android-layout - Android Java - 以百分比宽度并排制作两个容器

Question

我在 android 页面中有这种情况：

    android:layout_height="match_parent"

    <RelativeLayout

        app:layout_constraintWidth_default="percent"
        app:layout_constraintWidth_percent="90" >

        <RelativeLayout         
            android:layout_width="fill_parent"
            android:layout_height="wrap_content">

            <TextView

    <RelativeLayout
        android:id="@+id/lbltvSecondContainer"
        android:layout_width="0dp"
        android:layout_height="match_parent"
        android:layout_weight="1"
        app:layout_constraintWidth_default="percent"
        app:layout_constraintWidth_percent="10">

    </RelativeLayout>
</LinearLayout>

而且我正在尝试并排放置两个容器，lbltvFirstContainer并且lbltvSecondContainer，我将在其中按百分比设置宽度，因此在第二个容器中我可以只放一个“>”，就像一个按钮一样转到另一个页面，所以在搜索后我找到了可以使用的地方那些app:layout_constraintWidth_default="percent"和app:layout_constraintWidth_percent="10"但看起来不起作用....你有一个方向来制作这两个具有百分比宽度的主要容器吗？提前致谢！

所以我重新检查了我在 XML 中输入的内容，看起来还不错，但也许我忘记或弄错了什么？

谢谢！干杯!

您好 @Cheticamp ，按照您的建议，我从头开始创建一个 ConstraintLayout ，其中包含两个按百分比标注的准则，如下所示：

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.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">


    <androidx.constraintlayout.widget.Guideline
        android:id="@+id/test_left_guideline"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:orientation="vertical"
        app:layout_constraintGuide_percent="0.50" />

    <androidx.constraintlayout.widget.Guideline
        android:id="@+id/test_right_guideline"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:orientation="vertical"
        app:layout_constraintGuide_percent="0.20"
        app:layout_constraintLeft_toEndOf="@id/test_left_guideline" />


</androidx.constraintlayout.widget.ConstraintLayout>

所以它应该在设计中并排看到这两个指南，因为我app:layout_constraintLeft_toEndOf="@id/test_left_guideline"在我可以按照这些指南将两个 RelativeLayouts 作为容器放置之后，但看起来这两个指南都从父窗口的左侧开始......我应该哪个属性设置并排制定这两个准则？提前致谢！干杯
