我正在制作一个Android应用程序,其中某些布局无法正确缩放.cardviews相互冲突,我知道这是由于硬编码像素引起的,但是如果我不这样做,如何实现这种类型的输出
这是我的XML代码:

如果您不熟悉android,建议您从更简单的布局开始,因为ConstraintLayout有点棘手。它试图同时做所有事情,这使得使用起来很复杂。请尝试使用LinearLayout。我试图编辑您的布局,这就是我得到的。

在Android中,开发Android应用程序时需要考虑不同屏幕尺寸的数量。
不同的手机具有不同的屏幕尺寸,在您的布局中,您使用的是固定尺寸的视图(例如,固定尺寸为50dp
),结果是看起来效果不错一个屏幕(您的android studio预览屏幕)在另一屏幕(您的实际手机)上看起来效果不佳。
为解决您的问题,我建议将ConstraintLayout与guidelines和Chains结合使用以支持不同的屏幕尺寸。
以下是与您想要的布局相同的示例:
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout

app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<Button

android:layout_width="0dp"
android:layout_height="0dp"
android:text="2"

app:layout_constraintHorizontal_bias="0.5"

app:layout_constraintTop_toTopOf="@+id/button8" />
<Button
android:id="@+id/button9"

<Button

android:layout_height="0dp"
android:text="4"
app:layout_constraintBottom_toBottomOf="@+id/button6"
app:layout_constraintEnd_toStartOf="@+id/button3"
app:layout_constraintStart_toEndOf="@+id/button6"
app:layout_constraintTop_toTopOf="@+id/button6" />
<Button
android:id="@+id/button6"
android:layout_width="0dp"
android:layout_height="0dp"
android:text="3"
app:layout_constraintBottom_toTopOf="@+id/button7"
app:layout_constraintEnd_toStartOf="@+id/button5"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="@+id/button" />
<Button
android:id="@+id/button7"
android:layout_width="0dp"
android:layout_height="0dp"
android:layout_marginStart="8dp"
android:layout_marginLeft="8dp"
android:layout_marginEnd="8dp"
android:layout_marginRight="8dp"
android:text="6"
app:layout_constraintBottom_toTopOf="@+id/button8"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="@+id/button6" />
<Button
android:id="@+id/button8"
android:layout_width="0dp"
android:layout_height="0dp"
android:text="7"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toStartOf="@+id/button9"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="@+id/button7" />
</android.support.constraint.ConstraintLayout>
它看起来像这样:
