使用TextView显示网页中的图片

Html类下有一个ImageGetter接口可以帮助我们完成，直接上代码：

MainActivity：

package com.home.testhtml;

import java.io.IOException;
import java.net.MalformedURLException;
import java.net.URL;

import android.app.Activity;
import android.graphics.drawable.Drawable;
import android.os.Bundle;
import android.os.Handler;
import android.os.Message;
import android.text.Html;
import android.text.Html.ImageGetter;
import android.text.Spanned;
import android.widget.TextView;

public class MainActivity extends Activity {
	private TextView tv;
	private String htmlStr = "<h1>测试html的img标签</h1><p font='red'>这里是测试内容</p><p><img src='http://avatar.profile.csdn.net/A/E/5/2_piaopiaohu123.jpg'></p>";
	private Handler mHandler = new Handler() {
		public void handleMessage(Message msg) {
			Spanned sp = (Spanned) msg.obj;
			tv.setText(sp);
		};
	};

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		tv = new TextView(this);
		setContentView(tv);
		new Thread() {
			public void run() {
				Spanned sp = Html.fromHtml(htmlStr, new MyImageGetter(), null);
				Message msg = new Message();
				msg.obj = sp;
				mHandler.sendMessage(msg);
			};
		}.start();
	}

	class MyImageGetter implements ImageGetter {

		@Override
		public Drawable getDrawable(String source) {
			Drawable mDrawable = null;
			try {
				mDrawable = Drawable.createFromStream(
						new URL(source).openStream(), "test.jpg");
				mDrawable.setBounds(0, 0, mDrawable.getIntrinsicWidth(),
						mDrawable.getIntrinsicHeight());
			} catch (MalformedURLException e) {
				e.printStackTrace();
			} catch (IOException e) {
				e.printStackTrace();
			}
			return mDrawable;
		}

	}
}
