这一行：

public class AccelerometerActivity extends Activity implements SensorEventListener {
private SensorManager sensorManager;
private Sensor accelerometer;

Bitmap mBitmap1;

// AnimatedView animatedView = null;
//ShapeDrawable mDrawable = new ShapeDrawable();

//ProgressDialog pd;

    Display display = getWindowManager().getDefaultDisplay();
    Point size = new Point();
    display.getSize(size);
    screenWidth = size.x;
    screenHeight=size.y;
    sensorManager = (SensorManager) getSystemService(SENSOR_SERVICE);
    accelerometer = sensorManager
            .getDefaultSensor(Sensor.TYPE_ACCELEROMETER);
    lastUpdate = System.currentTimeMillis();

}

@Override

            }


    }
}

public class DownloadImageTask extends AsyncTask<String, Void, Bitmap> {
    ImageView bmImage;

    public DownloadImageTask(ImageView bmImage) {
        this.bmImage = bmImage;
    }

    @Override
    protected void onPreExecute() {
        // TODO Auto-generated method stub
        super.onPreExecute();
        progressDialog.show();

        //pd.show();
    }

    protected Bitmap doInBackground(String... urls) {
        String urldisplay = urls[0];
        Bitmap mIcon11 = null;
        try {
            InputStream in = new java.net.URL(urldisplay).openStream();
            mBitmap1 = BitmapFactory.decodeStream(in);
            //b=mBitmap1.getWidth();

        } catch (Exception e) {
            Log.e("Error", e.getMessage());
            e.printStackTrace();
        }
        return mBitmap1;
    }

    @Override
    protected void onPostExecute(Bitmap result) {
        super.onPostExecute(result);
        //pd.dismiss();

        progressDialog.dismiss();

    }
}
}

应该是这个

HttpPostedFileBase file = Request.Files["vendorsEditUploadCertBlockName" + cr];
if (file.ContentLength > 0) {
    var fileName = Path.GetFileName(file.FileName);
    file.SaveAs("~/App_Data/uploads/certifications/" + insertCert.CERTIFICATION_ID + "/" + fileName);
}

使用Library Ext.all.debug.js而不是ext.base.js。

我的代码下面有什么问题，我没有得到输出
