Android - ConstraintLayout - 大文本的椭圆末尾

Question

我需要一些有关 Android 布局的帮助。我有以下代码:

<?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"

    android:gravity="center_horizontal"

    app:layout_constraintLeft_toLeftOf="parent"
    app:layout_constraintRight_toLeftOf="@id/guideline"
    tools:text="TOTAL" />
</android.support.constraint.ConstraintLayout>

输出是:

我的问题是:如果主值 (17.40) 太大，该值应该“省略”以结束，但它会覆盖“Activity ”文本。

大文本的输入是:

我需要这样的东西来获得大值(value):

PS:单位和标志应该始终显示在主值的末尾。

你能帮我提点建议吗？我尝试了很多想法，但没有找到解决方案。

Answer 1

1. 将子布局宽度设置为 0dp

android:layout_width="0dp"

1. 设置 Right_toRightOf 和Left_toRightOf

app:layout_constraintLeft_toRightOf="@+id/listingImageView" app:layout_constraintRight_toRightOf="parent" app:layout_constraintTop_toTopOf="parent"
