有人能帮我吗?:我真的很感谢你花时间和帮助我解决我的错误。提前谢谢 您的布局XML中引用了一个自定义视图,而自定义视图没有所需的
public
构造函数,该构造函数接受上下文、AttributeSet
参数。如果您在本文中使用Kotlin,请使用@JvmOverloads
注释您的构造函数
文件:
例如:
class MyView@JVM重载构造函数(context:context,attrs:AttributeSet?=null,defStyle:Int=0):LinearLayout(context,attrs,defStyle)
Hi laalto:)我不明白你的意思,我是android开发新手,对不起:/但我在你的代码中包含了我的xml文件:,Tutorial3View
没有布局膨胀所需的2-arg构造函数Tutorial3View(Context,AttributeSet)
。请记住,这些构造函数必须是公共的。@David您让我在public
上。多谢!我的应用程序仅在发布版本中崩溃。罪犯失踪了。
