尝试这段代码以获得更好的性能

AssetManager mgr = getContext().getAssets();

try {

InputStream in = mgr.open(FileName,AssetManager.ACCESS_BUFFER);

String sHTML = streamToString(in);

in.close();

//display this html in the browser

WebView w = (WebView) findViewById(R.id.webview);

w.getSettings().setDefaultZoom(ZoomDensity.FAR);

w.loadDataWithBaseURL("file:///android_asset/", sHTML, "text/html", "utf-8", null);

} catch (IOException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

public static String StreamToString(InputStream in) throws IOException {

if(in == null) {

return "";

}

Writer writer = new StringWriter();

char[] buffer = new char[1024];

try {

Reader reader = new BufferedReader(new InputStreamReader(in, "UTF-8"));

int n;

while ((n = reader.read(buffer)) != -1) {

writer.write(buffer, 0, n);

}

} finally {

}

return writer.toString();

}
