单击按钮即可重新加载列表内容

Question

i am trying to develop this app in android that has 3-4 buttons and a list being displayed below them. each button when clicked must reload the list with new contents based on which button was clicked. each row in the list has a picture and two lines of text. could some one please suggest me how do I perform the reloading part.

Answer 1

将具有更新的元素的新适配器与listView附加在一起，它将像重新加载列表视图一样工作……

Answer 2

You could grab the list, in whatever layout it is in (ex LinearLayout) by doing a:

LinearLayout ll = (LinearLayout)getViewById(R.id.thislayout)

Remove the elements from the list as you desire using:

ll.removeView(view);

edit the view object as you want (changing the source etc) then re-add it to the LinearLayout using:

ll.addView(view);
