Hi下面是我的baseadapter类,但它不能正常工作:
private static class MyBaseAdapter extends BaseAdapter {
private Context context;
private LayoutInflater inflater;
private MyBaseAdapter(Context context, FlipViewController controller) {
inflater = LayoutInflater.from(context);
this.context = context;
}
@Override
public int getCount() {
return Globals.list_album.size();
}
@Override
public Object getItem(int position) {
return position;
}
@Override
public long getItemId(int position) {
return position;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View layout = convertView;
if (convertView == null )
{
if (Globals.list_album.get(position).no_of_images == 1) {
layout = inflater.inflate(R.layout.single_image_adapter, null);
}
else if(Globals.list_album.get(position).no_of_images == 2) {
layout = inflater.inflate(R.layout.two_image_adapter, null);
}
else if(Globals.list_album.get(position).no_of_images == 3) {
layout = inflater.inflate(R.layout.three_image_adapter, null);
}
else if(Globals.list_album.get(position).no_of_images == 4) {
layout = inflater.inflate(R.layout.four_image_adapter, null);
}
else if(Globals.list_album.get(position).no_of_images == 5) {
layout = inflater.inflate(R.layout.five_image_adapter, null);
}
}
return layout;
}
}
我想根据Globals.list_album中每个位置的图像数量加载布局。但它不能正常工作。它不适用于no_of_images=5和2,因为我在列表中有这样的值。目前,no_of_images的值为4,3,1,2和5。因此,它应该显示布局four_image_adapter、three_image_adapter,one_image_aapter、two_image_adapter和five_image_address。但它显示四个图像适配器、三个图像适配器,一个图像适配器和四个图像和三个图像。根据图像的数量,所有布局都具有图像视图。有人能告诉我该做什么吗?
由于不同的行需要不同的布局,请使用以下方法
getViewTypeCount()-返回行类型的信息。
getItemViewType(int position)-返回基于位置应使用的布局类型的信息
使用getItemViewType,您可以定义需要使用的布局。
像这个
public static final int TYPE_1 = 1;
public static final int TYPE_2 = 2;
public int getItemTypeCount(){
return 5;
}
public int getItemType(int position){
// Your if else code and return type ( TYPE_1 to TYPE_5 )
}
public View getView(int position, View convertView, ViewGroup parent){
// Return the right kind of view based on getItemType(position)
int type = getItemType(position);
if(type == TYPE_1){
// create (or reuse) TYPE_1 view
} else if() {
}......
return myView;
}
