下面是我pageviewer类
package com.android.pageviewers;
import java.util.ArrayList;
import java.util.List;
import android.content.Intent;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentActivity;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;
import android.support.v4.view.ViewPager;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
public class PageViewActivity extends FragmentActivity implements Communicator{
MyPageAdapter pageAdapter;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_page_view);
// viewPdf();
List<Fragment> fragments = getFragments();
pageAdapter = new MyPageAdapter(getSupportFragmentManager(), fragments);
ViewPager pager = (ViewPager)findViewById(R.id.pager);
// ViewPager pager = new ViewPager(this);
// pager.setId(R.id.pager);
pager.setAdapter(pageAdapter);
}
/*
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View contentView = inflater.inflate(R.layout.activity_page_view, container, false);
List<Fragment> fragments = getFragments();
pageAdapter = new MyPageAdapter(getSupportFragmentManager(), fragments);
ViewPager pager = (ViewPager)contentView.findViewById(R.id.pager);
pager.setAdapter(pageAdapter);
return contentView;
}
*/
private List<Fragment> getFragments(){
List<Fragment> fList = new ArrayList<Fragment>();
fList.add(MyFragment2.newInstance("Fragment 1"));
fList.add(MyFragment2.newInstance("Fragment 2"));
fList.add(MyFragment2.newInstance("Fragment 3"));
return fList;
}
private class MyPageAdapter extends FragmentPagerAdapter {
private List<Fragment> fragments;
public MyPageAdapter(FragmentManager fm, List<Fragment> fragments) {
super(fm);
this.fragments = fragments;
}
@Override
public Fragment getItem(int position) {
return this.fragments.get(position);
}
@Override
public int getCount() {
return this.fragments.size();
}
}
}
是fragment2类
package com.android.plugpdfsample;
import java.io.File;
import java.io.InputStream;
import com.epapyrus.plugpdf.SimpleDocumentReader;
import com.epapyrus.plugpdf.SimpleDocumentReaderListener;
import com.epapyrus.plugpdf.SimpleReaderFactory;
import com.epapyrus.plugpdf.core.viewer.DocumentState;
import com.epapyrus.plugpdf.core.viewer.ReaderView;
import android.content.Intent;
import android.content.res.AssetManager;
import android.net.Uri;
import android.os.Bundle;
import android.os.Environment;
import android.support.v4.app.Fragment;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;
public class MyFragment extends Fragment {
public static final String EXTRA_MESSAGE = "EXTRA_MESSAGE";
// create a listener for receiving provide pdf loading results
SimpleDocumentReaderListener m_listener = new SimpleDocumentReaderListener() {
@Override
public void onLoadFinish(DocumentState.OPEN state) {
}
};
public static final MyFragment newInstance(String message)
{
MyFragment f = new MyFragment();
Bundle bdl = new Bundle(1);
bdl.putString(EXTRA_MESSAGE, message);
f.setArguments(bdl);
return f;
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
s");
Log.i("onCreateView1", "startView v = inflater.inflate(R.layout.myfragment_layout, container, false);
String extStorageDirectory = Environment.getExternalStorageDirectory().toString();
File fl =new File(Environment.getExternalStorageDirectory(), "/1.pdf");
ReaderView readerView = (ReaderView) v.findViewById(R.id.pdfview);
readerView.openFile(fl.toString(),"");
Log.i("onCreateView1", "ends");
return v;
}
}
下面为PDF文件的XML标签
<com.android.ab.custom.PDFView
android:id="@+id/pdfview"
android:background="#FF0000FF"
android:padding="5dp"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
请发表相关的代码。 – Okas 2014-10-16 14:59:37
