如何在xml文件中創建ToggleButton？

我創建了一個新的xml文件「test.xml」來測試ToggleButton，所以如果我在圖形佈局中拖動一個ToggleButton。佈局變得有點暗，但我無法在圖形佈局中看到拖動的ToggleButton。在text.xml中我可以看到它的代碼！如何在xml文件中創建ToggleButton？

拖動後，顯示此錯誤：

Exception raised during rendering: -1 
Exception details are logged in Window > Show View > Error Log

在錯誤日誌文件中的錯誤：

java.lang.ArrayIndexOutOfBoundsException: -1

你看錯誤日誌中的錯誤嗎？ –

我將其添加到問題中。對我來說沒有什麼特別的錯誤。 –

有同樣的問題 - 嘗試使用CheckBox或support-v7開關，至少在找到合適的解決方案之前。 –

我的解決方案是在圖形佈局中切換API。我從API 21切換到API 19.

你的答案適合我。在我的情況下，我設置了一個自定義形狀drawable.xml文件作爲按鈕的背景。它使用普通的.png編譯按鈕背景，但是當我嘗試使用shape.xml時，它失敗了。我的堆棧跟蹤的前幾行：'java.lang.ArrayIndexOutOfBoundsException：-1 \t at android.view.ShadowPainter.createDropShadow（ShadowPainter.java:116）' – GraSim

只是好奇這是爲什麼，並且有我的自定義組件我需要做的是讓這個錯誤消失API21？ – JPM

-1

它對我有用。另外android:text不是ToggleButton的有效屬性。使用android:textOn和android:textOff來設置按鈕狀態的文本。
