基本上，错误是针对以下地方:
View view = inflater.inflate(R.layout.input, container,false);
这只发生在模拟器中，不会发生在手机中。这里有什么问题？

检查您的 drawable/background_main 即根布局的背景图像 - 解码位图时 VM 内存不足。缩小图片尺寸。

我早就知道Ruby中的“常量”(即大写的变量名)不是真正常量。与其他编程语言一样，对对象的引用是唯一存储在变量/常量中的东西。(侧边栏:Ruby确实具有“卡住”引用对象不被修改的功能，据我所知，许多其他语言都没有提供这种功能。)所以这是我的问题:当您将一个值重新分配给常量时，您会收到如下警告:>>FOO='bar'=>"bar">>FOO='baz'(irb):2:warning:alreadyinitializedconstantFOO=>"baz"有没有办法强制Ruby抛出异常而不是打印警告？很难弄清楚为什么有时会发生重新分配。 最佳答案
