android:layout_height="wrap_content" 
              android:text="@string/textTest" /> 

How can I fix it?

Answer 1

You could add a hint :

android:hint="This will appear to the user if he didn't enter something yet in the EditText"

and a inputType so you could present to the user a better suited soft keyboard for the text he is suposed to enter in the EditText:

android:inputType="number"

will present a soft keyboard with only numbers and various signs.
Those are just warnings, you could ignore them but is better for the user to implement them.
