android LBS模式,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.

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(){

@Override

public void onClick(DialogInterface dialog, int which) {

web.stopLoading();

}

});

pd.setIndeterminate(false);

pd.setCancelable(true);

}

@Override

public boolean shouldOverrideUrlLoading(WebView view, String url) {

view.loadUrl(url);

return true;

}

@Override

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

super.onPageStarted(view, url, favicon);

pd.show();

}

@Override

public 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);

}

}
