Android 查找附近的蓝牙设备
示例
BluetoothAdapter首先声明。
BluetoothAdapter mBluetoothAdapter;
现在创建一个BroadcastReceiver用于ACTION_FOUND
private final BroadcastReceiver mReceiver = new BroadcastReceiver() {
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
//找到设备
if (BluetoothDevice.ACTION_FOUND.equals(action))
{
//从Intent获取BluetoothDevice对象
BluetoothDevice device = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);
//将名称和地址添加到阵列适配器以显示在列表中
mArrayAdapter.add(device.getName() + "\n" + device.getAddress());
}
}
};注册BroadcastReceiver
IntentFilter filter = new IntentFilter(BluetoothDevice.ACTION_FOUND); registerReceiver(mReceiver, filter);
然后通过致电开始发现附近的蓝牙设备startDiscovery
mBluetoothAdapter.startDiscovery();
不要忘记注销BroadcastReceiver内部onDestroy
unregisterReceiver(mReceiver);
