如何等待直到蓝牙断开android
[英]how to wait till bluetooth is disconnected android
问题描述
I am switching off the bluetooth on my activity finish. 
我要在活动结束时关闭蓝牙。 As the calls to disconnect bluetooth are asynchronous, it is going to another activity before completely disconnecting the bluetooth. 由于断开蓝牙的调用是异步的，因此在完全断开蓝牙连接之前，它将转到另一个活动。 This behaviour is making the app to hang till the bluetooth is disconnected. 此行为使应用程序挂起，直到蓝牙断开连接。 So, I am planning to display dialog till bluetooth is disconnected. 因此，我打算显示对话框直到蓝牙断开。 Any idea on how to achieve it? 关于如何实现它的任何想法？

You should probably use a Broadcast Receiver with BluetoothDevice.ACTION_ACL_DISCONNECTED . 您可能应该将Broadcast Receiver与BluetoothDevice.ACTION_ACL_DISCONNECTED 。
Refer : http://developer.android.com/reference/android/bluetooth/BluetoothDevice.html#ACTION_ACL_DISCONNECTED 请参阅： http : //developer.android.com/reference/android/bluetooth/BluetoothDevice.html#ACTION_ACL_DISCONNECTED
