android - 如何使用 onFinishInflate 知道 View 何时膨胀

Question

我想知道我的 TabActivity 何时膨胀，所以我尝试了这段代码

 @Override
 protected void onFinishInflate() {
     super.onFinishInflate();
 }

我收到错误:必须覆盖或实现父类(super class)型方法
我不明白为什么这在 TabActivity 中不起作用。
谁能解释一下？

安Activity不是 View . Activity 中没有onFinishInflate 方法。在 setContentView 中使用的 View 膨胀后，您需要做什么？

我认为在单独的 Activity 中尝试混淆 View 是非常糟糕的做法。查看这些链接以了解在选项卡之间共享数据的替代方法

• Sharing data between tabs
• Passing ArrayList<String> between tabs
