How to keep the ExpandableListView Opened?

阅读更多关于 How to keep the ExpandableListView Opened?

I am working on the ExpandableListView I have completed the work, now only one thing that I want to do is I don't want the ListView to be DropDown on click of the Expandable List View rather I want to show it opened with all the Items displayed inside without performing any click on them. Can anyone tell me how can i do that particularly. Do this for every one of the groups to expand them: listView1.expandGroup(int groupPosition); If you want to prevent group collapse, then do this: listView1.setOnGroupClickListener(new ExpandableListView.OnGroupClickListener() { public boolean onGroupClick

问题 I'm trying to use the following code to press a button on my other application: HWND ButtonHandle; if( (wnd = FindWindow(0, "Do you want to save?")) ) { ButtonHandle = FindWindowEx(wnd, 0, "SaveButton", "&Save"); SendMessage(wnd, WM_COMMAND, MAKEWORD(GetDlgCtrlID(ButtonHandle), BN_CLICKED ), (LPARAM)ButtonHandle); } It doesn't work. I tried passing different handles to MAKEWORD and to change the WPARM and LPARAM but nothing. Any ideas on how to click a button on another application's window?
