之前项目中,需要自己打印log,于是模仿别人的工具,整理了一个日志打印工具,支持开关、打印文件名、方法名、行数等:

package com.xinwei.palmhall.util;  

import java.text.SimpleDateFormat;  
import java.util.Date;  

import android.util.Log;  

public class LogCatUtil {  
private static final boolean DEBUG = true;  

public static void d(String TAG, String method, String msg) {  
    if (DEBUG) {  
        Log.d(TAG, "[" + method + "]" + msg);  
    }  
}  

public static void d(String TAG, String msg) {  
    if (DEBUG) {  
        Log.d(TAG, "[" + getFileLineMethod() + "]" + msg);  
    }  
}  

public static void e(String TAG, String method, String msg) {  
    if (DEBUG) {  
        Log.e(TAG, "[" + method + "]" + msg);  
    }  
}  

public static void e(String TAG, String msg) {  
    if (DEBUG) {  
        Log.e(TAG, "[" + getFileLineMethod() + "]" + msg);  
    }  
}  

public static void i(String TAG, String method, String msg) {  
    if (DEBUG) {  
        Log.i(TAG, "[" + method + "]" + msg);  
    }  
}  

public static void i(String TAG, String msg) {  
    if (DEBUG) {  
        Log.i(TAG, "[" + getFileLineMethod() + "]" + msg);  
    }  
}  

public static void w(String TAG, String method, String msg) {  
    if (DEBUG) {  
        Log.w(TAG, "[" + method + "]" + msg);  
    }  
}  

public static void w(String TAG, String msg) {  
    if (DEBUG) {  
        Log.w(TAG, "[" + getFileLineMethod() + "]" + msg);  
    }  
}  

// 获取文件、行数  
private 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();  
}  

// 获取行数  
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();  
}  

// 获取文件名  
public static String _FILE_() {  
    StackTraceElement traceElement = ((new Exception()).getStackTrace())[2];  
    return traceElement.getFileName();  
}  

// 获取方法名  
public static String _FUNC_() {  
    StackTraceElement traceElement = ((new Exception()).getStackTrace())[1];  
    return traceElement.getMethodName();  
}  

// 获取行数  
public static int _LINE_() {  
    StackTraceElement traceElement = ((new Exception()).getStackTrace())[1];  
    return traceElement.getLineNumber();  
}  

// 获取时间  
public static String _TIME_() {  
    Date now = new Date();  
    SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSS");  
    return sdf.format(now);  
}  
}
