仿360在Launcher画面显示内存使用率的浮窗(基础版)

MainActivity如下:

package cc.cc;

import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.app.Activity;
import android.content.Context;
import android.content.Intent;
/**
 *  Demo描述:
 *  仿360在Launcher画面显示内存使用率的浮窗.
 *  当然这里只是简单地仿O(∩_∩)O
 *
 *  思路整理:
 *  1 涉及到大小两个浮窗.并且两个浮窗之间有逻辑联系.比如:
 *    显示小浮窗时不显示大浮窗.所以利用DriftingWindowManager
 *    来管理这两个浮窗
 *  2 各用一个类来封装和实现两个浮窗的操作
 *  3 以上两个类均继承自Layout
 *
 *  总的来讲该示例还是比较简单的
 *
