ListView数据更新后，自动滚动到底部（聊天时常用）| Listview Scroll to the end of the list after updating the list_移动开发_编程开发_程序员俱乐部

If you would like to after you have updated by listAdapter, you want to make sure that the list is scrolled all the way to the bottom,

so that it displays the last element entered in the list. You  can  do this .

Method1:

mListView.setTranscriptMode(ListView.TRANSCRIPT_MODE_ALWAYS_SCROLL);

Method2:

set this attribute in XML

class="html">android:transcriptMode="alwaysScroll"

Method3:

if the above two methods fail, you can try this:

you can manually tell the list to scroll to the bottom by setting the list selection to the last row.

private void scrollMyListViewToBottom() {
    myListView.post(new Runnable() {
        @Override
        public void run() {
            // Select the last row so it will scroll into view...
            myListView.setSelection(myListAdapter.getCount() - 1);
        }
    });
}
