Android でよくある正規表現を使えるやつ

最終更新日時 : 2016-01-05 20:33

そもそもは Linkify のWEBリンクがなんだかな, と思い.

使えそうなよくある正規表現がいくつか用意されていたのですな.

public static final Pattern WEB_URL = Pattern.compile(
    "((?:(http|https|Http|Https|rtsp|Rtsp):\\/\\/(?:(?:[a-zA-Z0-9\\$\\-\\_\\.\\+\\!\\*\\'\\(\\)"
  + "\\,\\;\\?\\&\\=]|(?:\\%[a-fA-F0-9]{2})){1,64}(?:\\:(?:[a-zA-Z0-9\\$\\-\\_"
  + "\\.\\+\\!\\*\\'\\(\\)\\,\\;\\?\\&\\=]|(?:\\%[a-fA-F0-9]{2})){1,25})?\\@)?)?"
  + "(?:" + DOMAIN_NAME + ")"
  + "(?:\\:\\d{1,5})?)"
  + "(\\/(?:(?:[" + GOOD_IRI_CHAR + "\\;\\/\\?\\:\\@\\&\\=\\#\\~"
  + "\\-\\.\\+\\!\\*\\'\\(\\)\\,\\_])|(?:\\%[a-fA-F0-9]{2}))*)?"
  + "(?:\\b|$)");

public static final Pattern PHONE
  = Pattern.compile(                
      "(\\+[0-9]+[\\- \\.]*)?"      
    + "(\\([0-9]+\\)[\\- \\.]*)?"   
    + "([0-9][0-9\\- \\.]+[0-9])");

public static final Pattern EMAIL_ADDRESS
  = Pattern.compile(
    "[a-zA-Z0-9\\+\\.\\_\\%\\-\\+]{1,256}" +
    "\\@" +
    "[a-zA-Z0-9][a-zA-Z0-9\\-]{0,64}" +
    "(" +
        "\\." +
        "[a-zA-Z0-9][a-zA-Z0-9\\-]{0,25}" +
     ")+"
  );

platform_frameworks_base/Patterns.java

すぐにそのまま使おう.


if (Patterns.WEB_URL.matcher(text).find()) {
  // do something
}

「厳格なのか?」でフィルターをつける場合.

// A match filter that only accepts odd numbers.
MatchFilter oddFilter = new MatchFilter() {
    public final boolean acceptMatch(CharSequence s, int start, int end) {
        int n = Character.digit(s.charAt(end-1), 10);
        return (n & 1) == 1;
    }
};

// Match all digits in the pattern but restrict links to only odd
// numbers using the filter.
Pattern pattern = Pattern.compile("[0-9]+");
Linkify.addLinks(text, pattern, "http://...", oddFilter, null);

Retrofit 2.0-beta でログを吐かせる

最終更新日時 : 2022-03-18 17:23

Retrofit

Okhttp 2.6.0+ では HTTPリクエスト/レスポンスのログ出力が可能なのだが,

New Logging Interceptor. The logging-interceptor subproject offers simple request and response logging. It may be configured to log headers and bodies for debugging. It requires this Maven dependency:

HttpLoggingInterceptor logging = new HttpLoggingInterceptor();
logging.setLevel(Level.BASIC);
client.networkInterceptors().add(logging);

okhttp/CHANGELOG.md at master · square/okhttp

残念なことに retrofit 2.0.0-beta2 での同梱は 2.5.0 .

<!-- Dependencies -->
<android.version>4.1.1.4</android.version>
<android.platform>16</android.platform>
<okhttp.version>2.5.0</okhttp.version>
<animal.sniffer.version>1.14</animal.sniffer.version>

retrofit/pom.xml at master · square/retrofit

なので logging-interceptor 2.6.0 で.

    <dependency>
      <groupId>com.squareup.okhttp</groupId>
      <artifactId>okhttp</artifactId>
      <version>${project.version}</version>
    </dependency>

okhttp/okhttp-logging-interceptor at master · square/okhttp

compile 'com.squareup.okhttp:logging-interceptor:2.6.0'

HttpLoggingInterceptor logging = new HttpLoggingInterceptor();  
logging.setLevel(Level.BASIC);
OkHttpClient client = new OkHttpClient();  
httpClient.interceptors().add(logging);
Retrofit retrofit = new Retrofit.Builder()  
   .baseUrl(API_BASE_URL)
   .addConverterFactory(GsonConverterFactory.create())
   .client(httpClient)
   .build();

出力.

stable で対応するのかな.
