Intercept touch event SlidingPaneLayout

Question

I have an Activity with a SlidingPaneLayout, and inside there are two fragments: a ListView on the left, and a MapFragment on the right. How is it possible to intercept the touch event generated so that the user can move the map without close the panel?

The only area that I would like to use to close/open the right panel is the first fourth. On the right of that area I would like to move the map.

Thanks

EDIT2:

Ok, now I figured out how to properly subclass SlidingPaneLayout, now the problem is how to capture correctly the touch event:

@Override
public boolean onTouchEvent(MotionEvent event) {
    if (event.getAction() == MotionEvent.ACTION_DOWN
            && event.getX() > (getWidth() / 6)) {
        return false;
    }
    return super.onTouchEvent(event);
}

With this code I'm not able to slide the map, it remains fixed. the problem is that I want to intercept the touch ONLY when the right panel is selected (in other words, only when map is displayed).

SlidingPaneLayout have it's own touch listener, so when you reset it by calling setOnTouchListener (which is a method from the super class View) you are loosing all the onTouch behaviour specific to a SlidingPaneLayout.

-------------------------------

Here is a try : make your own SlidingPaneLayout :
the constructor should be this way in order to use your view in an xml layout

public class MySlidingPaneLayout extends SlidingPaneLayout{

    public MySlidingPaneLayout(Context context, AttributeSet attrs) {
        super(context, attrs);

    }

    @Override
    public boolean onTouchEvent(MotionEvent event){
        if (event.getX() < widthPIX / 6) {
             return super.onTouchEvent(event);// here it works as a normal SlidingPaneLayout
        }
        return false; // here it returns false so that another event's listener should be called, in your case the MapFragment listener
    }
}

and in your code add MySlidingPaneLayout instead

try it and tell me what you got – Sep 21 '13 at 13:57
Yes you are right but the line super.onTouchEvent(event) is wrong because super refers to class Object (it gives me compile error: "The method onTouchEvent(MotionEvent) is undefined for the type Object"). Probably I have to extend SlidingPaneLayout and then override the method onInterceptTouchEvent (I tried this a few time ago with a ViewPager and it worked) but now I'm not able to create a correct subclass of SlidingPaneLayout because it gives me different exceptions.. – Lorenzo Barbagli Sep 21 '13 at 14:01
oh am sorry i thought you were making your own SlidingPaneLayout by extending the SlidingPaneLayout class, i edited the answer – Sep 21 '13 at 14:10
Yeah, I tried that, but when I write the subclass I got this error: "Implicit super constructor SlidingPaneLayout() is undefined for default constructor. Must define an explicit constructor". And if a define a constructor, it gives me exceptions at runtime – Lorenzo Barbagli Sep 21 '13 at 14:24
will make another edit now to solve this simple problem of constructor – Sep 21 '13 at 14:34

I finally solved the problem: simply override this method and control if the SlidingPaneLayout is closed or open (in my case I have a boolean field value "open")

@Override
public boolean onInterceptTouchEvent(MotionEvent event) {
    if (!homeActivity.open && event.getX() > (getWidth() / 5)) {
            return false;
        }
    return super.onInterceptTouchEvent(event);
}
