我的功能连接需要一个BluetoothDevice参数 我希望能够从ListView onClick()获取它,但我只设法得到一个名称或地址。
我似乎需要从Set&#34;配对设备&#34;中获取蓝牙设备
我正在使用ConnectionChatService.java
类。
答案 0 :(得分:0)
你有一个只读字符串的原始适配器
实际存储BluetoothDevice in a custom adapter
列表从自定义类开始
public class BluetoothArrayAdapter extends ArrayAdapter<BluetoothDevice> {
// implement getView
然后你可以使用它,例如,在点击监听器中获取点击位置的项目
final BluetoothArrayAdapter arrayAdapter = new BluetoothArrayAdapter(MainActivity.this, R.layout.your_bluetooth_layout);
arrayAdapter.addAll(mBluetoothAdapter.getBondedDevices());
lv.setAdapter(arrayAdapter);
lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
bluetoothChatService.start();
bluetoothChatService.connect(arrayAdapter.getItem(i));
}
});
