Android选项卡textcolor选择器忽略state_pressed [英] Android tabs textcolor selector ignores state_pressed

问题描述

我创建了自己的android主题来更改操作栏标签的外观.问题在于textcolor选择器似乎忽略了state_pressed属性，因此即使按下此选项卡，选项卡文本的颜色也始终相同.其他状态没有问题，例如，可以正确识别state_selected且所选选项卡具有文本颜色，该颜色与未选中的选项卡文本颜色不同.

此外，我还为选项卡背景创建了选择器，并且与state_pressed一起使用时效果很好(如果按下了选项卡，则背景颜色已更改).

I have created my own android theme to change the look of the actionbar tabs. The problem is that textcolor selector seems to ignore state_pressed attribute, so the color of tab text is always the same, even if this tab is pressed. There is no problem with other states, for example state_selected is correctly recognized and selected tab has text color, which is different from unselected tabs text color.

What is more, i have also created selector for tabs background and it works fine with state_pressed (if the tab is pressed, it's backround color is changed).

我的代码有几段:

styles.xml:

styles.xml:

<style name="Theme.MyTheme" parent="android:Theme.Holo.Light.DarkActionBar">
    <item name="android:actionBarTabStyle">@style/Theme.MyTheme.TabStyle</item>
    <item name="android:actionBarTabTextStyle">@style/Theme.MyTheme.TabTextStyle</item>
</style>

...

<style name="Theme.MyTheme.TabStyle"
       parent="@android:style/Widget.Holo.Light.ActionBar.TabView">
    <item name="android:background">@drawable/background_selector</item>
</style>

<style name="Theme.MyTheme.TabTextStyle"
       parent="@android:style/Widget.Holo.Light.ActionBar.TabText">
    <item name="android:textColor">@color/textcolor_selector</item>
</style>

background_selector.xml:

background_selector.xml:

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_selected="false" android:state_pressed="false">
        <shape>
            <solid android:color="#00ff00"/>
        </shape>
    </item>

    <item android:state_selected="false" android:state_pressed="true">
        <shape>
            <solid android:color="#0000ff"/>
        </shape>
    </item>

    <item android:state_selected="true" android:state_pressed="false">
        <shape>
            <solid android:color="#ff0000"/>
        </shape>
    </item>

    <item android:state_selected="true" android:state_pressed="true">
        <shape>
            <solid android:color="#ffff00"/>
        </shape>
    </item>
</selector>

textcolor_selector.xml

textcolor_selector.xml

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_selected="true" android:state_pressed="false"
          android:color="#ff0000"/>
    <item android:state_selected="true" android:state_pressed="true"
          android:color="#0000ff"/>
    <item android:state_selected="false" android:state_pressed="false"
          android:color="#ffff00"/>
    <item android:state_selected="false" android:state_pressed="true"
          android:color="#00ff00"/>
</selector>

我尝试了一切都没有成功-state_pressed属性似乎被忽略，但仅在textcolor_selector中.请帮助我理解和解决此问题.

I have tried everything without success - state_pressed attribute seems to be ignored, but only in textcolor_selector. Please, help me understand and solve this problem.

推荐答案

查看部分-提到Note: The custom style applied to titleTextStyle should use TextAppearance.Holo.Widget.ActionBar.Title as the parent style.-也许在那里进行更改可能有助于解决问题.

Review the Customize the Text Color section of the ActionBar Styling documentation - it mentions that Note: The custom style applied to titleTextStyle should use TextAppearance.Holo.Widget.ActionBar.Title as the parent style. - perhaps a change there might help correct the problem.

另一个值得一看的地方是此处 c1>部分-显示了android:actionBarTabTextStyle的示例，该示例可能有助于为您排序.

Another place to look would be here under the Example theme section - it shows an example of android:actionBarTabTextStyle that might help get things sorted for you.
