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.

[html]
view plaincopyprint?

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

<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

[html]
view plaincopyprint?

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"); }

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

GeoClient.java

[java]

class GeoClient extends WebChromeClient {

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