错误充气类android.support.v4.view.ViewPager [英] Error inflating class android.support.v4.view.ViewPager

问题描述

我一直在试图建立一个寻呼机我的应用程序，在＆LT运行;采用-SDK安卓的minSdkVersion =10机器人：targetSdkVersion =15/＆GT; 我按照我写的code <一个href="http://mobile.tutsplus.com/tutorials/android/android-user-interface-design-horizontal-view-paging/">this博客文章。

I've been trying to create a Pager for my application that runs on <uses-sdk android:minSdkVersion="10" android:targetSdkVersion="15" /> I wrote my code according to this blog post.

XML的寻呼机活动：

<?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>

$ C $下适配器：

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;
    }
}

code的活性

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);
    }
}

由于某些原因，当我运行这个程序，我得到这个下面的错误列表：

for some reason, when I run this app, I get this following error list:

所以，我知道它的失败，因为我使用了 android.support.v4.view.ViewPager ，我试着玩了，改变为纯 ViewPager 并导入 android.support.v13 ，但它并没有帮助...

so, I know it's failing because I'm using the android.support.v4.view.ViewPager, I tried playing with that and changing to plain ViewPager and importing android.support.v13 but it didn't help...

在如何解决这一问题的任何想法？

any thoughts on how to fix this?

推荐答案

请确保你在一个公共文件夹放置库，比如在你的项目库。

Make sure that you place your libraries in a common folder such as libs in your project.

右键单击罐子，然后选择构建路径，然后单击添加到构建路径。

Right click on the jar, then select Build Path and click on Add to Build Path.

这将您的库添加到您的项目。如果一切正常，你可以看到它在项目生成的文件夹被称为引用的库

That will add your library to your project. If everything is correct, you can see it in a generated "folder" in the project called "Referenced Libraries"
