使用处理程序结束进度对话框

Question

我需要知道如何在 http post 完成后关闭进度对话框。

这是我到目前为止所拥有的：

httppost.setEntity(me);

 HttpResponse responsePOST = client.execute(httppost);  
 HttpEntity resEntity = responsePOST.getEntity(); 

 InputStream inputstream = resEntity.getContent();
 BufferedReader buffered = new BufferedReader(new InputStreamReader(inputstream));
 StringBuilder stringbuilder = new StringBuilder();
 String currentline = null; 

 while ((currentline = buffered.readLine()) != null)
    { 
     stringbuilder.append(currentline + "\n"); 
     String result = stringbuilder.toString(); 
     Log.v("HTTP UPLOAD REQUEST",result); 
     inputstream.close();  
     handler.sendMessage(handler.obtainMessage());}
      }
     catch (Exception e) {
     e.printStackTrace();
     Toast.makeText(share.this, "Upload failed", Toast.LENGTH_SHORT).show();
    }
    }

    });

    background.start();
    }

    Handler handler = new Handler (){
    public void HandleMessage (Message msg){
    dialog.dismiss();
    }
    };

它不起作用，我应该在发送消息处理程序中放入什么来告诉处理程序关闭？提前感谢

尝试这样

HttpResponse responsePOST = client.execute(httppost);  
 HttpEntity resEntity = responsePOST.getEntity(); 

 InputStream inputstream = resEntity.getContent();
 BufferedReader buffered = new BufferedReader(new InputStreamReader(inputstream));
 StringBuilder stringbuilder = new StringBuilder();
 String currentline = null; 

 while ((currentline = buffered.readLine()) != null)
    { 
     stringbuilder.append(currentline + "\n"); 
     String result = stringbuilder.toString(); 
     Log.v("HTTP UPLOAD REQUEST",result); 
     inputstream.close();  
     //handler.sendMessage(handler.obtainMessage());}
      }
     catch (Exception e) {
     e.printStackTrace();
     Toast.makeText(share.this, "Upload failed", Toast.LENGTH_SHORT).show();
    }
     Message msg = Message.obtainMessage();
     msg.arg1 = 1;
     handler.sendMessage(msg);

    }

    });

    background.start();
    }

    private final Handler handler = new Handler (){
    public void HandleMessage (Message msg){
         if(msg.arg1 == 1)
               dialog.dismiss();
    }
    };
