蓝牙配对未调用BroadcastReceiver

Question

很简单的。我唯一的代码是这样的：

        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");
            }
        }
    };

但这在我配对设备时不会被调用。为什么呢？

嗨，您需要注册您的广播接收器以使用以下过滤器

ACTION_BOND_STATE_CHANGED

然后在onReceive

像这样添加他们

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

   }

在此处了解更多信息蓝牙设备页面

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). 

编辑：最后评论之后

您还需要添加

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