监听蓝牙连接的状态

之前写的是监听蓝牙是否打开。这篇文章简单的介绍蓝牙的连接状态监听。忘记是哪位博主写的了。本人简单的整理下。代码其实就一个工具类而已：

package com.tools;

import android.bluetooth.BluetoothDevice;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.util.Log;

import com.service.PlayService;
import com.shouchiji.ConnectDev;
import com.ui.activity.MainActivity;
import com.shouchiji.R;

import static com.tools.Utils.page;
import static com.ui.activity.MainActivity.ifExit;

/**
 * 监听蓝牙的连接状态
 */
public class BlueToothReceiver extends BroadcastReceiver {

    private String btMessage = "";
    //监听蓝牙状态

    @Override
    public void onReceive(Context context, Intent intent) {
        String action = intent.getAction();
        BluetoothDevice device = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);
        //连接
        if (BluetoothDevice.ACTION_ACL_CONNECTED.equals(action)) {
            btMessage = device.getName();//蓝牙的名字
            //已经连接，开始你的操作，我是用了播放音乐的方式提醒客户
        } else if (BluetoothDevice.ACTION_ACL_DISCONNECTED.equals(action)) {
            Log.e("断开", "onReceive: " + device.getName());//蓝牙的名字
            btMessage = device.getName() + "蓝牙连接已断开！！";
            //已经断开，开始你的操作，我是用了播放音乐的方式提醒客户，然后在activity里写了一个方法，继续连接。
           
        }
    }
}

清单文件：
