我正在尝试使用以下代码从Android服务器获取图像（15张图像）。

使用以下代码调用AsynTask：

DownloadImageSequencially lmib = new DownloadImageSequencially（）; Lmib.execute（SplitImages）;

此处 SplitImages 是图片网址数组。 

class DownloadImageSequencially extends AsyncTask<Object,Void,Void>
{

    @Override
    protected Void doInBackground(Object... param) {
        // TODO Auto-generated method stub

            for (int indx = 0; indx < SplitImages.length; indx++) {
                 downloadBitmap(SplitImages[indx],indx);
            }
        return null;
    }

    @Override
    protected void onPostExecute(Void result) {
        Log.i("Async-Example", "onPostExecute Called");

            progressDialog.dismiss();
            defailtReviewCardInitialisation();
            reviewCardActions();
    }

    private void downloadBitmap(String url,int indx) {
        // initilize the default HTTP client object

        HttpClient client = new DefaultHttpClient();

        //forming a HttoGet request
        url = url.replace("\\","");
        url = url.replace("\"","");
        Log.e("url","url: "+url);
        final HttpGet getRequest = new HttpGet(url);
        Log.e("Masthan1","Masthan1");
        //HttpPost getRequest = new HttpPost(url);
        try {

            if (android.os.Build.VERSION.SDK_INT > 9) {
                StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
                StrictMode.setThreadPolicy(policy);
            }
            Log.e("Masthan2","Masthan2");
            HttpResponse response = client.execute(getRequest);
            Log.e("Masthan3","Masthan3");
            //check 200 OK for success
            final int statusCode = response.getStatusLine().getStatusCode();
            Log.e("Masthan4","Masthan4");
            if (statusCode != HttpStatus.SC_OK) {
                Log.w("ImageDownloader", "Error " + statusCode +
                        " while retrieving bitmap from " + url);

            }

            final HttpEntity entity = response.getEntity();
            Log.e("Masthan5","Masthan5");
            if (entity != null) {
                InputStream inputStream = null;
                try {
                    // getting contents from the stream
                    inputStream = entity.getContent();
                    Log.e("Masthan6","Masthan6");
                    // decoding stream data back into image Bitmap that android understands
                    bitmapArray[indx] =  BitmapFactory.decodeStream(inputStream);
                    Log.e("Masthan7","Masthan7");

                } finally {
                    Log.e("Masthan8","Masthan8");
                    if (inputStream != null) {
                        Log.e("Masthan9","Masthan9");
                        inputStream.close();
                        Log.e("Masthan10", "Masthan10");
                    }
                    entity.consumeContent();
                    Log.e("Masthan11", "Masthan11");
                }
            }
        } catch (Exception e) {
            // You Could provide a more explicit error message for IOException
            getRequest.abort();
            Log.e("ImageDownloader", "Something went wrong while" +
                    " retrieving bitmap from " + url + e.toString());
        }

    }
}

这是Android的logcat。

我观察到的是，当我们尝试在AsynTask中执行以下操作时，即使我在高速互联网或本地主机上工作，也需要花费大量时间（至少30秒）。

  1. Client.execute（调用getRequest）;
  2. Entity.getContent（）;

    3. 请帮帮我，为什么需要时间？如果表现良好，你也可以建议我替代方法。

1 个答案:

答案 0 :(得分：0)

你正在使用单个asynctask线程下载多个文件..所以显然，如果文件数量很高，则需要更多时间..如果你想同时下载多个文件，那么尝试使用

http://download.oracle.com/javase/6/docs/api/java/util/concurrent/ExecutorService.html

请参阅： - java download multiple files using threads
