根据其在行中的位置设置文本视图单击onlistitemclicked从数据库中的SimpleCursorAdapter填充的列表视图我的自定义列表视图有一个名称的图像和文本视图和另一个不可见的文本视图，该视图将可见并设置为仅单击的行上的数字不同，但问题是当我单击任何行时，文本仅出现在第一行的视图中，无论我单击的行是什么，我尝试使用 set 和 get 方法，但我发现它用于基础适配器。并且可见的文本视图不是来自数据库，有人可以告诉我该怎么做

这是代码的一部分

我相信您需要做的是使用行视图容器的标记工具来识别它包含的文本视图，然后在侦听器中检索它以识别正确的文本视图。我这样做的方法是为包含行的视图使用一个持有者，这样您就可以访问您需要的任何内容。例如：

protected static class RowViewHolder {
    public TextView tvOne;
    public TextView tvTwo;
}

然后在你的 newView 方法中，填充持有者并将标签设置为它：

public View newView(Context context, Cursor cursor, ViewGroup parent) {
    LayoutInflater inflater = LayoutInflater.from(parent.getContext());
    View retView = inflater.inflate(R.layout.single_row_item, parent, false);

    RowViewHolder holder = new RowViewHolder();
    holder.tvOne = (TextView) retView.findViewById(R.id.name);
    holder.tvTwo = (TextView) retView.findViewById(R.id.txt_number);
    retView.setTag(holder);

    return retView;
}

在您的侦听器中，您可以访问正确的文本视图：

    public void onClick(View v) {
            ListView lv = (ListView) v.getParent();
            final int position = lv.getPositionForView((View) v.getParent());

            // get the RowViewHolder
            RowViewHolder holder = new RowViewHolder();
            holder = (RowViewHolder) ((View) v.getParent()).getTag();
            if(holder.tvOne.getVisibility() == View.INVISIBLE ) {
                holder.tvOne.setVisibility(View.VISIBLE);
            }
            else
            { 
                holder.tvOne.setVisibility(View.INVISIBLE);
            }
    }

抱歉，但我无法测试这段代码，但我希望它能给你一个指向该过程的指针。您不需要 RowViewHolder，但我已将其包含在内，以便您或其他人可以看到如何访问行内的多个视图。

您可能会发现此视频很有帮助ListView 的世界我想您会在大约 4:10 找到相关讨论，其中描述了视图如何被重新使用以及索引、位置等如何关联。

我还发现这个问题的答案之一对Android 很有帮助：ListView elements with multiple clickable button

有多种方法可以做到这一点。我建议的方式假设您有一个用于包含 CustConAdpterSelect 类的活动的代码模块。所以结构看起来像这样。

package com.example.totastest;

// imports

public class Copy_2_of_MainActivity extends Activity {

protected static class RowViewHolder
{
    public TextView tvOne;
    public TextView tvTwo;
}

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

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}

public class CustConAdpterSelect extends SimpleCursorAdapter
{
    // ...

    public CustConAdpterSelect(Context context, int layout, Cursor c, String[] from, int[] to)
    {
        super(context, layout, c, from, to, 0);
        // ...
    }

    public View newView(Context context, Cursor cursor, ViewGroup parent)
    {
        LayoutInflater inflater = LayoutInflater.from(parent.getContext());
        View retView = inflater.inflate(R.layout.lv_name_photo, parent, false);

        RowViewHolder holder = new RowViewHolder();
        holder.tvOne = (TextView) retView.findViewById(R.id.name);
        holder.tvTwo = (TextView) retView.findViewById(R.id.txt_number);
        holder.tvOne.setOnClickListener(tvOneLapOnClickListener);
        retView.setTag(holder);

        return retView;
    }

    @Override
    public void bindView(View v, final Context context, Cursor c)
    {
        // ...
    }

    @SuppressWarnings("unchecked")
    @Override
    public View getView(final int position, View convertView, ViewGroup parent)
    {
        // ...
    }

    private OnClickListener tvOneLapOnClickListener = new OnClickListener() {
        @Override
        // When the tvOne button is clicked, execute this code
        public void onClick(View v) {
                // get the RowViewHolder
                RowViewHolder holder = new RowViewHolder();
                // Get the holder for the row
