如何判断是否在使用Titanium的Android上启用了GPS

Question

我正在使用Titanium的Android 3.2+应用程序.至关重要的是,我能够确定设备是否启用了GPS.根据Titanium API参考,由于新的"被动"位置提供程序,Ti.Geolocation.locationServicesEnabled将始终在Android 2.2+上返回true.有没有其他方法可以确定GPS是否真正启用？

谢谢.

我认为这段代码应该适合你：

//check to see if we have GPS capabilities
if(Titanium.Geolocation.isLocationProviderEnabled(Titanium.Geolocation.PROVIDER_GPS,     Titanium.Geolocation.ACCURACY_BEST) == false) {
var alertDlg = Titanium.UI.createAlertDialog({
    title:'MileTrackGPS', 
    message:'GPS is OFF.  Enable it in Settings.',
    buttonNames: ['Cancel', 'Open Settings']
});
alertDlg.cancel = 0;

alertDlg.addEventListener('click', function(e){
    if(!e.cancel) {
        //open up the settings page
        var settingsIntent = Titanium.Android.createIntent({
            action: 'android.settings.LOCATION_SOURCE_SETTINGS'
        });
        activity.startActivity(settingsIntent);
    }
    else {
        //close the window to exit
        win.close();
    }
});

alertDlg.show();
}
