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. 网站自动获取当前位置，但应用程序未获取当前位置。

请让我知道如何自动获取 webview 中的当前位置，与网页中相同。

MainActivity.java文件

import androidx.appcompat.app.AppCompatActivity;
import androidx.swiperefreshlayout.widget.SwipeRefreshLayout;

import android.content.Context;
import android.net.ConnectivityManager;
import android.net.NetworkInfo;
import android.os.Bundle;
import android.view.View;
import android.webkit.WebSettings;
import android.webkit.WebView;
import android.widget.Toast;


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);
        webSettings.setAllowFileAccess(true);
        webSettings.setAppCacheEnabled(true);

        webSettings.setRenderPriority(WebSettings.RenderPriority.HIGH);
        webSettings.setCacheMode(WebSettings.LOAD_CACHE_ELSE_NETWORK);
        webSettings.setAppCacheEnabled(true);
        webView.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY);
        webSettings.setLayoutAlgorithm(WebSettings.LayoutAlgorithm.NARROW_COLUMNS);
        webSettings.setSavePassword(true);
        webSettings.setSaveFormData(true);
        webSettings.setEnableSmoothTransition(true);

        loadWebPage();

    }

    private void loadWebPage() {

        ConnectivityManager connectivityManager = (ConnectivityManager) MainActivity.this
                .getApplication().getSystemService(Context.CONNECTIVITY_SERVICE);
        NetworkInfo networkInfo = connectivityManager.getActiveNetworkInfo();

        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();
        }
    }
}

BrowserClient.java文件

import android.graphics.Bitmap;
import android.webkit.WebResourceError;
import android.webkit.WebResourceRequest;
import android.webkit.WebView;
import android.webkit.WebViewClient;

import androidx.swiperefreshlayout.widget.SwipeRefreshLayout;

public class BrowserClient extends WebViewClient {

    SwipeRefreshLayout refreshLayout;

    public BrowserClient(){

    }

    public BrowserClient(SwipeRefreshLayout refreshLayout) {
        this.refreshLayout = refreshLayout;
    }

    @Override
    public void onReceivedError(WebView view, WebResourceRequest request, WebResourceError error) {
        super.onReceivedError(view, request, error);
    }

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

    @Override
    public void onPageFinished(WebView view, String url) {
        super.onPageFinished(view, url);
        refreshLayout.setRefreshing(false);
    }
}

AndroidManifest.xml文件

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.booking">

    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>

        android:theme="@style/Theme.BookingApp">

        <!--

               app to run.

        <meta-data
            android:name="com.google.android.wearable.standalone"
            android:value="true" />

        <activity
            android:name=".SplashScreen"
            android:label="Booking App"><intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter></activity>
        <activity android:name=".MainActivity">

        </activity>
    </application>

</manifest>

在 android 中，您需要编写代码来获取用户位置，这可以在“onPageStarted()”方法中完成，只需检查 url 以获取使用该位置的页面，如果为真，请询问用户权限并获取设备位置。 如下所示：

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