它们的定义android滑动菜单

在这里实现了两个滑动菜单效果，的拖放内容的第一部分，菜单拖出像这样的效果感觉，另一种是拖动内容。后面的内容固定菜单。我感觉有层次感的效果，如下面

第一种效果的代码实现例如以下：

package com.tenghu.customsideslip.menu.view;

import android.content.Context;
import android.os.AsyncTask;
import android.util.AttributeSet;
import android.util.DisplayMetrics;
import android.view.MotionEvent;
import android.view.VelocityTracker;
import android.view.View;
import android.view.WindowManager;
import android.widget.LinearLayout;
