java.lang.IllegalArgumentException:找不到id 0x7f0c0098的视图

我有一份很好的NBA球队名单并正确填写了球队名单,但是当我点击列表中的项目时,它应该给另一个片段充气,以显示所选球队的描述,但是当我做的时候点击无法找到fragment_descriptions id。

我为团队使用了两个List Fragment,另一个用于Players,为此我使用ViewPager和Placeholder Fragment(由Android Studio自动生成),我认为这是因为fragment_description的布局何时不会膨胀:/

谢谢:)我整天都在犯错:(

答案 0 :(得分:0)

我快速浏览了github上的项目,我认为你应该用这一行替换这一行

transaction.replace(R.id.fragment_descriptions, newDescriptionFragment);


< br /> transaction.replace(R.id.fragment_team_movil, newDescriptionFragment);

在您的 MainActivity.java
