Question

我正在开发一个应用，希望在容器中依次显示几个片段（框架布局）。我希望我的片段适合框架布局，而其部分不会超出屏幕。

我想要这个：

但是得到这个：

这是我的代码段：

<android.support.constraint.ConstraintLayout
    android:id="@+id/relativeLayout"
    android:layout_width="0dp"
    android:layout_height="0dp"
    android:layout_marginStart="24dp"
    android:layout_marginEnd="24dp"
    android:layout_marginBottom="24dp"
    android:background="@drawable/grey_border_circular_rect"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintHorizontal_bias="1.0"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toTopOf="@+id/guideline3"
    app:layout_constraintVertical_bias="0.0">


     <FrameLayout
        android:id="@+id/fragment_holder"
        android:layout_width="0dp"
        android:layout_height="0dp"
        android:layout_marginBottom="32dp"
        app:layout_constraintBottom_toTopOf="@+id/elipse1"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent">

    </FrameLayout>

    <android.support.constraint.Guideline
        android:id="@+id/guideline4"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:orientation="horizontal"
        app:layout_constraintGuide_end="32dp" />


    <ImageView
        android:id="@+id/elipse1"
        android:layout_width="14dp"
        android:layout_height="14dp"
        app:layout_constraintEnd_toStartOf="@+id/elipse2"
        app:layout_constraintHorizontal_bias="0.5"
        app:layout_constraintHorizontal_chainStyle="packed"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toBottomOf="@+id/guideline4"
        app:srcCompat="@drawable/ic_elipse_filled"
        tools:layout_editor_absoluteY="568dp" />

    <ImageView
        android:id="@+id/elipse2"
        android:layout_width="14dp"
        android:layout_height="14dp"
        android:layout_marginStart="8dp"
        app:layout_constraintBottom_toBottomOf="@+id/elipse1"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintHorizontal_bias="0.5"
        app:layout_constraintStart_toEndOf="@+id/elipse1"
        app:srcCompat="@drawable/ic_elipse_blank" />
</android.support.constraint.ConstraintLayout>

我无法共享完整的xml代码，因为我对代码有一些限制。但是Root布局也是ConstraintLayout。

fragment.xml

那么我有什么可能的方法可以使片段适合任何屏幕尺寸，并且所有片段都可以在帧布局内看到。

Answer 1

以下代码将帮助您处理 fragment.xml 文件。您没有提供更多的值文件，包括颜色代码，字符串文件等。因此，以下是文件中的一些更改，例如可绘制和与值相关的数据。
