最理想的情况是能够控制日志的打印,当程序处于开发阶段就让日志打印出来,当程序上线之后就把日志屏蔽掉。

例如打印一行WARN级别的日志就可以写成这样:

LogUtil.w("TAG", "warn log");

我们只需要修改LEVEL常量的值,就可以自由的控制打印日志的行为了。

package com.zhangbz.pals.util;

import android.util.Log;

public class LogUtil {
    
    public static final int VERBOSE = 1;
    
    public static final int DEBUG = 2;
    
    public static final int INFO = 3;
    
    public static final int WARN = 4;
    
    public static final int ERROR = 5;
    
    public static final int NOTHING = 6;
    
    public static final int LEVEL = VERBOSE;
    
    public static void v(String tag, String msg) {
        if (LEVEL <= VERBOSE) {
            Log.v(tag, msg);
        }
    }
    
    public static void d(String tag, String msg) {
        if (LEVEL <= DEBUG) {
            Log.d(tag, msg);
        }
    }
    
    public static void i(String tag, String msg) {
        if (LEVEL <= INFO) {
            Log.i(tag, msg);
        }
    }
    
    public static void w(String tag, String msg) {
        if (LEVEL <= WARN) {
            Log.w(tag, msg);
        }
    }
    
    public static void e(String tag, String msg) {
        if (LEVEL <= ERROR) {
            Log.e(tag, msg);
        }
    }
