Android: ScrollView force to bottom

you should run the code inside the scroll.post like this:

scroll.post(new Runnable() {                @Override    public void run() {           scroll.fullScroll(View.FOCUS_DOWN);                  }});

scroll.fullScroll(View.FOCUS_DOWN) also should work.

Put this in a scroll.Post(Runnable run)

Kotlin Code

scrollView.post {   scrollView.fullScroll(View.FOCUS_DOWN)}

scroll.fullScroll(View.FOCUS_DOWN) will lead to the change of focus. That will bring some strange behavior when there are more than one focusable views, e.g two EditText. There is another way for this question.

    View lastChild = scrollLayout.getChildAt(scrollLayout.getChildCount() - 1);    int bottom = lastChild.getBottom() + scrollLayout.getPaddingBottom();    int sy = scrollLayout.getScrollY();    int sh = scrollLayout.getHeight();    int delta = bottom - (sy + sh);    scrollLayout.smoothScrollBy(0, delta);

This works well.

Kotlin Extension

fun ScrollView.scrollToBottom() {    val lastChild = getChildAt(childCount - 1)    val bottom = lastChild.bottom + paddingBottom    val delta = bottom - (scrollY+ height)            smoothScrollBy(0, delta)}
