保护无效onPostExecute（ArrayList的＆LT;＆配方GT;的结果）{ INT CHEF_ID = ChefsRecipeList.this.getIntent（）getIntExtra（CHEF_ID，0）; ListView控件recipeListView =（ListView控件）findViewById（android.R.id.list）; 查看页脚= getLayoutInflater（）膨胀（R.layout.chef_recipe_list_footer，NULL）;
如果（！addToExisting）{ RecipeManager.getInstance（）setRecipeList（结果）。 查看标题= getLayoutInflater（）膨胀（R.layout.chef_recipe_list_header，NULL）; ImageView的loadButton =（ImageView的）footer.findViewById（R.id.loadmore）; loadButton.setOnClickListener（新OnClickListener（）{ @覆盖
公共无效的onClick（视图v）{ INT CHEF_ID = ChefsRecipeList.this.getIntent（）getIntExtra（CHEF_ID，0）; 尝试{ Log.d（NXTLAOD \"http://api.foodnetworkasia.com/api/mobile/get_recipes?chefId=\"+ChefManager.getInstance().getChef(CHEF_ID).getId()+

Log.d（FOODREM，页脚删除）; } Log.d（ITCOUNT，totalRecipes + - + RecipeManager.getInstance（）getRecipeList（）的大小（））;
updateItemscount（）; }}
解决方案
您可能需要调用 listView1.setAdapter（适配器）来刷新列表视图。如果不工作，另一种解决方案是使页脚视图的高度为0px。这是一个更好的解决方案，如果你打算以后再次上使用的页脚视图。
I am trying to remove footer I've set using the same reference I used to set it up. However, nothing happens.
protected void onPostExecute(ArrayList<Recipe> result) {
int CHEF_ID = ChefsRecipeList.this.getIntent().getIntExtra("CHEF_ID", 0);
ListView recipeListView = (ListView)findViewById(android.R.id.list);
View footer = getLayoutInflater().inflate(R.layout.chef_recipe_list_footer, null);
if(!addToExisting){
RecipeManager.getInstance().setRecipeList(result);
View header = getLayoutInflater().inflate(R.layout.chef_recipe_list_header, null);
ImageView loadButton = (ImageView)footer.findViewById(R.id.loadmore);
loadButton.setOnClickListener( new OnClickListener() {
@Override
public void onClick(View v) {
int CHEF_ID = ChefsRecipeList.this.getIntent().getIntExtra("CHEF_ID", 0);
try {
Log.d("NXTLAOD", "http://api.foodnetworkasia.com/api/mobile/get_recipes?chefId="+ChefManager.getInstance().getChef(CHEF_ID).getId()+
"&format=xml&startIndex="+(RecipeManager.getInstance().getRecipeList().size()+1)+"&endIndex="+(RecipeManager.getInstance().getRecipeList().size()+24));
new XMLRecipesParser(true).execute(new URL[] { new URL("http://api.foodnetworkasia.com/api/mobile/get_recipes?chefId="+ChefManager.getInstance().getChef(CHEF_ID).getId()+
"&format=xml&startIndex="+RecipeManager.getInstance().getRecipeList().size()+"&endIndex="+(RecipeManager.getInstance().getRecipeList().size()+24)) } );
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
});
ImageView chefPhoto = (ImageView)header.findViewById(R.id.chef_photo);
chefPhoto.setImageBitmap(ImageURLLoader.LoadImageFromURL(ChefManager.getInstance().getChef(CHEF_ID).getLargeURL()));
TextView chefBio = (TextView)header.findViewById(R.id.chef_bio);
chefBio.setText(ChefManager.getInstance().getChef(CHEF_ID).getDescription());
recipeListView.addHeaderView(header);
recipeListView.addFooterView(footer);
recipeListView.setAdapter(new RecipeAdapter(ChefsRecipeList.this));
}else{
RecipeManager.getInstance().mergeLists(result);
RecipeAdapter wrapperAdapter=(RecipeAdapter) ((HeaderViewListAdapter)recipeListView.getAdapter()).getWrappedAdapter();
wrapperAdapter.notifyDataSetChanged();
}
if(totalRecipes == RecipeManager.getInstance().getRecipeList().size()){
recipeListView.removeFooterView(footer);
Log.d("FOODREM", "Footer Removed");
}
Log.d("ITCOUNT", totalRecipes+"-"+RecipeManager.getInstance().getRecipeList().size());
updateItemscount();
}
}
解决方案
You might have to call listView1.setAdapter(adapter) to refresh the listview. If that doesn't work, another solution is to make the height of the footer view to 0px. This is a better solution if you are planning to use the footer view later on again.
