有人知道如何在Android上检索GSM和CDMA上的手机信号塔列表.

我一直在尝试使用Google地图位置API:https: //developers.google.com/maps/documentation/business/geolocation/

我想通过这些字段获取手机信息塔的信息:

• cellId:单元的唯一标识符.在GSM上,这是小区ID(CID); CDMA网络使用基站ID(BID).
• locationAreaCode:GSM网络的位置区域代码(LAC); CDMA网络使用网络ID(NID).
• mobileCountryCode:手机信号塔的移动国家代码(MCC).
• mobileNetworkCode:手机信号塔的移动网络代码.这是用于GSM的MNC,或用于CDMA的系统ID(SID).
• age:自此单元格为主要数据以来的毫秒数.如果age为0,则cellId表示当前测量值.
• signalStrength:以dBm为单位测量的无线电信号强度.
• timingAdvance:时间提前值.

此代码并不特别获取单元塔信息.

TelephonyManager tel = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);

// Type of the network
int phoneTypeInt = tel.getPhoneType();
String phoneType = null;
phoneType = phoneTypeInt == TelephonyManager.PHONE_TYPE_GSM ? "gsm" : phoneType;
phoneType = phoneTypeInt == TelephonyManager.PHONE_TYPE_CDMA ? "cdma" : phoneType;
try {
  if (phoneType != null) {
    params.put("radioType", phoneType);
  }
} catch (Exception e) {}

/*
 * The below code doesn't work I think.

JSONArray cellList = …

是否可以使用本地存储在设备上的图像作为标记图标？我可以使用URL并且它可以工作,但是当我尝试使用本地图像时它将无法加载.我应该如何参考图像？这是一个多平台应用程序,因此我无法使用Android等设备特定路径file:///android:asset/

map.addMarker({
    'position': new plugin.google.maps.LatLng(13.7579507,100.5643353),
    'title': 'Fortune Town',
    'icon': '../templates/icon2.png'
}, function(marker) {
    marker.showInfoWindow();
});

我正在使用Ionic Framework(使用AngularJS)和Apache Cordova以及来自https://github.com/wf9a5m75/phonegap-googlemaps-plugin/的Google Maps插件

我正在寻找一种从c ++(Android NDK)为网络摄像头设置场景模式值的方法.

OpenCV在初始化时从网络摄像头获取值.在下面的日志中,日志说Supported Scene Modes: auto,action,portrait,landscape,beach,fireworks,night,night-portrait,snow,sports,steadyphoto,sunset,theatre,barcode.

我想为相机设置一个值(例如海滩).

我正在尝试使用NodObjC创建一个带有Node.js的可可应用程序.我一直在创建一个只在MacOS X上作为HTTP服务器运行的应用程序.

NodObjC https://github.com/TooTallNate/NodObjC

我想在StatusBar上显示带有图标的服务器状态,如下所示.

我试过这样的:

var $ = require('NodObjC');
$.import('Foundation');
$.import('Cocoa');

var systemStatusBar = $.NSStatusBar('systemStatusBar');
var _statusItem = systemStatusBar('statusItemWithLength', $.NSVariableStatusItemLength);
_statusItem('setHighlightMode', 'YES');
var title = $.NSString('stringWithUTF8String', 'Test');
_statusItem('setTitle', title);
_statusItem('setMenu', systemStatusBar);

但是这段代码会导致错误

有没有办法在绘制后更改PolygonOption的填充颜色并更新Google地图而不清除并重新绘制它？

我目前正在做的是

    polygonOptions.fillColor(context.getResources().getColor(R.color.polygonSolidFill));
    polygonOptions.strokeWidth(2);
    polygonOptions.strokeColor(Color.BLACK);
    // Add some LatLngs 
    googleMap.addPolygon(polygonOptions);

当用户在某个位置时,我想更改填充颜色.我正在做的是实现颜色更新

    polygonOptions.fillColor(context.getResources().getColor(R.color.polygonSolidFill2));
    googleMap.clear();
    googleMap.addPolygon(polygonOptions);

然而,当它被清除并重新绘制时,地图中会有一个小的闪烁,我想避免.
