應用程序崩潰：IllegalStateException：在RelativeLayout中不存在循環依賴關係

我試圖按照書中的教程進行操作。我在一本500頁的書中約有200頁，一切都運行良好，直到有一天，我收到一條錯誤消息，說「不幸的是」該應用程序「已停止」。我不想重新開始，並嘗試在這個論壇上的解決方案，看看我是否可以得到一個答案，如去Windows - 首選項 - Android的 - DDMS - 滴答ADHOST，重新啓動Eclipse和關閉ADT等，但沒有似乎解決了這個問題。從我收集的信息來看，這個錯誤對於每個應用程序都是獨一無二的，我應該在論壇上發佈來自logcat的日誌，以便其他人可以比我更聰明地分析它。應用程序崩潰：IllegalStateException：在RelativeLayout中不存在循環依賴關係

以下是從logcat的結果：

誰能幫助我嗎？

這裏是我的AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>

    </application> 

</manifest>

我想通了，它涉及XML。爲此，循環依賴錯誤出現的XML數據如下：

'java.lang.IllegalStateException：循環依賴不能存在於RelativeLayout'中 - 請發佈您的佈局XML請。 – laalto

查找兩個或多個相互依賴的佈局視圖。你不能說「一個是對的b」和「b是留給一個」。這是循環依賴。 –

上面顯示的佈局。 – Simon

我假設你試圖有兩列，文本|數據。爲了模式的原因，我將dataView1代碼移動到textView1下面，並將其放置到RightOf = textView1並取出「alignLeft」和「above」。

<TextView 
android:id="@+id/dataView1" 
android:layout_width="wrap_content" 
android:layout_height="wrap_content" 
android:layout_toRightOf="@+id/textView1" 
android:text="string/planet_name_label" 
android:textColor="#FFFF99" />

我試圖找到其中的循環依賴存在....我STOPP因爲你的代碼讓我頭痛。也許你可以從TextView1，TextView2，TextView3等和DataView1，Dataview2，Dataview3等改變你的XML ID名稱到一些有意義的東西？

LOL。多數民衆贊成在這本書是如何完成的:)我發現了循環例外。它在dataView1的最後一個文本框中。它不正確地引用textView8和dataView7導致循環依賴。 – Simon
