嗨,我正在尝试查看时间表。 如果用户原样设置在显示器24H中,则开放时间的格式会更改。还有一天,商店关门了。字符串Closed是动态的,它每天都可能来自VM.days.get(X).time
我想在小时的左侧将关闭位置对齐。
这是我的ConstraintLayout

我尝试将所有timeUI宽度设置为0dp,并从障碍开始,进入父级。但是,如果所有时间UI都有这些约束,它们都会消失
答案 0 :(得分:2)
您也可以使用Barrier。
使用Barrier
,您可以将开始<->障碍物<->结束对齐,然后在障碍物中将要与障碍物对齐的视图的所有ID放入,然后设置Barrier
指向所有这些视图中的start
的方向:
<androidx.constraintlayout.widget.Barrier
android:id="@+id/barrier"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:barrierDirection="end"
app:constraint_referenced_ids="textView1,textView2,..." />
答案 1 :(得分:1)
有很多解决方案:
1-使用带有2个垂直LinearLayouts(位置开始和结束)的FrameLayout
2-如果您坚持使用约束布局,则可以尝试为文本视图设置宽度(特别是在右侧)
3-我真的不确定会发生什么,但是您可以尝试使闭合的一个宽度match_parent而不是wrap_content
答案 2 :(得分:1)
从“已关闭”视图中删除了右/结束约束。这将使它左对齐:
<TextView
android:id="@+id/second_time"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@{VM.days.get(1).time}"
android:textColor="@{VM.days.get(1).highlight ? @color/red : @color/gray}"
app:isBold="@{VM.days.get(1).isBold}"
app:layout_constraintBottom_toBottomOf="@id/second_day"
app:layout_constraintStart_toStartOf="@id/barrier"
app:layout_constraintTop_toTopOf="@id/second_day"
tools:text="Closed" />
还要在左/右和开始/结束约束之间进行选择。两者都是多余的。此外,在引用视图时,无需在名称中包含“ +”号。
