android - android中每个元素的ConstraintLayout等间距

问题描述

我有下面的等距圆的代码和用于连接的中间进度条，我没有从下面的代码中为每个圆获得相等的空间，请任何人帮我解决这个问题。我需要显示等距的圆，没有指定边距，然后还有开始和结束空间

解决方案

编辑您的布局，如下所示：

<androidx.constraintlayout.widget.ConstraintLayout 
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toBottomOf="@+id/spb_followup">

<ProgressBar
    android:id="@+id/progressBar2"
    style="?android:attr/progressBarStyleHorizontal"
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:progress="30"
    android:progressTint="@color/red"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintEnd_toEndOf="@+id/imageView7"
    app:layout_constraintStart_toStartOf="@+id/imageView"
    app:layout_constraintTop_toTopOf="parent" />


<TextView
    android:id="@+id/imageView"
    android:layout_width="40dp"
    android:layout_height="40dp"
    android:background="@drawable/circular_bg"
    android:gravity="center_vertical|center_horizontal"
    android:text="Aug"
    android:textColor="#fff"
    android:textSize="14sp"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintEnd_toStartOf="@+id/imageView2"
    app:layout_constraintHorizontal_bias="0.5"
    app:layout_constraintHorizontal_chainStyle="spread"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toTopOf="parent" />

<TextView
    android:id="@+id/imageView2"
    android:layout_width="40dp"
    android:layout_height="40dp"
    android:background="@drawable/circular_bg"
    android:gravity="center_vertical|center_horizontal"
    android:text="Aug"
    android:textColor="#fff"
    android:textSize="14sp"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintEnd_toStartOf="@+id/imageView3"
    app:layout_constraintHorizontal_bias="0.5"
    app:layout_constraintHorizontal_chainStyle="spread"
    app:layout_constraintStart_toEndOf="@+id/imageView"

    android:textColor="#fff"
    android:textSize="14sp"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintEnd_toStartOf="@+id/imageView4"
    app:layout_constraintHorizontal_bias="0.5"
    app:layout_constraintHorizontal_chainStyle="spread"
    app:layout_constraintStart_toEndOf="@+id/imageView2"
    app:layout_constraintTop_toTopOf="parent" />

<TextView
    android:id="@+id/imageView4"
    android:layout_width="40dp"
    android:layout_height="40dp"
    android:background="@drawable/circular_bg"
    android:gravity="center_vertical|center_horizontal"
    android:text="Aug"
    android:textColor="#fff"
    android:textSize="14sp"

    app:layout_constraintEnd_toStartOf="@+id/imageView5"
    app:layout_constraintHorizontal_bias="0.5"
    app:layout_constraintHorizontal_chainStyle="spread"
    app:layout_constraintStart_toEndOf="@+id/imageView3"
    app:layout_constraintTop_toTopOf="parent" />


<TextView
    android:id="@+id/imageView5"
    android:layout_width="40dp"
    android:layout_height="40dp"
    android:background="@drawable/circular_bg"
    android:gravity="center_vertical|center_horizontal"
    android:text="Aug"
    android:textColor="#fff"
    android:textSize="14sp"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintEnd_toStartOf="@+id/imageView6"
    app:layout_constraintHorizontal_bias="0.5"
    app:layout_constraintHorizontal_chainStyle="spread"
    app:layout_constraintStart_toEndOf="@+id/imageView4"
    app:layout_constraintTop_toTopOf="parent" />


<TextView
    android:id="@+id/imageView6"
    android:layout_width="40dp"
    android:layout_height="40dp"
    android:background="@drawable/circular_bg"
    android:gravity="center_vertical|center_horizontal"
    android:text="Aug"
    android:textColor="#fff"
    android:textSize="14sp"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintEnd_toStartOf="@+id/imageView7"
    app:layout_constraintHorizontal_bias="0.5"
    app:layout_constraintHorizontal_chainStyle="spread"
    app:layout_constraintStart_toEndOf="@+id/imageView5"
    app:layout_constraintTop_toTopOf="parent" />

<TextView
    android:id="@+id/imageView7"
    android:layout_width="40dp"
    android:layout_height="40dp"
    android:background="@drawable/circular_bg"
    android:gravity="center_vertical|center_horizontal"
    android:text="Aug"
    android:textColor="#fff"
    android:textSize="14sp"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintHorizontal_bias="0.5"
    app:layout_constraintHorizontal_chainStyle="spread"
    app:layout_constraintStart_toEndOf="@+id/imageView6"
    app:layout_constraintTop_toTopOf="parent" />

</androidx.constraintlayout.widget.ConstraintLayout>

我纠正了您的布局中的一些问题。一个是删除您在视图之间创建的错误边界，因此某些视图有超过 4 个边界，这非常令人困惑。我还添加了以下两个属性：

app:layout_constraintHorizontal_bias="0.5"
app:layout_constraintHorizontal_chainStyle="spread"

它们帮助视图在布局宽度上以相等的距离分布。
