使用吐司配BufferedReader

Question

我希望你能提供幫助。

基本上我想發送什麼「BufferedReader」讀到一個吐司，但我從來沒有用過吐司之前，似乎無法讓我的頭圍繞它。

正如您在下面看到的，BufferedReader是「In」。

在此先感謝。

代碼：

    try { 
     new AsyncAction().execute(); 
    } catch(Exception e) { 
     e.printStackTrace();

      in = new BufferedReader(new InputStreamReader(socket.getInputStream()));

     } catch (IOException e) { 
      e.printStackTrace(); 
     } 

     return null;//returns what you want to pass to the onPostExecute() 
    } 

    protected void onPostExecute(String result) { 

     //results the data returned from doInbackground 

     IPControl.this.data = result; 

    } 
}

    if(msg.indexOf("SNX_COM> ") != -1) return msg.substring(0, msg.indexOf("SNX_COM> ")); 
    else if(msg.indexOf("SCX_COM> ") != -1) return msg.substring(0, msg.indexOf("SCX_COM> ")); 
    else return msg; 
} 
}

吐司只顯示與

Toast.makeText(context, message to display, Toast.LENGTH_SHORT).show();

在屏幕上的消息在你IPControl活動，把這個地方就像你onCreate，你會看到什麼吐司

Toast.makeText(IPControl.this, "Thanks for stopping by!", Toast.LENGTH_LONG).show();

在onPostExecute()嘗試

Toast.makeText(IPControl.this, result, Toast.LENGTH_LONG).show();
