我的布局上有循环依赖项错误，我试图找到任何循环依赖但却无法找到它，任何看到的人？

java.lang.IllegalStateException：RelativeLayout

中不存在循环依赖关系

Answer 1

错误在于以下组件

<Button
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Natureza"
    android:id="@+id/btnNatureza"
    android:onClick="btnPassearonClick"
    android:layout_above="@+id/imageView2"
    android:layout_marginBottom="10dp"
    android:layout_toLeftOf="@+id/imageView11"
    android:layout_toStartOf="@+id/imageView11" />

<ImageView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:id="@+id/imageView11"
    android:layout_toEndOf="@+id/btnNatureza"
    android:src="@drawable/passear"
    android:layout_alignBottom="@+id/btnNatureza"
    android:layout_toRightOf="@+id/btnNatureza" />

您指定btnNatureza必须位于imageView11的右侧，但是您告诉imageView11它必须位于btnNatureza的左侧。这是一个循环依赖，因为任何一个视图都没有引用的起始点，它们相互依赖来确定它们的位置。要解决此问题，您必须从android:layout_toLeftOf="@+id/imageView11"移除Button或从android:layout_toRightOf="@+id/btnNatureza"移除ImageView

Answer 2

btnNatureza是指imageView2，其引用的imageView11引用btnNatureza

一般来说，你不能说A位于B的底部而B位于A之上。只需保留一个。

<Button
    android:id="@+id/btnNatureza"
    android:layout_above="@+id/imageView2"
    android:layout_toLeftOf="@+id/imageView11"
    android:layout_toStartOf="@+id/imageView11" />

<ImageView
    android:id="@+id/imageView11"
    android:layout_toEndOf="@+id/btnNatureza"
    android:layout_alignBottom="@+id/btnNatureza"
    android:layout_toRightOf="@+id/btnNatureza" />

<ImageView
    android:id="@+id/imageView2"
    android:layout_toEndOf="@+id/imageView11"
    android:layout_toRightOf="@+id/imageView11" />

Answer 3

这两个视图相互引用

<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Natureza"
android:id="@+id/btnNatureza"
android:onClick="btnPassearonClick"
android:layout_above="@+id/imageView2"
android:layout_marginBottom="10dp"
android:layout_toLeftOf="@+id/imageView11"
android:layout_toStartOf="@+id/imageView11" />

<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/imageView11"
android:layout_toEndOf="@+id/btnNatureza"
android:src="@drawable/passear"
android:layout_alignBottom="@+id/btnNatureza"
android:layout_toRightOf="@+id/btnNatureza" />

循环布局依赖项
