[英]load textfile in webview android
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. 到目前为止,我已经阅读了如何在webview中加载“普通”html网页..到目前为止,我传递了包含我的文本文件路径的URL,但它没有加载任何内容。 this is my method: 这是我的方法:
@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: 并且查看器片段得到了这个:
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: 但继续得到这个屏幕:
any ideas how to do this? 任何想法如何做到这一点? =/ I already tried googling a bit but didnt find much info about it... actually found almost none. = /我已经尝试了谷歌搜索但没有找到关于它的很多信息...实际上几乎找不到。 So any help would be appreciated. 所以任何帮助将不胜感激。
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(...)
. 尝试阅读文本文件的内容,并在文本前加上<html><body>
然后追加</body></html>
然后使用WebView
方法loadData(...)
。
Example: 例:
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
}
