有没有办法以编程方式将滚动视图滚动到特定的编辑文本? [英] Is there a way to programmatically scroll a scroll view to a specific edit text?

问题描述

我有一个很长的滚动视图活动.这是一个包含用户必须填写的各种字段的表单.我在表单的中间有一个复选框，当用户选中它时，我想滚动到视图的特定部分.有没有办法以编程方式滚动到 EditText 对象(或任何其他视图对象)?

I have a very long activity with a scrollview. It is a form with various fields that the user must fill in. I have a checkbox half way down my form, and when the user checks it I want to scroll to a specific part of the view. Is there any way to scroll to an EditText object (or any other view object) programmatically?

另外，我知道这可以使用 X 和 Y 坐标，但我想避免这样做，因为表单可能会因用户而异.

Also, I know this is possible using X and Y coords but I want to avoid doing this as the form may changed from user to user.

推荐答案

private final void focusOnView(){
        your_scrollview.post(new Runnable() {
            @Override
            public void run() {
                your_scrollview.scrollTo(0, your_EditBox.getBottom());
            }
        });
    }
