android - 使用字符串数组填充 Spinner

Question

我正在尝试在我的 Android 应用程序上使用数组适配器使用字符串数组填充微调器。该代码对我来说似乎很合理，因此我向 SO 的精彩社区询问。

这是我的填充函数:

private void populateSpinners(String intentMessage)
{
//initialize variables and get spinners, resources
Resources res = getResources();
String[] types = null;
Spinner iHaveSpinner = (Spinner) findViewById(R.id.iHaveSpinner);
Spinner iWantSpinner = (Spinner) findViewById(R.id.iWantSpinner);

//grab appropriate array for unit types
if(intentMessage.equalsIgnoreCase("Force"))
    types = res.getStringArray(R.array.ForceArray);

//initialize adapter and populate spinners
ArrayAdapter<String> typeAdapter = new ArrayAdapter<String>(this,R.id.iHaveSpinner,types);
iHaveSpinner.setAdapter(typeAdapter);
iWantSpinner.setAdapter(typeAdapter);
}

和我的 logcat:

我的问题是我似乎找不到对我的代码的任何引用(希望我就在那里，说到我的阅读能力......)，而且我对 Android 还很陌生，所以我不是最擅长捕获其他运行时错误。

非常感谢!!!

资源 ID #0x7f090003 类型 #0x12 无效

出现该异常消息的原因是您向ArrayAdapter 构造函数提供了一个view id，而它需要一个layout id .您可以从作为堆栈跟踪一部分的 getLayout(...) 调用中看出，但可以通过正确阅读 documentation for the invoked constructor 轻松避免这种情况。 :

public ArrayAdapter (Context context, int resource, T[] objects)

Parameters
context The current context.
resource The resource ID for a layout file containing a TextView to use when instantiating views.
objects The objects to represent in the ListView.
