EditText without auto-correction, etc
Solution 1:
Try this:
android:inputType="textFilter"
If that doesn't work, try:
android:inputType="textFilter|textNoSuggestions"
Solution 2:
You can do this from the code. Set the input type of the EditText like below:
txtEmail = (EditText) findViewById(R.id.txtEmail);
txtEmail.setInputType(InputType.TYPE_TEXT_FLAG_NO_SUGGESTIONS);
For a list of all the available input type options see http://developer.android.com/reference/android/text/InputType.html
Solution 3:
The other suggestions are correct, but SwiftKey has decided it will ignore the inputtype values "in response to user requests". While I agree this is a bad idea since it contradicts the Google guidelines and developers usually have a good reason for disabling auto-correction (like username fields, family names and so on), it still is the most used keyboard application for Android devices, so this can be a big problem.
The workaround is to use either
android:inputType="textVisiblePassword"
or
.setInputType(InputType.TYPE_TEXT_VARIATION_VISIBLE_PASSWORD);
Solution 4:
Try this if you want a multi-line EditText without displaying the underlines (auto correct):
myEditText.setInputType(InputType.TYPE_CLASS_TEXT |
InputType.TYPE_TEXT_FLAG_MULTI_LINE | InputType.TYPE_TEXT_FLAG_NO_SUGGESTIONS);
Here's XML for that: android:inputType="textNoSuggestions|textMultiLine"
.
