In my application i've a line for increasing the width of a widget(by dragging the line to right/left) and i've the ScrollView
enabled in the same activity. I need to disable the scroll view action when the user touches the line and when user releases, it should be enabled. The ScrollView
should be in visible state but the action of the scroll view should be disabled. Please help me in solving this problem. I've tried with these but none of them is working.
scroll.setEnabled(false);
scroll.setFocusable(false);
scroll.setHorizontalScrollBarEnabled(false);
scroll.setVerticalScrollBarEnabled(false);
Thanks in advance.
If anyone's using Android L or later and overriding
onTouch
andonInterceptTouchEvent
isn't working:try overriding
onStartNestedScroll
andreturn false
.There is also a new XML attribute
nestedScrollingEnabled
, but it seems like it has to be on the View that is leaking the scroll event, rather than on the ScrollView being affected by the leak, or anywhere in the layout hierarchy between them. So if you don't know in advance what child ScrollViews you might have, overridingonStartNestedScroll
for the affected ScrollView is the way to go.This is a bit late, but an even easier way is to just get your parent
ViewGroup
and callrequestDisallowInterceptTouchEvent(true)
on it. This causes not only the immediate parent (scroll view) but any other parent objects that might intercept the touch to ignore it for the duration of the particular event. This is great when you have a draggable child AND draggable parent, and want to disable parent dragging while the child is being dragged.It's also a more general solution than specifically disabling the scroll view. If you re-use your draggable child view somewhere else, it will still work: You don't need to know the scroll view's ID. Code that's re-usable without modification is always good.
This might be a bit late but I ran into the same problem so my solution is similar to above, had to disable the OnTouchListener as follows:
