How to resize a ListView when new rows are added?

由 你。 提交于 2019-12-08 07:51:00

问题 How can I create multiple list views within a single activity? Each ListView should have a separated header which allows expanding or collapsing its list, and scrolling on any ListView should scroll the entire activity (NOT one scroll for first ListView and another for second ListView ONLY one scroll for BOTH ListView ...) listviews dynamically fills...
