onBeaconServiceConnect不被调用 [英] onBeaconServiceConnect not called

问题描述

像以前一样，我使用Android信标库，

As before, I work with Android Beacon Library,

它已经工作了，我可以通过BLE-低功耗蓝牙找到信标，

It already worked and I can found out beacon via BLE - Bluetooth low energy,

但是现在，在更新到最新版本的库之后，现在方法 onBeaconServiceConnect（）不再运行。

But now, after updated to latest version of library, now method onBeaconServiceConnect() not run anymore.

请告诉我要使其正常工作需要做什么，

Please tell me what I need to do to make it works,

谢谢，

p / s：代码：

public static String UUID = "01122334-4556-6778-899a-abbccddeeff0";

ANSWER

因为我使用 Fragment 而不是 Activity 作为库中的示例代码。

Since I used Fragment not Activity as sample codes from the library.

所以我需要做这些更改：

So I need do these changes :

@Override
public Context getApplicationContext() {
    return getActivity().getApplicationContext();
}

@Override
public void unbindService(ServiceConnection serviceConnection) {
    getActivity().unbindService(serviceConnection);
}

@Override
public boolean bindService(Intent intent, ServiceConnection serviceConnection, int i) {
    return getActivity().bindService(intent, serviceConnection, i);
}

推荐答案

如果要实现< 片段中的code> BeaconConsumer 接口（而不是 Activity ， Service 或 Application 实例），则需要链接所有方法。像这样：

If you are implementing the BeaconConsumer interface in a Fragment (and not an Activity, Service or Application instance), you need to chain all of the methods. Like this:

@Override
public Context getApplicationContext() {
    return getActivity().getApplicationContext();
}

@Override
public void unbindService(ServiceConnection serviceConnection) {
    getActivity().unbindService(serviceConnection);
}

@Override
public boolean bindService(Intent intent, ServiceConnection serviceConnection, int i) {
    return getActivity().bindService(intent, serviceConnection, i);
}
