如您所见,我在RecyclerView
换行中遇到了文本,但其中一些不在屏幕上(突出显示的部分是匹配的部分)
我将包含RecyclerView
的fragment_news装入activity_main的FrameLayout
中,news_list_item定义了RecyclerView
中的项目。我想我在某个地方弄乱了一些物业,但不确定哪一个。
这是我正在使用的xml代码:
activity_main.xml

使用
app:layout_constrainedWidth="true"
,宽度设置为wrap_content
在您的TextView中。
还要在TextView中将宽度设置为0dp
app:layout_constraintWidth_default="wrap"
,宽度设置为0dp
