自定义android侧滑菜单

标签：侧滑菜单

这里实现两种侧滑菜单效果，第一种拖拽内容部分，菜单像是被拖出来的感觉的这种效果，第二种是拖拽内容部分，菜单在内容后面不动，感觉有一种层次感的效果，如下

第一种效果的代码实现如下：

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;
