I want to execute a sqlite query:
我想执行一个sqlite查询:
select * from table_name where id in (23,343,33,55,43);
The values in the in clause need to be taken from an array of strings:
in子句中的值需要从字符串数组中获取:
String values[] = {"23","343","33","55","43"}
How can I achieve that?
我怎样才能做到这一点?

I believe a simple toString()
will mostly do the trick:
我相信一个简单的toString()将主要做的伎俩:
String values[] = {"23","343","33","55","43"};
String inClause = values.toString();
//at this point inClause will look like "[23,343,33,55,43]"
//replace the brackets with parentheses
inClause = inClause.replace("[","(");
inClause = inClause.replace("]",")");
//now inClause will look like "(23,343,33,55,43)" so use it to construct your SELECT
String select = "select * from table_name where id in " + inClause;
