public class LogUtil {

private static final String TAG = "print";

/*打印*/
public static void print(String msg) {
//非Debug版本，则不打印日志
if (false) {
return;
        }
        String tmp = getLineFile() + getLineMethod() + msg;
        Log.i(TAG, tmp);
    }

/*打印*/
public static void print(String tag,String msg) {
//非Debug版本，则不打印日志
if (false) {
return;
        }
        String tmp = getLineFile() + getLineMethod() + msg;
        Log.i(tag, tmp);
    }

/*获取行所在的行号和方法名*/
public static String getLineMethod() {
        StackTraceElement traceElement = ((new Exception()).getStackTrace())[2];
        StringBuffer toStringBuffer = new StringBuffer("[")
                .append(traceElement.getLineNumber()).append(" | ")
                .append(traceElement.getMethodName()).append("]");
return toStringBuffer.toString();
    }

/*获取行所在的文件名*/
public static String getLineFile() {
        StackTraceElement traceElement = ((new Exception()).getStackTrace())[2];
return traceElement.getFileName();
    }
}
