Android: 如何開啟webview的LBS功能

Android: 如何開啟webview的LBS功能 ，不做過多解釋代碼全貼在下面。

首先想要用到手機的LBS功能，必須在androidManifest.xml中請求權限.

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

1. private void loadUrl(){
2. browser.getSettings().setJavaScriptEnabled(true);
3. browser.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
4. browser.getSettings().setGeolocationEnabled(true);
5. GeoClient geo = new GeoClient();
6. browser.setWebViewClient(new PTCWebViewClient(this, browser));
7. browser.setWebChromeClient(geo);
8. String origin = "";
9. geo.onGeolocationPermissionsShowPrompt(origin, this);
10. browser.loadUrl("http://www.mytransport.sg");
11. }

PTCWebViewClient.java

1. public class PTCWebViewClient extends WebViewClient {
3. private ProgressDialog pd;
5. public PTCWebViewClient(Context con, final WebView web){
6. pd = new ProgressDialog(con);
7. pd.setProgressStyle(ProgressDialog.STYLE_SPINNER);
8. pd.setTitle("MTC LTA");
9. 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. }
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. }

1. class GeoClient extends WebChromeClient {
3. @Override
4. public void onGeolocationPermissionsShowPrompt(String origin,
5. Callback callback) {
6. super.onGeolocationPermissionsShowPrompt(origin, callback);
7. callback.invoke(origin, true, false);
8. }
9. }
