Answer 1

if(etConfirmPassword.getText().toString().equals(etPassword.getText().toString()))
{
    //Password Match
}
else
{

}

如果需要，您可以在字符串上使用 .trim()。

.equalsIgnoreCase()忽略字符串的大小写敏感度，.equals()在编译两个字符串时考虑字符大小写敏感度

Answer 2

public boolean isPasswordMatching(String new1, String conform1) 
{
       if(new1.equals(conform1))
       {
           return true;
       }
       Toast.makeText(MainActivity.this,"Passwords does not match", Toast.LENGTH_SHORT).show();
       return false;
}

如果您不希望密码区分大小写，请在存储时将密码转换为小写或大写。
