设置TextView的衰落的Andr​​oid 4.0.3

问题描述

我只是想实现的Andr​​oid 4.0.3淡入淡出效果的TextView ;但是，这是行不通的。

I've just tried to implement the fade effect for TextView in Android 4.0.3; however, it doesn't work.

fadingEdge="horizontal"
singleLine="true"
ellipsize="marquee"

这code完全适用于2.3.7及以下，但不工作的4.0.3。我不知道为什么会这样呢？以及如何淡入淡出效果的TextView ？

This code works perfectly for 2.3.7 and below, but not working for 4.0.3.I'm wondering why is that so? and how to make fade effect for TextView?

我的问题是一样的这一个：http://groups.google.com/group/android-developers/browse_thread/thread/97131b20de8b2ebd ，但没有答案。

推荐答案

这是一个有点晚，但可以帮助人们谁拥有了同样的问题。

It is a bit late, but that may help people who have the same question.

我已经对不同的手机这个问题，它可能来自是：

I have had this problem on different phones, and it could come from that :

• 在Android 4.0.x的，似乎TextView的必须要成为焦点，否则褪色效果将无法正常工作。因此，尝试添加这样的：

• on Android 4.0.x, it seems that the TextView have to be focusable, otherwise fade effect won't work. So try adding this :

机器人：可调焦=真机器人：focusableInTouchMode =真正的

android:focusable="true"android:focusableInTouchMode="true"

如果不工作，你可以尝试机器人：行=1，但我认为，安卓SINGLELINE =真，这是德precated，效果更好

if that does not work, you could try android:lines="1", but i think that android:singleLine="true", which is deprecated, works better

有时候，你需要以编程方式调用的setSelected（真）上的TextView得到淡入淡出效果。请检查此链接：Is有没有办法让ellipsize =＆QUOT;字幕＆QUOT;一直滚动？

sometimes, you need to programmatically call setSelected(true) on the textView to get the fade effect. Please check this link : Is there a way to make ellipsize="marquee" always scroll?
