android: 如何开启webview的LBS功能

不做过多解释代码全贴在下面。

首先想要用到手机的LBS功能，必须在androidManifest.xml中请求权限.

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

webview加载URL以及相关设置

private void loadUrl(){    browser.getSettings().setJavaScriptEnabled(true);    browser.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);    browser.getSettings().setGeolocationEnabled(true);    GeoClient geo = new GeoClient();    browser.setWebViewClient(new PTCWebViewClient(this, browser));    browser.setWebChromeClient(geo);    String origin = "";    geo.onGeolocationPermissionsShowPrompt(origin, this);browser.loadUrl("http://www.mytransport.sg");    }

PTCWebViewClient.java

public class PTCWebViewClient extends WebViewClient {private ProgressDialog pd;public PTCWebViewClient(Context con, final WebView web){pd = new ProgressDialog(con);pd.setProgressStyle(ProgressDialog.STYLE_SPINNER);pd.setTitle("MTC LTA");pd.setMessage("Loading, please wait...");pd.setIcon(R.drawable.icon);pd.setButton("Cancel", new ProgressDialog.OnClickListener(){@Overridepublic void onClick(DialogInterface dialog, int which) {web.stopLoading();}});pd.setIndeterminate(false);pd.setCancelable(true);}@Overridepublic boolean shouldOverrideUrlLoading(WebView view, String url) {view.loadUrl(url);return true;}@Overridepublic void onPageStarted(WebView view, String url, Bitmap favicon) {super.onPageStarted(view, url, favicon);pd.show();}@Overridepublic void onPageFinished(WebView view, String url) {super.onPageFinished(view, url);pd.dismiss();}}

GeoClient.java

class GeoClient extends WebChromeClient {    @Override    public void onGeolocationPermissionsShowPrompt(String origin,    Callback callback) {    super.onGeolocationPermissionsShowPrompt(origin, callback);    callback.invoke(origin, true, false);    }    }
