Android Check Box可见性问题？

Question

在我的应用程序中，我有两个复选框，一个是 PayByCredit ，还有一个是 PaybySMS 两个复选框都不可见问题是什么？为了显示复选框，我给出了像android:visibility="visible"这样的代码，但仍然没有用。请问有人可以帮我解决这个问题吗？

我的XML代码是：

请帮我解决这个问题??

Answer 1

在你的代码中试试这个：

paybycard.setVisibility(0);
paybysms.setVisibility(0);

希望得到这个帮助，谢谢

Answer 2

删除android:background="@null"

Answer 3

这些布局对我有用：

<CheckBox
    android:id="@+id/paysms"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginTop="16dp"
    android:background="@null"
    android:visibility="visible"
    android:text="pay with sms"
    android:layout_marginLeft="10dp"
    android:textColor="#000000" />
<CheckBox
    android:id="@+id/paycredit"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_below="@id/paysms"
    android:background="@null"
    android:text="pay credit"
    android:visibility="visible"
    android:layout_marginLeft="10dp"
    android:textColor="#000000" />
