使用默认的选择,长期pressing列表项导致其背景为两种颜色之间的过渡。
与一个替代选择下方的删除效果。根据这个问题,我需要一个动画来重现。我怎么会去这样做,在XML?
< XML版本=1.0编码=UTF-8&GT?;
<选择
的xmlns:机器人=http://schemas.android.com/apk/res/android>
<项目
机器人:STATE_ pressed =真正的>
<形状>
[固体
机器人:颜色=@色/ STATE_ pressed/>

解决方案
下面是list_selector_background的code:
<选择的xmlns:机器人=http://schemas.android.com/apk/res/android>
<项目安卓state_window_focused =假机器人:可绘制=@机器人:彩色/透明/>
<! -
尽管这两个点到同一资源,具有两种状态,以便
可绘制将走出pressed状态时无效本身。

<项目安卓state_focused =真正的机器人:state_enabled =假
机器人:STATE_ pressed =真正的机器人:可绘制=@可绘制/ list_selector_background_disabled/>
<项目安卓state_focused =真正的机器人:state_enabled =假
机器人:可绘制=@可绘制/ list_selector_background_disabled/>
<项目安卓state_focused =真正的机器人:STATE_ pressed =真
机器人:可绘制=@可绘制/ list_selector_background_transition/>
<项目安卓state_focused =假的Android版本:STATE_ pressed =真
机器人:可绘制=@可绘制/ list_selector_background_transition/>
<项目安卓state_focused =真
机器人:可绘制=@ +绘制/ list_selector_background_focus/>
< /选择器>
找到的on网络。
和它使用这种转型长期preSS点击:
<过渡的xmlns:机器人=http://schemas.android.com/apk/res/android>
<项目机器人:可绘制=@可绘制/ list_selector_background_ pressed/>
<项目机器人:可绘制=@可绘制/ list_selector_background_long preSS/>
< /转换>
找到的on网络太。
没有动画为该。请记住,让你的国家以相同的顺序,或者至少想想如果换成他们,顺序很重要。
Personnally,我喜欢当事情表现得有标准的方式,所以我只想让标准列表选择。
问候, 斯特凡
With the default selector, long-pressing a list item causes its background to transition between two colors.
Replacing the selector with the one below removes the effect. According to this question, I need an animation to reproduce it. How would I go about doing that in xml?
<?xml version="1.0" encoding="utf-8"?>
<selector
xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:state_pressed="true">
<shape>
<solid
android:color="@color/state_pressed" />
</shape>
</item>
<item
android:state_focused="true">
<shape>
<solid
android:color="@color/state_focused" />
</shape>
</item>
<item>
<shape>
<solid
android:color="@color/state_idle_grey" />
</shape>
</item>
</selector>
解决方案
Here is the code from list_selector_background :
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_window_focused="false" android:drawable="@android:color/transparent" />
<!--
Even though these two point to the same resource, have two states so
the drawable will invalidate itself when coming out of pressed state.
-->
<item android:state_focused="true" android:state_enabled="false"
android:state_pressed="true" android:drawable="@drawable/list_selector_background_disabled" />
<item android:state_focused="true" android:state_enabled="false"
android:drawable="@drawable/list_selector_background_disabled" />
<item android:state_focused="true" android:state_pressed="true"
android:drawable="@drawable/list_selector_background_transition" />
<item android:state_focused="false" android:state_pressed="true"
android:drawable="@drawable/list_selector_background_transition" />
<item android:state_focused="true"
android:drawable="@+drawable/list_selector_background_focus" />
</selector>
Found on the web.
And it uses this transition for long press clicks :
<transition xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@drawable/list_selector_background_pressed" />
<item android:drawable="@drawable/list_selector_background_longpress" />
</transition>
Found on the web too .
There is no animation for that. And remember to keep you states in the same order, or at least think about it if you swap them, order is important.
Personnally, I like when things behave in a standard way, so I would just let the standard list selector.
