如何更改pubnub中的togglebutton狀態訂閱回調

Question

我想在pubnub訂閱時收到成功回調時切換按鈕的狀態，如果消息等於預設字符串togglebutton.setchecked（true） 否則它將調用敬酒，並說連接問題 怎麼能這樣在異步過程中完成 UPDATE：

試圖亨利的建議後：

try { 
    pubnub.subscribe("reply", new Callback() { 
     public void successCallback(String channel, Object message) { 
      System.out.println(message); 

      //Match your String Here and set Toggle Btn status here 
      if(message.toString().equals("RL1:1")){ 
       //Set True 
       toggleButton1.setChecked(true); 
      } 
      toggleButton1.setBackgroundResource(R.drawable.light100); 
     } 

     public void errorCallback(String channel, PubnubError error) { 
      System.out.println(error.getErrorString()); 
     } 
    }); 
} 
catch (PubnubException e) { 
    e.printStackTrace(); 
}

我還沒有使用Pubnub但是你可以在你的代碼這樣做： 注：我假設，這個回調是在主線程

在你活動類：

private ToggleButton mBtnToggle; 

/* Subscribe to the demo_tutorial channel */ 
try { 
    pubnub.subscribe("demo_tutorial", new Callback() { 
     public void successCallback(String channel, Object message) { 
      System.out.println(message); 
      //Match your String Here and set Toggle Btn status here 
      if(message.str.equal(strData)){ 
       //Set True 
       mBtnToggle.setChecked(true) 
      } 
     } 

     public void errorCallback(String channel, PubnubError error) { 
      System.out.println(error.getErrorString()); 
     } 
    }); 
} 
catch (PubnubException e) { 
    e.printStackTrace(); 
}

這裏是工作代碼：

try { 
    pubnub.subscribe("reply", new Callback() { 
     public void successCallback(String channel, Object message) { 
      System.out.println(message); 
      msg = message.toString(); 
      //Match your String Here and set Toggle Btn status here 
      lighting.this.runOnUiThread(new Runnable(){ 
       @Override 
       public void run(){ 
        if(msg.equals("RL1:1")){ 
         //Set True 
         toggleButton1.setChecked(true); 
         toggleButton1.setBackgroundResource(R.drawable.light100); 
        } 
       } 
      }); 
     }; 

     public void errorCallback(String channel, PubnubError error) { 
      System.out.println(error.getErrorString()); 
     } 

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