交替使用Android服務

Question

內的窗口，我想用下面的代碼以關閉按鈕回來，我從https://stackoverflow.com/a/4937448/1218762得到

final Window win = getWindow(); 
final WindowManager.LayoutParams winParams = win.getAttributes(); 
winParams.flags |= WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON; 

//set screen brightness to the lowest possible 
winParams.screenBrightness = 0.01f; 

if (Build.VERSION.SDK_INT < 8) { 
    // hack for pre-froyo to set buttonBrightness off 
    try { 
     Field buttonBrightness = winParams.getClass().getField(
      "buttonBrightness"); 
     buttonBrightness.set(winParams, 0); 
    } catch (Exception e) { 
     e.printStackTrace(); 
    } 
} else { 
winParams.buttonBrightness = 0; 
} 
win.setAttributes(winParams); 

參考：訪問 Night Mode在這裏你就可以在服務關閉按鈕亮起，我知道服務沒有窗口，但它怎麼可能？

謝謝。

其中一個簡單的方法，我建議你是從你的Service廣播某種關斷消息到您的Activity並執行內部的BroadcastReceiver的onReceive方法所需的操作。
