我正在尝试将捕获/选择的图像从图库上传到我的服务器，但出现以下错误

Question

 class ImageGalleryTask extends AsyncTask<Void, Void, String> {
    @SuppressWarnings("unused")
    @Override
    protected String doInBackground(Void... unsued) {
            InputStream is;
            BitmapFactory.Options bfo;
            Bitmap bitmapOrg;
            ByteArrayOutputStream bao ;
           // ImageView imgshoot = null;
            bfo = new BitmapFactory.Options();
            bfo.inSampleSize = 2;
           // bitmapOrg =   BitmapFactory.decodeFile(Environment.getExternalStorageDirectory() + "/" + customImage, bfo);
    //      bitmap = mark(bitmap, "Hallo");



            bao = new ByteArrayOutputStream();
            bitmap.compress(Bitmap.CompressFormat.PNG, 0, bao);
            byte [] ba = bao.toByteArray();
            Bitmap decoded = BitmapFactory.decodeStream(new ByteArrayInputStream(bao.toByteArray()));
            String ba1 = Base64.encodeBytes(ba);
            ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
            nameValuePairs.add(new BasicNameValuePair("image",ba1));
            nameValuePairs.add(new BasicNameValuePair("cmd","image_android"));
            Log.v("log_tag", System.currentTimeMillis()+".png");           
            try{
                    HttpClient httpclient = new DefaultHttpClient();
                    HttpPost httppost = new 
                  //  Here you need to put your server file address
                    HttpPost("http://192.168.0.1/Upload/UploadImg.php");
                    httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
                    HttpResponse response = httpclient.execute(httppost);
                    HttpEntity entity = response.getEntity();
                    is = entity.getContent();
                    Log.v("log_tag", "In the try Loop" );
               }catch(Exception e){
                    Log.v("log_tag", "Error in http connection "+e.toString());
               }
        return "Success";
        // (null);
    }

    @Override
    protected void onProgressUpdate(Void... unsued) {

    }

    @Override
    protected void onPostExecute(String sResponse) {
        try {
            if (dialog.isShowing())
                dialog.dismiss();
        } catch (Exception e) {
            Toast.makeText(getApplicationContext(),
                    e.getMessage(),
                    Toast.LENGTH_LONG).show();
            Log.e(e.getClass().getName(), e.getMessage(), e);
        }
    }

            imgView.setImageBitmap(bitmap);
}

这是 Logcat 中显示的错误：

02-16 14:44:05.872: E/AndroidRuntime(9375): java.lang.RuntimeException: An error occurred while executing doInBackground() 02-16 14:44:05.872: E/AndroidRuntime(9375): at

我什至添加了存储在 php 文件中的服务器代码：(check.php):

<?php
    $target_dir = "Upload/";
    $base=$_REQUEST['image'];
    $name=$_REQUEST['cmd'];
    $binary=base64_decode($base);
      header('Content-Type: jpeg; charset=utf-8');
   $file = fopen($target_path, 'wb');
   $file = fopen($name, 'wb');
   fwrite($file, $binary);
   fclose($file);
    //move_uploaded_file($file,$target_path.$name);
      copy($name,$target_path.$name);
     ?>

Answer 1

在doInBackground()中，你写了imgView.setImageBitmap(bitmap)这不是acceptable.You应该在那个方法中写后台操作。

有很多 tutorials.Hope 会有帮助的。试试这个 example

Answer 2

替换imgView.setImageBitmap(位图)；与

runOnUiThread(new Runnable() {

                    @Override
                    public void run() {
                        // TODO Auto-generated method stub
                        imgView.setImageBitmap(bitmap);
                    }
                });
