代碼部分
集成到項目：
S1.添加依賴 compile ‘com.elvishew:xlog:1.4.0‘或導入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.Log Printer consolePrinter = new ConsolePrinter(); // Printer that print the log to console using System.out Printer 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打印： 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);

S2.初始化logger；
S3.調用logger；
API：
初始化 FormatStrategy formatStrategy = PrettyFormatStrategy.newBuilder() .showThreadInfo(false) // (Optional) Whether to show thread info or not. Default true .methodCount(0) // (Optional) How many method line to show. Default 2 .methodOffset(7) // (Optional) Hides internal method calls up to offset.
