我想将表单中的用户输入与查询的数据进行比较。 但我希望它不区分大小写。 我怎么做？

Question

/* compares the values of txtOrigin and txtDestination to the query variables assuming it matches /

                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);
                }

Answer 1

Please try that:

 if((origin.getText().toString().equalsIgnoreCase(queryOrigin))
      && (destination.getText().toString().equalsIgnoreCase(queryDestination)))
 {
    ...
 }

Answer 2

use .equalsIgnoreCase() method eg:

if((origin.getText().toString().equalsIgnoreCase(queryOrigin))
                    && (destination.getText().toString().equalsIgnoreCase(queryDestination)))
            {

}

Answer 3

Try this

origin.getText().toString().matches("(?i)" + queryOrigin) .

This will make regex CASE_INSENSITIVE
