How to set ListView Scroll position to bottom in android?

Question

I know this question is asked several times before but my situation is bit different from other questions.

I have a listview and initially i want to set the scroll position to the bottom of the list.

I have try 2 ways.

1st one

mCommentListView.setSelection(mAdaptor.getCount()-1);

2nd one

mCommentListView.post(new Runnable() {
    @Override
    public void run() {
        mCommentListView.setSelection(mAdaptor.getCount()-1);
    }
});

So my problem is both of above code working properly with the emulator but it is not working with the real device.

What have i missed?

Solution 1

try this. the below code is working fine for me.

give time delay 500 for load listview then call setselection method.

commentslistview.postDelayed(new Runnable() {
    @Override
    public void run() {
        commentslistview.setSelection(commentsarraylist.size());
    }
}, 500);

Solution 2

Did you set these in your ListView?

android:stackFromBottom="true"
android:transcriptMode="alwaysScroll"

Solution 3

listView.setAdapter(adapter);
listView.setSelection(position);

Solution 4

:D I just set:

mListView.setSelection(adapter.getCount() - 1);

And my Layout

<ListView
    android:id="@+id/tb_body"
    android:layout_width="match_parent"
    android:layout_height="fill_parent"
    android:choiceMode="singleChoice"
    android:stackFromBottom="true"
    tools:ignore="NestedScrolling" >
</ListView>

SET

android:choiceMode="singleChoice"
android:stackFromBottom="true"

Hope it works fine with you.

Solution 5

Try this

srollView.getViewTreeObserver().addOnGlobalLayoutListener(
            new ViewTreeObserver.OnGlobalLayoutListener() {

            @Override
            public void onGlobalLayout() {

                mScrollView.post(new Runnable() {

                    @Override
                    public void run() {


                        scrollView.smoothScrollTo(0,scrollView.getBottom());
                        }
                    });
                }
        });
