自定义Android日志输出工具类

<span style="font-size:18px;">/*** *----------- 版本说明--------------- * 1.0.0实现的功能： * a、根据配置文件，控制了是否需要打印各种调试日志的信息； * b、该工具的使用是全局单例模式实现的，具体的使用步骤如下： * （1）首先在资源文件中自定义一个资源变量is_print_log，格式为： <bool name="is_print_log">true</bool>； * （2）其次，在第一次使用的时候实例化，Logger.getInstance(Context); * （3）最后，可以直接调用对应的方法即可，如Logger.i("",""); * 2.0.0实现的功能： * a、添加了将日志保存在本地的功能； * 3.0.0预实现的功能：删除本地的日志以及本地的日志回滚； */package com.keyisoftware.utils;import java.io.BufferedWriter;import java.io.File;import java.io.FileWriter;import java.io.IOException;import java.text.SimpleDateFormat;import java.util.Date;import android.content.Context;import android.os.Environment;import android.util.Log;/** * 自定义的日志输出,建议当程序发布的时需要在configs.xml文件中将is_print_log设置为false； *  * @author keyisoftware@163.com * @version 2.0.0 */public class KyLog {public enum LogType {debug, error, info, verbose, warn}private static final String TAG = "KyLog_";private static KyLog log;/** 是否打印调试日志 */private static boolean isPrintDebugLog = false;/** 是否写日志到本地 */private static boolean isWriteToSdcard = false;/** 项目文件夹 */private static String projectDirectory;private static String DebugDir = "";private static String ErrorDir = "";private static String VerboseDir = "";private static String WarnDir = "";private static String InfoDir = "";/** * 单例模式 *  * @param context *            上下文 */private KyLog(Context context) {try {// TODO:此种方法不好之处在于必须关联到R文件了。isPrintDebugLog = context.getResources().getBoolean(R.bool.is_print_log);isWriteToSdcard = context.getResources().getBoolean(R.bool.is_write_to_sdcard);projectDirectory = context.getResources().getString(R.string.project_directory);// 创建所有的文件夹/** 构建目录路径 **/if (projectDirectory == null || projectDirectory == "") {projectDirectory = "KyUtils";}String LogDirectory = Environment.getExternalStorageDirectory().getAbsolutePath() + "/" + projectDirectory + "/Log/";DebugDir = LogDirectory + "/Debug/";ErrorDir = LogDirectory + "/Error/";VerboseDir = LogDirectory + "/Verbose/";WarnDir = LogDirectory + "/Warn/";InfoDir = LogDirectory + "/Info/";/** 创建文件目录 **/File dir = new File(DebugDir);if (!dir.exists()) {dir.mkdirs();}dir = new File(ErrorDir);if (!dir.exists()) {dir.mkdirs();}dir = new File(VerboseDir);if (!dir.exists()) {dir.mkdirs();}dir = new File(WarnDir);if (!dir.exists()) {dir.mkdirs();}dir = new File(InfoDir);if (!dir.exists()) {dir.mkdirs();}} catch (Exception e) {Log.e(TAG, "Can't find is_print_log in configs.xml file!");}}/** * 初始化单例模式 *  * @param context *            上下文 * @return 日志的单例模式 */public static KyLog getInstance(Context context) {if (log == null) {log = new KyLog(context);}return log;}public static void d(String tag, String msg) {if (isPrintDebugLog) {Log.d(TAG + tag, msg);}if (isWriteToSdcard) {writeLogToSdCard(LogType.debug, tag, msg);}}public static void e(String tag, String msg) {if (isPrintDebugLog)Log.e(TAG + tag, msg);if (isWriteToSdcard) {writeLogToSdCard(LogType.error, tag, msg);}}public static void i(String tag, String msg) {if (isPrintDebugLog)Log.i(TAG + tag, msg);if (isWriteToSdcard) {writeLogToSdCard(LogType.info, tag, msg);}}public static void v(String tag, String msg) {if (isPrintDebugLog)Log.v(TAG + tag, msg);if (isWriteToSdcard) {writeLogToSdCard(LogType.verbose, tag, msg);}}public static void w(String tag, String msg) {if (isPrintDebugLog)Log.w(TAG + tag, msg);if (isWriteToSdcard) {writeLogToSdCard(LogType.warn, tag, msg);}}public static KyLog getLog() {return log;}public static void setLog(KyLog log) {KyLog.log = log;}/*** * 设置日志文件的名称，日志文件的名称按照日期来设置，如2015-12-29 *  * @return 日志文件的名称 */private static String setLogFileName() {SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd");return dateFormat.format(new Date()) + ".txt";}/*** * 写日志到 *  * @param logType * @param tag * @param msg */private static void writeLogToSdCard(LogType logType, String tag, String msg) {String dir = "";if (logType.equals(LogType.debug)) {dir = DebugDir + setLogFileName();} else if (logType.equals(LogType.error)) {dir = ErrorDir + setLogFileName();} else if (logType.equals(LogType.info)) {dir = InfoDir + setLogFileName();} else if (logType.equals(LogType.verbose)) {dir = VerboseDir + setLogFileName();} else if (logType.equals(LogType.warn)) {dir = WarnDir + setLogFileName();}File file = new File(dir);if (!file.exists()) {try {file.createNewFile();} catch (IOException e) {e.printStackTrace();}}writeLogMsg(file, tag, msg);}/** * 按照固定格式设置日志内容 *  * @param tag * @param msg * @return */private static String setLogContent(String tag, String msg) {SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd HH-mm-ss");String time = dateFormat.format(new Date());return time + " " + tag + " " + msg + "\n";}/*** * 写日志信息 *  * @param file * @param tag * @param msg */private static void writeLogMsg(File file, String tag, String msg) {FileWriter fileWriter = null;BufferedWriter bufferedWriter = null;try {fileWriter = new FileWriter(file, true);bufferedWriter = new BufferedWriter(fileWriter);bufferedWriter.write(setLogContent(tag, msg));bufferedWriter.flush();bufferedWriter.close();fileWriter.close();} catch (IOException e) {try {bufferedWriter.close();fileWriter.close();} catch (IOException e1) {e1.printStackTrace();}e.printStackTrace();}}/*** * 清理日志文件夹 */public static void clearLogDir() {// TODO:待完成}}</span>
