遍历hashmap的三种方式_hashmap循环遍历

private HashMap<String,RadioButton> channels=new HashMap<>();
    private void selectPayChannle(String paychannel) {
        for (Map.Entry<String,RadioButton> entry:channels.entrySet()){

            payChannel = paychannel;
            RadioButton rb = entry.getValue();
            if(entry.getKey().equals(paychannel)){

                boolean isCheck = rb.isChecked();
                rb.setChecked(!isCheck);

            }
            else
                rb.setChecked(false);
        }
    }
