蓝牙PTT触发安卓广播代码

下面是蓝牙PTT触发安卓广播的代码：

private final BroadcastReceiver mBroadcastReceiver = new BroadcastReceiver() {
    @Override
    public void onReceive(Context context, Intent intent) {
        String action = intent.getAction();

        if (BluetoothHeadset.ACTION_AUDIO_STATE_CHANGED.equals(action)) {
            int state = intent.getIntExtra(BluetoothHeadset.EXTRA_STATE, -1);
            if (state == BluetoothHeadset.STATE_AUDIO_CONNECTED) {
                // PTT button pressed
                Intent i = new Intent("com.example.PTT_BUTTON_PRESSED");
                sendBroadcast(i);
            } else if (state == BluetoothHeadset.STATE_AUDIO_DISCONNECTED) {
                // PTT button released
                Intent i = new Intent("com.example.PTT_BUTTON_RELEASED");
                sendBroadcast(i);
            }
        }
    }
};

以上代码是一个广播接收器，用于接收蓝牙耳机的状态改变事件。如果耳机连接成功并且蓝牙PTT按钮被按下，会发送一个名为"com.example.PTT_BUTTON_PRESSED"的广播。如果耳机断开连接或者PTT按钮被释放，会发送一个名为"com.example.PTT_BUTTON_RELEASED"的广播。你可以根据自己的需求修改广播的名称和相应的操作。
