java - 使用特定对象上的 onItemClick 获取 listView 中项目的位置

Question

我有一个 ListView，其中包含从外部数据库获取的多个条目。每个条目都有一个图像按钮和其他对象。我想知道列表条目的位置，即用户单击图像按钮的位置。

是否有可能查看女巫对象，特别是用户点击的对象

this.getALlEntrysListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
            try {
                JSONObject entryClicked = jsonArray.getJSONObject(position);

？此代码位于我的 MainActivity 类中。

我在 Adapter 类中设置了每个条目的特定内容。

仅当用户单击图像按钮时获取 jsonArray 位置的另一种可能性是什么？

这是我的适配器类:

public class GetAllEntrysListViewAdapter extends BaseAdapter {

private JSONArray dataArray;
private Activity activity;
private static LayoutInflater inflater = null;

public GetAllEntrysListViewAdapter(JSONArray jsonArray, Activity a) {
    this.dataArray = jsonArray;
    this.activity = a;

    inflater = (LayoutInflater)this.activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}

@Override
public int getCount() {
    return this.dataArray.length();
}

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

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

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

    //set up convert view if it is not null
    ListCell cell;
    if (convertView == null) {
        convertView = inflater.inflate(R.layout.get_all_entry_list_view_cell, null);

        cell = new ListCell();
        cell.likes = (TextView) convertView.findViewById(R.id.listViewLikes);
        cell.note = (TextView) convertView.findViewById(R.id.listViewNote);
        cell.img = (ImageView) convertView.findViewById(R.id.listViewImg);
        cell.likeButton = (ImageButton) convertView.findViewById(R.id.likeButton);

        convertView.setTag(cell);

    }
    else {
        cell = (ListCell)convertView.getTag();
    }

    //change data of cell
    try {
        JSONObject jsonObject = this.dataArray.getJSONObject(position);
        cell.likes.setText("Likes: "+ jsonObject.getString("likes"));
        cell.note.setText(jsonObject.getString("note"));

        String img = jsonObject.getString("image");
        if (img.equals("img")) {
            cell.img.setImageResource(R.drawable.logo);
        }
    }
    catch (JSONException e) {
        e.printStackTrace();
    }
    return convertView;

}

private class ListCell {
    private TextView likes;
    private TextView note;
    private ImageView img;
    public ImageButton likeButton;

}

Answer 1

imageButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                RelativeLayout parent = (RelativeLayout)v.getParent();
                int position = listView.getPositionForView(parent);
                // position in listview
            }
        });
