Androidでepubのコンテンツを表示するためにwebviewを使用していますが、コンテンツを表示することはできますが、画像を表示することはできません。この問題を解決するのに役立つ人はいますか?
表示に使用したコードは次のとおりです::
public class MainActivity extends Activity {
WebView webview;
String line, line1 = "", finalstr = "";
int i = 0;
Book book;
String linez;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
webview = (WebView) findViewById(R.id.tv);
AssetManager assetManager = getAssets();
try {
// find InputStream for book
InputStream epubInputStream = assetManager
.open("widget.epub");
// Load Book from inputStream
book = (new EpubReader()).readEpub(epubInputStream);
// Log the book's authors
Log.i("author", " : " + book.getMetadata().getAuthors());
// Log the book's title
Log.i("title", " : " + book.getTitle());
/* Log the book's coverimage property */
Bitmap coverImage =BitmapFactory.decodeStream(book.getCoverImage().getInputStream());
Log.i("epublib", "Coverimage is " + coverImage.getWidth() + " by " + coverImage.getHeight() + " pixels");
// Log the tale of contents
logTableOfContents(book.getTableOfContents().getTocReferences(), 0);
} catch (IOException e) {
Log.e("epublib exception", e.getMessage());
}
Spine spine = book.getSpine();
List<SpineReference> spineList = spine.getSpineReferences() ;
int count = spineList.size();
TextView tv=new TextView(getApplicationContext());
tv.setText(Integer.toString(count));
StringBuilder string = new StringBuilder();
for (int i = 0; count > i; i++) {
Resource res = spine.getResource(i);
try {
InputStream is = res.getInputStream();
BufferedReader reader = new BufferedReader(new InputStreamReader(is));
try {
while ((line = reader.readLine()) != null) {
linez = string.append(line + "\n").toString();
}
} catch (IOException e) {e.printStackTrace();}
//do something with stream
} catch (IOException e) {
e.printStackTrace();
}
}
webview.loadData(linez, "text/html", "utf-8");
}
@SuppressWarnings("unused")
private void logTableOfContents(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());
Log.i("TOC", tocString.toString());
try {
InputStream is = tocReference.getResource().getInputStream();
BufferedReader r = new BufferedReader(new InputStreamReader(is));
while ((line = r.readLine()) != null) {
Log.v("line" + i, Html.fromHtml(line).toString());
line1 = line1.concat(Html.fromHtml(line).toString());
}
finalstr = finalstr.concat("\n").concat(line1);
i++;
} catch (IOException e) {
}
logTableOfContents(tocReference.getChildren(), depth + 1);
}
webview.loadDataWithBaseURL("", finalstr, "text/html", "UTF-8", "");
}
}
