how to disable spellcheck Android edittext

Or if you want to just disable the red underline (and the autocorrect dialog), you can override the isSuggestionsEnabled() method on TextView.

This will keep the keyboard autocomplete working.

Minor addition to Chintan's answer - such (and other) combination is also allowed:
android:inputType="textCapSentences|textNoSuggestions"

You can do it with following code. Just paste it in layout of EditText.

android:inputType="textNoSuggestions"

In order to get rid of spell checking you have to specify the EditText's InputType in the XML as the following:

android:inputType="textNoSuggestions"

However, if your EditText is multiline and also you need to get rid of spell checking,then you have to specify the EditText's InputType in the XML as the following:

android:inputType="textMultiLine|textNoSuggestions"
