android 蓝牙设备断开 android – 如何检查设备的蓝牙连接是否断开？

我想知道我与设备的蓝牙连接何时断开连接.我发现这个要检查：

IntentFilter filter1 = new IntentFilter(BluetoothDevice.ACTION_ACL_CONNECTED);

IntentFilter filter2 = new IntentFilter(BluetoothDevice.ACTION_ACL_DISCONNECT_REQUESTED);

IntentFilter filter3 = new IntentFilter(BluetoothDevice.ACTION_ACL_DISCONNECTED);

this.registerReceiver(mReceiver, filter1);

this.registerReceiver(mReceiver, filter2);

this.registerReceiver(mReceiver, filter3);

//The BroadcastReceiver that listens for bluetooth broadcasts

mReceiver = new BroadcastReceiver() {

@Override

public void onReceive(Context context, Intent intent) {

String action = intent.getAction();

BluetoothDevice device = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);

if (BluetoothDevice.ACTION_FOUND.equals(action)) {

//Device found

}
