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); } }
