Android：如何在ListActivity中设置setSelection（）

Question

I have a Class which extends ListActivity, and is called by Activity_1.

ListActivity contains the listview with CheckedTextView.

When i select a row in listview, it should show a CheckedTextView and pass the data to Activity_1 and should remember the selected row.

The selected CheckedTextView should be shown when Activity_1 calls ListActivity again ?

Answer 1

getListView().setSelection(int);

再次调用时，您始终可以将记住的项目传递回ListActivity。
