Android原生Gps获取定位

去年公司写东西用到了这个，然后遗忘了，今年又来一波这个功能整理一下吧。

老样子，拷贝可用！！！

首先是工具类：

GPS定位

public class GPSLocation implements LocationListener {
    private GPSLocationListener mGpsLocationListener;


    public GPSLocation(GPSLocationListener gpsLocationListener) {
        this.mGpsLocationListener = gpsLocationListener;
    }

    @Override
    public void onLocationChanged(Location location) {
        if (location != null) {
            mGpsLocationListener.UpdateLocation(location);
        }
    }


    @Override
    public void onStatusChanged(String provider, int status, Bundle extras) {
        mGpsLocationListener.UpdateStatus(provider, status, extras);
        switch (status) {
            case LocationProvider.AVAILABLE:
                mGpsLocationListener.UpdateGPSProviderStatus(GPSProviderStatus.GPS_AVAILABLE);
                break;
            case LocationProvider.OUT_OF_SERVICE:
                mGpsLocationListener.UpdateGPSProviderStatus(GPSProviderStatus.GPS_OUT_OF_SERVICE);
                break;
            case LocationProvider.TEMPORARILY_UNAVAILABLE:
                mGpsLocationListener.UpdateGPSProviderStatus(GPSProviderStatus.GPS_TEMPORARILY_UNAVAILABLE);
                break;
        }
    }

    @Override
    public void onProviderEnabled(String provider) {
        mGpsLocationListener.UpdateGPSProviderStatus(GPSProviderStatus.GPS_ENABLED);
    }

    @Override
    public void onProviderDisabled(String provider) {
        mGpsLocationListener.UpdateGPSProviderStatus(GPSProviderStatus.GPS_DISABLED);
    }
}

GPS管理者类

        }
        //定位类型：GPS

        isOPenGps = false;
        //默认定位时间间隔为30分钟,此处与下面都为30分钟
        mMinTime = 30*60*1000;
        //mMinTime = 10000;
        //默认位置可更新的最短距离为0m
        mMinDistance = 0;
    }

    public static GPSLocationManager getInstances(Activity context) {

            synchronized (objLock) {
                if (gpsLocationManager == null) {
                    gpsLocationManager = new GPSLocationManager(context);
                }
            }

GPS定位信息

public class GPSProviderStatus {

    //用户手动开启GPS
    public static final int GPS_ENABLED = 0;
    //用户手动关闭GPS
    public static final int GPS_DISABLED = 1;
    //服务已停止，并且在短时间内不会改变

    //服务暂时停止，并且在短时间内会恢复
    public static final int GPS_TEMPORARILY_UNAVAILABLE = 3;
    //服务正常有效
    public static final int GPS_AVAILABLE = 4;
}

GPS定位事件

public interface GPSLocationListener {
    /**
     * 方法描述：位置信息发生改变时被调用
     *
     * @param location 更新位置后的新的Location对象
     */
    void UpdateLocation(Location location);

    /**
     * 方法描述：provider定位源类型变化时被调用
     *
     * @param provider provider的类型
     * @param status   provider状态
     * @param extras   provider的一些设置参数（如高精度、低功耗等）
     */
    void UpdateStatus(String provider, int status, Bundle extras);

    /**
     * 方法描述：GPS状态发生改变时被调用（GPS手动启动、手动关闭、GPS不在服务区、GPS占时不可用、GPS可用)
     *
     * @param gpsStatus 详见{@link GPSProviderStatus}
     */
    void UpdateGPSProviderStatus(int gpsStatus);

}

 

使用方法，在点击事件里调用：

TextView textView = (TextView) findViewById(R.id.getLaocation);
textView.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        

GPSLocationManager gpsManager = GPSLocationManager.getInstances(MainActivity.this);
        gpsManager.setHandler(handler);
        //开启定位
        GPS_FIRST_FIX = true;
        gpsManager.start(new MyListener(), true);
    }
});

自定义MyListen

class MyListener implements GPSLocationListener {

    @Override
    public void UpdateLocation(Location location) {
        if (location != null) {
            log = location.getLongitude();
            lat = location.getLatitude();
            if (GPS_FIRST_FIX = true) {
                gpsManager.start_TimerTask();
                GPS_FIRST_FIX = false;
            }
            Log.e("gps==", "经度：" + location.getLongitude() + "\n纬度：" + location.getLatitude());
        }
    }

    @Override
    public void UpdateStatus(String provider, int status, Bundle extras) {
        if ("gps" == provider) {
            Log.e("UpdateStatus--gps", "定位类型：" + provider);
        }
    }

    @Override
    public void UpdateGPSProviderStatus(int gpsStatus) {
        switch (gpsStatus) {

            case GPSProviderStatus.GPS_ENABLED:
                //   Toast.makeText(MainActivity.this, "GPS开启", Toast.LENGTH_SHORT).show();
                break;
            case GPSProviderStatus.GPS_DISABLED:
                //    Toast.makeText(MainActivity.this, "GPS关闭", Toast.LENGTH_SHORT).show();
                break;
            case GPSProviderStatus.GPS_OUT_OF_SERVICE:
                //  Toast.makeText(MainActivity.this, "GPS不可用", Toast.LENGTH_SHORT).show();
                break;
            case GPSProviderStatus.GPS_TEMPORARILY_UNAVAILABLE:
                //  Toast.makeText(MainActivity.this, "当前GPS状态为暂停服务状态", Toast.LENGTH_SHORT).show();
                break;
            case GPSProviderStatus.GPS_AVAILABLE:
                //     Toast.makeText(MainActivity.this, "GPS可用啦", Toast.LENGTH_SHORT).show();
                break;
        }
    }
}

在Handler获取详细地区信息:

Handler handler = new Handler() {
    @Override
    public void handleMessage(Message msg) {
        // TODO Auto-generated method stub
        // 要做的事情
        super.handleMessage(msg);
        Geocoder gc = new Geocoder(MainActivity.this, Locale.getDefault());
        List<Address> locationList = null;
        try {
            locationList = gc.getFromLocation(lat, log, 1);
        } catch (IOException e) {
            e.printStackTrace();
        }
        if (locationList.size() > 0) {
            Address address = locationList.get(0);//得到Address实例
            String locality = address.getLocality();//得到城市名称，比如：北京市
            String addressLine = address.getAddressLine(0);//得到周边信息，包括街道等，i=0，得到街道名称
            Log.e("motejia", "handleMessage: =============="+locality+"========="+addressLine);
        }
        //在Handler每次运行时候获取数据
    }
};

获取地址定位会有微小偏差，原生定位导致。
