How to use View.OnTouchListener instead of onClick

I'm developing an Android 2.2.2 application for a client and he wants to do the following:

Now I have a button with an onClick event but he doesn't like, he wants to dectect when user release the button.

I've found View.OnTouchListener which I think this is what I need to use but, is there any posibility to add this event to xml like I did with onClick?

<ImageButton
    android:id="@+id/btnSaveNewGate"
    android:layout_width="@dimen/btnSaveNewGate_width"
    android:layout_height="@dimen/btnSaveNewGate_height"
    android:layout_below="@+id/radioGrGateType"
    android:layout_centerHorizontal="true"
    android:layout_marginTop="@dimen/btnSaveNewGate_marginTop"
    android:background="@null"
    android:contentDescription="@string/layout_empty"
    android:onClick="onSaveNewGateClick"
    android:scaleType="fitXY"
    android:src="@drawable/save_gate_selector" />

I have two questions more:

Which is the event associated when user releases his finger?

Is there any guidelines which prohibit using View.OnTouchListener instead of onClick?

for use sample touch listener just you need this code

@Override
public boolean onTouch(View view, MotionEvent motionEvent) {

    ClipData data = ClipData.newPlainText("", "");
    View.DragShadowBuilder shadowBuilder = new View.DragShadowBuilder(view);
    view.startDrag(data, shadowBuilder, null, 0);

    return true;
