Answer 1

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

爲textview1

和

android:layout_below="@id/textView1" 

爲textView2

導致

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

刪除其中的一個，它應該工作

將第二TextView ID爲secondLine相對於TextView id爲textview1。你有循環依賴這是不可能的，因此也是錯誤。

您需要放置一次相對於另一個視圖。

Answer 2

您分配一個textView1到android:layout_alignBottom="@+id/secondLine" 和第二TextView中要指定secondLine到android:layout_below="@id/textView1"

它意味着你分配一個TextView的另一個和第二到第一位。

這是creting循環依賴關係。

您無法分配TextView1 <--> TextView2連接。你只能分配單面。

刪除任一行。

android:layout_alignBottom="@+id/secondLine" 

或

android:layout_below="@id/textView1" 

Answer 3

兩個TextViews都指向它們中的每一樣機器人：layout_alignBottom = 「@ + ID /二線」和機器人：layout_below = 「@ ID/textView1」所以它就像循環一樣，因此你會得到錯誤。從第一個文本視圖刪除此android：layout_alignBottom =「@ + id/secondLine」
