我正在尝试在Android中获取当前连接的蓝牙设备.但我只需要配对设备列表,adapter.getBondedDevices();我需要当前连接的设备.我怎么能得到这个.请有人帮助我实现这一目标.提前致谢.

Answer 1

这很直截了当.Android 蓝牙管理器有方法

getConnectedDevices()

实施如下:

BluetoothManager manager = (BluetoothManager) getSystemService(BLUETOOTH_SERVICE);
    List<BluetoothDevice> connected = manager.getConnectedDevices(GATT);
    Log.i("Connected Devices: ", connected.size()+"");

如果您想了解有关已连接设备的更多详细信息,可以使用上面的列表方法将其置于for循环中,并获取所连接的每个蓝牙设备的内部详细信息.

将其添加到您的清单文件中

<receiver android:name=".MyBluetoothReceiver" >
<intent-filter>
<action android:name="android.bluetooth.device.action.ACL_CONNECTED" />
<action android:name="android.bluetooth.device.action.ACL_DISCONNECTED" 
/>
<action 
android:name="android.bluetooth.device.action.ACL_DISCONNECT_REQUESTED" 
/>           
</intent-filter>  
</receiver>  

添加该类

public class MyBluetoothReceiver extends BroadcastReceiver {
 @Override
public void onReceive(Context context, Intent intent) {
    String action = intent.getAction();

    // When discovery finds a device
    if (BluetoothDevice.ACTION_ACL_CONNECTED.equals(action)) {

    BluetoothDevice device = intent
                .getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);

     Toast.makeText(getApplicationContext(),device.getName() +" CONNECTED",Toast.LENGTH_LONG).show();

    } else if (BluetoothAdapter.ACL_DISCONNECTED
            .equals(action)) {

    }
}
}
