Java GPS定位已启用，但可以'；找不到设备位置

即使启用了位置，应用程序仍停留在白色对话框中。 关于位置责任，有两个文件如下所述

提醒Activity.java：

上述相同内容在rementactivity.java中编写如下：

提醒Activity.java：

这是一个注册的屏幕&这个位置在某些设备上有效，但在所有设备上不起作用（正如我测试的那样）。 即使启用了位置，应用程序仍停留在白色对话框中

如何解决这个问题。

提前感谢。

如果您只想检查应用程序在前台时是否启用了位置，请使用下面的方法

启动“位置源设置”后，关闭对话框并在“活动”中显示一些刷新按钮。单击“刷新”按钮时，再次重新创建“活动”

     public void onClick(@SuppressWarnings("unused") final DialogInterface dialog, @SuppressWarnings("unused") final int id) {
                            startActivity(new Intent(android.provider.Settings.ACTION_LOCATION_SOURCE_SETTINGS));
                             finish();
                        }

     //in your activity
        public void onRefresh() {
             reCreate();
            }
    }

使用服务不断检查有关Gps的信息。@IDLERNER如何做，兄弟…请指导我

            final AlertDialog.Builder builder = new AlertDialog.Builder(this);
