扩展类android.support.v4.view.ViewPager时出错

概述我一直在尝试为我的应用程序创建一个Pager,它运行在<uses-sdkandroid：minSdkVersion=“10”android：targetSdkVersion=“15”/>我根据thisblogpost编写了我的代码.寻呼机活动的XML：<?xmlversion="1.0"encoding="utf-8"?><LinearLayoutxmlns:android="http://schem

我一直在尝试为我的应用程序创建一个Pager,它运行在< uses-sdk android：minSdkVersion =“10”androID：targetSdkVersion =“15”/>我根据this blog post编写了我的代码.

寻呼机活动的XML：

<?xml version="1.0" enCoding="utf-8"?><linearLayout xmlns:androID="http://schemas.androID.com/apk/res/androID"    androID:layout_wIDth="match_parent"    androID:layout_height="match_parent"    androID:orIEntation="vertical" >    <androID.support.v4.vIEw.VIEwPager        androID:ID="@+ID/instructionsVIEwPager"        androID:layout_wIDth="match_parent"        androID:layout_height="match_parent" /> </linearLayout>

适配器代码：

public class MyPagerAdapter extends PagerAdapter {    @OverrIDe    public int getCount() {        // Todo auto-generated method stub        return 2;    }    @OverrIDe    public boolean isVIEwFromObject(VIEw arg0, Object arg1) {        return (arg0 == ((VIEw) arg1));    }    @OverrIDe    public voID destroyItem(VIEwGroup container, int position, Object object) {        ((VIEwPager) container).removeVIEw((VIEw) object);    }    @OverrIDe    public Object instantiateItem(VIEwGroup container, int position) {        LayoutInflater inflater = (LayoutInflater) container.getContext()                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);        int resID = 0;        switch (position) {        case 1:            resID = R.layout.instructions_page1;            break;        case 2:            resID = R.layout.instructions_page2;            break;        }        VIEw vIEw = inflater.inflate(resID, null);        ((VIEwPager) container).addVIEw(vIEw, 0);        return vIEw;    }}

活动代码

public class Instructions extends Activity {    public voID onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentVIEw(R.layout.instructions);        MyPagerAdapter adapter = new MyPagerAdapter();        VIEwPager pager = (VIEwPager) findVIEwByID(R.ID.instructionsVIEwPager);        pager.setAdapter(adapter);        pager.setCurrentItem(0);    }}

出于某种原因,当我运行这个应用程序时,我得到以下错误列表：

所以,我知道它失败了,因为我正在使用androID.support.v4.vIEw.VIEwPager,我尝试使用它并更改为普通VIEwPager并导入androID.support.v13但它没有帮助…

关于如何解决这个问题的任何想法？

解决方法:

确保将库放在公共文件夹中,例如项目中的libs.

右键单击jar,然后选择Build Path并单击Add to Build Path.

这会将您的库添加到您的项目中.如果一切正确,您可以在名为“Referenced librarIEs”的项目中生成的“文件夹”中看到它
