如何监听home键

大家可能或多或少在开发过程中遇到过监听HOME键的需求，但是使出了浑身解数也不一定能够监听到，当然除开系统开发的童鞋哈，下面给大家介绍的方法我在项目中已经测试过了，是可行的，方法就是利用广播来实现。代码如下:

class HomeKeyEventBroadCastReceiver extends BroadcastReceiver {  
   static final String SYSTEM_REASON = "reason";  
   static final String SYSTEM_HOME_KEY = "homekey";//home key  
   static final String SYSTEM_RECENT_APPS = "recentapps";//long home key  

   @Override  

    public void onReceive(Context context, Intent intent) {  

    String action = intent.getAction();  

    if (action.equals(Intent.ACTION_CLOSE_SYSTEM_DIALOGS)) {  

    String reason = intent.getStringExtra(SYSTEM_REASON);  

    if (reason != null) {  

    if (reason.equals(SYSTEM_HOME_KEY)) {  

    // home key处理点  

  

    } else if (reason.equals(SYSTEM_RECENT_APPS)) {  

    // long home key处理点  

    }  

    }  

    }  

   }  

}  

然后当然需要在onCreate里面注册该广播：

receiver = new HomeKeyEventBroadCastReceiver();  

registerReceiver(receiver, new IntentFilter(Intent.ACTION_CLOSE_SYSTEM_DIALOGS));  

也需要在onDestroy里面解除该广播哦！
