Question

我希望有4个图像占据父的宽度，图像应该将总宽度除以4并有一些偏移量。这就是它的样子：

现在我想在它们下面放置四个文本标签。每个ImageView下面都应该有一个文本标签。这就是问题所在：当我尝试将TextView居中时，4个图像中的1个随机增长。我无法将图像设置为具有相同的宽度/高度。

这应该是这样的：

如何将TextView置于ImageViews下方并居中？这是XML：

对于上图所示的结果，最简单的方法是这样做，

<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"

    app:layout_constraintLeft_toLeftOf="parent"
    app:layout_constraintRight_toLeftOf="@+id/frame_2"
    app:layout_constraintTop_toTopOf="parent">

    <ImageView

您可以像对图像视图一样链接<?xml version="1.0" encoding="utf-8"?> <android.support.constraint.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"> <ImageView android:id="@+id/iv1" android:layout_width="0dp" android:layout_height="0dp" android:layout_marginEnd="8dp" android:layout_marginStart="8dp" android:layout_marginTop="8dp" android:scaleType="centerCrop" android:src="@drawable/ic_launcher_background" app:layout_constraintDimensionRatio="1" app:layout_constraintEnd_toStartOf="@+id/iv2" app:layout_constraintHorizontal_chainStyle="spread_inside" app:layout_constraintStart_toStartOf="parent" app:layout_constraintTop_toTopOf="parent" /> <ImageView android:id="@+id/iv2" android:layout_width="0dp" android:layout_height="0dp" android:layout_marginEnd="8dp" android:layout_marginStart="8dp" android:scaleType="centerCrop" android:src="@drawable/ic_launcher_background" app:layout_constraintDimensionRatio="1" app:layout_constraintEnd_toStartOf="@+id/iv3" app:layout_constraintStart_toEndOf="@+id/iv1" app:layout_constraintTop_toTopOf="@+id/iv1" /> <ImageView android:id="@+id/iv3" android:layout_width="0dp" android:layout_height="0dp" android:scaleType="centerCrop" android:src="@drawable/ic_launcher_background" app:layout_constraintDimensionRatio="1" app:layout_constraintEnd_toStartOf="@+id/iv4" app:layout_constraintStart_toEndOf="@+id/iv2" app:layout_constraintTop_toTopOf="@+id/iv1" /> <ImageView android:id="@+id/iv4" android:layout_width="0dp" android:layout_height="0dp" android:layout_marginEnd="8dp" android:scaleType="centerCrop" android:src="@drawable/ic_launcher_background" app:layout_constraintDimensionRatio="1" app:layout_constraintEnd_toEndOf="parent" app:layout_constraintStart_toEndOf="@+id/iv3" app:layout_constraintTop_toTopOf="@+id/iv1" /> <TextView android:id="@+id/tv1" android:layout_width="0dp" android:layout_height="wrap_content" android:layout_marginEnd="8dp" android:layout_marginStart="8dp" android:layout_marginTop="8dp" android:gravity="center" android:text="Textview" android:textSize="20sp" app:layout_constraintEnd_toStartOf="@+id/tv2" app:layout_constraintHorizontal_chainStyle="spread_inside" app:layout_constraintStart_toStartOf="parent" app:layout_constraintTop_toBottomOf="@+id/iv1" /> <TextView android:id="@+id/tv2" android:layout_width="0dp" android:layout_height="wrap_content" android:layout_marginEnd="8dp" android:layout_marginStart="8dp" android:gravity="center" android:text="Textview" android:textSize="20sp" app:layout_constraintEnd_toStartOf="@+id/tv3" app:layout_constraintStart_toEndOf="@+id/tv1" app:layout_constraintTop_toTopOf="@+id/tv1" /> <TextView android:id="@+id/tv3" android:layout_width="0dp" android:layout_height="wrap_content" android:layout_marginEnd="8dp" android:layout_marginStart="8dp" android:gravity="center" android:text="Textview" android:textSize="20sp" app:layout_constraintEnd_toStartOf="@+id/tv4" app:layout_constraintStart_toEndOf="@+id/tv2" app:layout_constraintTop_toTopOf="@+id/tv1" /> <TextView android:id="@+id/tv4" android:layout_width="0dp" android:layout_height="wrap_content" android:layout_marginEnd="8dp" android:layout_marginStart="8dp" android:gravity="center" android:text="Textview" android:textSize="20sp" app:layout_constraintEnd_toEndOf="parent" app:layout_constraintStart_toEndOf="@+id/tv3" app:layout_constraintTop_toTopOf="@+id/tv1" /> </android.support.constraint.ConstraintLayout>小部件。
