Render epub files in android

I have a epub file. 开发者_如何学JAVAI need to unzip and parse the epub file and render it in Webview. Is there a step by step tutorial somewhere.

1. Visit this site and download the two jar files mentioned in that page.
2. Import those libraries to your android project
3. I implemented this task using two activities :
   1.) EpubReaderActivity - this activity will display a list view of Table of Contents
   2.) ContentViewActivity - this will display the selected chapter.

EpubReaderActivity.java

public class EpubReaderActivity extends ListActivity 
{

private LayoutInflater inflater;
private List<RowData> contentDetails;
public static final String BOOK_NAME = "books/wodehouse.epub";

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    inflater = (LayoutInflater) getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
    contentDetails = new ArrayList<RowData>();
    AssetManager assetManager = getAssets();
    try {
        InputStream epubInputStream = assetManager.open(BOOK_NAME);
        Book book = (new EpubReader()).readEpub(epubInputStream);
        logContentsTable(book.getTableOfContents().getTocReferences(), 0);
    } catch (IOException e) {
        Log.e("epublib", e.getMessage());
    }

    CustomAdapter adapter = new CustomAdapter(this, R.layout.list,
            R.id.title, contentDetails);
    setListAdapter(adapter);
    getListView().setTextFilterEnabled(true);
}

private class CustomAdapter extends ArrayAdapter<RowData>{

    public CustomAdapter(Context context, int resource,
            int textViewResourceId, List<RowData> objects) {
        super(context, resource, textViewResourceId, objects);
    }

    private class ViewHolder{
        private View row;
        private TextView titleHolder = null;

        public ViewHolder(View row) {
            super();
            this.row = row;
        }

        public TextView getTitle() {
            if(null == titleHolder)
                titleHolder = (TextView) row.findViewById(R.id.title);
            return titleHolder;
        }
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        ViewHolder holder = null;
        TextView title = null;
        RowData rowData = getItem(position);
        if(null == convertView){
            convertView = inflater.inflate(R.layout.list, null);
            holder = new ViewHolder(convertView);
            convertView.setTag(holder);
        }
        holder = (ViewHolder) convertView.getTag();
        title = holder.getTitle();
        title.setText(rowData.getTitle());
        return convertView;
    }

}

private void logContentsTable(List<TOCReference> tocReferences, int depth) {
    if (tocReferences == null) {
        return;
    }
    for (TOCReference tocReference:tocReferences) {
        StringBuilder tocString = new StringBuilder();
        for (int i = 0; i < depth; i++) {
            tocString.append("\t");
        }
        tocString.append(tocReference.getTitle());
        RowData row = new RowData();
        row.setTitle(tocString.toString());
        row.setResource(tocReference.getResource());
        contentDetails.add(row);
        logContentsTable(tocReference.getChildren(), depth + 1);
    }
}

private class RowData{
    private String title;
    private Resource resource;

    public RowData() {
        super();
    }

    public String getTitle() {
        return title;
    }

    public Resource getResource() {
        return resource;
    }

    public void setTitle(String title) {
        this.title = title;
    }

    public void setResource(Resource resource) {
        this.resource = resource;
    }

}



@Override
protected void onListItemClick(ListView l, View v, int position, long id) {
    super.onListItemClick(l, v, position, id);
    RowData rowData = contentDetails.get(position);
    Intent intent = new Intent(MicroEpubReaderActivity.this, ContentViewActivity.class);
    intent.putExtra("display", new String(rowData.getResource().getData()));
    startActivity(intent);

}

}

ContentViewActivity.java

public class ContentViewActivity extends Activity {

WebView webView;

@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setContentView(R.layout.content);

    webView = (WebView) findViewById(R.id.webview);
    webView.getSettings().setJavaScriptEnabled(true);

    String displayString = getIntent().getExtras().getString("display");
    if(displayString != null)
        webView.loadData(displayString, "text/html", "utf-8");
}   
}

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

main.xml Use this with pkamalaruban's answer

If you want to use stage web view for rendering epub simply pass the epub directly....The android native web kit browser supports almost all formats for rendering.

var stageWebView:StageWebView = new StageWebView;
stageWebView.stage = stage;  
stageWebView.viewPort = new Rectangle(0, 0, stage.stageWidth, stage.stageHeight-100);  
stageWebView.loadURL("http://localhost/eboard.pdf"); // use any path

You dont require any zip/unzip or parsing....but in case you do not go for web view then you might need that...
