Question

我的资源中有一个数组，我希望在ListView中显示，但我失败了，所以也许有人能说出我做错了什么，我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？这就是我填写列表中每一行的方式。

Answer 1

你试过了吗？

holder.populateFrom(Estados[position]);

<强>加成

这是：

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

原定于：

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

从ListView中的xml资源显示数组不起作用
