6)在上面的代码中,我创建了两个树视图(一个直接位于活动内部,另一个位于此活动的抽屉中),每个树视图有一个块。First TreeView Block contains data started with a(a,a1,a2,…),where as second TreeView Block contains data started with b(b,b1,b2,…).The idea here is that I'm trying tochange the data of First TreeView Block and second TreeView Block at the same time.by clicking a button from inside the drawer(b_treeview_in)并从打开的列表中选择数据。上述代码在此库的0.1.0版本中正常工作(两个TreeView块的数据都已更新),但在更新到版本(0.1.1或0.1.2)后工作不正常(第一个TreeView块数据已更新,但第二个TreeView块数据未更新)。注意:在这两种情况下,如果我检查数据,我会发现它更改为从列表中选择的内容,但在第二个TreeView块的情况下,它不会更改为选择的内容。


7)如果此问题是由notifyDataChanged()引起的,那么为什么它对第一个TreeView块有效?

6)在上面的代码中,我创建了两个树视图(一个直接在活动中,另一个在该活动的抽屉中)每个街区一个。第一个TreeView块包含以a(a,a1,a2,…)开头的数据,第二个TreeView块包含以b(b,b1,b2,…)开头的数据。这里的想法是我正在努力同时更改第一个TreeView块和第二个TreeView块的数据从抽屉里点击一个按钮(B-TeReVIEWIN)从打开的列表中选择数据。上述代码在此库的0.1.0版本中正常工作(两个TreeView块的数据都已更新),但在更新到版本(0.1.1或0.1.2)后工作不正常(第一个TreeView块数据已更新,但第二个TreeView块数据未更新)。注意:在这两种情况下,如果我检查数据,我会发现它更改为从列表中选择的内容,但在第二个TreeView块中,它不会更改为选择的内容。

7)如果此问题是由notifyDataChanged()或adapter.getNode(),那么为什么它对第一个TreeView块有效?

这里是TreeView的开发者!
不幸的是,这个问题是由图书馆引起的。我上传了一个新版本,应该可以修复它。请试试看。
