ListView ，有没有办法增加高度？答案

【问题标题】：ListView , Is there a way to increase the height?ListView ，有没有办法增加高度？
【发布时间】：2019-06-02 10:10:58
【问题描述】：

我不知道为什么当我对文本视图施加约束时，它不会出现在我想要的确切位置，我认为这可能是列表视图高度问题将所有内容推到了一起

下图是问题显示：

这是我的适配器：

@Override
    public View getView(int position, View convertView, ViewGroup parent) {
        //Put the food_list_layout in the convertView
        if(convertView == null){
            convertView = View.inflate(context, R.layout.preorder_list_layout_orders,null);
        }

这是我的 XML 文件：

【讨论】：

嘿 John Joe，您提供的代码不会对每个屏幕尺寸都做出响应，让我解释一下原因：您经常使用固定尺寸，例如 android:layout_marginEnd="128dp。这些尺寸在 dp 中非常大- 在下面查看我的回答，相信它可以帮助您更好地了解 ConstraintLayout 的强大功能
此外，如果您想了解更多有关响应式布局的信息，我的回答 here 会更详细。

【解决方案2】：

您的视图使用固定大小，这使您的屏幕无响应。

如果你想实现响应式布局不要使用固定大小，你可以使用ConstraintLayout，但带有android:layout_width="0dp"、android:layout_width="wrap_content"属性和一些Guidelines。

这是您想要的布局的示例：
