我试图在我的Android应用程序上使用数组适配器填充带有字符串数组的微调器。代码对我来说听起来很合理,因此我在SO上询问了精彩的社区。
这是我的填充功能:
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:

我的注意事项是,我似乎无法找到任何对我的代码的引用(希望我就在那里,对我的阅读技巧说话......),而且我还是比较陌生的Android因此我不能最好地捕捉其他运行时错误。
非常感谢!!!

答案 0 :(得分:3)
Resource ID #0x7f090003 type #0x12 is not valid
该异常消息的原因是您向ArrayAdapter
构造函数提供视图ID ,而期望布局ID 。你可以从作为堆栈跟踪一部分的getLayout(...)
调用来判断,但通过正确阅读documentation for the invoked constructor可以很容易地避免它:
public ArrayAdapter (Context context, int resource, T[] objects)
参数
context
当前背景。
resource
布局文件的资源ID ,包含在实例化视图时使用的TextView。
objects
要在ListView中表示的对象。
