我很少来这里,因为我的大部分问题都是通过示例和示例等解决的。我不坏。现在我的问题是我无法弄清楚到底发生了什么。所以我买了这台打印机,我得到了 SDK,在 sdk 中,一旦我加载它,我必须按下连接,它配对并我打入引脚 (0000),一旦完成,我就会显示测试按钮并打印字符串等。

我想要它做的是,连接到打印机(自动或使用针,无论如何)然后按“下一个活动”并能够在下一个活动中打印我想要使用蓝牙打印机进行的任何活动。但是当下一个活动加载时,连接关闭,我无法使用打印机,除非我将连接方法一起创建到该活动中,我需要一遍又一遍地配对设备。所以这是我得到的SDK。我真的希望有人能帮助我,因为我快疯了,我尝试使用 getbondeddevices,但我认为我不够聪明......所以就这样吧。也许有人可以看到打印机如何连接以及我如何在整个活动中共享它?

甚至可能是关于如何配对设备然后在下一个活动中使用它的教程......任何帮助都会很棒
