java - 使条件忽略大写锁定？

Question

如何让条件忽略大写锁定？我想改变:

if ( Name.contains ( layout.txtName.getText ().toString () ) )

并让它忽略大写字母。

case R.id.Contane:
            if (Name.contains(layout.txtName.getText().toString()))
            {
                AlertDialog.Builder alert = new AlertDialog.Builder(MainActivity.this);

                alert.setTitle("this is the first resulet for the name that you typed");

                alert.setMessage("The contact "+Name+" was found in this phone... yaah");

                alert.setPositiveButton("ok",new DialogInterface.OnClickListener() {

                    @Override

                    public void onClick(DialogInterface dialogInterface, int i)
                    {


                    }

                });
                alert.show();
                Found = true;
                break;

Answer 1

尝试toLowerCase()

if ( Name.toLowerCase().contains ( layout.txtName.getText ().toString ().toLowerCase()))

示例:

if("Abc".toLowerCase().contains("a".toLowerCase()))
    System.out.print("Success");

输出:

Success
