How can the 'widget' layers in the ViewGroup get the event before ScrollView so I can call getParent().onRequestDisableInterceptTouch() ... or is it getParent().getParent().onRequestDisableInterceptTouch()?

在此先感谢

推荐答案

可口可乐和放大器经过一夜好;调试我设法得到这个工作。我同意的解决方案，以防万一有兴趣的人，因为我花了相当多的时间来运行它。

Well after a night of coca cola & debugging I managed to get this to work. I share the solution just in case it is of interest to anyone, because it took me quite a lot of time to get it running.

我没把它与的getParent（）运行。onRequestDisableInterceptTouch（），我很接近，但无法找到一种方法为孩子小部件得到他们所需要的滚动一次MotionEvents我拦截父的触摸，所以尽管外周涡旋是prevented正确，内部部件不滚动。

I didn't manage to get it running with getParent().onRequestDisableInterceptTouch(), I was close, but couldn't find a way for the child widgets to get the MotionEvents they need for scrolling once I intercepted the touch on the parent, so even though the outer scroll was prevented correctly, the inner widgets didn't scroll.

所以，解决的办法就是 interceptTouchEvents 在孩子只有，然后如果孩子是滚动（称为属性），和触摸是ACTION_DOWN ，然后禁用滚动型两级以上。如果触摸是ACTION_UP，我们启用了滚动视图。

So the solution is to interceptTouchEvents in the children ONLY, and if the children is scrollable (known property), and the touch is ACTION_DOWN, then disable the scrollview two levels above. If the touch is ACTION_UP, we enable the scrollview.

要启用/禁用滚动视图我刚拦截触摸事件，并与一个标志筛选事件或不

To enable/disable the scrollview I just intercept the touch event and with a flag filter the event or not.

我做了三个辅助类，一个是滚动型，一为容器，一个用于小部件：

I did three auxiliary classes, one for the ScrollView, one for the Container, One for the widgets:

本类包装每一个部件，如果我叫setNeedsScroll（真），那么倒是会被拦截，当它被触摸，它会（告诉容器）告诉滚动视图禁用本身。当触摸被释放时，它将重新启用滚动视图。

This class wraps every widget and, if I call setNeedsScroll(true) , then touches will be intercepted, and when it is touched, it will (tell the container to) tell the scrollview to disable itself. When the touch is released, it will re-enable the scrollview.

class WidgetWrapperLayout extends FrameLayout {

    private boolean mNeedsScroll=false;

    public WidgetWrapperLayout(Context context) {
        super(context);
    }

  /** Called anytime, ie, during construction, to indicate that this 
    * widget uses vertical scroll, so we need to disable its container scroll 
    */

    public void setNeedsScroll(boolean needsScroll) { 
        mNeedsScroll=needsScroll; 
    }

    @Override
    public boolean onInterceptTouchEvent(MotionEvent ev) {
        if (mNeedsScroll)  {
            switch (ev.getAction()) {  
            case MotionEvent.ACTION_DOWN:
                ((SlideLayout)getParent()).setEnableScroll(false);
                break;
            case MotionEvent.ACTION_UP:
                ((SlideLayout)getParent()).setEnableScroll(true);
                break;
            }
            return false;
        }
        return super.onInterceptTouchEvent(ev);
    }
}

这是容器，独生子女滚动视图，并拥有不同的小部件。它只是提供了对孩子的方法，使他们能启用/禁用滚动：

This is the container, only child of the scrollview, and holds the different widgets. It just provides methods for the children so they can enable/disable the scroll:

public class ContainerLayout extends FrameLayout {

    public ContainerLayout(Context context) {
        super(context);
    }

    public void setEnableScroll(boolean status) {
        if (Conf.LOG_ON) Log.d(TAG, "Request enable scroll: "+status);
        ((StoppableScrollView)getParent()).setScrollEnabled(status);
    }
}

和最后一个滚动视图能够失活。它禁用滚动老斯库尔，拦截和阻断事件。

and finally a scrollview capable of deactivation. It disables the scroll 'old-skool', intercepting and blocking events.

public class StoppableScrollView extends ScrollView {

    private String TAG="StoppableScrollView";

    private boolean mDisableScrolling=false;

    public StoppableScrollView(Context context) {
        super(context);
    }

    /** Enables or disables ScrollView scroll */
    public void setScrollEnabled (boolean status) { 
        if (Conf.LOG_ON) Log.d(TAG, "Scroll Enabled "+status);
        mDisableScrolling=!status; 
    }


    @Override
    public boolean onInterceptTouchEvent(MotionEvent ev) {
        if (mDisableScrolling) return false;
        return super.onInterceptTouchEvent(ev);
    }
}
