滑动的时候会重绘,造成闪一下

[keaitao0321]

移动的时候会闪回初始状态再跳转

case MotionEvent.ACTION_MOVE: if (mode == DRAG && mDrag) { int dx = (int) (event.getRawX() - lastX); if (dx == 0) { return false; } int top = getTop(); Log.d("*****onTouchEvent", " dx" + dx + " left" + getLeft() + " right" + getLeft() + getWidth()); int left = getLeft() + dx; int right = left + getWidth();

                if (left >= 0) {
                    left = 0;
                    right = getWidth();
                }

                if (right < screenWidth) {
                    right = screenWidth;
                    left = right - getWidth();
                }
                layout(left, top, right, top + getHeight());
                 invalidate();
           

                lastX = event.getRawX();
                lastY = event.getRawY();

                int deltaX = (0 - left);
                int timeBarLength = getWidth() - screenWidth;
                currentTimeInMillisecond = mostLeftTimeInMillisecond + deltaX * WHOLE_TIMEBAR_TOTAL_SECONDS * 1000 / timeBarLength;

                if (mOnBarMoveListener != null) {
                    mOnBarMoveListener.onBarMove(getScreenLeftTimeInMillisecond(), getScreenRightTimeInMillisecond(), currentTimeInMillisecond);
                }
              
            }
