java - 如何在 Android 中将此图像设置为 Activity

Question

我正在 Android 上使用异步下载文件，现在我希望此文件在 Activity 中显示。我如何在 onSucess 方法中执行此操作？我尝试了以下方法，但图像未显示!

AsyncHttpClient fileDownload = new AsyncHttpClient();
String[] allowedContentTypes = new String[] { "image/png", "image/jpeg" };
fileDownload.get("http://server.com/file.png", new BinaryHttpResponseHandler(allowedContentTypes)           {
       @Override
       public void onSuccess(byte[] fileData) {
        //Do Something here to view files in activity   
       ImageView img = (ImageView) findViewById (R.id.imageview1);   
}

Answer 1

试试这个代码

AsyncHttpClient fileDownload = new AsyncHttpClient();
String[] allowedContentTypes = new String[] { "image/png", "image/jpeg" };
fileDownload.get("http://server.com/file.png", new BinaryHttpResponseHandler(allowedContentTypes) {
       @Override
       public void onSuccess(byte[] fileData) {
        //Do Something here to view files in activity  
         Bitmap bmp=BitmapFactory.decodeByteArray(fileData,0,fileData.length); 
         ImageView img = (ImageView) findViewById (R.id.imageview1);
         img.setImageBitmap(bmp);
         }
