我想比较从我的表单到查询数据的用户输入。但我希望它不要区分大小写。我怎么做？

Question

/* txtOrigin 和txtDestination的值进行比较，以查询 变量假设它匹配/

   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

试试这个

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

这将使正则表达式CASE_INSENSITIVE

Answer 3

使用.equalsIgnoreCase（）方法 如：

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

}
