android 定位(获取经纬度)

直接上代码:

重要的 是 获取位置权限,否则  是获取不到的!!!

 LocationManager lm = (LocationManager) getSystemService(Context.LOCATION_SERVICE);

        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
        //getBestProvider 只有允许访问调用活动的位置供应商将被返回
        String providerName = lm.getBestProvider(criteria, true);



        if (providerName != null) {
            if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
                Toast.makeText(this, "没有权限", Toast.LENGTH_SHORT).show();
                return;
            }

            Location location = lm.getLastKnownLocation(providerName);

            //获取维度信息
            double latitude = location.getLatitude();
            //获取经度信息
            double longitude = location.getLongitude();
           
            Log.i("获取经纬度", "定位方式： " + providerName + "  维度：" + latitude + "  经度：" + longitude);

        } else {
            Toast.makeText(this, "1.请检查网络连接 \n2.请打开我的位置", Toast.LENGTH_SHORT).show();
        }
