问题描述
我有一个带有 3 个文本视图的水平 LinearLayout,宽度设置为 wrap_content。我希望它们都是包装内容,但其中一个可能会变得太长。这导致其他两个文本视图越界。如何使长文本视图仅将内容换行到 LinearLayout 的所有子项仍然存在的范围内(在父 LinearLayout 的宽度边界内(设置为 match_parent))?
代码示例:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="32dp"
android:orientation="horizontal"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintBottom_toBottomOf="parent">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="This is a very very very very very very very very very long text"
android:ellipsize="end"
android:maxLines="1"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="This is another text"
android:maxLines="1"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="One final text"
android:ellipsize="end"
android:maxLines="1"/>
</LinearLayout>
这是我得到的: undesired
这更多是我想要的: desired
注意:android:layout_weight 对我不起作用,因为我仍然希望文本视图为较小的文本包装内容。
解决方法
将父级 (LinearLayout) 的宽度设置为 wrap_content。但是,如果第一个文本视图的文本超出第二个文本视图的开头,这将导致第二个文本视图位于第一个文本视图之上。
我看到的最佳选择是为所有文本视图指定 layout_width,然后为每个文本视图设置最大文本长度。
,您可以为每个 android:maxWidth
设置 android:layout_width="wrap_content"
和 TextView
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="32dp"
android:orientation="horizontal"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintBottom_toBottomOf="parent">
<TextView
android:layout_width="wrap_content"
android:maxWidth="150dp"
android:layout_height="wrap_content"
android:text="This is a very very very very very very very very very long text"
android:ellipsize="end"
android:maxLines="1"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:maxWidth="150dp"
android:text="This is another text"
android:maxLines="1"/>
<TextView
android:layout_width="wrap_content"
android:maxWidth="150dp"
android:layout_height="wrap_content"
android:text="One final text"
android:ellipsize="end"
android:maxLines="1"/>
</LinearLayout>
,
在您的 LinearLayout 中更改布局权重:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="32dp"
android:orientation="horizontal"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintBottom_toBottomOf="parent">
<TextView
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:background="@color/teal_200"
android:text="This is a very very very very very very very very very long text"
android:ellipsize="end"
android:maxLines="1"/>
<TextView
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:background="@color/teal_700"
android:text="This is another text"
android:maxLines="1"/>
<TextView
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:background="@color/purple_500"
android:text="One final text"
android:ellipsize="end"
android:maxLines="1"/>
</LinearLayout>
