我试图让我的 tabicon 在按下选项卡时更改（即，当您按下选项卡时它会改变颜色，但尚未释放）。我创建了一个选择器，如下所示：

<?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>

但是，由于某种原因，只能达到前两个状态（仅使用 icon1 和 icon 2）。谁能告诉我“按下但未选中”选项卡的正确状态是什么？

这是tab_indicator.xml来自Android 2.2：

<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/tab_unselected" />
    <item android:state_focused="false" android:state_selected="true" android:state_pressed="false" android:drawable="@drawable/tab_selected" />

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

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

你什么地方都没有android:state_pressed="true"。尝试更改您的选择器，使其看起来更像 Android 使用的。

这是安卓的默认设置tab_indicator.xml。从这个gitkernal得到。你必须保持所有这些状态。

<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>
