so far i have read how to load "normal" html webpages in a webview .. so far I pass the URL containing the path of my text file but it loads nothing. this is my method:
@Override
public void onSelected(String url) {
ViewerFragment viewer = (ViewerFragment) getSupportFragmentManager()
.findFragmentById(R.id.view_fragment);
if (viewer == null || !viewer.isInLayout()) {
Intent showContent = new Intent(getApplicationContext(),
ViewerFragment.class);
showContent.setData(Uri.parse(url));
startActivity(showContent);
} else {
viewer.updateUrl(url);
}
}
and the viewer fragment got this:
public class ViewerFragment extends Fragment{
private WebView viewer = null;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
viewer = (WebView) inflater
.inflate(R.layout.details_fragment, container, false);
return viewer;
}
public void updateUrl(String newUrl) {
if (viewer != null) {
viewer.loadUrl(newUrl);
}
}
}
but keep getting this screen:
any ideas how to do this? =/ I already tried googling a bit but didnt find much info about it... actually found almost none. So any help would be appreciated.
Try reading the contents of the text file and prefixing the text with <html><body> then append </body></html> then use the WebView method loadData(...).
Example:
StringBuilder sb = new StringBuilder("<html><body>");
sb.append(readTextFile());
sb.append("</body></html>");
myWebView.loadData(sb.ToString(), "text/html", "UTF-8");
public String readTextFile(String filename) {
// Open and read the contents of <filename> into
// a single string then return it
}
