如何在 xml 文件中创建 ToggleButton？

Question

我创建了一个新的 xml 文件“test.xml”来测试 ToggleButton，所以如果我在图形布局中拖动一个 ToggleButton。布局变得有点暗，但我在图形布局中看不到拖动的 ToggleButton。在 text.xml 中我可以看到它的代码！

拖动后显示此错误：

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

errorLog文件中的错误：

java.lang.ArrayIndexOutOfBoundsException: -1

Answer 1

我的解决方案是在图形布局中切换 API。我从 API 21 切换到 API 19。

Answer 2

它对我有用.. 另外android:text 不是 ToggleButton 的有效属性。使用android:textOn 和android:textOff 设置按钮状态的文本。
