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.

 

view sourceprint?

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

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

 

webview加载URL以及相关设置

view sourceprint?

01.private void loadUrl(){ 

02.browser.getSettings().setJavaScriptEnabled(true); 

03.browser.getSettings().setJavaScriptCanOpenWindowsAutomatically(true); 

04.browser.getSettings().setGeolocationEnabled(true); 

05.GeoClient geo = new GeoClient(); 

06.browser.setWebViewClient(new PTCWebViewClient(this, browser)); 

07.browser.setWebChromeClient(geo); 

08.String origin = ""; 

09.geo.onGeolocationPermissionsShowPrompt(origin, this); 

10.browser.loadUrl("http://www."); 

11.} 

PTCWebViewClient.java

view sourceprint?

01.public class PTCWebViewClient extends WebViewClient { 

02. 

03.private ProgressDialog pd; 

04. 

05.public PTCWebViewClient(Context con, final WebView web){ 

06.pd = new ProgressDialog(con); 

07.pd.setProgressStyle(ProgressDialog.STYLE_SPINNER); 

08.pd.setTitle("MTC LTA"); 

09.pd.setMessage("Loading, please wait..."); 

10.pd.setIcon(R.drawable.icon); 

11.pd.setButton("Cancel", new ProgressDialog.OnClickListener(){ 

12.@Override 

13.public void onClick(DialogInterface dialog, int which) { 

14.web.stopLoading(); 

15.} 

16.}); 

17.pd.setIndeterminate(false); 

18.pd.setCancelable(true); 

19.} 

20. 

21.@Override 

22.public boolean shouldOverrideUrlLoading(WebView view, String url) { 

23.view.loadUrl(url); 

24.return true; 

25.} 

26.@Override 

27.public void onPageStarted(WebView view, String url, Bitmap favicon) { 

28.super.onPageStarted(view, url, favicon); 

29.pd.show(); 

30.} 

31.@Override 

32.public void onPageFinished(WebView view, String url) { 

33.super.onPageFinished(view, url); 

34.pd.dismiss(); 

35.} 

36.} 

GeoClient.java

view sourceprint?

01.class GeoClient extends WebChromeClient { 

02. 

03.@Override 

04.public void onGeolocationPermissionsShowPrompt(String origin, 

05.Callback callback) { 

06.super.onGeolocationPermissionsShowPrompt(origin, callback); 

07.callback.invoke(origin, true, false); 

08.}
