//在onCreate中进行注册homeKeyEventBroadCastReceiver = new HomeKeyEventBroadCastReceiver(); registerReceiver(homeKeyEventBroadCastReceiver, new IntentFilter(Intent.ACTION_CLOSE_SYSTEM_DIALOGS));

//在onDestroy中销毁unregisterReceiver(homeKeyEventBroadCastReceiver);

public class HomeKeyEventBroadCastReceiver extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) { String action = intent.getAction(); if(action.equals(Intent.ACTION_CLOSE_SYSTEM_DIALOGS)){ Log.i("home", "点击了home键"); } }}
