如何在 ConstraintLayout 中的图像之间的两行中对齐 TextView
How to align TextView in two lines between images in ConstraintLayout
我在 constraintlayout 中做一些设计，这让我很痛苦。我在左边有一张图片，两个垂直方向的文本在此图片的末尾对齐，我在右边有其他约束，带有图片和文本。
如果我在垂直方向的两个文本中键入一个长文本，该文本将覆盖我在视图右侧的约束。我想做的是如果这个文本很长不能覆盖这个约束，必须扩展到其他行。
这是我的代码：
<androidx.constraintlayout.widget.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<androidx.appcompat.widget.AppCompatImageView
android:id="@+id/image_slider"
android:layout_width="40dp"
android:layout_height="40dp"
android:layout_margin="8dp"
android:scaleType="centerInside"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent"
tools:src="@drawable/ic_error" />
<TextView
android:id="@+id/txt_title_animation_native_cart"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginStart="8dp"
android:textColor="@color/app_primary_medium"
android:textSize="15sp"
app:layout_constraintStart_toEndOf="@+id/image_slider"
app:layout_constraintTop_toTopOf="@+id/image_slider"

<TextView

android:layout_width="31dp"
android:layout_height="match_parent"
android:layout_marginEnd="24dp"
android:orientation="vertical"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintTop_toTopOf="parent">
<androidx.appcompat.widget.AppCompatImageView
android:id="@+id/image_undo"

android:layout_height="16dp"
android:src="@drawable/icon_loop"

app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"

首先，你不需要两个嵌套约束布局，一个就够了。
然后只需使用 endToStartoOf image_undo 设置文本并将宽度设置为 0dp 而不是 wrap_content
只需这样做：
<TextView
android:id="@+id/txt_subtitle_animation_native_cart"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginTop="4dp"
android:layout_marginEnd="4dp"
android:maxLines="2"
android:textColor="@color/app_grey_medium"
android:textSize="12sp"
app:layout_constraintStart_toStartOf="@+id/txt_title_animation_native_cart"
app:layout_constraintTop_toBottomOf="@+id/txt_title_animation_native_cart"
app:layout_constraintEnd_toStartOf="@+id/constraint_undo_button"
tools:text="Subtitle asfda sdfowei oiwue rpoweiru oiwue twoeiu t oiweu t" />
我建议您只使用一个父视图并阅读指南视图、约束链和障碍。所以一个可能的解决方案可能是下一个：
