通过单击 listView 项目配对两个蓝牙设备，Android

Question

我对 java 上 android 的编程还比较陌生，无法弄清楚如何通过单击包含新发现列表的 listView 的项目来配对两个设备设备。

我已经创建了一个包含一组新发现的设备的列表视图，这里是我的点击事件代码的一部分：`

public class MainActivity extends AppCompatActivity {

ListView newListView; // listView containing newly discovered devices
ArrayAdapter<String> mNewDevicesArrayAdapter;
BluetoothAdapter mBluetoothAdapter;


@Override
protected void onCreate(Bundle savedInstanceState) {


    /* Variables definition */

    mNewDevicesArrayAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1);
    newListView = (ListView) findViewById(R.id.new_lv);

    // New Devices List View item click
    newListView.setClickable(true);

    newListView.setOnItemClickListener(new AdapterView.OnItemClickListener(){
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {

        // some code must go here, but I can't figure out which one 


        }
    });

   }

在此先感谢您的帮助！！！

Answer 1

你有一个字符串列表，是的，在适配器中？

您可以从 BluetoothAdapter

中获取一个 BluetoothDevice 对象

newListView.setOnItemClickListener(new AdapterView.OnItemClickListener(){
    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {

        String address = mDevicesAdatper.getItem(position);
        BluetoothDevice btDevice = mBluetoothAdapter.getRemoteDevice(address);

        // TODO: Pair

    }
});

处理配对设备的许多细节都在 the documentation
