动态填充的Andr​​oid微调 [英] Populate android spinner dynamically

问题描述

我在像下面的code的Andr​​oid创造了一个文本视图：

I have created a Text View in android like the code below:

 LinearLayout ll = new LinearLayout(this);
        ll.setOrientation(LinearLayout.VERTICAL);
        sv.addView(ll);

txtv = new TextView(this);
txtv.setText("text");
ll.addView(txtv);     

我创建了一个微调相同的：

Same way I have created a spinner:

spinner = new Spinner(this);
ll.addView(spinner);

但我不能就微调填充值。大多数教程给人填充微调与阵列适配器，但是它正在XML的ID，如R.id. ....因为我创建动态我不能做这样的方式。如何动态填充微调？

But I am unable to populate value on the spinner. Most tutorials giving populating spinner with array adapter but it is taking id of xml, like R.id. .... Since I am creating dynamic I cant do like that way. How can I populate spinner dynamically?

推荐答案

您需要创建SpinnerAdapter或BaseAdapter的impementation并将它设置为微调的适配器。

You need to create an impementation of SpinnerAdapter or BaseAdapter and set it as the adapter of the Spinner.

您可以通过从数组适配器返回的意见。

You return the views through the adapter from the array.

也请考虑重新命名变量。他们不是非常的描述和命名变量11做法不好。

Also please consider renaming your variables. They aren't very descriptive and naming a variable 11 is poor practice.
