arcgis for android 学习 - (7) 在真机上 模拟GPS

必须先开启“允许模拟地点”
方法： 打开设备的，设置 - 应用程序 - 开发 - “允许模拟地点”

1.在 AndroidManifest.xml 里添加相应的 “允许模拟位置的权限”

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

2.创建 一个 “用于模拟的坐标提供者”

LocationManager locationManager = (LocationManager) mContext
.getSystemService(Context.LOCATION_SERVICE);
if (locationManager.getProvider(mMockProviderName) == null) {
locationManager.addTestProvider(mMockProviderName, false, true,
false, false, false, false, false, 0, 5);
locationManager.setTestProviderEnabled(mMockProviderName, true);

}

注意：mMockProviderName 是你随意定的名称，后面在使用（获得位置）时，用这个名称。

3.构建（模拟的）坐标位置

Location loc = new Location(mMockProviderName);
loc.setTime(System.currentTimeMillis());
loc.setLatitude(latitude);
loc.setLongitude(longitude);
locationManager.setTestProviderLocation(mMockProviderName, loc);

Log.i("gps", String.format("once: x=%s y=%s", longitude, latitude));

注意：我们可以多次间歇的调用此方法来 模拟 位置的变化。

4.获得（使用）坐标位置。

loc = (LocationManager) context
.getSystemService(Context.LOCATION_SERVICE);

loc.requestLocationUpdates(NAME_MOCK_GPS_PROVIDER, 1000, 10,

mListener);

这里的NAME_MOCK_GPS_PROVIDER的名称 和前面“第2步”里名称是一致的。

好了。让代码跑起来。
