Question

发布包含'č'，'š'和'ž'等字符的单词时遇到问题。这些角色都在Android键盘中。调用startActivity（Jsoup_result）后，应用程序崩溃了。而textview也不显示这个字符。它只显示。起初它甚至不会检测它们，只会留下一个空白区域（使用UTF-8参数返回字符）。

起初我认为这个问题只与textview有关。当我输入这个字符时，应用程序就会关闭（它并没有说应用程序已停止工作）。也没有错误。

protected String doInBackground(String... params) {

    String url = "http://www.ap-ljubljana.si/vozni_red2/VR2.php";
    HttpPost post = new HttpPost(url);
    List<NameValuePair> parameters = new ArrayList<NameValuePair>();

    parameters.add(new BasicNameValuePair("VSTOP_IME", vhod));
    parameters.add(new BasicNameValuePair("IZSTOP_IME", izhod));

    try {
        UrlEncodedFormEntity entity = new UrlEncodedFormEntity(parameters);
        HttpClient client = new DefaultHttpClient();
        post.setEntity(entity);
        HttpResponse response = client.execute(post);
        html_response = EntityUtils.toString(response.getEntity(), UTF-8);

    } catch (UnsupportedEncodingException e) {
        e.printStackTrace();
    } catch (ClientProtocolException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }


    return null;
}
    @Override
    protected void onPostExecute(String s) {
        super.onPostExecute(s);

        Intent Jsoup_result = new Intent(getActivity(), HtmlCode.class);
        Jsoup_result.putExtra("html", html_response);
        startActivity(Jsoup_result);
    }

}

以下是活动中显示Jsoup

解析结果的代码

public class HtmlCode extends Activity{
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    Intent intent = getIntent();
    String value = intent.getStringExtra("html");
    setContentView(R.layout.htmlkoda);
    TextView tv_html = (TextView) findViewById(R.id.tv_html);


    Document document = Jsoup.parse(value);
    Elements tr = document.select("select[name=VSTOP_ID]");
    Elements options = tr.select("select > option");
    value = "";

    for(Element element : options)
    {
        value += element.text() + "\n";
    }

    tv_html.setText(value);

}

}

Answer 1

html_response = EntityUtils.toString(response.getEntity(), UTF-8);

那不编译。你了：

html_response = EntityUtils.toString(response.getEntity(), "UTF-8");

但随着网站的推出

<meta http-equiv="Content-Type" content="text/html; charset=windows-1250">

你最好使用

html_response = EntityUtils.toString(response.getEntity());

我刚在textView中的onPostExecute中显示了html_response。对我而言看起来还不错。

<强>更新

在更好地意识到必须完成Windows-1250的某些功能后，我尝试了

html_response = EntityUtils.toString(response.getEntity(), "windows-1250");

而且......宾果！这些字符现在与使用浏览器发布时相同。

发布'č'，'š'和'ž'后应用关闭
