检查是否存在Google Streetview位置以隐藏视图 [英] Check if google streetview location exists or not to hide a view

问题描述

我目前正在开发一个Android应用程序，该程序要求我在我的应用程序中使用街景.我做了一个StreetViewActivity来显示街景.但是在该活动之前，我还有另一个名为位置活动"的活动，该活动具有将用户带到StreetViewActivity的按钮.现在，我的问题是如何检查提供的纬度和经度是否没有街景视图，然后它应该隐藏该按钮，以防止用户进入StreetViewActivity?我可以检查我的StreetViewActivity中是否存在纬度，但是我需要签入上一个活动.

I am currently working on an android application which requires me to use street view in my app. I have made a StreetViewActivity to show the street view. But before that activity, I have another activity called Location Activity that has a button that takes the user to the StreetViewActivity. Now my question is how can I check if the latitude and longitude that is provided don't have a streetview then it should hide the button that would prevent the user from going to the StreetViewActivity? I can check if the lat lng exists in my StreetViewActivity but I need to check in the previous activity.

到目前为止，我在我的StreetViewActivity中所做的事情:

What I have done so far in My StreetViewActivity:

LOCATION = new LatLng(Latitude, Longitude);
    SupportStreetViewPanoramaFragment streetViewPanoramaFragment =
            (SupportStreetViewPanoramaFragment)
                    getSupportFragmentManager().findFragmentById(R.id.streetviewpanorama);
    streetViewPanoramaFragment.getStreetViewPanoramaAsync(
            new OnStreetViewPanoramaReadyCallback() {
                @Override
                public void onStreetViewPanoramaReady(final StreetViewPanorama panorama) {

                    if (savedInstanceState == null) {

                        panorama.setPosition(LOCATION);
                        panorama.setOnStreetViewPanoramaChangeListener(new StreetViewPanorama.OnStreetViewPanoramaChangeListener() {
                            @Override
                            public void onStreetViewPanoramaChange(StreetViewPanoramaLocation loc) {
                                if (loc != null && loc.links != null) {
                                    //panorama.setPosition(LOCATION);
                                }else{
                                    Toast.makeText(PropertyStreetViewActivity.this, "No Street View Available For This Location", Toast.LENGTH_LONG)
                                            .show();
                                    finish();
                                }
                            }
                        });

                    }
                }
            });

以及我的LocationActivity的屏幕截图:

推荐答案

默认情况下，在地图上启用了街景，并且街景衣夹人"控件将显示在导航(缩放和平移)控件中.您可以通过将streetViewControl设置为false来在地图的MapOptions中隐藏此控件.

By default, Street View is enabled on a map and a Street View Pegman control appears integrated within the navigation (zoom and pan) controls. You may hide this control within the map's MapOptions by setting streetViewControl to false.

streetViewControl: false
