我在xml中定义了android.support.v4.view.PagerTabStrip
,如下所示:
<android.support.v4.view.ViewPager xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/pager"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">
<!--
This title strip will display the currently visible page title, as well as the page
titles for adjacent pages.
-->
<android.support.v4.view.PagerTabStrip android:id="@+id/pager_title_strip"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="top"
android:background="#33b5e5"
android:textColor="#fff"
android:paddingTop="4dp"
android:paddingBottom="4dp" />
</android.support.v4.view.ViewPager>
如何更改TabIndicater
颜色?它可以通过setTabIndicatorColor(int color)以编程方式进行更改,但我需要找到一种方法在xml中执行此操作。
答案 0 :(得分:9)
主要方法是使类扩展PagerTabStrip
,例如,名为MyPagerTabStrip
的类:
package com.example.View; /// change this package to yourselves.
public class MyPagerTabStrip extends PagerTabStrip
{
public MyPagerTabStrip(Context context, AttributeSet attrs)
{
super(context, attrs);
final TypedArray a = context.obtainStyledAttributes(attrs,
R.styleable.MyPagerTabStrip);
setTabIndicatorColor(a.getColor(
R.styleable.MyPagerTabStrip_indicatorColor, Color.BLUE));
a.recycle();
}
}
在res / values文件夹中新建一个名为 attrs.xml 的文件,该文件的内容为:
<?xml version="1.0" encoding="utf-8"?>
<declare-styleable name="MyPagerTabStrip">
<attr name="indicatorColor" format="reference|color" />
</declare-styleable>
同一个文件夹,新文件(如果不存在),名为 styles.xml ,将下面的代码放在文件中:
<style name="Pager">
<item name="android:textColor">#ffffff</item>
<item name="indicatorColor">#6f8dc5</item>
</style>
最后,您的布局xml文件是:
<android.support.v4.view.ViewPager xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/pager"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">
<!--
This title strip will display the currently visible page title, as well as the page
titles for adjacent pages.
-->
<com.example.view.MyPagerTabStrip android:id="@+id/pager_title_strip"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="top"
android:background="#33b5e5"
android:textColor="#fff"
android:paddingTop="4dp"
android:paddingBottom="4dp" />
