android - 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

/*将 txtOrigin 和 txtDestination 的值与查询变量进行比较，假设它匹配/

                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);
                }

Answer 1

请尝试：

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

Answer 2

使用 .equalsIgnoreCase() 方法，例如：

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

}

Answer 3

试试这个

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

这将使正则表达式CASE_INSENSITIVE
