html 페이지가 있는지 여부 체크는 어떻게 하나요?

Question

가령 webview를 실행하기 전 로딩할 html페이지가 있는지 여부를 간단히 체크할 수 있는 방법이 있나요..?

Answer 1

> url 검사

 

public static boolean checkURL(CharSequence input) {

    if (TextUtils.isEmpty(input)) {

        return false;

    }

    Pattern URL_PATTERN = Patterns.WEB_URL;

    boolean isURL = URL_PATTERN.matcher(input).matches();

    if (!isURL) {

        String urlString = input + "";

        if (URLUtil.isNetworkUrl(urlString)) {

            try {

                new URL(urlString);

                isURL = true;

            } catch (Exception e) {

            }

        }

    }

    return isURL;

}

 

 

> get html

 

HttpClient httpclient = new DefaultHttpClient(); // Create HTTP Client

HttpGet httpget = new HttpGet("http://yoururl.com"); // Set the action you want to do

HttpResponse response = httpclient.execute(httpget); // Executeit

HttpEntity entity = response.getEntity(); 

InputStream is = entity.getContent(); // Create an InputStream with the response

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

StringBuilder sb = new StringBuilder();

String line = null;

while ((line = reader.readLine()) != null) // Read line by line

    sb.append(line + "\n");

 

String resString = sb.toString(); // Result is here

 

is.close(); // Close the stream
