获取有关OnItemClick ListView项的值 [英] Get value of item on OnItemClick Listview

问题描述

我试图让在一个列表视图自定义适配器所选项目的价值。我尝试用以下code：

I try to get the value of a selected Item within a custom adapter on a listview. I try this with following code:

public void onItemClick(AdapterView<?> parent, View v,
                        int position, long id) {

                    View curr = parent.getChildAt((int) id);
                    TextView c = (TextView)curr.findViewById(R.id.tvPopUpItem);
                    String playerChanged = c.getText().toString();

                    Toast.makeText(Settings.this,playerChanged, Toast.LENGTH_SHORT).show();

                }

在开始的时候，如果我点击，该值是好的，但一旦我滚动，我点击另一个项目，我得到的点击项目...任何想法是什么原因造成这种错误的价值？

At the beginning, if I click, the values are good, but once I scrolled and I click on another Item, I get the wrong value of that clicked item... Any idea what is causing this?

推荐答案

参数 v 是当前行。所以使用：

The parameter v is the current row. so use:

public void onItemClick(AdapterView<?> parent, View v, int position, long id) {
    TextView c = (TextView) v.findViewById(R.id.tvPopUpItem);
    String playerChanged = c.getText().toString();

    Toast.makeText(Settings.this,playerChanged, Toast.LENGTH_SHORT).show();
}

（或者你可以使用 getChildAt（位置）但这会慢一些。）

了解您可能能够简化这更取决于你的布局。

Understand you might be able to simplify this more depending on your layout.
