LinearLayout内的多个RelativeLayout显示错误

我有一个MoodTracker应用程序，该应用程序每24小时将每天的情绪存储到首选项中，并显示最近7天情绪的历史记录。
我的问题如下：
我的历史记录布局在LinearLayout中有7个相对布局（每天一个）。
预览是完美的，一个又一个。但是当我运行应用程序时 我只能看到4/7的布局，每个布局都比预期的要大得多... 这是我的代码：

预先感谢

问题出在您的RelativeLayouts中：

let categories = [{id: 1,name: "category 1",items: [19993, 99737]},{id: 2,name: "category 2",items: [70264, 65474, 07078]},{id: 3,name: "category 3",items: [76765]}]
let items = [{id: 19993, name: "item 1"},{id: 70264, name: "item 2"},{id: 99737, name: "item 3"},   {id: 65474, name: "item 4"},{id: 76765, name: "item 5"},{id: 07078, name: "item 6"},]

let op = categories.reduce((op, {name, items:cartItems}) => {
  cartItems.forEach(key => {
    let value = items.find(({id}) => id === key)
    if(value){
      op[name] = op[name] || []
      op[name].push(value)
    }
  })
  return op
},{})

console.log(op)

如果您使用的是layout_weight，并且您希望7个RelativeLayouts占用相等的空间，则应设置layout_height =“ 0”：

android:layout_height="match_parent"
android:layout_weight="1"

答案 1 :(得分：0)

在每个RelativeLayout中，进行以下更改：

  1. 将每个“ android：layout_height”更改为0
  2. 添加“ layout_weight”属性并将其值设置为1

答案 2 :(得分：0)

请勿在视图上使用android:layout_weight或固定大小-可能适用于像这样的小布局，但在大布局中，可能会影响您的屏幕性能；在视图上使用固定大小时，它没有响应到所有屏幕尺寸。

最好使用constraintlayout以获得对所有设备都有响应的漂亮屏幕：
