最后花了几个小时后,我找到了Base64图像的解决方案..我在这里发布了完整的解决方案..

原来我使用的答案作为参考只是this asnwer的副本..

URLDrawable.java

import android.graphics.Canvas;

import android.graphics.drawable.BitmapDrawable;

import android.graphics.drawable.Drawable;

public class URLDrawable extends BitmapDrawable {

// the drawable that you need to set, you could set the initial drawing

// with the loading image if you need to

protected Drawable drawable;

@Override

public void draw(Canvas canvas) {

// override the draw to facilitate refresh function later

if(drawable != null) {

drawable.draw(canvas);

}

}

}

URLImageParser.java

import java.io.InputStream;

import java.net.URL;

import android.content.Context;

import android.graphics.Bitmap;

import android.graphics.BitmapFactory;

import android.graphics.drawable.BitmapDrawable;

import android.graphics.drawable.Drawable;

import android.os.AsyncTask;

import android.text.Html.ImageGetter;

import android.util.Base64;

import android.view.View;

public class URLImageParser implements ImageGetter {

Context context;

View container;

public URLImageParser(View container, Context context) {

this.context = context;

this.container = container;

}

public Drawable getDrawable(String source) {

if(source.matches(“data:image.*base64.*”)) {

String base_64_source = source.replaceAll(“data:image.*base64”, “”);

byte[] data = Base64.decode(base_64_source, Base64.DEFAULT);

Bitmap bitmap = BitmapFactory.decodeByteArray(data, 0, data.length);

Drawable image = new BitmapDrawable(context.getResources(), bitmap);

image.setBounds(0, 0, 0 + image.getIntrinsicWidth(), 0 + image.getIntrinsicHeight());

return image;

} else {

URLDrawable urlDrawable = new URLDrawable();

ImageGetterAsyncTask asyncTask = new ImageGetterAsyncTask(urlDrawable);

asyncTask.execute(source);

return urlDrawable; //return reference to URLDrawable where We will change with actual image from the src tag

}

}

public class ImageGetterAsyncTask extends AsyncTask {

URLDrawable urlDrawable;

public ImageGetterAsyncTask(URLDrawable d) {

this.urlDrawable = d;

}

@Override

protected Drawable doInBackground(String… params) {

String source = params[0];

return fetchDrawable(source);

}

@Override

protected void onPostExecute(Drawable result) {

urlDrawable.setBounds(0, 0, 0 + result.getIntrinsicWidth(), 0 + result.getIntrinsicHeight()); //set the correct bound according to the result from HTTP call

urlDrawable.drawable = result; //change the reference of the current drawable to the result from the HTTP call

URLImageParser.this.container.invalidate(); //redraw the image by invalidating the container

}

public Drawable fetchDrawable(String urlString) {

try {

InputStream is = (InputStream) new URL(urlString).getContent();

Drawable drawable = Drawable.createFromStream(is, “src”);

drawable.setBounds(0, 0, 0 + drawable.getIntrinsicWidth(), 0 + drawable.getIntrinsicHeight());

return drawable;

} catch (Exception e) {

return null;

}

}

}

}

用法：

TextView comment_content_container = ((TextView)findViewById(R.id.comment_content));

comment_content_container.setText(Html.fromHtml(comment.content, new URLImageParser(comment_content_container, this), null));

如果有人知道Base64更好的正则表达式,请回复我会更新答案..
