3 个答案:

答案 0 :(得分：2)

android:layout_alignBottom="@+id/secondLine" // remove this

for textview1

和

android:layout_below="@id/textView1"

for textView2

原因

java.lang.IllegalStateException: Circular dependencies cannot exist in RelativeLayout

删除其中一个，它应该可以正常工作

将第TextView个secondLine的{​​{1}}与TextView相对，ID为textview1。你有循环依赖，这是不可能的，因此错误。

您需要相对于另一个放置一次视图。

答案 1 :(得分：0)

您正在为textView1分配android:layout_alignBottom="@+id/secondLine" 在第二个TextView中，您要将secondLine分配给android:layout_below="@id/textView1"

这意味着您要将一个textview分配给另一个，而第二个分配给第一个。

这是creting循环依赖。

您无法协助TextView1 <--> TextView2个关联。你只能分配单面。

删除任一行。

android:layout_alignBottom="@+id/secondLine"

或

android:layout_below="@id/textView1"

答案 2 :(得分：0)

两个TextView都指向它们中的每一个，如 android：layout_alignBottom =“@ + id / secondLine”和 android：layout_below =“@ id / textView1”所以它形式像圆形循环，因此你得到错误。从第一个textview中删除 android：layout_alignBottom =“@ + id / secondLine”
