Scrollview Not Scrolling Down Completely

I'm building a chat-like application that displays text the user inputs to the screen using a scrollview. What I'm doing is auto-scrolling the scrollview down as more text is appen

Solution 1:

I looked around, and found that some other people have run into the same problem.

I solved this problem using this piece of code:

finalScrollViewscrollView= (ScrollView) findViewById(R.id.scroll_view);
scrollView.post(newRunnable() {
    publicvoidrun() {
        scrollView.fullScroll(View.FOCUS_DOWN);
    }
});

Hopefully this can help somebody out there!

Solution 2:

Its late but may help some one with this issue.. It takes around 200 miniseconds to add the last element and update it for a scrollView so this will surely work.

voidscrollDown()
{
    Thread scrollThread = new Thread(){
        publicvoidrun(){
            try {
                sleep(200);
                ChatActivity.this.runOnUiThread(new Runnable() {
                    publicvoidrun() {
                        myScrollView.fullScroll(View.FOCUS_DOWN);
                    }    
                });
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    };
    scrollThread.start();
}

Just call scrollDown(); after adding element to scrollView.

Solution 3:

Did it this way on Xamarin Android project:

var scrollView = FindViewById<ScrollView>(Resource.Id.scrolview); 

scrollView.Post(() =>
{
    scrollView.FullScroll(FocusSearchDirection.Down);
});

Thanks to OP.

Solution 4:

@OverridepublicvoidonClick(View v) {

            scview_ashora = findViewById(R.id.scview_ashora);
            scview_ashora.fullScroll(ScrollView.FOCUS_DOWN);

            scview_ashora.postDelayed(newRunnable() {
                @Overridepublicvoidrun() {
                    //replace this line to scroll up or down
                    scview_ashora.fullScroll(ScrollView.FOCUS_DOWN);
                }
            }, 1000000L);


        }
    });
