超级好用的Android日志工具类

import android.util.Log;public class LogUtil {private static boolean DEBUG = true;private static String tag = "[app]";private String mClassName;private static LogUtil log;private static final String USER_NAME = "@user@";private LogUtil(String name) {mClassName = name;}/** * Get The Current Function Name *  * @return Name */private String getFunctionName() {StackTraceElement[] sts = Thread.currentThread().getStackTrace();if (sts == null) {return null;}for (StackTraceElement st : sts) {if (st.isNativeMethod()) {continue;}if (st.getClassName().equals(Thread.class.getName())) {continue;}if (st.getClassName().equals(this.getClass().getName())) {continue;}return mClassName + "[ " + Thread.currentThread().getName() + ": "+ st.getFileName() + ":" + st.getLineNumber() + " "+ st.getMethodName() + " ]";}return null;}public static void i(Object str) {print(Log.INFO, str);}public static void d(Object str) {print(Log.DEBUG, str);}public static void v(Object str) {print(Log.VERBOSE, str);}public static void w(Object str) {print(Log.WARN, str);}public static void e(Object str) {print(Log.ERROR, str);}private static void print(int index, Object str) {if (!DEBUG) {return;}if (log == null) {log = new LogUtil(USER_NAME);} String name = log.getFunctionName();if (name != null) {str = name + " - " + str;}switch (index) {case Log.VERBOSE:Log.v(tag, str.toString());break;case Log.DEBUG:Log.d(tag, str.toString());break;case Log.INFO:Log.i(tag, str.toString());break;case Log.WARN:Log.w(tag, str.toString());break;case Log.ERROR:Log.e(tag, str.toString());break;default:break;}}}

直接作为工具类使用 调用非常方便 默认是debug模式。发布时候 直接把变量DEBUG改成false就ok  也可以方便把不同测试等级与debug 联动

LogUtil.i("测=i====count= "+count++);
LogUtil.e("测=e====count= "+count++);
