How to disable hardware keyboard for a particular EditText ?

Question

HI.. This is my code in xml

<EditText android:longClickable="false"
                    android:layout_marginLeft="5dp" android:id="@+id/txt"
                    android:width="150dp" android:singleLine="true" android:text="@string/value"
                    android:inputType="none" android:cursorVisible="false" />

I have manually disabled soft keyboard in my application.

InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
        imm.hideSoftInputFromWindow(view.getApplicationWindowToken(), 0);

where view is the EditText. However I m unable to disable the input from hardware keyboard (slide keyboard) like the ones in droid for that particular EditText. How can this be achieved ?
