Andorid App 没有自动识别位置

Question

I have converted a Website's page( https://taxif.com/online.html ) to an Android App by using WebView. The website automatically fetches the current location but the app is not fetching the current location .

Please let me know how can I auto fetch the current location in webview same as in the webpage.

public class MainActivity extends AppCompatActivity {
    private SwipeRefreshLayout refreshLayout;
    private WebView webView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        webView = findViewById(R.id.myWebView);
        refreshLayout = findViewById(R.id.refresh);

        refreshLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
            @Override
            public void onRefresh() {
                webView.reload();
            }
        });

        webView.getSettings().setLoadWithOverviewMode(true);
        webView.getSettings().setUseWideViewPort(true);


        webView.setWebChromeClient(new MyChromeClient());
        webView.setWebViewClient(new BrowserClient(refreshLayout));

        WebSettings webSettings = webView.getSettings();
        webSettings.setJavaScriptEnabled(true);

        if(networkInfo != null && networkInfo.isConnectedOrConnecting()){
            webView.loadUrl("https://taxif.com/online.html");
        }else{
            Toast.makeText(this,"You don't have any active internet connection",Toast.LENGTH_SHORT).show();

Answer 1

in android, you need to write the code to get the user location, this can be done on the "onPageStarted()" method, just check the url for the page that usses the location and if true, ask the user permission and get the device location. something like below:

@Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
    super.onPageStarted(view, url, favicon);
    if(url.equals(locationRequiredUrl) {
    getUserPermission();
    getUserLocation();
    }
    refreshLayout.setRefreshing(true);
}
