ListView 滚动到所选项目

Question

I have a ListView with an edit text and a button below it. When I click on a listView item the keyboard appears and push up the edit text and the button. I want the list to scroll to the selected item. Any idea? Thanks

Answer 1

您可以使用 ListView 的setSelection(int position)方法滚动到一行。

Answer 2

您可以使用 ListView 的smoothScrollToPosition(int position)滚动到列表中的特定位置。

Answer 3

For a direct scroll:

getListView().setSelection(11);

For a smooth scroll:

getListView().smoothScrollToPosition(11);

To Scroll to top

getListView().setSelectionAfterHeaderView();

Note

try to call it in post because sometime listview is not yet created while you calling it's method

getListView().postDelayed(new Runnable() {          
    @Override
    public void run() {
        lst.setSelection(15);
    }
},100L);

Answer 4

您应该使用transcript mode ：

getListView().setTranscriptMode(ListView.TRANSCRIPT_MODE_NORMAL);

Answer 5

Setup a listener on your the list item being clicked, then use View.getTop() or View.getBottom() when clicked to get it's position within the parent. You can then use ListView.scrollTo(x, y) to scroll to the list item.

Answer 6

Yo can look For

listView.setSelectionFromTop(position, distanceFromHeader);

It will position the Item at position , specified pixels below the top of listview

Answer 7

You can use

smoothScrollToPosition(position)

Just increase the position of item with 1, and you will get the view of item.

getListView().smoothScrollToPosition(position + 1);

Answer 8

Using duration gives a better user experience. Use this, with duration added. Will scroll the item in position smoothly to the top of the listview.

int duration = 500;  //miliseconds
int offset = 0;      //fromListTop

listview.smoothScrollToPositionFromTop(position,offset,duration);

• descrease duration to make scrolling faster
