我很难搞清楚如何在android中实现更复杂的主题/风格情况.
我已经研究过Android提供的不同的造型/主题教程,但是在我的情况下它们不符合要求.
该(蒸馏)情况如下:我创建了一个应用程序的定制tabwidget,我需要能够以品牌不同风格的应用程序(主题).
该XML的tabwidget(基于http://joshclemm.com/blog/?p=136):
布局/ tabs_bg.xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/tabsLayout" android:layout_width="fill_parent"
android:layout_height="fill_parent" android:background="@drawable/tab_bg_selector"
android:padding="10dip" android:gravity="center" android:orientation="vertical">
<LinearLayout android:layout_width="wrap_content"
android:layout_height="wrap_content" android:orientation="horizontal"
android:gravity="center">
<ImageView
android:src="@drawable/star_fav_empty"
android:layout_height="24px"
android:layout_width="24px"
android:id="@+id/tabsImage"
android:paddingRight="5dip"></ImageView>
<TextView
android:id="@+id/tabsText"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Hallowaaaaa"
android:textSize="15dip"
android:textColor="?android:textColorTertiary"/>
</LinearLayout>
</LinearLayout>

绘制/ tab_bg_selector.xml:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<!-- Active tab -->
<item android:state_selected="true" android:state_focused="false"
android:state_pressed="false" android:drawable="@drawable/tab_bg_selected" />
<!-- Inactive tab -->
<item android:state_selected="false" android:state_focused="false"
android:state_pressed="false" android:drawable="@drawable/tab_bg_unselected" />
<!-- Pressed tab -->
<item android:state_pressed="true" android:state_enabled="false" android:drawable="@android:color/transparent" />
<!-- Selected tab (using d-pad) -->
<item android:state_focused="true" android:state_selected="true"
android:state_pressed="false" android:drawable="@android:color/transparent" />

然后,我想定义样式如下:
值/ MyBaseStyle.xml
<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="MyBaseStyle" parent="@android:style/Theme.Light">
</style>
</resources>

值/ MySubStyle1.xml
<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="MySubStyle1" parent="MyBaseStyle">
</style>
</resources>

值/ MySubStyle2.xml
<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="MySubStyle2" parent="MyBaseStyle">
</style>
</resources>

这里的重大问题是:
1.如何在MyBaseStyle.xml中放置渐变或颜色,并在tab_bg_selected.xml和tab_bg_unselected.xml中使用它而不是硬编码的渐变/颜色?
2.如何从MySubStyle1.xml和MySubStyle2.xml中分别覆盖我在MyBaseStyle.xml中定义的渐变/颜色,以便我的自定义tabwidget相应地设置样式?
备注:我真的希望能够分别在MyBaseStyle.xml,MySubStyle1.xml和MySubStyle2.xml中定义渐变/颜色(而不是在多个不同的XML文件中定义多种不同的颜色),以便能够保持"样式"在一个文件中.这样,我可以为我的应用程序外包品牌.
有人可以帮我完成这个吗?
在/res/values的colors.xml中为每个主题设置颜色
<?xml version="1.0" encoding="utf-8"?>
<resources>
<color name="themeB_textColor">#e8e8e8</color>
<color name="themeA_textColor">#fff</color>
</resources>

然后以编程方式为给定主题设置视图颜色?
//at on create grab the selected theme however it has been set - ie: through preferences
if(theme=='themeA')
{
super.setTheme(R.style.ThemeA);
Color textColor = getResources().getColor(R.color.themeA_textColor);
}
//later
applyTextColors(textView1,textView2...)
//make a function for applying colors
public void applyTextColors(TextView... tvs)
{
for(TextView tv : tvs){tv.setTextColor(textColor);}
}
