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?

Where are you invoking those method calls? Post more complete code. – Gustie

from Asynactask OnPostExecute(). – Blunder

Try this: mCommentListView.setSelection(mCommentListView.getCount() - 1); – Abbatial

And when is the AsyncTask started? Post your code for the Activity and the list adapter. – Gustie

@JoelFernandes i tried but no luck :( – Blunder

@kaluwila Did you try that with the first method? Also, try giving a number and see if it is working that way. Ex; mCommentListView.setSelection(5); – Abbatial

@ JoelFernandes yeah you got a point hmm it is not going to work with any number it will always set to first item.but anly in the device working fine with the emulater – Blunder

see #3607030 – Bruiser

@kaluwila Hmm that's strange. Can you post all the code that's related to the ListView? – Abbatial

@Shayan pourvata that is what i have already tried. – Blunder

Answer 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);

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());
                        }
                    });
                }
        });

hyy what is the srollView? hear i am dealing with a listview – Blunder

scrollView is object of a ScrollView here .But science u are dealing with a list view you can try to to have a the listview in side of a scrollView. – Tailband

@ Biplab putting a listview inside scrollview is not a good practice in android anyway thanks a lot for your help. – Blunder

Answer 5

: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.
