我有一个dialogfragment,它显示的很好,但有时当我试图显示它时,我总是得到IllegalStateException
下面是logcat
java.lang.IllegalStateException: Fragment already added: SelectPlan04Dialog{fa768dc #7 }

这是调用对话框的代码
if (selectPlan04Dialog == null) {
selectPlan04Dialog = new SelectPlan04Dialog();
}
if (!selectPlan04Dialog.isVisible() && !selectPlan04Dialog.isAdded()) {
Bundle b = new Bundle();
b.putSerializable("moduleApi", module);
selectPlan04Dialog.setArguments(b);
selectPlan04Dialog.show(getCurrentActivity().getSupportFragmentManager(), "");
}

片段事务是异步的。
在执行片段事务之前,可能有两次或多次调用此代码。
!selectPlan04Dialog.isVisible() & !selectPlan04Dialog.isAdded()
条件为真,并且show()
计划稍后执行另一个片段事务。修复此问题的一些选项:
executePendingTransactions()
将异步片段事务更改为同步atmip9wb2#
在这里我的解决方案,我已经尝试点击显示对话框片段点击按钮多次和快速。
