android - 显示空行的自定义 ListView

Question

我的自定义 ListView 显示空行，但是当我使用 logcat 显示数据时，它显示数据都在我的数组列表中...如何让 ListView 显示我的数组列表项？

public class Myarrayadapter extends ArrayAdapter<String> {

Context context;
ArrayList<String> values;
int resid;

public Myarrayadapter(Context context, int resid, ArrayList<String> values) {
    super(context, resid, values);
    this.resid = resid;
    this.context = context;
    this.values = values;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    View rowView = inflater.inflate(resid, parent, false);
    return rowView;
}
}

在这里上课////////////////////////////////////////

    final ListView HomeListView = (ListView) findViewById(R.id.HomeListView);
    String[] filelist = fileList();
    ArrayList<String> fileList = new ArrayList<String>();

    for (int i=0; i < filelist.length; i++) {//displays only first half of job number
          String[] stemp = filelist[i].split("\\.");
        if(!fileList.contains(stemp[0])) {//makes sure only one job number is show in the list
            fileList.add(stemp[0]);
        }
    }
    Collections.reverse(fileList);
    Myarrayadapter listAdapter = new Myarrayadapter(this, R.layout.homelistview, fileList);
    HomeListView.setAdapter(listAdapter);
    HomeListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
            //get the clicked items job no. and pass it to the next activity which will display all relevant jobs
            Intent detailedlist_intent = new Intent(Home.this, Home2.class);
            detailedlist_intent.putExtra("Jobno", HomeListView.getItemAtPosition(position).toString());
            startActivity(detailedlist_intent);
        }
    });

您应该将值设置为 resid 布局内的 textview。您没有将文本设置为 TextView 。这就是为什么它空空如也。
