Question

当我使用GpsProvider时，我得到了当前的位置。但是，只有当我使用wifi获得wifi网络时才需要获取当前位置。我使用NetworProvider来实现它，但我不能我使用的代码如下

    public static void requestSingleUpdate(final Context context,
        final LocationCallback callback) {

    final LocationManager locationManager = (LocationManager) context
            .getSystemService(Context.LOCATION_SERVICE);

    boolean isNetworkEnabled = locationManager
            .isProviderEnabled(LocationManager.NETWORK_PROVIDER);
    if (isNetworkEnabled) {
        Criteria criteria = new Criteria();
        criteria.setAccuracy(Criteria.ACCURACY_COARSE);

        locationManager.requestSingleUpdate(criteria,
                new LocationListener() {
                    @Override
                    public void onLocationChanged(Location location) {
                        callback.onNewLocationAvailable(location);
                    }

                    @Override
                    public void onStatusChanged(String provider,
                            int status, Bundle extras) {
                    }

                    @Override
                    public void onProviderEnabled(String provider) {
                    }

                    @Override
                    public void onProviderDisabled(String provider) {
                    }
                }, null);}

我的许可如下。

 <uses-permission android:name="android.permission.WAKE_LOCK" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.VIBRATE"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
 <!-- Network State Permissions -->
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />\
<uses-permission android:name="android.permission.CHANGE_NETWORK_STATE"/>
<uses-permission android:name="android.permission.WRITE_SETTINGS"/>
<uses-permission     android:name="android.permission.ACCESS_COARSE_LOCATION"/>

谢谢：）

<强> ConnectivityManager

回答有关网络连接状态的查询的类。它还会在网络连接发生变化时通知应用程序得到一个通过调用此类的实例 Context.getSystemService（Context.CONNECTIVITY_SERVICE）。

<强> TYPE_WIFI

WIFI数据连接。活动时，所有数据流量都将使用此功能默认情况下网络类型的界面（它有默认路由）。

您可以在逻辑

下使用

<form novalidate role="form" name="filterForm" class="form-inline">
  <div ng-repeat="criteria in criterias">
    <div class="m-b">
       <div class="form-group s-b">
         <span>Country</span>
           <select class="form-control" ng-options="item for item in country" name="country" ng-model="classification.country">
           </select>
         </div>
         <div class="form-group s-b">
           <span>State</span>
             <select ng-options="item for item in state" class="form-control" name="state" ng-model="criteria.state"  style="max-width:50%">
             </select>
          </div>
          <div class="form-group s-b">
            <span>City</span>
              <select class="form-control"  ng-options="item for item in Cities"  name="account" ng-model="criteria.city" style="max-width:50%;">
              </select>
          </div>
          <div class="form-group s-b">
            <span>Predicate</span>
            <select class="form-control" name="account" ng-model="criteria.predicate">
               <option value="matches">Matches</option>
               <option value="not-matches">Not Matches</option>
             </select>
           </div>
           <div class="form-group s-b">
             <span>Value</span>
             <select class="form-control" name="account" ng-model="criteria.value"  style="min-width:100px;">
             </select>
           </div>
           <div class="form-group">
             <span>
               <button class="btn btn-sm btn-primary pad-btn" type="submit" ng-click="addCriteria()"><i class="fa fa-plus"></i>
               </button>
               <button class="btn btn-sm btn-danger pad-btn" type="submit" ng-click="deleteCriteria(criteria)"><i
                        class="fa fa-minus"></i></button>
             </span>
           </div>
         </div>
       </div>
       <button class="btn btn-sm btn-primary pad-btn align-center" type="submit" ng-click="searchParams(filterForm)">Submit
                <i class="fa fa-check"></i></button>
       <button class="btn btn-sm btn-warning pad-btn align-center" type="submit" ng-click="resetFilter()">Reset
                <i class="fa fa-reply"></i></button>
     </form>

在清单文件中添加此内容。

ConnectivityManager connManagerObj = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo WifiObj = connManagerObj.getNetworkInfo(ConnectivityManager.TYPE_WIFI);

if (WifiObj.isConnected()) {
    //Add your Code
}

在android中只使用wifi获取当前位置
