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 plain copy print ?

<uses-permissionandroid:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permissionandroid: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 plain copy print ?

privatevoidloadUrl(){
browser.getSettings().setJavaScriptEnabled(true);
browser.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
browser.getSettings().setGeolocationEnabled(true);
GeoClientgeo=newGeoClient();
browser.setWebViewClient(newPTCWebViewClient(this,browser));
browser.setWebChromeClient(geo);
Stringorigin="";
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");    }
