如何解决在Android中渲染epub文件
| 我有一个epub文件。我需要解压缩并解析epub文件，然后在Webview中进行渲染。在某处是否有分步教程。解决方法
访问此站点并下载该页面中提到的两个jar文件。
将这些库导入到您的android项目中
我通过两个活动实现了此任务：
1.）EpubReaderActivity-此活动将显示目录的列表视图
2.）ContentViewActivity-这将显示选定的章节。
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);
}
}
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\");
}
}
