在 ListView 中显示来自 xml 资源的数组不起作用

Question

我的资源中有一个数组，我想在 ListView 中显示，但我失败得很惨，所以也许有人可以告诉我我做错了什么以及我应该怎么做才能做到这一点。这是我使用的代码：

在我的 XML 资源中：

<?xml version="1.0" encoding="utf-8"?>
<resources>
<string name="app_name">myApp</string>
<string-array name="EstadosArray">
    <item >Estado1</item>
    <item >Estado2</item>
    <item >Estado3</item>
    <item >Estado4</item>
    <item >Estado5</item>
    <item >Estado6</item>        
</string-array>
</resources>

在我的活动中：

public class myMain extends Activity{
String[] Estados;
eAdapter ea=null;
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
            setContentView(R.layout.main);

    Estados = getResources().getStringArray(R.array.EstadosArray);
    ea = new eAdapter();
    ListView EstadosList = (ListView) findViewById(R.id.estadosList);
    EstadosList.setAdapter(ea);

}

class eAdapter extends ArrayAdapter<String> {
    eAdapter() {
            super(myMain.this, android.R.layout.simple_list_item_1, Estados);
            }
    public View getView(int position, View convertView, ViewGroup parent) {
        eHolder holder;
        if (convertView == null) {
            LayoutInflater inflater = getLayoutInflater();
            convertView = inflater.inflate(R.layout.esatdoitem, null);
            holder = new eHolder(convertView);
            convertView.setTag(holder);
        } else {
            holder = (eHolder) convertView.getTag();
        }
        holder.populateFrom(Estados.get(position));  // HERE IS WHERE I HAVE THE issue is, I DON'T KNOW HOW TO GET THE POSITION, IS GIVING ME AN ERROR (CANNOT INVOKE GET(INT) ON THE ARRAY TYPE STRING[])
        return (convertView);
    }

}
class eHolder{
    public TextView esname=null;
    eHolder(View row) {
        esname = (TextView) row.findViewById(R.id.ename);
    }
    void populateFrom(String est) {
        esname.setText(est);
    }
}

我知道问题是因为 string[] 不是 int 但我该如何解决？这就是我将如何填充列表的每一行。

Answer 1

你试过了吗：

holder.populateFrom(Estados[position]);

加法

这是：

    esname = (TextView) row.findViewById(R.id.ename);

应该是：

    esname = (TextView) row.findViewById(R.id.esname);
