我的自定义ListView没有显示所有列表项。检查我的活动和xml，请告诉我我的问题是什么。我有30项。但Listview只显示25项。
以下是我的customlistview活动：
public class DrawableYerliListAdapter extends BaseAdapter {
private List<Integer> list;
private final String[] stationName;
public DrawableYerliListAdapter(Context context) {
list = new ArrayList<Integer>();
stationName = context.getResources().getStringArray(R.array.yerli_tv);
}
@Override
public int getCount() {
if (list == null)
return 0;
return list.size();
}
@Override
public Object getItem(int arg0) {
return list.get(arg0);
}
@Override
public long getItemId(int arg0) {
return arg0;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
if (convertView == null) {
LayoutInflater inflater = LayoutInflater.from(parent.getContext());
convertView = inflater.inflate(R.layout.yerlikanal_list_item,
parent, false);
}
Integer data = list.get(position);
TextView nameView = (TextView) convertView.findViewById(R.id.title);
nameView.setText(stationName[position]);
ImageView imageView = (ImageView) convertView.findViewById(R.id.image);
imageView.setImageResource(data);
return convertView;
}
public int getImageResource(int position) {
return list.get(position);
}
public String getStationName(int position) {
return stationName[position];
}
public void setData(List<Integer> data) {
list = data;
}
这是我的xml文件：
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<!--
The frame layout is here since we will be showing either
the empty view or the list view.
-->
<FrameLayout
android:id="@+id/list_show"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<!--
Here is the list. Since we are using a ListActivity, we
have to call it "@android:id/list" so ListActivity will
find it
-->
<ListView
android:id="@+id/list"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:drawSelectorOnTop="false"
android:visibility="visible" />
<!-- Here is the view to show if the list is emtpy -->
<TextView
android:id="@+id/empty"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:text="No items."
android:textAppearance="?android:attr/textAppearanceMedium"
android:visibility="gone" />
</FrameLayout>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent" >
<ProgressBar
android:id="@+id/load"
style="?android:attr/progressBarStyleLarge"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:visibility="gone" />
</RelativeLayout>
<!--
<include layout="@layout/play_bar"/>-->
</RelativeLayout>

答案 0 :(得分：0)
假设您在从适配器类创建对象后调用setData（），请不要在构造函数中包含它。如果只有25个项目，你应该看看你传递给setData（）函数的参数。
