我想将地理位置加载到 android 2.1 上的 webview 中。地理定位在我的浏览器上运行良好，但在 webview 上却失败了。
public class WebPageLoader extends Activity implements GeolocationPermissions.Callback{
WebView webview;
String geoWebsiteURL = "http://hngu.naf.cs.hut.fi/current_location.html";
public WebPageLoader() {
}
/**
* Called with the activity is first created.
*/
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
webview = (WebView) findViewById(R.id.webview);
webview.getSettings().setJavaScriptEnabled(true);
webview.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
webview.getSettings().setGeolocationEnabled(true); //seems like if i set this, the webview should prompt when I call navigator.geolocation.getCurrentPosition
GeoClient geo = new GeoClient();
webview.setWebChromeClient(geo);
String origin = ""; //how to get origin in correct format?
geo.onGeolocationPermissionsShowPrompt(origin, this); //obviously not how this is meant to be used but expected usage not documented
webview.loadUrl(geoWebsiteURL);
}
public void invoke(String origin, boolean allow, boolean remember) {
}
final class GeoClient extends WebChromeClient {
@Override
public void onGeolocationPermissionsShowPrompt(String origin,
Callback callback) {
// TODO Auto-generated method stub
super.onGeolocationPermissionsShowPrompt(origin, callback);
callback.invoke(origin, true, false);
}
}
}
我的清单.xml

当我运行该应用程序时。它显示带有标记的谷歌地图。但是，即使我的 html 文件运行良好，它也无法找到当前位置。请帮我。太感谢了。
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
webview = (WebView) findViewById(R.id.webview);
webview.getSettings().setJavaScriptEnabled(true);
webview.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
webview.getSettings().setGeolocationEnabled(true);
webView.setWebChromeClient(new WebChromeClient() {
public void onGeolocationPermissionsShowPrompt(
String origin,
GeolocationPermissions.Callback callback) {
callback.invoke(origin, true, false);
}
});
webview.loadUrl(geoWebsiteURL);
}
对我有用。
我使用权限：
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_GPS" />
<uses-permission android:name="android.permission.ACCESS_ASSISTED_GPS" />
<uses-permission android:name="android.permission.ACCESS_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
请注意，在 Android 模拟器上，您必须使用以下命令设置位置geo fix.
