What is wrong in the following soql query?

id i = 0037F00000M6MCHQA3;
String fieldNames='name,id';
String objName = 'contact';
String queryStr = 'SELECT ' + fieldNames + ' FROM ' + objName + ' WHERE id IN :(\'i\')';
System.debug(queryStr);

Hi Alain, 
The result of your query is SELECT name,id FROM contact WHERE id IN :('0037F00000M6MCHQA3'), but i want to display the seleceted records.

The colon is useless here : 
Id i = '0037F00000M6MCHQA3';
String fieldNames='name,id';
String objName = 'contact';
String queryStr = 'SELECT ' + fieldNames + ' FROM ' + objName + ' WHERE id IN (\'' + i + '\')';
System.debug(queryStr);
