Question

我有一个Fragment Tabs寻呼机并使用了sherlockFragment，我需要搜索其中的其他蓝牙设备。但我无法注册接收器。我收到以下错误：方法registerReceiver（BroadcastReceiver，IntentFilter）未定义为Fragment_Bluetooth类型。我想知道我是否应该在另一个范围内使用registerReceiver？在哪里以及如何？这是我的代码：

public class Fragment_Bluetooth extends SherlockFragment {
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        // Create a BroadcastReceiver for ACTION_FOUND
        BroadcastReceiver mReceiver = new BroadcastReceiver() {
            public void onReceive(Context context, Intent intent) {
                String action = intent.getAction();
                // When discovery finds a device
                if (BluetoothDevice.ACTION_FOUND.equals(action)) {
                    // Get the BluetoothDevice object from the Intent
                    BluetoothDevice device = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);
                    // Add the name and address to an array adapter to ListView
                    mArrayAdapter.add(device.getName() + "\n" + device.getAddress());
                }
            }
        };
        // Register the BroadcastReceiver
        IntentFilter filter = new IntentFilter(BluetoothDevice.ACTION_FOUND);
        registerReceiver(mReceiver, filter); // Don't forget to unregister during onDestroy
    }
}

Answer 1

 getActivity().registerReceiver(mReceiver, filter); // Don't forget to unregister during onDestroy

或getSherlockActivity（）

 getSherlockActivity().registerReceiver(mReceiver, filter); // Don't forget to unregister during onDestroy

Android，在sherlockFragment中使用蓝牙
