查看了下网上关于TextView加载带图片标签的Html解决方案若干，发现很多都是讲下面这种：1：重写ImageGetter，直接获取网络图片(这是比较通用的做法，但是遇到大图片或者网络不好的情况下，会阻塞主进程)
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(), ""); //获取网路图片
} catch (Exception e) {
return null;
}
drawable.setBounds(0, 0, drawable.getIntrinsicWidth(), drawable.getIntrinsicHeight());
return drawable;
}
};
并设置TextView
TextView notice_content = (TextView) findViewById(R.id.notice_content);
notice_content.setText(Html.fromHtml(getIntent().getStringExtra(CONTENT),imgGetter,null));
2：重写ImageGetter，异步加载图片（这是比较流畅的方法，设置一个默认图片，异步加载出来，如果使用Drawable作为对象接收图片，手机会自动缩放图片，这不是我想要的，我需要的是真实大小图片（图片大于手机分辨率等比例缩放））

URLDrawable类
import android.graphics.Canvas;
import android.graphics.drawable.BitmapDrawable;
import android.graphics.drawable.Drawable;
public class URLDrawable extends BitmapDrawable {
protected Drawable drawable;
@Override
public void draw(Canvas canvas) {
if (drawable != null) {
drawable.draw(canvas);
}
}
}
此是解决方案中的部分，如果有好的解决方案，请粘贴出来，让我参考 研究！谢谢
