我有一个使用 RadioButtons 作为其句柄的自定义可拖动 SlidingDrawer。为了在 RadioButtons 上启用触摸事件，我调用return super.onInterceptTouchEvent(event);而不是return true在onInterceptTouchEvent方法上。但不知何故，每次我想拖动我的 SlidingDrawer 时，我都无法通过准确地触摸 RadioButtons 来拖动它，我必须向上移动一点手指才能将 SlidingDrawer 向上拖动。

有什么方法可以通过触摸其 RadioButtons 来使 SlidingDrawer 完全可拖动，而不会丢失 RadioButtons 本身上的 TouchEvent？

这是我的触摸方法：

public boolean onInterceptTouchEvent(MotionEvent event) {

            if (mLocked) {
                //return false;
            }

            final int action = event.getAction();

            float x = event.getX();
            float y = event.getY();

            final Rect frame = mFrame;
            final View handle = mHandle;

            handle.getHitRect(frame);
            if (!mTracking && !frame.contains((int) x, (int) y)) {
                return false;
            }

            if (action == MotionEvent.ACTION_DOWN) {
                mTracking = true;
                WWHApplication.getListActivityIntance().resizeListView(1800);
                handle.setPressed(true);
                // Must be called before prepareTracking()
                prepareContent();
                // Must be called after prepareContent()
                if (mOnDrawerScrollListener != null) {
                    mOnDrawerScrollListener.onScrollStarted();
                }

                if (mVertical) {
                    final int top = mHandle.getTop();
                    mTouchDelta = (int) y - top;
                    prepareTracking(top);
                } else {
                    final int left = mHandle.getLeft();
                    mTouchDelta = (int) x - left;
                    prepareTracking(left);
                }
                mVelocityTracker.addMovement(event);
            }

            //return true;
            return super.onInterceptTouchEvent(event);

        }

这是我的手柄的样子
