Question

这是我的Xml：

<constant name="struts.convention.package.locators.basePackage" value="com.infotech.project.web.action"/>

这是我的主要动作：

 <RelativeLayout
            android:id="@+id/content"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:layout_above="@id/footer"
            android:background="#000000"
            android:gravity="center" >

            <android.support.v4.view.ViewPager
                android:id="@+id/pager"
                android:layout_width="fill_parent"
                android:layout_height="wrap_content"
                android:textColor="#ffffff" >

                <android.support.v4.view.PagerTabStrip
                    android:id="@+id/pager_title_strip"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:layout_gravity="top"
                    android:background="#d3d3d3"
                    android:paddingBottom="10dp"
                    android:paddingTop="10dp"
                    android:textColor="#000000" />
            </android.support.v4.view.ViewPager>
        </RelativeLayout>

这是我的viewpageAdapter类：

 public class MainActivity extends FragmentActivity {   
        @Override
        protected void onCreate(Bundle savedInstanceState) {
                    viewPager = (ViewPager) findViewById(R.id.pager);
            mAdapter = new TabsPagerAdapter(getSupportFragmentManager());
            viewPager.setAdapter(new                   ViewPagerAdapter(getSupportFragmentManager()));

    }
    }

据我所知，我认为使用默认的PagerTabStrip是不可能的。

为您的设计尝试两种解决方案中的任何一种，

使用按钮作为viewpager的标签

使用自定义PagerTitleStrip

在layout.xml中

<com.xxx.yyy.PagerSlidingTabStrip

                android:layout_weight="1"
                android:background="@android:color/white"></android.support.v4.view.ViewPager>

在您的活动中，

    PagerSlidingTabStrip mPagerSlidingTabStrip = (PagerSlidingTabStrip) findViewById(R.id.pager_strip);

            mPagerSlidingTabStrip.setShouldExpand(true);
 mPagerSlidingTabStrip.setViewPager(mViewPager);
            mPagerSlidingTabStrip.setOnPageChangeListener(this);

在您的values文件夹中创建attrs.xml并添加以下代码：

<?xml version="1.0" encoding="utf-8"?>
<resources>

    <declare-styleable name="PagerSlidingTabStrip">
        <attr name="pstsIndicatorColor" format="color" />
        <attr name="pstsUnderlineColor" format="color" />
        <attr name="pstsDividerColor" format="color" />
        <attr name="pstsIndicatorHeight" format="dimension" />
        <attr name="pstsUnderlineHeight" format="dimension" />
        <attr name="pstsDividerPadding" format="dimension" />
        <attr name="pstsTabPaddingLeftRight" format="dimension" />
        <attr name="pstsScrollOffset" format="dimension" />
        <attr name="pstsTabBackground" format="reference" />
        <attr name="pstsShouldExpand" format="boolean" />
        <attr name="pstsTextAllCaps" format="boolean" />
    </declare-styleable>

</resources>

我认为是主要的解决方案，它是ViewPager的自定义按钮。只需创建自定义按钮，如果单击则切换颜色。并添加ViewPager，它可以更改当前按钮。多数民众赞成......
