我试图开发能够检测BLE信号的应用程序，并显示其RSSI值（除了其他参数）。从现在开始，我能够检测BLE，并在的ListView 列出，但我坚持就当它已经检测到 BaseAdapter ，我已为的ListView开发。

I am trying to develop an app capable of detecting BLE signals and show its RSSI value (apart from other parameters). From now I am capable of detecting BLE and list it in a ListView but I am stuck on how to pass the parameter RSSI when it has been detected to the BaseAdapter that I have developed for the ListView.

这是code口用于检测BLE设备：

This is the code I used to detect the BLE device:

// Device scan callback.
private BluetoothAdapter.LeScanCallback mLeScanCallback =
    new BluetoothAdapter.LeScanCallback() {
        @Override
        public void onLeScan(final BluetoothDevice device, int rssi, byte[] scanRecord) {
            addDevice(device);
        }
    };

这是另一个类的地方是code以上实行的AddDevice code：

Here it is the addDevice code that is implemented in another class where it is the code above:

protected synchronized void addDevice(final BluetoothDevice device) {
    runOnUiThread(new Runnable() {
        @Override
        public void run() {
            mLeDeviceListAdapter.addDevice(device);
            mLeDeviceListAdapter.notifyDataSetChanged();
        }
    });
}

和决赛，在这里它是 BaseAdapter 我使用的的ListView ：

And final, here it is the BaseAdapter I use for the ListView:

public class LeDeviceListAdapter extends BaseAdapter {
private List<BluetoothDevice> data;
private Activity context;



public LeDeviceListAdapter(Activity context, List<BluetoothDevice> data) {
    this.data = data;
    this.context = context;
}

public synchronized void addDevice(BluetoothDevice device) {
    if(!data.contains(device) ){
    data.add(device);
    }
}

@Override
public int getCount() {
    return data.size();
}

@Override
public Object getItem(int position) {
    return data.get(position);
}

@Override
public long getItemId(int position) {
    return position;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    if (null == convertView) {
        LayoutInflater mInflater =
            (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        convertView = mInflater.inflate(R.layout.leaf_devices_list_item, null);
        convertView.setTag(new DeviceView(convertView));
    }
    DeviceView view = (DeviceView) convertView.getTag();
    view.init((BluetoothDevice) getItem(position), null);
    return convertView;
}

public class DeviceView {


    private TextView title;
    private TextView status;
    private TextView type;
    private TextView address;
    private TextView rssivalue;

    public DeviceView(View view) {
        title = (TextView) view.findViewById(R.id.device_name);
        status = (TextView) view.findViewById(R.id.device_status_txt);
        type = (TextView) view.findViewById(R.id.device_type_txt);
        address = (TextView) view.findViewById(R.id.device_address_txt);
        rssivalue = (TextView) view.findViewById(id.signal_intensity_txt);
    }

    public void init(BluetoothDevice device, Intent intent) {
        title.setText(device.getName());
        address.setText(device.getAddress());
        setType(device.getType());
        setStatus(device.getBondState());
    }
}

在rssivalue是的TextView 我要使用显示RSSI。

The "rssivalue" is the TextView I am going to use to show the RSSI.

我已经从我认为这是有关这一每一类采取了codeS的一部分。如果需要，我会提供code作为此case.Please重要的，有人帮我解决这个问题！

I have taken parts of the codes from each class that I thought it was relevant for this. If it is needed I will provide the code that are important for this case.Please, somebody help me to solve this problem!!!

推荐答案

从添加RSSI值 LeScanCallback ：

private BluetoothAdapter.LeScanCallback mLeScanCallback =
    new BluetoothAdapter.LeScanCallback() {
        @Override
        public void onLeScan(final BluetoothDevice device, int rssi, byte[] scanRecord) {
             yourBleAdapter.addDevice(device, rssi);
        }
    };  

在您的适配器，这将成为：

In your adapter, this becomes:

public void addDevice(BluetoothDevice device, int rssi) {
       //get device and its rssi locally here
    }

，你得到的RSSI值多数民众赞成。它是从样品code，我使用。作品。

thats where you get the rssi value from. It is from the sample code that i use. Works.
