以广播接收器的数据传输

以广播接收器的数据传输

本文介绍了获取GPS定位在一个广播接收器/或服务,以广播接收器的数据传输的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

我是新来的机器人。
我想获得GPS定位在一个广播接收器,但它显示了一个错误。

我的code是:

 公共无效的onReceive(上下文的背景下,意图意图){
    LocationManager locManager =(LocationManager)
            getSystemService(Context.LOCATION_SERVICE);
    在getSystemService方法//错误
    LocationListener的locListener =新MyLocationListener();
    locManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,0,0,
            locListener);
    位置LOC = locManager
            .getLastKnownLocation(LocationManager.GPS_PROVIDER);
    Log.d(** **的位置,位置+ loc.getLatitude());
}
 

问题:

  1. 是否有可能获得GPS定位数据广播接收器?
  2. 我那么另一种替代方式远是使用它是由广播接收器调用的服务。该服务可以获取GPS数据,但我怎样才能得到它在广播接收器?
解决方案

从BroadcastReceiver的我无法启动位置管理为好。于是,我开始了服务上的BroadcastReceiver,并在该服务中我操纵的位置管理。我想我找到这个解决方案在Android开发文档。您也可以启动,而不是服务活动。

下面是切换到服务上的BroadcastReceiver的code:

的onReceive 写这个方法

 意图serviceIntent =新的意图(背景下,MyService.class);
    serviceIntent.putExtra(locateRequest,locateRequest); //如果你想传递参数,从这里服务
    serviceIntent.putExtra(queryDeviceNumber,结果[1]);
    context.startService(serviceIntent); //开始为GET位置服务
 

I am new to android.
I want to get GPS Location in a broadcast receiver but it shows an error.

My code is :

public void onReceive(Context context, Intent intent) {
    LocationManager locManager = (LocationManager)
            getSystemService(Context.LOCATION_SERVICE);
    // errors in getSystemService method
    LocationListener locListener = new MyLocationListener();
    locManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0,
            locListener);
    Location loc = locManager
            .getLastKnownLocation(LocationManager.GPS_PROVIDER);
    Log.d(" **location**", " location" + loc.getLatitude());
}

Questions :

  1. Is it possible to get GPS Location data in Broadcast receiver?
  2. Another alternative way I tried so far was to use a service which is invoked by the Broadcast receiver. The service can get GPS data, but how can I get it in the Broadcast receiver?
解决方案

From BroadcastReceiver I could not start Location Manager as well. So I started a service on BroadcastReceiver and in that service I manipulated Location Manager. I think I found this solution in Android development documentation. You also can start Activity instead of Service.

Here is the code of switch to Service on BroadcastReceiver:

write this in onReceive method

    Intent serviceIntent = new Intent(context,MyService.class);
    serviceIntent.putExtra("locateRequest", "locateRequest"); // if you want pass parameter from here to service
    serviceIntent.putExtra("queryDeviceNumber", results[1]);
    context.startService(serviceIntent); //start service for get location
