java - Fragment webView无法检测到Google map (您的位置)

Question

使用 webView 浏览时，Google map 无法检测到“您的位置”。如何在 webView 环境中支持和启用 GeoLocation，它可以检测您的位置。也许我需要在 Java 上添加额外的代码？我在 fragment 中使用 webView。至此，google map 本身就可以成功加载了。

HomeFragment.java

public class HomeFragment extends Fragment {

    public HomeFragment() {

    }

    WebView webView;
    String url = "https://google.com";

    @Override
    public View onCreateView(@NonNull LayoutInflater inflater,
                             ViewGroup container, Bundle savedInstanceState)
    {

        View v = inflater.inflate(R.layout.fragment_home, container, false);
        webView = (WebView)v.findViewById(R.id.webView);
        webView.loadUrl(url);
        WebSettings settings = webView.getSettings();
        settings.setJavaScriptEnabled(true);
        settings.setGeolocationEnabled(true);
        settings.setAppCacheEnabled(true);
        settings.setDatabaseEnabled(true);
        settings.setDomStorageEnabled(true);
        webView.setWebViewClient(new MyWebViewClient());
        return v;
    }


    private class MyWebViewClient extends WebViewClient{
        @Override
        public void onPageStarted(WebView view, String url, Bitmap favicon) {
            // TODO Auto-generated method stub
            super.onPageStarted(view, url, favicon);
        }

        @SuppressWarnings("deprecation")
        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            if (url.startsWith("mailto:")) {
                //Handle mail Urls
                startActivity(new Intent(Intent.ACTION_SENDTO, Uri.parse(url)));
            } else if (url.startsWith("tel:")) {
                //Handle telephony Urls
                startActivity(new Intent(Intent.ACTION_DIAL, Uri.parse(url)));
            } else {
                view.loadUrl(url);
            }
            return true;
        }

        @TargetApi(Build.VERSION_CODES.N)
        @Override
        public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) {
            final Uri uri = request.getUrl();
            if (uri.toString().startsWith("mailto:")) {
                //Handle mail Urls
                startActivity(new Intent(Intent.ACTION_SENDTO, uri));
            } else if (uri.toString().startsWith("tel:")) {
                //Handle telephony Urls
                startActivity(new Intent(Intent.ACTION_DIAL, uri));
            } else {
                //Handle Web Urls
                view.loadUrl(uri.toString());
            }
            return true;
        }
    }
}

权限使用

<uses-permission android:name="android.permission.INTERNET"></uses-permission>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"></uses-permission>
<uses-permission android:name="android.permission.CALL_PHONE" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_BACKGROUND_LOCATION" />

那么，您检查过权限运行时吗？因为，一些权限会在运行时检查(如位置、相机等)。
