I guess I am late but use following together to make it work:
android:inputType="none"
android:enabled="false"
EditText mEdit = (EditText) findViewById(R.id.yourid);
mEdit.setEnabled(false);
<EditText android:id="@+id/outputResult"
android:inputType="text"
android:editable="false"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/result" />
