How to scroll to bottom in a ScrollView on activity startup

I am displaying some data in a ScrollView. On activity startup (method onCreate) I fill the ScrollView with data and want to scroll to the bottom.

I tried to use getScrollView().fullScroll(ScrollView.FOCUS_DOWN). This works when I make it as an action on button click but it doesn't work in the onCreate method.

Is there any way how to scroll the ScrollView to the bottom on activity startup? Th开发者_C百科at means the view is already scrolled to the bottom when first time displayed.

It needs to be done as following:

    getScrollView().post(new Runnable() {

        @Override
        public void run() {
            getScrollView().fullScroll(ScrollView.FOCUS_DOWN);
        }
    });

This way the view is first updated and then scrolls to the "new" bottom.

Put the following code after your data is added:

final ScrollView scrollview = ((ScrollView) findViewById(R.id.scrollview));
scrollview.post(new Runnable() {
    @Override
    public void run() {
        scrollview.fullScroll(ScrollView.FOCUS_DOWN);
    }
});

This works for me:

scrollview.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
    @Override
    public void onGlobalLayout() {
        scrollview.post(new Runnable() {
            public void run() {
                scrollview.fullScroll(View.FOCUS_DOWN);
            }
        });
    }
});

You can do this in layout file:

                android:id="@+id/listViewContent"
                android:layout_width="wrap_content"
                android:layout_height="381dp" 
                android:stackFromBottom="true"
                android:transcriptMode="alwaysScroll">

 scrollView.postDelayed(new Runnable() {
        @Override
        public void run() {
            scrollView.fullScroll(ScrollView.FOCUS_DOWN);
        }
    },1000);

Try this

    final ScrollView scrollview = ((ScrollView) findViewById(R.id.scrollview));
    scrollview.post(new Runnable() {
       @Override
       public void run() {
         scrollview.fullScroll(ScrollView.FOCUS_DOWN);
       }
    });

Right after you append data to the view add this single line:

yourScrollview.fullScroll(ScrollView.FOCUS_DOWN);

This is the best way of doing this.

scrollView.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
        @Override
        public void onGlobalLayout() {
            scrollView.post(new Runnable() {
                @Override
                public void run() {
                    scrollView.fullScroll(View.FOCUS_DOWN);
                }
            });
        }
});

After initializing your UI component and fill it with data. add those line to your on create method

Runnable runnable=new Runnable() {
        @Override
        public void run() {
            scrollView.fullScroll(ScrollView.FOCUS_DOWN);
        }
    };
    scrollView.post(runnable);
