android天气预报实现定位与天气报道

【实例简介】

此项目实现了定位功能，可以查询今天及未来四天的天气情况，采用了一个二级联动的城市选择器

【实例截图】

【核心代码】

mLocationClient = new LocationClient(getApplicationContext()); // 声明LocationClient类
mLocationClient.registerLocationListener(myListener); // 注册监听函数
initLocation();
// 开始定位
mLocationClient.start();



}

/*@Override
protected void onResume() {
// TODO Auto-generated method stub
super.onResume();
Intent intent = getIntent();
if(!"".equals(intent.getStringExtra("cityname"))){
requestJuHeData(intent.getStringExtra("cityname"));
}
}*/

private void initLocation() {
LocationClientOption option = new LocationClientOption();
option.setLocationMode(LocationMode.Hight_Accuracy);// 可选，默认高精度，设置定位模式，高精度，低功耗，仅设备
option.setCoorType("bd09ll");// 可选，默认gcj02，设置返回的定位结果坐标系
option.setScanSpan(0);// 可选，默认0，即仅定位一次，设置发起定位请求的间隔需要大于等于1000ms才是有效的
option.setIsNeedAddress(true);// 可选，设置是否需要地址信息，默认不需要
option.setOpenGps(true);// 可选，默认false,设置是否使用gps
option.setLocationNotify(true);// 可选，默认false，设置是否当gps有效时按照1S1次频率输出GPS结果
option.setIsNeedLocationDescribe(true);// 可选，默认false，设置是否需要位置语义化结果，可以在BDLocation.getLocationDescribe里得到，结果类似于“在北京天安门附近”
option.setIsNeedLocationPoiList(true);// 可选，默认false，设置是否需要POI结果，可以在BDLocation.getPoiList里得到
option.setIgnoreKillProcess(false);// 可选，默认true，定位SDK内部是一个SERVICE，并放到了独立进程，设置是否在stop的时候杀死这个进程，默认不杀死
option.SetIgnoreCacheException(false);// 可选，默认false，设置是否收集CRASH信息，默认收集
option.setEnableSimulateGps(false);// 可选，默认false，设置是否需要过滤gps仿真结果，默认需要
mLocationClient.setLocOption(option);
