检测用户输入忽略大小写

比较txtOrigin和txtDestination 的值,查询变量，假设他们匹配。

           if((origin.getText().toString().matches(queryOrigin))
                    && (destination.getText().toString().matches(queryDestination)))
            {
            //proceed to route found layout
                Intent openRouteFound = new Intent("com.icommute.feu.RouteFound");
                startActivity(openRouteFound);
            }

        /**compares the values of txtOrigin 
        and txtDestination to the query 
        variables assuming it doesn't match*/
            else
            {
            //proceed to no routes found layout
                Intent openNoRoute = new Intent("com.icommute.feu.NoRoute");
                startActivity(openNoRoute);
            }

使用String.equalsIgnoreCase()放法忽略大小写
