Android:如何隐藏 ListView 项 [英] Android: How to hide a ListView Item

问题描述

如何隐藏 ListView 中的项目或至少将其高度设置为零?

How can you hide an item in a ListView or at least set its height to zero?

我已经尝试将视图的可见性设置为 GONE，但它仍然保持项目的空间(高度).

I have tried setting the visibility of the View to GONE but it still maintains the item's space (height).

推荐答案

重新提出一个老问题，但我刚刚遇到了这个问题，我想根据列表数据之外的条件暂时隐藏列表项.我最终做的是在 xml 中创建一个空项目"布局，并根据我的标准而不是 getView() 中的转换视图返回该布局...

Ressurecting an old question, but I just had this issue where I wanted to hide list items temporarily based upon criteria outside of the list data. What I ended up doing was creating a "null item" layout in xml and returned that based upon my criteria instead of the convert view in getView()...

我没有返回 convertView，而是返回了我的 null_item...

instead of returning the convertView, I returned my null_item...

return inflater.inflate(R.layout.null_item, null);

null_item.xml:

null_item.xml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" >

</LinearLayout>
