android - 此代码完美适用于 GPS，但我想使用 Wifi。该怎么做？

Question

此代码与网络完美配合，但我需要进行 WiFi 测试 GPSwifi。所以我想同时检查 GPS wifi 和网络。对如何在 Android 应用程序中完成这项工作没有任何帮助。

    public class Map extends MapActivity {
        double longitude;
        double latitude;

        }



        public class MyLocationListener implements LocationListener {

            public void onLocationChanged(Location loc) {

                mapView.getOverlays().clear();

    }

此代码适用于 android 网络基础，但我需要使用 GPS wifi ..

        }

        public CustomItemizedOverlay(Drawable defaultMarker, Context context) {
            super(boundCenterBottom(defaultMarker));
            mcontext = context;
        }

        @Override
        protected OverlayItem createItem(int i) {
            // TODO Auto-generated method stub
            return mapOverlays.get(i);
        }

            OverlayItem item = mapOverlays.get(index);
            AlertDialog.Builder dialog = new AlertDialog.Builder(mcontext);
            dialog.setTitle(item.getTitle());
            dialog.setMessage(item.getSnippet());
            dialog.show();
            return true;
        }

        public void addOverlay(OverlayItem overlay) {
            mapOverlays.add(overlay);
            populate();
        }

    }

你可以做一件事..在 Activity 启动时自动启动你的 WiFi

 protected void onStart() {
         // TODO Auto-generated method stub
         super.onStart();

           WifiManager wifiManager = (WifiManager) getSystemService(Context.WIFI_SERVICE);
             if (wifiManager != null) {

             wifiManager.setWifiEnabled(true);
             }
        } 

将权限也放在 list 文件中:

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"  />
    <uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />

    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
