advancedrecyclerview
advancedrecyclerview侧滑封装
advancedrecyclerview提供了很多强大的功能，但是相对的使用成本还是有点大，因为项目侧滑的样式基本都一样，故基于项目，封装了一下~~

}自定义控件相关
- 在处理控件移动时距离的限制
/**
* @param top
* @param dy 手指移动偏移量 上拉为正，下拉为负
* @param minValue 允许移动到的最小值
* @param maxValue 允许移动到的最大值
* @return
*/
public int getAreaValue(int top, int dy, int minValue, int maxValue) {
//不允许继续往上拉
if (top + dy < minValue) {
return minValue - top;
}
//不允许继续往下拉
if (top + dy > maxValue) {
return maxValue - top;
}
//返回正常的偏移量
return dy;
}2.根据触摸事件，返回是否点击当前view
/**
* 根据触摸事件，返回是否点击当前view
*
*
* @param view 需要判断的view
* @param event 触摸事件
* @return true 点击
*/
public boolean isClickView(View view, MotionEvent event) {
Rect rect = new Rect();
view.getHitRect(rect);
return rect.contains(((int) event.getX()), ((int) event.getY()) + getScrollY());
}
