java通过经纬度或取城市名_通过经纬度获取城市名/地址(不需要三方包)
1:getLocation()方法筛选出最优获取经纬度的方法
2:MapThread线程通过将getLocation()获取的经纬度上传而获取城市名
public class PositionActivity extends BaseActivity implements IInit, IResponseHandler, View.OnClickListener {
private TextView mLocationTV, mCategoryTV;//位置.种类
private double latitude, longitude;//经纬度
private String mapUriStr = "http://maps.google.cn/maps/api/geocode/json?latlng={0},{1}&sensor=true&language=zh-CN";
private HttpResponse httpResponse = null;
private HttpEntity httpEntity = null;

private Handler handler;
private String result;

}
@Override
public void init() {
mLocationTV = (TextView) findViewById(R.id.tv_goods_location);,
getLocation();//获取经纬度
mapThread = new MapThread();
mapThread.start();
}
//获取经纬度
public void getLocation() {
LocationManager lm = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
List lp = lm.getAllProviders();// 返回所有已知的位置提供者的名称列表，包括未获准访问或调用活动目前已停用的。
for (String item : lp) {
// Log.i("---->可用位置服务:", item);
}
Criteria criteria = new Criteria();
criteria.setCostAllowed(false);//设置位置服务免费
criteria.setAccuracy(Criteria.ACCURACY_COARSE); //设置水平位置精度
String providerName = lm.getBestProvider(criteria, true); //getBestProvider 只有允许访问调用活动的位置供应商将被返回
if (providerName != null) {
Location location = lm.getLastKnownLocation(providerName);
latitude = location.getLatitude();//获取维度信息
longitude = location.getLongitude();//获取经度信息
} else {
ToastUtil.show(this, "1.请检查网络连接 \n2.请打开我的位置");
}
}
