我正在使用杰克沃顿的ViewPagerIndicator在我的LinePageIndicator中添加ViewPager。我遇到的问题是，当我按照用法说明操作时，我会收到以下错误（无法解析方法'findViewById（int）'＆amp;'getSupportFragmentManager（）'）在这方面：
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.lay_menufragment, container, false);
//galeria de imagenes
mSectionsPagerAdapter = new SectionsPagerAdapter(getChildFragmentManager());
mViewPager = (ViewPager) rootView.findViewById(R.id.pager);
mSectionsPagerAdapter.addfragments(PlaceholderFragment.newInstance(imagenes[0]));
mSectionsPagerAdapter.addfragments(PlaceholderFragment.newInstance(imagenes[1]));
mSectionsPagerAdapter.addfragments(PlaceholderFragment.newInstance(imagenes[2]));
mViewPager.setAdapter(mSectionsPagerAdapter);
//Set the pager with an adapter
ViewPager pager = (ViewPager)findViewById(R.id.pager);
pager.setAdapter(new SectionsPagerAdapter(getSupportFragmentManager()));
//Bind the title indicator to the adapter
LinePageIndicator lineIndicator = (LinePageIndicator)findViewById(R.id.lines);
lineIndicator.setViewPager(pager);
return rootView;
}
以下是我Fragment的完整代码：
import android.content.Context;
import android.content.Intent;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;
import android.support.v4.view.ViewPager;

public class FmMenu extends Fragment {
int[] imagenes = {
R.drawable.jeans,
R.drawable.blusas,
R.drawable.leggings,
};

@Override

mViewPager = (ViewPager) rootView.findViewById(R.id.pager);
mSectionsPagerAdapter.addfragments(PlaceholderFragment.newInstance(imagenes[0]));

mViewPager.setAdapter(mSectionsPagerAdapter);
//Set the pager with an adapter
ViewPager pager = (ViewPager)findViewById(R.id.pager);
pager.setAdapter(new SectionsPagerAdapter(getSupportFragmentManager()));
//Bind the title indicator to the adapter
LinePageIndicator lineIndicator = (LinePageIndicator)findViewById(R.id.lines);
lineIndicator.setViewPager(pager);
return rootView;
}
public class SectionsPagerAdapter extends FragmentPagerAdapter {
List<Fragment> fragmentos;
public SectionsPagerAdapter(FragmentManager fm) {
super(fm);
fragmentos = new ArrayList<Fragment>();
}
public void addfragments(Fragment xfragment){
fragmentos.add(xfragment);
}
@Override
public Fragment getItem(int position) {
return fragmentos.get(position);
}
@Override
public int getCount() {
return fragmentos.size();
}
}
public static class PlaceholderFragment extends Fragment implements View.OnClickListener {
private static final String ARG_IMAGE = "imagen";
private int imagen;
public static PlaceholderFragment newInstance(int imagen) {
PlaceholderFragment fragment = new PlaceholderFragment();
Bundle args = new Bundle();
args.putInt(ARG_IMAGE, imagen);
fragment.setArguments(args);
fragment.setRetainInstance(true);
return fragment;
}
public void onClick(View v){
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if(getArguments() != null) {
imagen = getArguments().getInt(ARG_IMAGE);
}
}
public PlaceholderFragment() {
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_menu, container, false);
ImageView mainimages = (ImageView) rootView.findViewById(R.id.imageView1);
mainimages.setImageResource(imagen);
mainimages.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Intent activityIntent = new Intent();
Intent intent = new Intent();
switch(imagen){
case R.drawable.jeans:
intent = new Intent(getActivity(), JeansActivity.class);
break;
case R.drawable.blusas:
intent = new Intent(getActivity(), BlusasActivity.class);
break;
case R.drawable.leggings:
intent = new Intent(getActivity(), LeggingsActivity.class);
break;
}
startActivity(intent);
}
});
return rootView;
}
}
}
当我实现com.viewpagerindicator.LinePageIndicator时，我的布局中也出现以下错误：
