LogUtil日志工具

两种方式

一

public class LogUtils {    public static final boolean DEBUG = true;    public static void e(Object o) {        if (DEBUG)            Log.e("TAG", "打印：------      " + o.toString());    }    public static void e(String o) {        if (DEBUG)            Log.e("TAG", "打印：------      " + o.toString());    }    public static void e(int i) {        if (DEBUG)            Log.e("TAG", "打印：------      " + i);    }    public static void e(float i) {        if (DEBUG)            Log.e("TAG", "打印：------      " + i);    }    public static void e(boolean b) {        if (DEBUG)            Log.e("TAG", "打印：------      " + b);    }}

二

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 msg) {        if (LEVEL <= VERBOSE) {            Log.v("---------TAG---------", msg);        }    }    public static void d(String msg) {        if (LEVEL <= DEBUG) {            Log.d("---------TAG---------", msg);        }    }    public static void i(String msg) {        if (LEVEL <= INFO) {            Log.i("---------TAG---------", msg);        }    }    public static void w(String msg) {        if (LEVEL <= WARN) {            Log.w("---------TAG---------", msg);        }    }    public static void e(String msg) {        if (LEVEL <= ERROR) {            Log.e("---------TAG---------", msg);        }    }}

只有当LEVEL 常量的值小于或等于对应日志级别值的时候，才会将日志打印出来

当LEVEL=1时，5个打印都调用；LEVEL=2时，调用前4个打印方法；为5时调用最后一个e方法；LEVEL=6时都不调用。

LEVEL为哪个级别就打印对应级别及以上的日志
