标签:桌面滑动

下面我们把这个控件内嵌到Layout中做一些动画和展示,效果图:

bubuko.com,布布扣


这个子控件可以上下移动,可以左右滑动,如果上下滑动距离大于左右滑动距离,则必须上下滑动

这样来写onTouch事件:

	@Override
	public boolean onTouchEvent(MotionEvent ev) {

		if (mVelocityTracker == null) {
			mVelocityTracker = VelocityTracker.obtain();
		}
		mVelocityTracker.addMovement(ev);

		int mScrollX = this.getScrollX();

		final int action = ev.getAction();
		final float x = ev.getX();
		final float y = ev.getY();

		switch (action) {
		case MotionEvent.ACTION_DOWN:
			mFlagLimitMove = false;
			mFlagLimitUp = false;
			/*
			 * If being flinged and user touches, stop the fling. isFinished
			 * will be false if being flinged.
			 */
			if (!mScroller.isFinished()) {
				mScroller.abortAnimation();
			}

			// Remember where the motion event started
			mOriMotionX = x;
			mOriMotionY = y;
			mLastMotionX = x;
			mLastMotionY = y;
			mTimeDown = System.currentTimeMillis();
			mLastDownX = x;
			return true;
		case MotionEvent.ACTION_MOVE:
			//如果是往后滑动,屏幕向前,那么mLastMotionX是比x大的,deltaX是正的
			int deltaX = (int) (mLastMotionX - x);
			int deltaY = (int) (mLastMotionY - y);

			// final int moveX = (int) (mOriMotionX - x);
			final int moveY = (int) (mOriMotionY - y);
			mLastMotionX = x;
			mLastMotionY = y;
			//X方向的移动更多
			if (Math.abs(deltaY) < Math.abs(deltaX)) {
				//虽然X方向移动更多,但由于已经判定为上下滑动,所以只能return true,做这种情况左右不能滑动
				if (mFlagLimitUp) {
					return true;
				}

				final int buffer = getWidth() / 2;
				if (deltaX < 0) {
						if (deltaX < -MOVEY_NUM_X) {
							//mFlagLimitMove代表X方向确认在滑动了
							mFlagLimitMove = true;
						}
						
						if (mCurrentScreen == 0 && !mExecuteWhileSnapOut) {
							System.out.println("=====deltaX="+deltaX);
						    deltaX = getSlowDownDelta(deltaX);
						    System.out.println("=====after deltaX="+deltaX);
						}
						
						System.out.println("====mScrollX="+mScrollX+"buffer="+buffer+"deltaX="+deltaX+"x="+(Math.max(-mScrollX - buffer, deltaX)));
						scrollBy(Math.max(-mScrollX - buffer, deltaX), 0);
//					}
				} else if (deltaX > 0) {
					int availableToScroll = 0;
					
					if (getChildCount() > 0) { //此时Workspace上可能未加任何item,count == 0
					    availableToScroll = getChildAt(
			                            getChildCount() - 1).getRight()
			                            - mScrollX - getWidth();
					}
					
						if (deltaX > MOVEY_NUM_X) {
							mFlagLimitMove = true;
						}
						
						if (mCurrentScreen == getChildCount() - 1 && !mExecuteWhileSnapOut) {
                            deltaX = getSlowDownDelta(deltaX);
                        }
						
						System.out.println("====availableToScroll="+availableToScroll+"deltaX="+deltaX);
						scrollBy(Math.min(availableToScroll + buffer, deltaX), 0);

				}
			} else {

				if (mFlagLimitMove || mFlagLimitUp) {
