推荐答案

要从微调删除特定的项目，你必须从arrayadapter这是您使用的填充它删除它。

To delete particular item from spinner you have to remove it from arrayadapter which is you using for filling it.

所以首先得到你想要ř删除项目的位置。

不是获取对象FRM从mehod其位置arrayadapter。

than get the object frm arrayadapter from its position by mehod.

int pos = 0;object t=m_adapterForSpinner.getitem(pos);//whr m_arrayadapter is array adapter using for filling spinner

---

和比微调用以下code删除：

---

and than remove it from spinner by using following code:

m_adapterForSpinner.remove((CharSequence) t);

---

比arrayadapter再次填写乌尔微调。

---

than fill ur spinner again with arrayadapter.
