expandablelistview

问题 I want to have more than one expandable list within a layout. It appears that an expandable list in a custom layout must have an id of "@id/android:list". So, how could I have more than one if they would need to have the same id? Thanks... 回答1: They don't have to have the @id/android:list ID - they only have to have that ID if you are using a ListActivity or ExpandableListActivity . Just use a normal Activity and give them unique IDs. 来源： https://stackoverflow.com/questions/1209726/multiple

问题 Hey so basically I have a Sign-in/Register screen for an app and I have to make it using an ExpandableListView as shown. Based on the position of the child in a group I have inflated different views. So for positions 0 and 1, I have inflated 2 different EditText boxes. My problem is I can't get the text that is typed in both the boxes. The box allows me to type continuously but when I click the Sign-In button, the strings I get from the username and password boxes using getText are both null!

问题 I'm using an ExpandableListView to get an expandable list. I have 3 expandable "parent" lists: Price, Details, Notes. I want to be able to add unique child lists for each parent list. But the way its set up now, the same child list is being added for each parent list. How do I make it so I can add unique, separate child lists for Price, Details, and Notes?

问题 I've been attempting to work out how to add a child View to a child List in an ExpandableListActivity , but to no avail. I can get the ExpandableListView and call addFooterView() on it, but that just adds the new View to the group list. (The data comes from a Cursor ). Any suggestions gratefully received. Cheers James 回答1: Unfortunately there is no ExpandableListView.addChildFooterView() method, or even ExpandableListView.addFooterView() for that matter. The method you are calling is the

问题 I am trying to compose a list with some items expandable and some single items. I wish to have it so that when either a single item or expandable list child is clicked, I can call an intent based on the text of the item. I suppose expandable lists would work, but is there a way to set items in an expandable list so that they don't have the expandable list icon? Should I use something other than a string array? What is the best way to do this? Thanks Below is my incomplete code, I would like
