Setting EditText imeOptions to actionNext has no effect
Just add android:maxLines="1" & android:inputType="text" to your EditText. It will work!! :)
singleLine is deprecated. Adding an input type (eg: android:inputType="text") also worked for me.
Use android:maxLines="1" as singleLine is deprecated
android:singleLine has been deprecated, it is better to combine android:maxLines="1" with android:inputType="text". This would be the code:
<EditText android:id="@+id/editText" android:layout_width="wrap_content" android:layout_height="wrap_content" android:maxLines="1" android:inputType="text" />
