填充微调凭借多年在动态的Andr​​oid？ [英] Populate spinner with years dynamically in Android?

问题描述

我一直在货架我的大脑试图得到这个工作。我想动态多年来从1900年进入到本年度变成微调。我不认为这是可能的使用XML定义的数组做的，但我可以做一个数组适配器？这是我到目前为止有：

I have been racking my brain trying to get this to work. I want to dynamically enter in years from 1900 to the current year into a spinner. I don't think that this is possible to do using an XML defined array but can I do it with an array adapter? Here is what I have so far:

ArrayList<String> years = new ArrayList<String>();
int thisYear = Calendar.getInstance().get(Calendar.YEAR);

for (int i = 1900; i <= thisYear; i++) 
{
    years.add(i);
}

adapter = new ArrayAdapter<String>(this, 
           android.R.layout.simple_spinner_item, years);

//spinner to enter this list to
spinYear = (Spinner)findViewById(R.id.yearspin);

下面是XML的微调：

Here's the XML for the spinner:

<Spinner
        android:id="@+id/yearspin"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"/>

感谢您的帮助。

Thanks for any help.

推荐答案

您是非常密切的。试试这个：

You're very close. Try this:

ArrayList<String> years = new ArrayList<String>();
int thisYear = Calendar.getInstance().get(Calendar.YEAR);
for (int i = 1900; i <= thisYear; i++) {
    years.add(Integer.toString(i));
}
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, years);

Spinner spinYear = (Spinner)findViewById(R.id.yearspin);
spinYear.setAdapter(adapter);

您刚才忘了补充

spinYear.setAdapter(adapter);
