为了方便日志管理，创建一个日志工具类。
开发过程中使用日志DEBUG = true发布程序时关闭日志DEBUG = false
public class LogUtil{// true:打印日志，false:关闭日志private static final boolean DEBUG = true;// 日志标签private static final String TAG = "PhoneSafer";// Send a VERBOSE log messagepublic static void v(String msg){if (DEBUG)Log.v(TAG, msg);}public static void v(Object msg){v(msg.toString());}public static void v(String tag, String msg){v(msg);}// Send a WARN log messagepublic static void w(String msg){if (DEBUG)Log.w(TAG, msg);}public static void w(Object msg){w(msg.toString());}// Send an ERROR log messagepublic static void e(String msg){if (DEBUG)Log.e(TAG, msg);}public static void e(Object msg){e(msg.toString());}public static void i(String msg){if (DEBUG)Log.i(TAG, msg);}public static void i(Object msg){i(msg.toString());}// Send a DEBUG log message.public static void d(String msg){if (DEBUG)Log.d(TAG, msg);}public static void d(Object msg){d(msg.toString());}/*-------------------------------------------------------分割线 -------------------------------------------------------*/public static void println(String printInfo){if (DEBUG && null != printInfo){System.out.println(printInfo);}}public static void print(String printInfo){if (DEBUG && null != printInfo){System.out.print(printInfo);}}/** * 打印类的基本信息 */public static void printBaseInfo(){if (DEBUG){StringBuffer strBuffer = new StringBuffer();StackTraceElement[] stackTrace = new Throwable().getStackTrace();strBuffer.append("; class:").append(stackTrace[1].getClassName()).append("; method:").append(stackTrace[1].getMethodName()).append("; number:").append(stackTrace[1].getLineNumber()).append("; fileName:").append(stackTrace[1].getFileName());println(strBuffer.toString());}}public static void printFileNameAndLinerNumber(){if (DEBUG){StringBuffer strBuffer = new StringBuffer();StackTraceElement[] stackTrace = new Throwable().getStackTrace();strBuffer.append("; fileName:").append(stackTrace[1].getFileName()).append("; number:").append(stackTrace[1].getLineNumber());println(strBuffer.toString());}}public static int printLineNumber(){if (DEBUG){StringBuffer strBuffer = new StringBuffer();StackTraceElement[] stackTrace = new Throwable().getStackTrace();strBuffer.append("; number:").append(stackTrace[1].getLineNumber());println(strBuffer.toString());return stackTrace[1].getLineNumber();} else{return 0;}}public static void printMethod(){if (DEBUG){StringBuffer strBuffer = new StringBuffer();StackTraceElement[] stackTrace = new Throwable().getStackTrace();strBuffer.append("; number:").append(stackTrace[1].getMethodName());println(strBuffer.toString());}}public static void printFileNameAndLinerNumber(String printInfo){if (null == printInfo || !DEBUG){return;}StringBuffer strBuffer = new StringBuffer();StackTraceElement[] stackTrace = new Throwable().getStackTrace();strBuffer.append("; fileName:").append(stackTrace[1].getFileName()).append("; number:").append(stackTrace[1].getLineNumber()).append("\n").append((null != printInfo) ? printInfo : "");println(strBuffer.toString());}public static void showStrictMode(){if (DEBUG){StrictMode.setThreadPolicy(new StrictMode.ThreadPolicy.Builder().detectDiskReads().detectDiskWrites().detectNetwork().penaltyLog().build());StrictMode.setVmPolicy(new StrictMode.VmPolicy.Builder().detectLeakedSqlLiteObjects().detectLeakedClosableObjects().penaltyLog().penaltyDeath().build());}}}
