[英]Smooth scrolling in Android applications
I would like to add the smooth scrolling functionality into my application.我想将平滑滚动功能添加到我的应用程序中。 ie I have a huge text and I want to scroll it automatically (like in book readers).
即我有一个巨大的文本,我想自动滚动它(就像在书籍阅读器中一样)。
Could anyone offer any examples of smooth scrolling?谁能提供任何平滑滚动的例子?
Just put the view(s) you want to scroll inside a ScrollView.只需将要滚动的视图放入 ScrollView。 So to put some text in a scrolling area, put the text in a TextView, and then the TextView inside a ScrollView, like this:
因此,要将一些文本放入滚动区域,请将文本放入 TextView,然后将 TextView 放入 ScrollView,如下所示:
<ScrollView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<TextView
android:id="@+id/my_view_id"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>
</ScrollView>
Use reflection to update the ScrollView's Scroller:使用反射更新 ScrollView 的 Scroller:
Field mScroller;
mScroller = ScrollView.class.getDeclaredField("mScroller");
mScroller.setAccessible(true);
CustomScroller scroller = new CustomScroller(getContext(), new AccelerateInterpolator());
mScroller.set(this, scroller);
Use smoothScrollTo method (may have to setSmoothScrolligEnabled(true))使用 smoothScrollTo 方法(可能需要 setSmoothScrolligEnabled(true))
