Android-java Log封装,目前感觉最适合自己的LogUtils

Posted 2022-12-03 peak wang

    封装的这个Log可以直接在日志中显示调用侧的类名，方法名，行号，方便定位问题。     

    这是好久前写的了,StackTrace数组中各元素的的含义忘了,也没必要翻书或重跑程序的必要，只记得返回下标为2的元素时指向的是调用侧,下标为1时指向的是Logg.

StackTraceElement ste = new Throwable().getStackTrace()[2];

日志如下:

 

代码：

package com.android.music.utils;

import android.util.Log;

public class Logg 

    public static String tagPrefix = "StmMusicPlayer";
    public static boolean isDebug = SystemProperties.getBoolean("persist.sys.apk.debug",true); /**persist.sys.apk.debug**/

    private static String tag() 
        StackTraceElement ste = new Throwable().getStackTrace()[2];
        String clsName = ste.getClassName();
        clsName = clsName.substring(clsName.lastIndexOf(".") + 1 ,clsName.length());

        String tag = String.format("%s|cls:%s|method:%s|line:%s|",tagPrefix,clsName,ste.getMethodName(),ste.getLineNumber());
        return tag;

    


    public static void v(String msg) 
        if (isDebug) 
            Log.v(tag(), msg);

        

    

    public static void v(String msg, Throwable tr) 
        if (isDebug) 
            Log.v(tag(), msg, tr);

        

    

    public static void d(String msg) 
        if (isDebug) 
            Log.d(tag(), msg);

        

    

    public static void d(String msg, Throwable tr) 
        if (isDebug) 
            Log.d(tag(), msg, tr);

        

    

    public static void i(String msg) 
        if (isDebug) 
            Log.i(tag(), msg);

        

    

    public static void i(String msg, Throwable tr) 
        if (isDebug) 
            Log.i(tag(), msg, tr);

        

    

    public static void w(String msg) 
        if (isDebug) 
            Log.w(tag(), msg);

        

    

    public static void w(String msg, Throwable tr) 
        if (isDebug) 
            Log.w(tag(), msg, tr);

        

    

    public static void e(String msg) 
        if (isDebug) 
            Log.e(tag(), msg);

        

    

    public static void e(String msg, Throwable tr) 
        if (isDebug) 
            Log.e(tag(), msg, tr);

        

    

    public static void showLog(String tag, String msg) 
        if (isDebug) 
            Log.i(tag, msg);
