机器人 : customer List Adatper + ArrayList

Question

团队，

你能帮我调试这个问题吗？

ActivityAdapter activityAdapter = new ActivityAdapter(this,activityList); Log.d("列表", "列表显示 - 1");

    setListAdapter( activityAdapter );
    Log.d("List", "list done");

在setListAdapter的时候抛出异常，

类 ActivityList 扩展了 LinearLayout {

public ActivityList(Context context, ActivityBean activityBean) {
    super(context);

    this.setOrientation(HORIZONTAL);
    ListView listView = new ListView(context);
    LinearLayout.LayoutParams idParams = 
        new LinearLayout.LayoutParams(100, LayoutParams.WRAP_CONTENT);
    //cityParams.setMargins(10, 10, 10, 10);

    TextView idColumn = new TextView( context );
    idColumn.setText( activityBean.getActivityId() );
    idColumn.setTextSize(14f);
    idColumn.setTextColor(Color.WHITE);
    listView.addView( idColumn, idParams);       

    LinearLayout.LayoutParams accountNameParams = 
        new LinearLayout.LayoutParams(20, LayoutParams.WRAP_CONTENT);


    TextView accountNameView = new TextView(context);
    accountNameView.setText( activityBean.getAccountName() );
    accountNameView.setTextSize( 14f );
    accountNameView.setTextColor(Color.WHITE);
    listView.addView( accountNameView, accountNameParams);            

    LinearLayout.LayoutParams typeParams = 
        new LinearLayout.LayoutParams(25, LayoutParams.WRAP_CONTENT);

    //ImageView skyControl = new ImageView( context );
    TextView typeView = new TextView(context);
    typeView .setText( activityBean.getAccountName() );
    typeView.setTextSize( 14f );
    typeView .setTextColor(Color.WHITE);
    listView.addView( typeView, typeParams );
    addView(listView);
}

公共(public)类 ActivityAdapter 扩展 BaseAdapter{

public ActivityAdapter(Context context, List activityList) {
    this.context = context;
    this.activityList = activityList;
}

private Context context;
private List activityList;

@Override
public int getCount() {
    // TODO Auto-generated method stub
    return activityList.size();
}

@Override
public Object getItem(int arg0) {
    // TODO Auto-generated method stub
    return null;
}

@Override
public long getItemId(int position) {
    return position;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    ActivityBean activity = (ActivityBean) activityList.get(position);
    return new ActivityList(this.context, activity );

}

提前致谢

您正在使用 ListActivity，这要求您在内容 XML 中有一个 ListView，其 id 为“@id:android/list”

参见 documentation for ListActivity了解更多详情。
