How can I turn off suggestions in EditText?
android:inputType="textNoSuggestions"
according to this, may or may not be supported by the IME (the keyboard).
However, this seems to work more often
android:inputType="textNoSuggestions|textVisiblePassword"
It's already described in the link Yoni Samlan posted. You should read the documentation correctly ;)
There is a method called setInputType. All you need is to call it with
edittext.setInputType(InputType.TYPE_TEXT_FLAG_NO_SUGGESTIONS);
This seems to work better;
edittext.setInputType(InputType.TYPE_TEXT_FLAG_NO_SUGGESTIONS | InputType.TYPE_TEXT_VARIATION_VISIBLE_PASSWORD);
i.e. the visible password and no suggestion input types are OR'd together
To make sure you can also add this attribute to your edit text
android:inputType="textNoSuggestions|textVisiblePassword"
