安卓：如何找出蓝牙设备的连接名称？ [英] Android: How to find out name of the bluetooth device connected?

问题描述

基本上我试着在这里两件事情，我试着开始时，我的蓝牙设备连接到特定设备的烤面包（所以需要检查是否是特定的蓝牙名称），如果是这样的特定设备，然后我想当连接到特定的蓝牙设备显示敬酒。我也想展示敬酒时，我的蓝牙断开连接到特定的蓝牙设备。
这里是我的code：
在的manifest.xml

Basically im trying 2 things here, Im trying to start a toast when my bluetooth device is connected to a particular device (so need to check if that is the particular bluetooth name), if that is the particular device then i want to show a toast when connected to that particular bluetooth device. I also want to show a toast when my bluetooth is disconnected to that particular bluetooth device. Here's my code: in manifest.xml

<uses-permission android:name="android.permission.BLUETOOTH" />
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />

<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>  

类的code：

公共类MyBluetoothReceiver扩展广播接收器{

public class MyBluetoothReceiver extends BroadcastReceiver {

@Override
public void onReceive(Context context, Intent intent) {

     Toast.makeText(context, "RECEIVER CALLED!!", Toast.LENGTH_LONG).show();


    if(intent.getAction().equals(
      "android.bluetooth.BluetoothDevice.ACTION_ACL_CONNECTED")){

       // code for Bluetooth connect

       Toast.makeText(context, "CONNECTED!!", Toast.LENGTH_LONG).show();
    }

    if(intent.getAction().equals(
      "android.bluetooth.device.action.ACL_DISCONNECTED")){

      //code for Bluetooth disconnect;
      Toast.makeText(getApplicationContext(),"DISCONNECTED",Toast.LENGTH_LONG).show();
    }
}
}

在我的code即时得到接收器被称为土司正确，甚至断开的敬酒也正在而是连接永远不会奏效敬酒。

In my code im getting receiver called toast properly and even the toast for disconnected is also working but toast of connected never works.

请让我知道为什么关连敬酒不工作，当连接到特定设备如何使这个code的工作（我不想显示此敬酒所有设备）

推荐答案

您广播接收机更改为：

private final BroadcastReceiver mReceiver = new 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)) {
            // Get the BluetoothDevice object from the Intent
            BluetoothDevice device = intent
                    .getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);

                          //you can get name by device.getName()

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

        }
    }
 };
