我正在用 Paul Siegmann http://www.siegmann.nl/epublib/android的图书馆制作一个 EPub 阅读器
我将目录提取到 aListView中，该项目链接到 a WebView，显示所选章节的内容。
我在显示只有纯文本元素的 E-Pub 文件时没有发现任何问题，但是当涉及到包含 Html 元素（链接、图像）的 E-Pub 文件时，它无法显示。
根据我的情况，有人知道如何在 WebView 上呈现 Html 元素吗？
这是我的课程：
public class EPubReaderActivity extends ListActivity
{
private LayoutInflater inflater;
private List<RowData> contentDetails;
public static final String BOOK_NAME = "ferring.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(EPubReaderActivity.this, ContentViewActivity.class);
try {
intent.putExtra("display", new String(rowData.getResource().getData()));
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
startActivity(intent);
}
}
内容类：
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.web);
webView.getSettings().setJavaScriptEnabled(true);
String displayString = getIntent().getExtras().getString("display");
if(displayString != null)
webView.loadData(displayString, "text/html", "utf-8");
}
}
