android 中使用ImageGetter在TextView中显示网络图片

今天在做项目的时候,接口返回的信息是html格式的,一开始我是用textView.setText(Html.fromHtml("html标签字符串",null,null));但是发现html标签里有img标签,里面还有一个图片的链接url,如下所示:
<img title="058B4D41236B9980FC1C07C9EC49872E.png" src="http://www.hbxyjob.cn/cmsfiles/1/image/public/201708/20170824093509_2avfad9vwc.png"/>
尼玛,这怎么显示呢?于是在网上找了很久资料,改了一下代码,实现的效果如下:

HtmlGetter.gif
1、思路分析
  • 主要是用Html.ImageGetter来实现

  • 接口返回的html字段中,有可能包含多个网络图片的地址,这时候需要下载图片到本地。

  • 第一次显示的时候只是把文字部分加载出来,等到图片加载完成的时候,再一次赋值给Textview就实现了上面动图的效果。

}
3、核心代码1分析:设置TextView可点击跳转Html里面的链接
    //保存文件路径
    private final String path = Environment.getExternalStorageDirectory().getAbsolutePath()+"/htmlimg/";
        //设置链接中标签是可以点击并且可以跳转到浏览器打开的
        tvJobDes.setClickable(true);
        tvJobDes.setMovementMethod(LinkMovementMethod.getInstance());
        //整个TextView居中显示
//      tvJobDes.setGravity(Gravity.CENTER_HORIZONTAL);

4、核心代码2分析:第一次赋值给 TextView,同时开始下载图片
private void setData() {
        //初始化下载类
        downLoadUtils=new DownLoadHtmlImageUtils();
        //设置下载类监听事件
        downLoadUtils.setOnDownloadListener(onDownloadListener);
        //给Textview赋值
        tvJobDes.setText(Html.fromHtml(mFvalue,imageGetter,null));
    }
    Drawable drawable = null;
    Bitmap bitmap = null;
    Html.ImageGetter imageGetter = new Html.ImageGetter() {
        public Drawable getDrawable(String source) {

            String fileString=path+String.valueOf(source.hashCode());
            Log.i("DEBUG", fileString+"");
            Log.i("DEBUG", source+"");

            if (!new File(path).exists()){
                new File(path).mkdirs();
                LogUtils.d(TAG,"创建文件夹成功========");
            }
            //判断SD卡里面是否存在图片文件
            if (new File(fileString).exists()) {
                Log.i("DEBUG", fileString+"  eixts");
                //获取本地文件返回Drawable
                bitmap = BitmapFactory.decodeFile(fileString);
                drawable = new BitmapDrawable(bitmap);
//              drawable=Drawable.createFromPath(fileString);
                //设置图片边界
                if (drawable != null){
                    drawable.setBounds(0, 0, drawable.getIntrinsicWidth(), drawable.getIntrinsicHeight());
                    return drawable;
                }
                return null;

            }else {
                Log.i("DEBUG", fileString+" Do not eixts");
                //启动新线程下载
                downLoadUtils.download(source, path+String.valueOf(source.hashCode()));
                return drawable;
            }

        };

    };
5、核心代码3分析:等待图片下载完成的时候,再一次赋值给TextView
DownLoadHtmlImageUtils.OnDownloadListener onDownloadListener=new DownLoadHtmlImageUtils.OnDownloadListener() {

        //下载进度
        public void onDownloadUpdate(DownLoadHtmlImageUtils manager, int percent) {
            // TODO Auto-generated method stub
            Log.i("DEBUG", percent+"");
        }

        //下载失败
        public void onDownloadError(DownLoadHtmlImageUtils manager, Exception e) {
            // TODO Auto-generated method stub

        }

        //开始下载
        public void onDownloadConnect(DownLoadHtmlImageUtils manager) {
            // TODO Auto-generated method stub
            Log.i("DEBUG", "Start  //////");
        }

        //完成下载
        public void onDownloadComplete(DownLoadHtmlImageUtils manager, Object result) {
            // TODO Auto-generated method stub
            Log.i("DEBUG", result.toString());
            //替换sTExt的值,就是把图片的网络路径换成本地SD卡图片路径(最早想法,可以不需要这样做了)
            //sText.replace(result.toString(), path+String.valueOf(result.hashCode()));
            //再一次赋值给Textview
            tvJobDes.setText(Html.fromHtml(mFvalue, imageGetter, null));
        }
    };
6、核心代码4分析:退出Activity或者Fragment的时候,回收Bitmap
@Override
    protected void onDestroy() {
        super.onDestroy();
        drawable = null;

//因为本应用要下载图片太多,所以每次退出的时候把下载好的本地图片删除
        FileUtils.delDir(path);
        if (bitmap != null && !bitmap.isRecycled()){
            bitmap.recycle();
            bitmap = null;
            drawable = null;
        }

        if (imageGetter != null){
            imageGetter = null;
        }
    }
8、FileUtils工具类核心方法:为了删除下载好的本地图片
 /**
     * 删除方法 这里只会删除某个文件夹下的文件<br/>
     * 支持两级目录删除
     */
    public static void delDir(String path) {
            File directory = new File(path);
            if (directory != null && directory.exists() && directory.isDirectory()) {
                for (File item : directory.listFiles()) {
                    if (item.isDirectory()) {
                        for (File img : item.listFiles()) {
                            img.delete();
                        }
                    }
                    item.delete();
                }
            }
    }

11、存在的问题
  • 当接口返回里面包含很多<img>标签,也就是说要加载很多张图片,或许这些图片都是大图,那么如何做到更好的缓存呢?我尝试过先判断本地有没有对应的图片,没有的话就去下载,有的话沿用本地图片,不过还是会报内存溢出。(这里我没有对图片进行压缩,因为我看到下载的图片都是几十kb或者100多kb)
  • <p style="TEXT-ALIGN: center> 图片居中的标签不起作用,居中不了

哪位大神有知道如何实现的,麻烦告知下
