我阅读是为了使用ListView,但是我应该怎么做呢?不是所有的行都是相等的,或者在任何情况下,中间有一些元素不等于所有其他行! 图像:


哇,这太糟糕了,请使用ListView而不是TableView,并根据您所在的分区动态添加行


我将扩展BaseAdapter来实现这一点,这显然是
列表视图的一个很好的候选者。正如我在评论中所说,您可以在
适配器中使用自定义
布局
。我不知道您是如何获取数据的,因此我无法确切说明如何检查,但在每一轮
getView()
中,您可以检查数据并决定显示/隐藏哪个
视图

只需使用
TextView
s等创建
layout
。。。每一行可能需要,看起来可能在垂直
LinearLayout
的内部,而水平
LinearLayout
在内部,或者只是一个
RelativeLayout
,然后根据需要将
可见性更改为
可见
/
消失

如果你不熟悉做这件事,那么你可以看看如何做


正如一篇评论中指出的,如果您有非常不同的
布局
,则可以在
适配器的
getView()
方法中使用不同的
布局
,这可能会使切换
可见性
成为一种糟糕的方法。这取决于您的数据和布局。

您必须使用MergeAdapter,您可以将不同的适配器合并到一个适配器。例如标题和值。我从StackOverflow获得了代码,但是我找不到主题,所以我将找到的代码粘贴到这里

在列表视图中,您将拥有一个接一个的adapterA和AndAperB,并正确地进行淋浴。这两个适配器可以具有不同的对象


再见。

你能发布一张它应该是什么样子的图片吗?这可能会有所帮助。使用
列表视图
您可以在
适配器
中使用自定义
布局
,并根据某个值决定显示/不显示某些
视图
s,如果这对您有效。您试图实现什么布局?截图就好了。同时使用如此多的视图会减慢您的速度app@codeMagic我添加图像;)请看我的答案,您需要扩展基本适配器,并根据您所在的部分执行一些条件逻辑,以确定要添加多少行或
ListView
还支持多行类型,而不是显示隐藏您可以添加对多行类型的支持,并从
getView()
中膨胀相应的行。我解决了!!谢谢我不知道我是否正确解决了…但是…我通过实现ListViewHaha解决了…不客气!如果您使用
ListView
解决了问题,并且它正常工作,那么您可能正确地解决了问题。这对于visbile/gone来说是一种不好的做法。我认为做@M-WaJeEh的事情更好said@MobileMon我不知道情况有多糟。这取决于它是如何实现的,以及数据是什么样的。我有一个使用它的
列表视图
,因为我有一行显示特定的
ImageButton
s,这取决于来自服务器的内容。但是,是的,这个建议也应该有效。关键是,无论哪种方式都需要使用自定义的
视图
    MergeAdapter adapter = new MergeAdapter();
AdapterA adapterA = new AdapterA(...);
AdapterB adapterB = new AdapterB(...);

adapter.addAdapter(adapterA);
adapter.addAdapter(adapterB);

listview.setAdapter(adapter);
