代碼部分

整合到項目：

S1.添加依賴 compile ‘com.elvishew:xlog:1.4.0‘或匯入library源碼庫；

S2.初始化log；

S3.調用log；

 

API：

初始化LogConfiguration config = new LogConfiguration.Builder()    .logLevel(BuildConfig.DEBUG ? LogLevel.ALL             // Specify log level, logs below this level won‘t be printed, default: LogLevel.ALL        : LogLevel.NONE)    .tag("MY_TAG")                                         // Specify TAG, default: "X-LOG"    .t()                                                   // Enable thread info, disabled by default    .st(2)                                                 // Enable stack trace info with depth 2, disabled by default    .b()                                                   // Enable border, disabled by default    .jsonFormatter(new MyJsonFormatter())                  // Default: DefaultJsonFormatter    .xmlFormatter(new MyXmlFormatter())                    // Default: DefaultXmlFormatter    .throwableFormatter(new MyThrowableFormatter())        // Default: DefaultThrowableFormatter    .threadFormatter(new MyThreadFormatter())              // Default: DefaultThreadFormatter    .stackTraceFormatter(new MyStackTraceFormatter())      // Default: DefaultStackTraceFormatter    .borderFormatter(new MyBoardFormatter())               // Default: DefaultBorderFormatter    .addObjectFormatter(AnyClass.class,                    // Add formatter for specific class of object        new AnyClassObjectFormatter())                     // Use Object.toString() by default    .addInterceptor(new BlacklistTagsFilterInterceptor(    // Add blacklist tags filter        "blacklist1", "blacklist2", "blacklist3"))    .addInterceptor(new MyInterceptor())                   // Add a log interceptor    .build();Printer androidPrinter = new AndroidPrinter();             // Printer that print the log using android.util.LogPrinter consolePrinter = new ConsolePrinter();             // Printer that print the log to console using System.outPrinter filePrinter = new FilePrinter                      // Printer that print the log to the file system    .Builder("/sdcard/xlog/")                              // Specify the path to save log file    .fileNameGenerator(new DateFileNameGenerator())        // Default: ChangelessFileNameGenerator("log")    .backupStrategy(new NeverBackupStrategy())             // Default: FileSizeBackupStrategy(1024 * 1024)    .logFlattener(new MyFlattener())                       // Default: DefaultFlattener    .build();XLog.init(                                                 // Initialize XLog    config,                                                // Specify the log configuration, if not specified, will use new LogConfiguration.Builder().build()    androidPrinter,                                        // Specify printers, if no printer is specified, AndroidPrinter(for Android)/ConsolePrinter(for java) will be used.    consolePrinter,filePrinter);log列印：XLog.d("Simple message")XLog.d("My name is %s", "Elvis");XLog.d("An exception caught", exception);XLog.d(object);XLog.d(array);XLog.json(unformattedJsonString);XLog.xml(unformattedXmlString);
