如何使用自定义适配器单击列表视图中的项目

// 自定义适配器类
public class CustomAdapter extends BaseAdapter {
    private List<String> dataList;
    private Context context;

    public CustomAdapter(Context context, List<String> dataList) {
        this.context = context;
        this.dataList = dataList;
    }

    @Override
    public int getCount() {
        return dataList.size();
    }

    @Override
    public Object getItem(int position) {
        return dataList.get(position);
    }

    @Override
    public long getItemId(int position) {
        return position;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        ViewHolder viewHolder;

        if (convertView == null) {
            convertView = LayoutInflater.from(context).inflate(R.layout.list_item, parent, false);
            viewHolder = new ViewHolder();
            viewHolder.textView = convertView.findViewById(R.id.text_view);
            convertView.setTag(viewHolder);
        } else {
            viewHolder = (ViewHolder) convertView.getTag();
        }

        final String data = dataList.get(position);
        viewHolder.textView.setText(data);

        // 设置点击事件
        convertView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                // 处理点击事件
                Toast.makeText(context, "点击了：" + data, Toast.LENGTH_SHORT).show();
            }
        });

        return convertView;
    }

    static class ViewHolder {
        TextView textView;
    }
}

// 在活动或片段中使用自定义适配器
public class MainActivity extends AppCompatActivity {
    private ListView listView;
    private List<String> dataList;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        listView = findViewById(R.id.list_view);
        dataList = new ArrayList<>();
        // 添加数据到数据源

        CustomAdapter adapter = new CustomAdapter(this, dataList);
        listView.setAdapter(adapter);

        // 设置列表项的点击事件
        listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                // 处理点击事件
                String data = dataList.get(position);
                Toast.makeText(MainActivity.this, "点击了：" + data, Toast.LENGTH_SHORT).show();
            }
        });
    }
}
