我正在尝试在选项卡式视图中的选项卡下显示自定义列表。 我的代码在这里：

super(context, textViewResourceId, items);
this.items = items;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View v = convertView;
if (v == null) {
LayoutInflater vi = (LayoutInflater)getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v = vi.inflate(R.layout.app_row, null);
}
App app = items.get(position);
if (app != null) {
TextView tt = (TextView) v.findViewById(R.id.toptext);
TextView bt = (TextView) v.findViewById(R.id.bottomtext);
if (tt != null) {
tt.setText("Name: "+app.getAppName()); }
if(bt != null){
bt.setText("Status: "+ app.getAppDesc());
}
}
return v;
}
}
但是列表的结果是： 我看不到整个列表，它以某种方式停止显示列表的其余部分。 请帮忙！ 谢谢，布什
