问题描述

I have two LinearLayout like below structure. 我有两个类似于以下结构的LinearLayout 。 

<LinearLayout
    android:orientation="vertical">

        <LinearLayout
        android:id="@+id/kanji"
        android:layout_width="match_parent"
        android:layout_height="120dp"/>

        <LinearLayout
        android:id="@+id/goi"
        android:layout_width="match_parent"
        android:layout_height="120dp">

</LinearLayout>

The problem is the second LinearLayout (id= goi ) is not showing as expected. 问题是第二个LinearLayout （id = goi ）未按预期显示。 I tried changing the top layout to RelativeLayout but it didn't work also. 我尝试将顶部布局更改为RelativeLayout但它也不起作用。

Why is this occuring? 这是为什么会发生的？

Linearlayout missing in inside other LinearLayout 其他LinearLayout内部缺少Linearlayout

Your root LinearLayout hight is 120dp and you have 2 child LinearLayout with same hight of 120dp so there is no space for second LinearLayout to visible 您的根LinearLayout高度是120dp并且您有2个子LinearLayout ，其高度为120dp因此第二个LinearLayout没有空间可见

Solution 解

Change your root LinearLayout hight to android:layout_height="wrap_content" it will work 将你的根LinearLayout hight更改为android:layout_height="wrap_content"它将起作用

The parent LinearLayout has a height of 120px as does the first child of it. 父LinearLayout的高度为120px，与其第一个子节点一样。 So the first child LinearLayout fills up all the height of the parent layout. 因此，第一个子LinearLayout填充了父布局的所有高度。

You can either increase the height of parent LinearLayout or make it "wrap_content" so it dynamically adjusts its height to the content it has. 您可以增加父LinearLayout的高度或使其成为“wrap_content”，以便动态调整其高度到其拥有的内容。

It is happening because your top layout has fixed height 它正在发生，因为您的顶部布局具有固定的高度 

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="120dp"
    android:background="@drawable/rounded_corner_2"
    android:layout_margin="10dp"
    android:orientation="vertical">

update this into 将此更新为 

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@drawable/rounded_corner_2"
    android:layout_margin="10dp"
    android:orientation="vertical">

The height of your parent LinearLayuot and child LinearLayouts is 120dp. 您的父LinearLayuot和子LinearLayouts的高度为120dp。 You will need to change the height of child layouts to fit into the parent layout 您需要更改子布局的高度以适合父布局

您可以使用指令<include></include>但我建议在约束布局上执行实现
