Android ScrollView displaces other items

问题

I tried all decisions from https://stackoverflow.com/questions/14811032/scrollview-not-scrolling-at-all but my ScrollView doesn't work right yet.

我尝试了 https://stackoverflow.com/questions/14811032/scrollview-not-scrolling-at-all 中的所有解决方案，但我的 ScrollView 仍然无法正常工作。

I tried to nest the TextView inside the ScrollView without the LinearView, to set android:layout_height of the ScrollView to 0dp (not appearing at all in that case), to set several values of fill_parent, match_parent or wrap_content, to delete and restore the padding values and so on.

我尝试将 TextView 嵌套在 ScrollView 中，而不使用 LinearView，将 ScrollView 的 android:layout_height 设置为 0dp（在这种情况下根本不显示），尝试设置 fill_parent、match_parent 或 wrap_content 等多个值，删除和恢复 padding 值等等。

Here's my whole long code of the activity.

以下是我整个长代码的活动内容。

我找到了决定。关键是仅为ScrollView设置android:layout_weight值。

请注意，我只翻译了XML中的文本内容，代码部分保持原样。

So I found the decision. The point is to set android:layout_weight value only for the ScrollView.
