android - 如何在自定义 ListView 中将特定 TextView 文本显示为 toast 消息？

Question

我有一个自定义 ListView ，每一行都有 3 个 TextView 这是我的自定义 ListView 适配器。如何在自定义 ListView 中将特定 TextView 文本显示为 toast 消息，以及如何在另一个 Activity 中发送该文本？

细节是我的getter和setter类

public class CustomListViewAdapter extends ArrayAdapter<Details> {

Context context;


public CustomListViewAdapter(Context context, int resourceId,
                             List<Details> items) {
    super(context, resourceId, items);
    this.context = context;
}



/*private view holder class*/
private class ViewHolder {
    //ImageView textView;
    TextView txtTitle;
    TextView txtTitle2;
    TextView txtDesc;
}

@SuppressLint("InflateParams")
public View getView(int position, View convertView, ViewGroup parent) {
    ViewHolder holder = null;
    //Details rowItem = (Details) getItem(position);
    Details rowItem = getItem(position);
    context
            .getSystemService(Activity.LAYOUT_INFLATER_SERVICE);

    if (convertView == null || convertView.getTag() == null) {

        LayoutInflater vi = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        convertView = vi.inflate(R.layout.list_item, null); //TODO: parent instead of null?

        holder = new ViewHolder();

        holder.txtDesc = (TextView) convertView.findViewById(R.id.desc);
        holder.txtTitle = (TextView) convertView.findViewById(R.id.title);
        holder.txtTitle2 = (TextView) convertView.findViewById(R.id.link);
        convertView.setTag(holder);


    }

    else if (rowItem.getResType().equals(vid)){

        holder = (ViewHolder) convertView.getTag();
    }
    if (holder != null) {
        holder.txtDesc.setText(rowItem.getResType());
        holder.txtTitle.setText(rowItem.getName());

        holder.txtTitle2.setText(rowItem.getUrl());

           }     

       return convertView;
    }

  }

您可以在您的自定义适配器中Override TextView 的OnClick 方法，并根据该方法在您的Toast 中显示文本 如下所示

txttitle.setOnClickListener(new View.OnClickListener() {
@覆盖
public void onClick(View v) {
Toast.makeText(getActivity(),
“点击 ListItem Number” + txttitle.getText().toString(), Toast.LENGTH_LONG)
。展示();
}
});
