在web视图Android的负载文本文件 [英] load textfile in webview android
问题描述
到目前为止，我已经阅读如何加载在一个web视图正常的HTML网页.. 到目前为止，我传递一个包含我的文本文件的路径的网址，但它加载什么。 这是我的方法：
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);
}
}
和观众的片段得到这样的：
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);
}
}
}
但不断收到这样的屏幕：

推荐答案
尝试阅读的文本文件和$ P $的pfixing与＆LT文本内容; HTML＆GT;＆LT;身体GT; 然后追加＆LT; / BODY＆GT;＆LT; / HTML＆GT; 然后使用的WebView 方法 loadData（...）。
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(...).
例如：
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
}
