什么是$ P $的状态pssed选项卡中的Andr​​oid [英] What's the state of a pressed Tab in Android

问题描述

我试图让我的tabicon当标签是pssed $ P $改变（即当它时，你PSS的标签$ P $，但还没有公布尚未改变颜色）。我如下创建的选择：

I'm trying to get my tabicon to change when a tab is pressed (i.e. when it changes color when you press the tab, but haven't released yet). I've created a selector as follows:

<?xml version="1.0" encoding="UTF-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android"> 
    <!-- Non focused states --> 
    <item android:state_focused="false" 
          android:state_selected="false" 
          android:state_pressed="false" 
          android:drawable="@drawable/ic_tab_icon1" /> 
    <item android:state_focused="false" 
          android:state_selected="true" 
          android:state_pressed="false" 
          android:drawable="@drawable/ic_tab_icon2" /> 

    <!-- Focused states --> 
    <item android:state_focused="true" 
          android:state_selected="false" 
          android:state_pressed="false" 
          android:drawable="@drawable/ic_tab_icon3" /> 
    <item android:state_focused="true" 
          android:state_selected="true" 
          android:state_pressed="false" 
          android:drawable="@drawable/ic_tab_icon4" /> 

    <!-- Pressed --> 
    <item android:state_pressed="true" 
          android:drawable="@drawable/ic_tab_icon5" /> 
</selector> 

然而，由于某种原因，只有前两个状态到达（仅ICON1和图标2时）。谁能告诉我正确的状态是个什么pssed $ P $，但没有选择选项卡？

However, for some reason only the first two states are reached (only icon1 and icon 2 are used). Can anyone tell me what the correct state is for a "pressed but not selected" tab?

推荐答案

这是默认的 tab_indicator.xml 为Android。从这个<一个有href="http://android.git.kernel.org/?p=platform/frameworks/base.git;a=blob;f=core/res/res/drawable/tab_indicator.xml;h=65df805d73ed4e759fe3f856bd5f6731bdb02ab0;hb=refs/heads/donut"相对=nofollow> gitkernal 。你必须维护所有这些国家。

this is the default tab_indicator.xml for android. got from this gitkernal. you have to maintain all these states.

<selector xmlns:android="http://schemas.android.com/apk/res/android"> 
    <!-- Non focused states --> 
    <item android:state_focused="false" android:state_selected="false" android:state_pressed="false" android:drawable="@drawable/ic_tab_north_normal" /> 
    <item android:state_focused="false" android:state_selected="true" android:state_pressed="false" android:drawable="@drawable/ic_tab_north_selected" /> 

    <!-- Focused states --> 
    <item android:state_focused="true" android:state_selected="false" android:state_pressed="false" android:drawable="@drawable/ic_tab_north_normal" /> 
    <item android:state_focused="true" android:state_selected="true" android:state_pressed="false" android:drawable="@drawable/ic_tab_north_selected" /> 

    <!-- Pressed --> 
    <item android:state_pressed="true" android:drawable="@drawable/ic_tab_north_normal" /> 
</selector>
