Android(安卓)获取经纬度

需求

获取手机自带的经纬度

代码

1、配置列表中加入权限

2、代码

public class LocationActivity extends Activity {    //入口是getLocation    /**     * 定位：权限判断     */    @RequiresApi(api = Build.VERSION_CODES.M)    private void getLocation() {        //检查定位权限        ArrayList permissions = new ArrayList<>();        if (ActivityCompat.checkSelfPermission(WebViewActivity.this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED) {            permissions.add(Manifest.permission.ACCESS_FINE_LOCATION);        }        if (ActivityCompat.checkSelfPermission(WebViewActivity.this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {            permissions.add(Manifest.permission.ACCESS_COARSE_LOCATION);        }        //判断        if (permissions.size() == 0) {//有权限，直接获取定位            getLocationLL();        } else {//没有权限，获取定位权限            requestPermissions(permissions.toArray(new String[permissions.size()]), 2);            LogUtil.d("*************", "没有定位权限");        }    }    /**     * 定位：获取经纬度     */    private void getLocationLL() {        LogUtil.d("*************", "获取定位权限1 - 开始");        Location location = getLastKnownLocation();        if (location != null) {            //传递经纬度给网页            String result = "{code: '0',type:'2',data: {longitude: '" + location.getLongitude() + "',latitude: '" + location.getLatitude() + "'}}";            wvShow.loadUrl("javascript:callback(" + result + ");");            //日志            String locationStr = "维度：" + location.getLatitude() + "\n"                    + "经度：" + location.getLongitude();            LogUtil.d("*************", "经纬度：" + locationStr);        } else {            Toast.makeText(this, "位置信息获取失败", Toast.LENGTH_SHORT).show();            LogUtil.d("*************", "获取定位权限7 - " + "位置获取失败");        }    }    /**     * 定位：得到位置对象     * @return     */    private Location getLastKnownLocation() {        //获取地理位置管理器        LocationManager mLocationManager = (LocationManager) getApplicationContext().getSystemService(LOCATION_SERVICE);        List providers = mLocationManager.getProviders(true);        Location bestLocation = null;        for (String provider : providers) {            Location l = mLocationManager.getLastKnownLocation(provider);            if (l == null) {                continue;            }            if (bestLocation == null || l.getAccuracy() < bestLocation.getAccuracy()) {                // Found best last known location: %s", l);                bestLocation = l;            }        }        return bestLocation;    }    /**     * 定位：权限监听     * @param requestCode     * @param permissions     * @param grantResults     */    @Override    public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {        switch (requestCode) {            case 2://定位                if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {                    LogUtil.d("*************", "同意定位权限");                    getLocationLL();                } else {                    Toast.makeText(this, "未同意获取定位权限", Toast.LENGTH_SHORT).show();                }                break;            default:        }    }}
