问题 Suppose that I want to customize the indentation rules of the foton document editor, where and how can I do that? I'll elaborate. The foton editor lays out document like this: (which to my flavor is completely annoying) { "_id": "1326017821636", "_rev": "2-51ab614953437181a24f1c073fbc6201", "doc_type": 0, "step": 2, "data": { "map1": { "attr1": 73031, "attr2": "strval" }, "map2": { "att1": 52001, "att2": "strval" }, "mapmap": { "map": { "id11": { "id": "id11", "attr": "attr", "attr2": 2222 },

问题 I'm building a ListView with either TextView s or ImageView s based on whether or not the item is a text item or has an image associated with it. I used Customizing list shown from SimpleCursorAdapter using VewBinder and it worked great, up to a point.
