我有一个主要的东西，有一个适配器来显示ListView中的每一个单项，我只得到索引位置的第一个值。
我从android中的webservice获得了一系列评论。它是一个数组内的数组。
主要的JSONArray它的“noticias”有很多预览jsonobject。现在：“评论”它是另一个阵列。
这是我的ContenidoNews.java类。我从预览Activity：
中传递了一个意图中的“comment”数组public class ContenidoNews extends YouTubeBaseActivity implements YouTubePlayer.OnInitializedListener{

到目前为止很好......现在我需要将所有这些传递给我的适配器：
public class ListAdapter extends BaseAdapter {
// Declare Variables
Context context;
LayoutInflater inflater;
private ArrayList<HashMap<String, String>> data;
private HashMap<String, String> resultp;
public ListAdapter(Context context,
ArrayList<HashMap<String, String>> d) {
this.context = context;
data = d;
}
@Override
public int getCount() {
return data.size();
}
@Override
public Object getItem(int position) {
return data.get(position);
}
@Override
public long getItemId(int position) {
return position;
}
public View getView(int position, View convertView, ViewGroup parent) {
// Declare Variables
TextView author;
TextView comment;
inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View itemView = inflater.inflate(R.layout.comment_item, parent, false);
resultp = new HashMap<String, String>();
final int pos = position;
resultp = data.get(position);
Log.e("data", data.get(position).toString());
author = (TextView) itemView.findViewById(R.id.tvauthorcomment);
author.setText(resultp.get(ContenidoNews.AUTHOR));
author.setTypeface(textofat);
comment = (TextView) itemView.findViewById(R.id.tvofcomment);
comment.setText(resultp.get(ContenidoNews.COMMENT));
comment.setTypeface(texto);
return itemView;
}
}
Log.e的结果（“data full”，data.toString（））;其：
10-08 22:33:40.564: E/data full(26463): [{comtext=Prueba, comauthor=Mariano xxxx}, {comtext=una clarísima definición, comauthor=Susana A xxxx}]
顺便说一句，在日志中打印7次......但是我有2个值。
现在......这就是Log.e（“data”，data.get（position）.toString（））;给了我：
10-08 22:21:11.444: E/data(24618): {comtext=Prueba, comauthor=Mariano xxxx}
和
author.setText(resultp.get(ContenidoNews.AUTHOR));
comment.setText(resultp.get(ContenidoNews.COMMENT));
在适配器中也只给了我listview中的第一个值（comment_item.xml）：
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<TextView
android:id="@+id/tvauthorcomment"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginTop="5dp"
android:paddingLeft="20dp"
android:text="Autor Comentario"
android:textColor="#707070"
android:textSize="20sp" />
<TextView
android:id="@+id/tvofcomment"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="10dp"
android:layout_marginTop="5dp"
android:paddingLeft="30dp"
android:paddingRight="20dp"
android:text="Contenido del comentario"
android:textColor="#707070"
android:textSize="19sp" />
<View
android:layout_width="fill_parent"
android:layout_height="1dp"
android:layout_marginLeft="20dp"
android:layout_marginRight="20dp"
android:background="#BBBBBB" />
</LinearLayout>
</LinearLayout>
我只能得到第一个值......我无法解决这个问题。我从很多小时起都没有库存。我不明白这是什么问题。请帮助！
我会提前感谢任何答案！

答案 0 :(得分：3)
我们不应该在ScrollView中使用ListView，因为列表视图已经是ScrollView，列表视图中的项目已经可以滚动了。
如果您使用，则列表视图将仅显示适配器中的一个项目。
