这是我要在其中实现 onClickListener 的类：

private void updateUserListView(DatabaseHandler dbh) {
    List<User> users = dbh.getAllUsers();
    ListView listView = (ListView) findViewById(R.id.userslistview);
    listView.setAdapter(new UserArrayAdapter(BeerFriendActivity.this, users));      
}

适配器代码为：

public class UserArrayAdapter extends ArrayAdapter<User> {
private final Context context;
private final List<User> values;

public UserArrayAdapter(Context context, List<User> values) {
    super(context, R.layout.userrow, values);
    this.context = context;
    this.values = values;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    final int pos = position;
    final Context con = context;
    LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    View rowView = inflater.inflate(R.layout.userrow, parent, false);
    Button button = (Button) rowView.findViewById(R.id.userrowbutton);
    TextView textView = (TextView) rowView.findViewById(R.id.userrownametext);
    textView.setText(values.get(position).getName());

    button.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            Intent myIntent = new Intent(context,BeerSearchActivity.class); 
            Bundle b = new Bundle();
            b.putInt("id", values.get(pos).getId());
            myIntent.putExtras(b); //Put your id to your next Intent
            con.startActivity(myIntent);
        } 
    });

    User user = values.get(position);
    return rowView;
}}

我已经尝试实现点击器，但我得到的只是一堆错误。我已经阅读了许多教程和类似的问题，但似乎没有一个答案适合我的情况，或者我不太了解它们。任何帮助将非常感激！

ListView 并没有真正设置为其中包含可点击控件，onClick() 方法使用的是 touchEvent 而不是行。不过有一个解决方法，您可以在 XML 中为您的按钮或其他可点击元素指定一个自定义回调，就像在这个示例中一样。

The problem is in focus of button.You should use other View instead of button in each row (ImageView for example) and set onItemClickListener to your listView
