Android Log日志规则打印

阳光穿透心脏的1/2处 2022-08-21 05:40 248阅读 0赞

现有好多项目日志太乱。发布的版本日志依据存在。通篇的sysotem.out.print
    
    现有日志类特点
     
    /**
     * Log工具，类似android.util.Log。 tag自动产生，格式:
     * customTagPrefix:className.methodName(L:lineNumber),
     * customTagPrefix为空时只输出：className.methodName(L:lineNumber)。
     * 
     */
    
    可以准确的定位到类。哪一行输出的日志
    logutilConfig 控制是否打印日志

1、LogUtil

public class LogUtil {
    
    	public static String customTagPrefix = "Sunday";
    
    	private LogUtil() {
    	}
    
    	private static String generateTag() {
    		StackTraceElement caller = new Throwable().getStackTrace()[2];
    		String tag = "%s.%s(L:%d)";
    		String callerClazzName = caller.getClassName();
    		callerClazzName = callerClazzName.substring(callerClazzName
    				.lastIndexOf(".") + 1);
    		tag = String.format(tag, callerClazzName, caller.getMethodName(),
    				caller.getLineNumber());
    		tag = TextUtils.isEmpty(customTagPrefix) ? tag : customTagPrefix + ":"
    				+ tag;
    		return tag;
    	}
    
    	public static void d(String content) {
    		if (!LogConfig.isDebug)
    			return;
    		String tag = generateTag();
    
    		Log.d(tag, content);
    	}
    
    	public static void d(String content, Throwable tr) {
    		if (!LogConfig.isDebug)
    			return;
    		String tag = generateTag();
    
    		Log.d(tag, content, tr);
    	}
    
    	public static void e(String content) {
    		if (!LogConfig.isDebug)
    			return;
    		String tag = generateTag();
    
    		Log.e(tag, content);
    	}
    
    	public static void e(String content, Throwable tr) {
    		if (!LogConfig.isDebug)
    			return;
    		String tag = generateTag();
    
    		Log.e(tag, content, tr);
    	}
    
    	public static void i(String content) {
    		if (!LogConfig.isDebug)
    			return;
    		String tag = generateTag();
    
    		Log.i(tag, content);
    	}
    
    	public static void i(String content, Throwable tr) {
    		if (!LogConfig.isDebug)
    			return;
    		String tag = generateTag();
    
    		Log.i(tag, content, tr);
    	}
    
    	public static void v(String content) {
    		if (!LogConfig.isDebug)
    			return;
    		String tag = generateTag();
    
    		Log.v(tag, content);
    	}
    
    	public static void v(String content, Throwable tr) {
    		if (!LogConfig.isDebug)
    			return;
    		String tag = generateTag();
    
    		Log.v(tag, content, tr);
    	}
    
    	public static void w(String content) {
    		if (!LogConfig.isDebug)
    			return;
    		String tag = generateTag();
    
    		Log.w(tag, content);
    	}
    
    	public static void w(String content, Throwable tr) {
    		if (!LogConfig.isDebug)
    			return;
    		String tag = generateTag();
    
    		Log.w(tag, content, tr);
    	}
    
    	public static void w(Throwable tr) {
    		if (!LogConfig.isDebug)
    			return;
    		String tag = generateTag();
    
    		Log.w(tag, tr);
    	}
    
    	public static void wtf(String content) {
    		if (!LogConfig.isDebug)
    			return;
    		String tag = generateTag();
    
    		Log.wtf(tag, content);
    	}
    
    	public static void wtf(String content, Throwable tr) {
    		if (!LogConfig.isDebug)
    			return;
    		String tag = generateTag();
    
    		Log.wtf(tag, content, tr);
    	}
    
    	public static void wtf(Throwable tr) {
    		if (!LogConfig.isDebug)
    			return;
    		String tag = generateTag();
    
    		Log.wtf(tag, tr);
    	}
    
    }

2、LogConfig（主要配置LogUtil是否输出日志）

public class LogConfig {
    
    	public static boolean isDebug = true;
    }
