如何多次包含相同的布局

Question

嗨，我有一个我想多次使用的布局

但是当我使用include时它只出现一次，我在网上看了但无法得到答案

你能建议我在这里做错了什么吗

提前致谢 R

我的常用布局

denomination_layout.xml

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"

        android:layout_height="wrap_content"
        app:layout_constraintTop_toTopOf="parent">

        <TextView
            android:id="@+id/tv_denomination"

Answer 1

您可以尝试将每个放在里面并在 FrameLayout 上设置所需的尺寸

<FrameLayout
    android:id="@+id/denomination_fifty"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:layout_constraintTop_toBottomOf="@+id/tv_Cash_in_till">

    <include
        layout="@layout/denominations_layout" />
</FrameLayout>

<FrameLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:layout_constraintTop_toBottomOf="@+id/denomination_fifty">

    <include
        android:id="@+id/denomination_twenty"
        layout="@layout/denominations_layout" />
</FrameLayout>

Answer 2

要使约束起作用，您必须 add

layout_width

和

layout_height

到

<include

标签。

<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".SecondFragment">

<TextView
    android:id="@+id/tv_Cash_in_till"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginVertical="18dp"
    android:text="Cash in till"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toTopOf="parent" />

<include
    android:id="@+id/denomination_fifty"
    layout="@layout/denominations_layout"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    app:layout_constraintTop_toBottomOf="@+id/tv_Cash_in_till" />

<include
    android:id="@+id/denomination_twenty"
    layout="@layout/denominations_layout"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    app:layout_constraintTop_toBottomOf="@+id/denomination_fifty" />

<Button
    android:id="@+id/button_second"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="@string/previous"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintStart_toStartOf="parent" />
</androidx.constraintlayout.widget.ConstraintLayout>
