Question

在我的应用程序中，我正在使用Google地图，这就是为什么我要检查权限，如下所示：

if (!Constant.checkPermission(getActivity(), Manifest.permission.ACCESS_FINE_LOCATION)) {
            Constant.requestPermission(getActivity(), Manifest.permission.ACCESS_FINE_LOCATION, 101);
        } else {
            if (Constant.isOnline(getActivity())) {
                mGoogleApiClient = new GoogleApiClient.Builder(getActivity())
                        .addApi(LocationServices.API).addConnectionCallbacks(this)
                        .addOnConnectionFailedListener(this).build();
                mGoogleApiClient.connect();
                locationUpdate();
            } else {
                Constant.displayToast(getActivity(), getResources().getString(R.string.msg_internet));
            }
        }

我处理的结果如下：

public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
    switch (requestCode) {
        case FINE_LOCATION:
            Constant.displayToast(getActivity(),"FINE_LOCATION");
            Constant.displayLogE(">>>>","##"+"FINE_LOCATION");
            if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                if (!Constant.checkPermission(MapFragment.this, ACCESS_COARSE_LOCATION)) {
                    Constant.requestPermission(MapFragment.this, ACCESS_COARSE_LOCATION, CORSE_LOCATION);
                    Constant.displayToast(getActivity(),"FINE_LOCATION calling inside");
                }
                Constant.displayLogE(">>>>","##"+"calling...");
                Constant.displayToast(getActivity(),"FINE_LOCATION calling");
               // locationUpdate();
            }
            break;
        case CORSE_LOCATION:
            Constant.displayLogE(">>>>","##"+"CORSE_LOCATION");
            Constant.displayToast(getActivity(),"calling here...");
            if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                Constant.displayLogE(">>>>","##"+"calling here...");
                Constant.displayToast(getActivity(),"calling here...");
            }
            break;
        case 101:
            Constant.displayLogE(">>>>","##"+"CORSE_LOCATION");
            break;
    }
}

但是，我找不到案例101的日志：那是＆＃34;＆＃34; ##＆＃34; +＆＃34; CORSE_LOCATION＆＃34;＆＃34;。被困在这里......

可能是什么问题？感谢。

由于您调用一个从回调中返回结果的函数，您应该在您的activity类而不是片段中编写回调函数，因为您的函数是由activity而不是fragment调用的。因此，只需将回调函数粘贴到您的活动代码中即可。请记住，如果您覆盖此功能，请务必将其称为超级功能。

RequestPermissionResult（）方法没有调用
