关于android Log的isLoggable定义
作者:互联网
什么是isLoggable?
isLoggable是android.util.Log提供的方法,用于检查指定Log的TAG的level是否满足打印条件,如满足则返回true反之则返回false。
源码中关于isLoggable的注释
isLoggable在源码中的注释如下:
/**
* Checks to see whether or not a log for the specified tag is loggable at the specified level.
*
* The default level of any tag is set to INFO. This means that any level above and including
* INFO will be logged. Before you make any calls to a logging method you should check to see
* if your tag should be logged. You can change the default level by setting a system property:
* 'setprop log.tag.<YOUR_LOG_TAG> <LEVEL>'
* Where level is either VERBOSE, DEBUG, INFO, WARN, ERROR, ASSERT, or SUPPRESS. SUPPRESS will
* turn off all logging for your tag. You can also create a local.prop file that with the
* following in it:
* 'log.tag.<YOUR_LOG_TAG>=<LEVEL>'
* and place that in /data/local.prop.
*
* @param tag The tag to check.
* @param level The level to check.
* @return Whether or not that this is allowed to be logged.
* @throws IllegalArgumentException is thrown if the tag.length() > 23.
*/
public static native boolean isLoggable(String tag, int level);
使用注意
-
isLoggable默认level为android.util.Log.INFO;
-
只有 level >= INFO才能输出,即level >= INFO时isLoggable返回true,反之则返回false;
