关于Android中log日志（LogUtil）的封装

为了便于开发，特此封装了一个日志工具类，可以具体到类名，方法名，行数；

代码如下：

public enum LogUtil {
    INSTANCE;

    private final static boolean all = true;

    private final static boolean i = true;

    private final static boolean e = true;

    private final static boolean d = true;

    private static String className;

    private static String methodName;

    private static int lineName;

    private final static String TAG = LogUtil.class.getSimpleName();



    public void i(String msg){
        if(all && i){
            getName(new Throwable().getStackTrace());
            Log.i(TAG, createLog(msg));
        }
    }

    public void e (String msg){
        if(all && e){
            getName(new Throwable().getStackTrace());
            Log.e(TAG, createLog(msg) );
        }
    }

    public void d (String msg){
        if(all && d){
            getName(new Throwable().getStackTrace());
            Log.d(TAG, createLog(msg));
        }
    }


    private static void getName(StackTraceElement []stackTraceElements){
        className = stackTraceElements[1].getClassName();
        methodName = stackTraceElements[1].getMethodName();
        lineName = stackTraceElements[1].getLineNumber();
    }

    private static String createLog(String msg){
        StringBuilder sb = new StringBuilder();
        return sb.append(className).append(methodName).append(lineName).append(":").append(msg).toString();
    }

}

效果：
