TextView載入帶圖片的Html解決方案

查看了下網上關於TextView載入帶圖片標籤的Html解決方案若干，發現很多都是講下面這種：
1：重寫ImageGetter，直接擷取網狀圖片(這是比較通用的做法，但是遇到大圖片或者網路不好的情況下，會阻塞主進程)

ImageGetter imgGetter = new Html.ImageGetter() {        public Drawable getDrawable(String source) {              Drawable drawable = null;              URL url;                try {                     url = new URL(source);                    drawable = Drawable.createFromStream(url.openStream(), "");  //擷取網路圖片              } catch (Exception e) {                    return null;                }                drawable.setBounds(0, 0, drawable.getIntrinsicWidth(), drawable.getIntrinsicHeight());              return drawable;         }};

 並設定TextView

TextView notice_content = (TextView) findViewById(R.id.notice_content);notice_content.setText(Html.fromHtml(getIntent().getStringExtra(CONTENT),imgGetter,null));

2：重寫ImageGetter，非同步載入圖片（這是比較流暢的方法，設定一個預設圖片，非同步載入出來，如果使用Drawable作為對象接收圖片，手機會自動縮放圖片，這不是我想要的，我需要的是真實大小圖片（圖片大於手機解析度等比例縮放））

　　URLDrawable類

import android.graphics.Canvas;import android.graphics.drawable.BitmapDrawable;import android.graphics.drawable.Drawable;public class URLDrawable extends BitmapDrawable {protected Drawable drawable;@Overridepublic void draw(Canvas canvas) {    if (drawable != null) {   drawable.draw(canvas);  }}}
