Android 23使用定位权限报错Call requires permission which may be rejected by user

报错了“Call requires permission which may be rejected by user: code should explicitly check to see if permission is available (with checkPermission) or explicitly handle a potential SecurityException”
权限问题
使用时，需要检查用户是否授权

代码解决（亲测可用）：

private void getlocationGps(){//此处的判定是主要问题，API23之后需要先判断之后才能调用locationManager中的方法//包括这里的getLastKnewnLocation方法和requestLocationUpdates方法    if(ContextCompat.checkSelfPermission(this,android.Manifest.permission.ACCESS_FINE_LOCATION)== PackageManager.PERMISSION_GRANTED) {        //获取定位服务        locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);        //获取当前可用的位置控制器        List<String> list = locationManager.getProviders(true);        if (list.contains(LocationManager.GPS_PROVIDER)) {            //是否为GPS位置控制器            provider = LocationManager.GPS_PROVIDER;        } else if (list.contains(LocationManager.NETWORK_PROVIDER)) {            //是否为网络位置控制器            provider = LocationManager.NETWORK_PROVIDER;        } else {            Toast.makeText(this, "请检查网络或GPS是否打开",                    Toast.LENGTH_LONG).show();            return;        }        Location location = locationManager.getLastKnownLocation(provider);        if (location != null) {            //获取当前位置，这里只用到了经纬度            String string = "纬度为：" + location.getLatitude() + ",经度为："                    + location.getLongitude();        }//绑定定位事件，监听位置是否改变//第一个参数为控制器类型第二个参数为监听位置变化的时间间隔（单位：毫秒）//第三个参数为位置变化的间隔（单位：米）第四个参数为位置监听器        locationManager.requestLocationUpdates(provider, 2000, 2, locationListener);    }}public LocationListener locationListener=new LocationListener() {    @Override    public void onLocationChanged(Location location) {    }    @Override    public void onStatusChanged(String provider, int status, Bundle extras) {    }    @Override    public void onProviderEnabled(String provider) {    }    @Override    public void onProviderDisabled(String provider) {    }};    //关闭时解除监听器    @Override    protected void onDestroy() {        // TODO Auto-generated method stub        super.onDestroy();        //api23需要这样写        if(ContextCompat.checkSelfPermission(this,android.Manifest.permission.ACCESS_FINE_LOCATION)== PackageManager.PERMISSION_GRANTED) {            if (locationManager != null) {                locationManager.removeUpdates(locationListener);            }        }    }
