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

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

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))
               );
           }
       });
