通过平滑的动画滑动活动

Question

我正在尝试解决这个问题...

结构是 -

[1]<---->[2]<-------->[3]<-------->[4]

其中[] =活动...（需要滑动视图的需要平滑动画）
我不需要的----->眨眼和向后堆栈，然后在Android设备上按...

活动1的1次刷2，再刷3，但它给出了眨眼而不是滑动...

这是代码...

  public ActivitySwipeDetector(SwipeInterface activity){
    this.activity = activity;
}
public void onRightToLeftSwipe(View v){
    Log.i(logTag, "RightToLeftSwipe!");
    activity.right2left(v);
}
public void onLeftToRightSwipe(View v){
    Log.i(logTag, "LeftToRightSwipe!");
    activity.left2right(v);
}
public void onTopToBottomSwipe(View v){
    Log.i(logTag, "onTopToBottomSwipe!");
    activity.top2bottom(v);
}
public void onBottomToTopSwipe(View v){
    Log.i(logTag, "onBottomToTopSwipe!");
    activity.bottom2top(v);
}
public boolean onTouch(View v, MotionEvent event) {
    switch(event.getAction()){
    case MotionEvent.ACTION_DOWN: {
        downX = event.getX();
        downY = event.getY();
        return true;
    }
    case MotionEvent.ACTION_UP: {
        upX = event.getX();
        upY = event.getY();
        float deltaX = downX - upX;
        float deltaY = downY - upY;
        // swipe horizontal?
        if(Math.abs(deltaX) > MIN_DISTANCE){
            // left or right
            if(deltaX < 0) { this.onLeftToRightSwipe(v); return true; }
            if(deltaX > 0) { this.onRightToLeftSwipe(v); return true; }
        }
        else {
            Log.i(logTag, "Swipe was only " + Math.abs(deltaX) + " long, need at least " + MIN_DISTANCE);
        }
        // swipe vertical?
        if(Math.abs(deltaY) > MIN_DISTANCE){
            // top or down
            if(deltaY < 0) { this.onTopToBottomSwipe(v); return true; }
            if(deltaY > 0) { this.onBottomToTopSwipe(v); return true; }
        }
        else {
            Log.i(logTag, "Swipe was only " + Math.abs(deltaX) + " long, need at least       " + MIN_DISTANCE);
            v.performClick();
        }
    }
    }
      return false;
  }
}

我建议您使用片段而不是活动。您想要的是通过ViewPager轻松完成的。我第一次使用ViewPager时使用了本教程：

希望这会有所帮助！
