Question

很简单。我唯一的代码是：

        final BroadcastReceiver mReceiver = new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) {

            String action = intent.getAction();
            if (BluetoothDevice.ACTION_FOUND.equals(action)){
                mDevice = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);
                Log.d(TAG,"Device "+mDevice.getName()+" Was Found");
            }
        }
    };

但在配对设备时不会调用此功能。为什么？

Answer 1

您好需要为广播接收器注册以下过滤器

ACTION_BOND_STATE_CHANGED

然后在onReceive

像这样添加它们

    if (BluetoothDevice.ACTION_BOND_STATE_CHANGED.equals(action)){
            mDevice = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);
            if (mDevice .getBondState() == BluetoothDevice.BOND_BONDED) {
            //means device paired
        }

   }

了解更多Bluetooth Device Page

int     BOND_BONDED     //Indicates the remote device is bonded (paired).
int     BOND_BONDING    //Indicates bonding (pairing) is in progress with the remote device.
int     BOND_NONE   //Indicates the remote device is not bonded (paired).

上次评论后

修改

你还需要添加

IntentFilter filter = new IntentFilter(BluetoothAdapter.ACTION_BOND_STATE_CHANGED);
 registerReceiver(mReceiver, filter);

请参考here您将找到如何连接列出蓝牙相关事件

Answer 3

你是否在清单中添加了权限？

<uses-permission android:name="android.permission.BLUETOOTH" />

Answer 4

从android 6.0及更高版本开始，您需要检查其他权限ACCESS_COARSE_LOCATION才能获取列表。没有这个，带有ACTION_FOUND的onReceive方法将不会调用。

BroadcastReceiver未调用蓝牙配对
