做一款自己的安卓天气闹钟（5）——使用百度地图SDK获取定位

配置SDK

1. 申请网址http://lbsyun.baidu.com/apiconsole/key/create
2. 获取SHA1http://lbsyun.baidu.com/index.php?title=androidsdk/guide/key
3. 按照操作创建完了之后拿到了访问应用（AK）
4. 下载SDKhttp://lbsyun.baidu.com/index.php?title=sdk/download&action#selected=location_all，只需要基础定位
5. 配置SDK http://lbsyun.baidu.com/index.php?title=android-locsdk/guide/create-project/android-studio

编写代码

1. show类实现接口BDLocationListener
   public class Show extends Fragment implements CompoundButton.OnCheckedChangeListener, BDLocationListener {
2. 定义相关变量

private TextView _locationTextView;
private LocationClient _locationClient;
private static final int BAIDU_READ_PHONE_STATE =100;

3. 配置client并申请权限

_locationClient=new LocationClient(getContext());
_locationClient.registerLocationListener(this);
LocationClientOption option=new LocationClientOption();
option.setIsNeedAddress(true);
option.setLocationMode(LocationClientOption.LocationMode.Hight_Accuracy);//设置高精度定位定位模式
option.setOpenGps(true); // 打开gps
option.setCoorType("bd09ll"); // 设置坐标类型
option.setScanSpan(1000);
_locationClient.setLocOption(option);

if(ActivityCompat.checkSelfPermission(getActivity(),Manifest.permission.READ_PHONE_STATE)!= PackageManager.PERMISSION_GRANTED) {
    // 申请一个（或多个）权限，并提供用于回调返回的获取码（用户定义）
    requestPermissions( new String[]{ Manifest.permission.READ_PHONE_STATE },BAIDU_READ_PHONE_STATE );
}else{
    _locationClient.start();
}

4. 重写权限结果函数

@Override
public void onRequestPermissionsResult(int requestCode,String[] permissions, int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    switch (requestCode) {
        //requestCode即所声明的权限获取码，在checkSelfPermission时传入
        case 1:
            BAIDU_READ_PHONE_STATE:
            if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                _locationClient.start();
            } else {
                Log.i("tag", "onRequestPermissionsResult: " + "没有获取到权限");
            }
            break;
        default:
            break;
    }
}

5. 重写定位结果函数

@Override
public void onReceiveLocation(BDLocation bdLocation) {
    String addr = bdLocation.getAddrStr();    //获取详细地址信息
    String country = bdLocation.getCountry();    //获取国家
    String province = bdLocation.getProvince();    //获取省份
    String city = bdLocation.getCity();    //获取城市
    String district = bdLocation.getDistrict();    //获取区县
    String street = bdLocation.getStreet();    //获取街道信息
    _locationTextView.setText(city+district);
    _locationClient.stop(); //获得结果之后停止，否则会一直定位
}
