Answer 1

您不应该在以下 View 之间添加循环依赖关系:

从您的代码中删除一行-

remove - `android:layout_above="@+id/textView4"`

从下面看-

<TextView
android:id="@+id/y_axis"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_above="@+id/textView4"
android:layout_alignStart="@+id/x_axis"
android:layout_alignParentEnd="true"
android:background="#0f0"
android:textAppearance="?android:attr/textAppearanceMedium"
android:textColor="#f00" />
