代码检查gps可用？
public static boolean areProvidersEnabled(Context context) {?
? ? ContentResolver cr = context.getContentResolver();?
? ? String providersAllowed = Settings.Secure.getString(cr, Settings.Secure.LOCATION_PROVIDERS_ALLOWED);?
? ? return providersAllowed != null && providersAllowed.length() > 0;?
}?

如果没有设置 那你可以提醒用户设置打开
Intent intent = new Intent(Settings.ACTION_SECURITY_SETTINGS);?
startActivity(intent);?
