java:spinner ownerdraw不关闭下拉列表

我正在写一个android java应用程序，我不得不写一个颜色选择器，然后我选择微调器解决方案。我准备了两个布局，一个用于微调器，另一个用于下拉列表。因为我需要根据选择修改布局的外观，所以我必须自定义arrayadapter类来管理下拉列表的设计。

public class CColorPicker<T extends Integer> extends ArrayAdapter implements SpinnerAdapter {

我必须说，一切似乎工作，它不会给问题，它画得很完美（虽然我还没有完善的图形方面），甚至点击被截获没有问题。。。。但是，我有一个问题，我一直无法解决。关闭下拉列表。

其行为应该是，如果我'点击'的颜色，它被选中，并关闭下拉列表，否则按下按钮旁边的颜色，它打开了颜色对话框，下拉列表不关闭，当你退出颜色对话框，在列表中的颜色被替换为所选的一个。

因此，在做了各种尝试之后，我决定自己编写所有内容，并定制了一个从“linearlayout”派生的控件，因此我管理了单击并直接打开“颜色”对话框。然而，我不能忍受不知道解决方案是否存在，而且我还没有找到它。显然，我可以定制spinner类，但这将是一项艰巨的工作，而且在任何情况下，结果都将与获得的结果相似。
所以，这里有两个问题，第一个当然是“如何关闭下拉列表？”显然，我已经尝试过“setpressed”和“clearfocus”两种方法，但它们都不起作用。。我仍然可以说'点击'外的下拉关闭，所以问题是程序或我的一部分的错误。。。你知道吗？以下是消息来源。

第二个问题是：有没有办法把下拉列表放在微调器的下边缘而不是上边缘？
感谢任何能给我帮助或答案的人。我为我糟糕的英语道歉。。。
