我想改变" Tab底线颜色"我按照这个步骤:
1.在我的styles.xml
文件中:
<resources>
<!-- Base application theme. -->
<style name="AppTheme" parent="android:Theme.Holo.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="android:actionBarTabStyle">@style/ActionBarTabStyle.Dgrey</item>
</style>
<style name="ActionBarTabStyle.Dgrey" parent="@android:style/Widget.Holo.ActionBar.TabView">
<item name="android:background">@drawable/tab_indicator_ab_dgrey</item>
</style>
</resources>
2。在tab_indicator_ab_dgrey
我有:
<?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/tab_unselected_dgrey" />
<item android:state_focused="false" android:state_selected="true" android:state_pressed="false" android:drawable="@drawable/tab_selected_dgrey" />
<!-- Focused states -->
<item android:state_focused="true" android:state_selected="false" android:state_pressed="false" android:drawable="@drawable/tab_unselected_focused_dgrey" />
<item android:state_focused="true" android:state_selected="true" android:state_pressed="false" android:drawable="@drawable/tab_selected_focused_dgrey" />
<!-- Pressed -->
<!-- Non focused states -->
<item android:state_focused="false" android:state_selected="false" android:state_pressed="true" android:drawable="@drawable/tab_unselected_pressed_dgrey" />
<item android:state_focused="false" android:state_selected="true" android:state_pressed="true" android:drawable="@drawable/tab_selected_pressed_dgrey" />
<!-- Focused states -->
<item android:state_focused="true" android:state_selected="false" android:state_pressed="true" android:drawable="@drawable/tab_unselected_pressed_dgrey" />
<item android:state_focused="true" android:state_selected="true" android:state_pressed="true" android:drawable="@drawable/tab_selected_pressed_dgrey" />
</selector>
3。在我的可绘制文件夹(hdpi,mdpi,xhdpi,xxhdpi)中我有这些文件:
- tab_selected_dgrey.9.png
- tab_selected_focused_dgrey.9.png
- tab_selected_pressed_dgrey.9.png
- tab_unselected_dgrey.9.png
- tab_unselected_focused_dgrey.9.png
- tab_unselected_pressed_dgrey.9.png
在我的drawable文件夹中我有:
tab_indicator_ab_dgrey.xml
档案
最后,这是我的manifest.xml
:
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name="ch.studentgrades.StudentGrades"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
我不知道为什么(我按照教程)当我运行应用程序时没有改变任何东西,标签行颜色保持蓝色。
答案 0 :(得分:0)
这answer解决了我的问题。
设置标签后添加此代码:
TabHost host = (TabHost)view.findViewById(R.id.tab_host);
TabWidget widget = host.getTabWidget();
for(int i = 0; i < widget.getChildCount(); i++) {
View v = widget.getChildAt(i);
// Look for the title view to ensure this is an indicator and not a divider.
TextView tv = (TextView)v.findViewById(android.R.id.title);
if(tv == null) {
continue;
}
v.setBackgroundResource(R.drawable.tab_indicator_ab_dgrey);
}
然后,您可以从styles.xml
<item name="android:actionBarTabStyle">@style/ActionBarTabStyle.Dgrey</item>
和
<style name="ActionBarTabStyle.Dgrey" parent="@android:style/Widget.Holo.ActionBar.TabView">
<item name="android:background">@drawable/tab_indicator_ab_dgrey</item>
</style>
