Расположение сетки и CardView не отображаются на старом Android устройстве

0 голосов
/ 14 января 2020

Я ищу решение. Grid Layout с использованием cardView прекрасно отображается на последних устройствах, но более старые устройства, такие как Lollipop и некоторые другие версии устройства Android, не отображают Grid Layout и CardView. Пожалуйста, дайте мне решение, как будто я могу построить свой проект. Спасибо

вот мой код макета

Когда вы используете макет ограничения, не делайте их жестким кодом 

 <?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"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <ScrollView
        android:layout_width="0dp"
        android:layout_height="0dp"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent">

        <androidx.constraintlayout.widget.ConstraintLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:orientation="vertical" >

        </androidx.constraintlayout.widget.ConstraintLayout>
    </ScrollView>
</androidx.constraintlayout.widget.ConstraintLayout>

и используйте представление прокрутки внутри макета ограничения, чтобы обрабатывать представление для нижнего конечного устройства, поскольку размер экрана слишком мал.
