Android 仿微博 网页链接的效果

[代码]java代码：

package com.linktextdemo;

import android.content.Intent;

import android.graphics.Color;

import android.graphics.drawable.Drawable;

import android.os.Bundle;

import android.support.v7.app.AppCompatActivity;

import android.text.SpannableString;

import android.text.Spanned;

import android.text.TextPaint;

import android.text.method.LinkMovementMethod;

import android.text.style.ClickableSpan;

import android.text.style.ImageSpan;

import android.view.View;

import android.widget.TextView;

import java.util.HashMap;

import java.util.Map;

import java.util.regex.Matcher;

import java.util.regex.Pattern;

/**

 *  类似微博 将链接（[(http(s)://)]www.baidu.com） 替换成 网页链接

 *  实现思路

 *  1、找出字符串中的网址(Bug one: 我这里用了两个简单的正则，不能识别不正确的网址如：https://、www等 )

 *  2、将找出的网址替换成 图片(ic_link)+网址链接，并设置网址链接的颜色和点击事件
