誰能告訴我爲什麼即使我從服務器獲取它的位圖也沒有創建?我看了至少15個這樣的問題,發現每一樣東西都差不多,但仍然無法找到解決方案。請嘗試一下你自己如果你可以。URL也給出。 程序中沒有錯誤。 由於位圖沒有創建
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://ademoproject.appspot.com/retrievedetails");
List<NameValuePair> list = new ArrayList<NameValuePair>();
list.add(new BasicNameValuePair("username",username));
UrlEncodedFormEntity urlencodedformentity = new UrlEncodedFormEntity(list);
httppost.setEntity(urlencodedformentity);
HttpResponse response = httpclient.execute(httppost);
BufferedReader br = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
Toast.makeText(this,br.readLine(), Toast.LENGTH_LONG).show();
byte []image=Base64.decode(br.readLine(), Base64.DEFAULT);
Bitmap bm = BitmapFactory.decodeByteArray(image, 0, image.length);
img.setImageBitmap(bm);
