Question

我有scrollview包含自定义的相对布局，在点击时展开和折叠。我需要将scrollview位置更改为scrollview布局的最后一个位置。我试图通过以下代码滚动到最后但它仍然没有滚动到最后扩展。

scrollview.post(new Runnable() {
        @Override
        public void run() {
            main_content.scrollTo(0, scrollview.getBottom());
        }
    });

这是我的xml

Answer 1

尝试以下方面的焦点位置：

listView.post(new Runnable() {

    @Override
    public void run() {
        listView.setSelection(focusedPosition);
        // position for highlight view
        View v = getViewByPosition(0, list);  
        v.setBackgroundResource(R.color.black); // highlight color
    }
});

将焦点更改为Scrollview的最后一个项目结束
