Android 视图被截断

Question

就像在标题中一样，当et_note_desc_value的长度足以到达button2以下时，此 EditText 的末尾将被切断。

我已经尝试过 SO 的可能解决方案，但我猜它们不起作用。

这是我的代码：

<?xml version="1.0" encoding="utf-8"?>

        android:textColor="#fff"
        android:layout_alignParentBottom="true"
        android:layout_centerHorizontal="true"/>
</RelativeLayout>

是什么原因以及如何解决？

我会尝试将 ScrollView 的 ( sv_note_desc_value ) 高度更改为match_parent而不是wrap_content 。 我最好的猜测是它被截断了，因为内容的大小导致它在不应该换行的时候换行。
