我添加库的罐子（我有两个，V13和v4），但错误依然存在。 谢谢你。

编辑：改变V13到V4后，很多错误都消失只剩下2

 私有类ScreenSlidePagerAdapter扩展FragmentStatePagerAdapter {
        公共ScreenSlidePagerAdapter（FragmentManager FM）{
            超（FM）;
        }
 

超（FM）;构造FragmentStatePageAdapter（FragmentManager）是不确定的。

和

 公开片段的getItem（INT位置）{
    返回ScreenSlidePageFragment.create（位置）;
}
 

公开片段的getItem（INT位置） - 返回类型是与FragmentStatePageAdapter.getItem（INT）不兼容的

将进口android.support.v13.app.FragmentActivity到进口android.support.v4.app.FragmentActivity

对于不确定的部分，试试这个语法：

 公共类ScreenSlidePagerAdapter扩展FragmentStatePagerAdapter {
    公共ScreenSlidePagerAdapter（android.support.v4.app.FragmentManager FM）{
        超（FM）;
    }
 

和

  @覆盖
    公共android.support.v4.app.Fragment的getItem（INT位置）{
        返回ScreenSlidePagerAdapter.create（位置）;
    }
 

原建议：你有没有添加到库构建路径？刚上项目和菜单项Java构建路径右键单击将陆续上市。选择此项，并添加库到您的路径。

I added the jar in libs (I have both, v13 and v4), but the error still persists. Thank you.

EDIT: After changing v13 to v4, a lot of errors are disappearing remaining only 2.

private class ScreenSlidePagerAdapter extends FragmentStatePagerAdapter {
        public ScreenSlidePagerAdapter(FragmentManager fm) {
            super(fm);
        }

super(fm); The constructor FragmentStatePageAdapter(FragmentManager) is undefined.

and

public Fragment getItem(int position) {
    return ScreenSlidePageFragment.create(position);
}

public Fragment getItem(int position) - the return type is incompatible with FragmentStatePageAdapter.getItem(int).

Change the "import android.support.v13.app.FragmentActivity" to "import android.support.v4.app.FragmentActivity"

For the undefined part, try this syntax:

public class ScreenSlidePagerAdapter extends FragmentStatePagerAdapter {
    public ScreenSlidePagerAdapter (android.support.v4.app.FragmentManager fm) {
        super(fm);
    }

and:

@Override
    public android.support.v4.app.Fragment getItem(int position) {
        return ScreenSlidePagerAdapter.create(position);
    }

Original suggestion: Have you added the libraries to your build path? Just right-click on the project and the menu item "Java Build Path" will be listed. Select this and add the libraries to your path.
