Question

我工作了10个小时，但没有理解问题出在哪里。我尝试了一切，虽然有不同的stackoverflow帖子有类似的问题，我找不到一个解决我的情况，我有一个直觉，因为这行执行时出现错误 View view = inflater.inflate（R.layout.frag1，container，false）; 调试器证实了我的意思。谢谢你的关注

这是DDMS

Answer 1

在frag1.xml中，您有一个ImageView，其中包含另一个元素：

<ImageView ...>
    <TextView ... />
</ImageView>

你做不到。 ImageView和TextView必须是对等的：

<ImageView ... />
<TextView ... />

如果您尝试将textview放在imageview的顶部，请使用允许您执行此操作的RelativeLayout parent。
