问题描述
限时送ChatGPT账号..我的布局中有一个 EditText.以下是我目前拥有的属性:
I have an EditText on my layout. Below are the attributes I currently have:
<EditText
android:id="@+id/entryIdea"
android:layout_width="fill_parent"
android:layout_height="225sp"
android:gravity="top"
android:background="@android:drawable/editbox_background"
android:scrollbars="vertical"/>
但是,我可以看到滚动条,但无法使用鼠标/触摸滚动它.我认为如果我放置相应的侦听器,它可能会起作用,因为它适用于 TextView.显然不是.
However, I can see the scrollbar but can't scroll it with mouse/touch. I thought that it may works if I put the corresponding listener since it works on TextView. Apparently, it isn't.
EditText et = (EditText)findViewById(R.id.entryIdea);
et.setMovementMethod(new ScrollingMovementMethod());
你们能帮我解决这个问题吗?
Can you guys help me on this?
在此先感谢您.萨米
推荐答案
在你的 XML 中尝试设置 EditText
高度而不是在 layout_height
中,而是使用 android:lines
属性(顺便说一句,在设置字体大小以外的任何大小时,使用 sp 通常不是一个好习惯.在这种情况下使用 dp/dip 更自然).
In your XML try setting the EditText
height not in layout_height
, but rather use android:lines
attribute (btw, using sp is not usually a good practice when setting a size for anything except font size. Using dp/dip is more natural in this case).
同时将 layout_height
设置为 wrap_content
.否则,即使没有在代码中指定移动方法,您提供的 XML(带有我提到的更改)对我来说也能正常工作.
Meanwhile set layout_height
to wrap_content
. Otherwise the XML you presented (with the changes I've mentioned) worked fine for me even without specifying movement method in the code.
当然,当EditText中的实际文本行数大于android:lines属性时,滚动条就会出现.
And of course, the scroll bar will appear when the actual amount of lines of text in the EditText is larger than that, indicated in android:lines attribute.
