    if (mysql_num_rows($result) > 0) { 

     $result = mysql_fetch_array($result); 

     $user = array(); 
     $user["image"] = base64_encode($result["image"]); 
     $response["success"] = 1; 
     $response["image_table"] = array(); 

     array_push($response["image_table"], $user); 
     echo json_encode($response); 
    } else {

quand je l'utilise dans ma classe imageview dosent montrent mon image .... et l'activité asynctask continue en cours d'exécution ......

class LoadImage extends AsyncTask<String, String, String> { 
    @Override 
    protected void onPreExecute() { 
     super.onPreExecute(); 
     pDialog = new ProgressDialog(MainActivityMap.this); 
     pDialog.setMessage("Loading Image. Please wait..."); 
     pDialog.setIndeterminate(false); 
     pDialog.setCancelable(false); 
     pDialog.show(); 
    } 
    protected String doInBackground(String... args) { 
      List<NameValuePair> params = new ArrayList<NameValuePair>(); 
      params.add(new BasicNameValuePair("username", email)); 
      json= jsonParser.makeHttpRequest(url_img_address, "GET", params); 

      Log.d("Image: ", json.toString()); 

      try { 
       int success = json.getInt(TAG_SUCCESS); 

       if (success == 1) { 
        address = json.getJSONArray(TAG_IMAGE_TABLE); 
        for (int i = 0; i < address.length(); i++) { 
         JSONObject c = address.getJSONObject(i); 
         image = c.getString(TAG_IMAGE); 
         InputStream stream = new ByteArrayInputStream(Base64.decode(image.getBytes(), Base64.DEFAULT)); 
         bmp=BitmapFactory.decodeStream(stream); 


        } 
       } else { 

       } 
      } catch (JSONException e) {

quel est le problème et comment le résoudre ...... thx à l'avance

Answer 1

Essayez ceci,

String strPicture; 
for (int i = 0; i < address.length(); i++) { 
JSONObject c = address.getJSONObject(i); 
strPicture= c.getString(TAG_IMAGE); 
byte bytePic[] = null; 
     try { 
      bytePic = Base64.decode(strPicture, Base64.DEFAULT); 
     } catch (Exception e) { 
      e.printStackTrace(); 
     } 

     if (bytePic != null) { 
      ByteArrayInputStream imageStream = new ByteArrayInputStream(
        bytePic); 
      Bitmap theImage = BitmapFactory.decodeStream(imageStream); 
      imageStream.reset(); 
      imageView.setImageBitmap(theImage); //Setting image to the image view 
     } 
}
