Android经典蓝牙工具类

已完成:

  • 开启蓝牙
  • 关闭蓝牙
  • 扫描蓝牙设备
  • 连接配对
  • 发送数据
  • 接收数据
  • 获取已配对设备

TODO:

  • 接收文件
  • 功能优化、性能优化、BUG清扫

最近在做一个带有蓝牙打印机的项目,借此完成这个库的开发

导入

implementation 'com.sdwfqin.cbt:cbt:1.1.1'

使用

  1. 初始化

    public class BaseApp extends Application {
        @Override
        public void onCreate() {
            super.onCreate();
            CbtManager
                    .getInstance()
                    // 初始化
                    .init(this)
                    // 是否打印相关日志
                    .enableLog(true);
        }
    }
    
    /**
     * 设置自定义UUID
     *
     * @param uuid
     * @return BleManager
     */
    public CbtManager setUUID(String uuid) {
        CbtConstant.CBT_UUID = UUID.fromString(uuid);
        return this;
    }
    
    /**
     * 设置自定义服务名称
     *
     * @param name
     * @return BleManager
     */
    public CbtManager setServiceName(String name) {
        CbtConstant.CBT_NAME = name;
        return this;
    }
  2. 开启蓝牙

    CbtManager
        .getInstance()
        .enableBluetooth(isOn -> {
            if (isOn) {
                Toast.makeText(mContext, "蓝牙已开启", Toast.LENGTH_SHORT).show();
            }
        });
  3. 关闭蓝牙

    CbtManager
        .getInstance()
        .disableBluetooth(isOn -> {
            if (!isOn) {
                Toast.makeText(mContext, "蓝牙已关闭", Toast.LENGTH_SHORT).show();
            }
        });
  4. 扫描设备

    CbtManager
        .getInstance()
        .scan(new ScanCallback() {
            @Override
            public void onScanStart(boolean isOn) {
                // 开始扫描
            }
    
            @Override
            public void onScanStop(List<BluetoothDevice> devices) {
                // 搜索完成
                mScanListAdapter.setNewData(devices);
            }
    
            @Override
            public void onFindDevice(BluetoothDevice device) {
                // 搜索到设备
                mScanListAdapter.addData(device);
            }
        });
  5. 连接设备

    BluetoothDevice item = mScanListAdapter.getItem(position);
    CbtManager
        .getInstance()
        .connectDevice(item, new ConnectDeviceCallback() {
            @Override
            public void connectSuccess(BluetoothSocket socket, BluetoothDevice device) {
                // 连接成功
                Toast.makeText(mContext, "连接成功!", Toast.LENGTH_SHORT).show();
            }
    
            @Override
            public void connectError(Throwable throwable) {
                // 连接失败
                Toast.makeText(mContext, "连接失败:" + throwable.getMessage(), Toast.LENGTH_SHORT).show();
            }
        });
  6. 发送数据

    byte[] data;
    try {
        data = (mData.getText().toString() + "\n\n\n\n\n\n").getBytes("GBK");
    } catch (UnsupportedEncodingException e) {
        e.printStackTrace();
        return;
    }
    
    List<byte[]> bytes = new ArrayList<>();
    bytes.add(BYTES[0]);
    bytes.add(BYTES[1]);
    bytes.add(data);
    
    CbtManager
        .getInstance()
        .sendData(bytes, new SendDataCallback() {
            @Override
            public void sendSuccess() {
                // 发送成功
            }
    
            @Override
            public void sendError(Throwable throwable) {
                // 发送失败
                Toast.makeText(SendDataActivity.this, throwable.getMessage(), Toast.LENGTH_SHORT).show();
            }
        });
  7. 蓝牙服务端(回调接口目前是在子线程中调用)

    CbtManager
        .getInstance()
        .startServiceListener(new ServiceListenerCallback() {
            @Override
            public void onStartError(Throwable throwable) {
                // 发生错误
                CbtLogs.e(throwable.getMessage());
            }
    
            @Override
            public void onDataListener(String s, BluetoothDevice device) {
                // 获取到数据
                runOnUiThread(() ->
                        mReceiveDataAdapter.addData(new ReceiveDataModel(device, s))
                );
            }
        });
