Android(安卓)远程回调

1.点击button 发送Handler1 Message 收到消息开启线程进行处理

2.收到消息后调用已经绑定的 mService 的 mService.sendMail（）方法

mService.sendMailAlarm(SEND_MAIL_TYPE,subject,body.toString()); --Activity类

Service类

private final IRemoteService.Stub mBinder = new IRemoteService.Stub() {

public void sendMail(int type, String subjectText, String sendText)
throws RemoteException {
Constant.Log("sendMailAlarm", "RunKKKKKK");
new SendMailAlarmMsgThread(type, subjectText, sendText).start();
}

｝

】

3 。SendMailAlarmMsgThread 处理完发送 Service Handler2 消息

4. 处理接受到的信息后回调函数调用

Service类

private final RemoteCallbackList<IRemoteServiceCallback> mCallbacks = new RemoteCallbackList<IRemoteServiceCallback>();

private void _makeSendMailResultCallbacksWork(int result) {
Constant.Log("RemoteService", "_makeSendMailResultCallbacksWork");
// Broadcast to all clients the new value.
Constant.Log("onSendMailReturn", "RunKKKKKK");
try {
final int N = mCallbacks.beginBroadcast();
for (int i = 0; i < N; i++) {
try {
mCallbacks.getBroadcastItem(i).onSendMailReturn (result);
} catch (RemoteException e) {
Constant.exception(e);
}
}
mCallbacks.finishBroadcast();
} catch (Exception e) {
e.printStackTrace();
}
}

onSendMailReturn

在Activity 类中实现

  private IRemoteServiceCallback mCallback = new IRemoteServiceCallback.Stub() {             @Override        public void onSetPowerStatusReturn(String arg0, String arg1) throws RemoteException {            // TODO Auto-generated method stub        }        @Override        public void onSendMailReturn(int arg0) throws RemoteException {            // TODO Auto-generated method stub            LogOut("call method : onSendMailReturn()---" + arg0);            // if (!isClickMailBtn) return ;            // isClickMailBtn = false ;            switch (arg0) {                case 0:                    mHandler.removeMessages(MAIL_RECEIVE_SUCCESS_RESULT_ORDER);                    mHandler.sendEmptyMessage(MAIL_RECEIVE_SUCCESS_RESULT_ORDER);                    break;                case 1:                    mHandler.removeMessages(MAIL_RECEIVE_FAILURE_RESULT_ORDER);                    mHandler.sendEmptyMessage(MAIL_RECEIVE_FAILURE_RESULT_ORDER);                    break;                default:                    break;            }        }    };

处理完后发送Handler1 消息更新画面

耗时操作UI更行超过5秒！

本地服务和远程服务

Android 监听事件一旦监听一直会有守护线程监听。
