android 日志打印器 LogUtil

ndroid日志打印中需要频繁定义日志的TAG 日志内容不能输出函数名以及行数
定义了一个基于这个需求的日志辅助类

import java.text.SimpleDateFormat;import java.util.Date;import android.util.Log;public class LogUtil {    private static final boolean DEBUG = true;    public static void d(String TAG, String method, String msg) {        Log.d(TAG, "[" + method + "]" + msg);    }    public static void d(String TAG, String msg){        if (DEBUG) {            Log.d(TAG, "[" + getFileLineMethod() + "]" + msg);        }    }    public static void d(String msg){        if (DEBUG) {            Log.d(_FILE_(), "[" + getLineMethod() + "]" + msg);        }    }    public static void e(String msg){        if (DEBUG) {            Log.e(_FILE_(), getLineMethod() + msg);        }    }    public static void e(String TAG, String msg){        if (DEBUG) {            Log.e(TAG, getLineMethod() + msg);        }    }    public static String getFileLineMethod() {        StackTraceElement traceElement = ((new Exception()).getStackTrace())[2];        StringBuffer toStringBuffer = new StringBuffer("[")                .append(traceElement.getFileName()).append(" | ")                .append(traceElement.getLineNumber()).append(" | ")                .append(traceElement.getMethodName()).append("]");        return toStringBuffer.toString();    }    public static String getLineMethod() {        StackTraceElement traceElement = ((new Exception()).getStackTrace())[2];        StringBuffer toStringBuffer = new StringBuffer("[")                .append(traceElement.getLineNumber()).append(" | ")                .append(traceElement.getMethodName()).append("]");        return toStringBuffer.toString();    }    public static String _FILE_() {        StackTraceElement traceElement = ((new Exception()).getStackTrace())[2];        return traceElement.getFileName();    }    public static String _FUNC_() {        StackTraceElement traceElement = ((new Exception()).getStackTrace())[1];        return traceElement.getMethodName();    }    public static int _LINE_() {        StackTraceElement traceElement = ((new Exception()).getStackTrace())[1];        return traceElement.getLineNumber();    }    public static String _TIME_() {        Date now = new Date();        SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSS");        return sdf.format(now);    }}
