Android 如何在webview中显示html页面的全部内容文本
我在阅读Android 如何在webview中显示html页面的全部内容文本,android,html,webview,Android,Html,Webview,我在阅读webview中的内容时发现了一个问题。我已经尝试了，但无法解决 我在webview中显示了一个html页面。我需要一个字符串html页面的内容 java代码 WebView mainContent = (WebView)layout.findViewById(R.id.webView1); mainContent.getSettings().setJavaScriptEnabled(true); WebSettings webSettings = m
webviewwebview字符串html页面的内容
java代码
WebView mainContent = (WebView)layout.findViewById(R.id.webView1);
mainContent.getSettings().setJavaScriptEnabled(true);
WebSettings webSettings = mainContent.getSettings();
webSettings.setJavaScriptEnabled(true);
webSettings.setBuiltInZoomControls(true);
mainContent.requestFocusFromTouch();
mainContent.setWebViewClient(new WebViewClient() {
@Override
public void onPageFinished(WebView view, String url) {
super.onPageFinished(view, url);
mainContent.loadUrl("javascript:window.HTMLOUT.processHTML('<html>'+document.getElementsByTagName('html')[0].innerHTML+'</html>');");
}
});
mainContent.setWebChromeClient(new WebChromeClient());
mainContent.loadUrl("file:///android_asset/"+filename.get(position));
webSettings.setDefaultFontSize(40);
我没有看到我的任何日志。如何在字符串中获取HTML
页面的内容（文本）。我做错了什么？提前感谢您是否尝试启动该页面的GET请愿书
responseString
是字符串中的HTML页面。例如：
class RequestTask extends AsyncTask<String, String, String>{
@Override
protected String doInBackground(String... uri) {
HttpClient httpclient = new DefaultHttpClient();
HttpResponse response;
String responseString = null;
try {
response = httpclient.execute(new HttpGet(uri[0]));
StatusLine statusLine = response.getStatusLine();
if(statusLine.getStatusCode() == HttpStatus.SC_OK){
ByteArrayOutputStream out = new ByteArrayOutputStream();
response.getEntity().writeTo(out);
out.close();
responseString = out.toString();
} else{
//Closes the connection.
response.getEntity().getContent().close();
throw new IOException(statusLine.getReasonPhrase());
}
} catch (ClientProtocolException e) {
//TODO Handle problems..
} catch (IOException e) {
//TODO Handle problems..
}
return responseString;
}
@Override
protected void onPostExecute(String result) {
super.onPostExecute(result);
//Do anything with response..
}
}
我是通过这种方式得到内容的
mainContent.getSettings().setJavaScriptEnabled(true);
WebSettings webSettings = mainContent.getSettings();
webSettings.setJavaScriptEnabled(true);
webSettings.setBuiltInZoomControls(true);
mainContent.requestFocusFromTouch();
mainContent.setWebChromeClient(new WebChromeClient());
mainContent.loadUrl("file:///android_asset/"+filename.get(position));
mainContent.setWebViewClient(new WebViewClient() {
@Override
public void onPageFinished(WebView view, String url) {
super.onPageFinished(view, url);
mainContent.setWebViewClient(null);
mainContent.loadUrl("javascript:window.HTMLOUT.processHTML('<div>'+document.getElementsByTagName('div')[0].innerHTML+'</div>');");
从web或本地文件查看此帖子？@NickF从web我已经在webview中显示了此文件我需要获取您想要在web视图中显示html字符串吗？@Suru否我需要在webview中显示的html页面中的文本无法理解您的代码。。我需要从该WebView获取文本，这是一个使用AsyncTask获取URL的请求。它以字符串形式返回HTML页面（返回responseString）。您可以使用webview url并启动此任务以字符串形式检索其内容。显示类型不匹配：无法从AsyncTask转换为StringIt's not working。。我没有得到任何错误，但也应用程序minimized@MakeitSimple日志和应用程序中没有强制关闭的内容？
