addIgnoredView : ignored view "hitrect" is in parent coordinates

[tlevavasseur]

Ignored View hitrect is in parent coordinates which may not start at 0;0.

I used View.getGlobalVisibleRect to make it work with my ignored view :

private boolean isInIgnoredView(MotionEvent ev) {
    Rect rect = new Rect();
    for (View v : mIgnoredViews) {
        v.getGlobalVisibleRect(rect);
        if (rect.contains((int)ev.getX(), (int)ev.getY())) return true;
    }
    return false;
}

It works!

First, sorry for my English ;)

I agree with tlevavasseur, the hitRect method returns rect regarding the parent coordinates. It works if you add the content view in ignored views list but not if you add a child view... Using View.getGlobalVisibleRect is a good solution but we have to add a global offset point to obtain the correct rect calculation :

private boolean isInIgnoredView(MotionEvent ev) {
    Rect rect = new Rect();
    for (View v : mIgnoredViews) {
        int location[] = {0,0};
        v.getLocationOnScreen(location);
        v.getGlobalVisibleRect(rect, new Point(location[0], location[1]));
        rect.offset(0, - rect.height()/2);
        if (rect.contains((int)ev.getX(), (int)ev.getY())) return true;
    }
    return false;
}

Maybe it's not the best solution but it works in my case (ignore an horizontal scrollview contained into several layouts).

Note : I added an offset because my Y rect position is defined on center (maybe because my layout is vertically centered, ths pivotY is defined on center... I don't know :D)

Remarks to Bismuth76 comment:

1. getGlobalVisibleRect can return false if view is not visible
2. MotionEvent's getX() and getY() can return absolute or local coordinates (it is context-related)

So my version of method is following:

private boolean isInIgnoredView(MotionEvent ev) { Rect rect = new Rect(); for (View v : mIgnoredViews) { int[] location = {0,0}; v.getLocationOnScreen(location); if (v.getGlobalVisibleRect(rect, new Point(location[0], location[1])) && rect.contains((int)ev.getRawX(), (int)ev.getRawY())) return true; } return false; }

nice work, It's very helpful
