Java 如何使listView中的按钮在单击时工作？
我基本上是在创建一个购物车应用程序，我的listView是从我现有的数据库中填充的，它为您提供商品的商店、品牌、价格、描述和图像，每个图像的信息都存储在数据库中，并放入我创建的一个商品类中。因此，对于listView中显示的每个项目，它还将在每个图像的底部显示“添加到购物车”按钮，以便我可以单击该按钮并将其添加到购物车，这将是另一个活动。基本上，当我单击此按钮时，我希望运行一个查询，将该项目添加到我的数据库中，然后我将查询购物车活动中所有添加的项目，以便在那里显示我添加到购物车中的所有项目。因此，当我点击按钮时，我如何获得特定的项目并执行查询？它将如何获得该项目？我已经在下面发布了我的代码文件，任何帮助都会很好 shirtsActivity.javaJava 如何使listView中的按钮在单击时工作？,java,android,listview,android-listview,Java,Android,Listview,Android Listview,我基本上是在创建一个购物车应用程序，我的listView是从我现有的数据库中填充的，它为您提供商品的商店、品牌、价格、描述和图像，每个图像的信息都存储在数据库中，并放入我创建的一个商品类中。因此，对于listView中显示的每个项目，它还将在每个图像的底部显示“添加到购物车”按钮，以便我可以单击该按钮并将其添加到购物车，这将是另一个活动。基本上，当我单击此按钮时，我希望运行一个查询，将该项目添加到我的数据库中，然后我将查询购物车活动中所有添加的项目，以便在那里显示我添加到购物车中的所有项目。因此

您应该使用hirtsActivity.java文件中的最后一个函数：
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
}
});
listView.setOnItemClickListener（新的AdapterView.OnItemClickListener（）{
@凌驾
public void onItemClick（AdapterView父对象、视图、整型位置、长id）{
}
});
您可以选择特定的项目，感谢id参数。如果我这样做，那么按钮单击不起作用吗？那么，只有单击该项目中的listView，它才会起作用？那么，也许我可以在列表视图中为每个项目添加一些文本，使其看起来像一个按钮，然后使用您所说的内容？对不起，我没有仔细阅读您想要的内容。在toast之后，您可以通过以下方式使用按钮：addToCartButton.setOnClickListener（new View.OnClickListener（）{@Override public void onClick（View arg0）{//TODO自动生成的方法存根//来获取特定项toast.makeText（getContext（），“您的物品已添加到购物车中！”，Toast.LENGTH_LONG）.show（）；}}）；您可以通过向意图中添加额外内容来获取特定物品，例如item.getBrand（），item.getPrize（）请让我再次解释我的问题。因此，实际上，当我单击按钮时，我不想开始新的活动。好的，因此在我的列表视图中，它会显示每个服装项目，并显示其价格、品牌、si
