基于android studio的蓝牙模块
好的,根据你的需求,我可以帮你生成一份基础代码来实现通过蓝牙接收到分贝值的界面。以下是代码:
```
// 定义常量
private static final int REQUEST_ENABLE_BT = 1;
private static final UUID MY_UUID = UUID.fromString("00001101-0000-1000-8000-00805F9B34FB");
private static final String DEVICE_NAME = "YOUR_DEVICE_NAME"; // 替换成你的蓝牙设备名
// 定义变量
private BluetoothAdapter bluetoothAdapter;
private BluetoothDevice bluetoothDevice;
private BluetoothSocket bluetoothSocket;
private InputStream inputStream;
private OutputStream outputStream;
private boolean isConnected = false;
// 初始化蓝牙适配器
bluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
if (bluetoothAdapter == null) {
// 设备不支持蓝牙
return;
}
// 请求用户开启蓝牙
if (!bluetoothAdapter.isEnabled()) {
Intent enableBtIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE);
startActivityForResult(enableBtIntent, REQUEST_ENABLE_BT);
}
// 连接蓝牙设备
bluetoothDevice = bluetoothAdapter.getRemoteDevice(DEVICE_NAME);
bluetoothSocket = bluetoothDevice.createRfcommSocketToServiceRecord(MY_UUID);
bluetoothSocket.connect();
inputStream = bluetoothSocket.getInputStream();
outputStream = bluetoothSocket.getOutputStream();
isConnected = true;
// 创建和启动分贝值接收线程
DecibelThread decibelThread = new DecibelThread();
decibelThread.start();
// 分贝值接收线程定义
private class DecibelThread extends Thread {
private byte[] buffer;
private int bytes;
public void run() {
while (isConnected) {
try {
buffer = new byte[1024];
bytes = inputStream.read(buffer);
String decibel = new String(buffer, 0, bytes);
// 在界面上显示分贝值
runOnUiThread(new Runnable() {
@Override
public void run() {
// 更新UI代码
}
});
} catch (IOException e) {
e.printStackTrace();
break;
}
}
}
}
// 注意:以上代码仅提供了一个基础的框架,具体的实现还需要根据你的需求进行修改和完善。
