我需要以下一种方式管理正文下面的项目。 如果我们有很多地方,“右”文字应该与左边文字对齐。如果我们没有地方,“RIGHT”文本应该在父级的右侧,而左侧文本应该被删除。如果我们有很多地方,右边的文字不应该在右边。 感谢。

我已解决您的问题,请参阅以下代码:

    <TextView
    android:id="@+id/textView3"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:ellipsize="marquee"
    android:singleLine="true"
    android:textColor="#9b9b9b"
    android:textSize="14sp"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintEnd_toStartOf="@id/tv_status"
    app:layout_constraintHorizontal_bias="0.0"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toBottomOf="@+id/textView"
    tools:text="This text can be long too. In should not shift view at rights"/>

<TextView
    android:id="@+id/tv_status"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginEnd="16dp"
    android:paddingStart="12dp"
    android:textColor="@android:color/black"
    android:textSize="12sp"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintStart_toEndOf="@id/textView3"
    app:layout_constraintHorizontal_bias="0.0"
    tools:text="LIVE" />

更新代码:

    <TextView
    android:id="@+id/textView3"
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:ellipsize="marquee"
    android:singleLine="true"
    android:textColor="#9b9b9b"
    android:textSize="14sp"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintEnd_toStartOf="@id/tv_status"
    tools:text="This text can be long too. In should not shift view at rights" />

<TextView
    android:id="@+id/tv_status"
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:textColor="@android:color/black"
    android:textSize="12sp"
    app:layout_constraintBottom_toBottomOf="@+id/textView3"
    app:layout_constraintEnd_toEndOf="parent"

You can try it by nesting another layout that has flexible children 
placement like the RelativeLayout
`<?xml version="1.0" encoding="utf-8"?>
