片段没有完全膨胀

问题描述 投票：1回答：1

我创建了一个包含三个选项卡的Activity。单击选项卡1时，它会打开一个包含两个按钮的片段（TaskFragment），每个按钮都有一个关联的文本。

当我点击“创建评估报告”按钮时，它会正确地膨胀另一个片段（AppraisalReportFragment）两个文本行（现在取代前两个）和页面标题（评估报告），但两个初始按钮保持不变。

我试图让最初的Fragment上的所有东西都被改成一个全新的Fragment，它有自己的按钮和文本），但是现在只发生了一些变化。

当您为片段充气时，在活动中提交FragmentManager的事务后，您应该将gone的可见性设置为上一个布局中的按钮

您可以这样做，然后在返回时再将它们更改为visible

b1.setVisibility(View.GONE);
b2.setVisibility(View.GONE);

根据您的代码更改按钮的名称
