i want to add a footer layout at the base of the recycler view.Below is my adapter view which inflates header layout as well as other items as well.Help appreciated!
public class SplitMembersAdapter extends RecyclerViewAdapter<SplitMember, SplitMemberViewHolder> {
private final ArrayList<SplitMember> mSplitMembersList;
private final ImageLoader mImageLoader;
private static final int TYPE_HEADER = 0;
private static final int TYPE_ITEM = 1;
private int splitAmount;
private boolean isAmountSplitted;
public SplitMembersAdapter(ArrayList<SplitMember> members,ImageLoader imageLoader) {
mSplitMembersList = members;
mImageLoader = imageLoader;
}
@Override
public int getItemCount() {
return mSplitMembersList.size();
}
@Override
public int getItemViewType(int position) {
if (isPositionHeader(position)) {
return TYPE_HEADER;
}
return TYPE_ITEM;
}
private static boolean isPositionHeader(int position) {
return position == 0;
}
@Override
public SplitMemberViewHolder onCreateViewHolder(ViewGroup viewGroup, int viewType) {
View itemView = LayoutInflater.from(viewGroup.getContext()).
inflate(R.layout.split_member_item_layout, viewGroup, false);
return new SplitMemberViewHolder(itemView);
}
@Override
public void onBindViewHolder(SplitMemberViewHolder viewHolder, int position) {
SplitMember contact = mSplitMembersList.get(position);
viewHolder.splitMemAmount.setText(String.format("%.2f", contact.getShare()));
viewHolder.splitMemberColor.setBackgroundColor(contact.getColor());
if (position == TYPE_HEADER){
viewHolder.splitMemName.setText("You");
mImageLoader.loadImage(contact.getImg(),
viewHolder.splitMemImg, R.drawable.empty_user_placeholder);
}
else {
viewHolder.splitMemName.setText(contact.getName());
mImageLoader.loadImage(Utils.getProfileImageUrl(contact.getImg()),
viewHolder.splitMemImg,R.drawable.empty_user_placeholder);
}
}
}
class SplitMemberViewHolder extends RecyclerView.ViewHolder {
public BezelImageView splitMemImg;
public TextView splitMemName;
public TextView splitMemAmount;
public View splitMemberColor;
public SplitMemberViewHolder(View itemView) {
super(itemView);
splitMemberColor = itemView.findViewById(R.id.member_color);
splitMemImg = (BezelImageView) itemView.findViewById(R.id.member_profile_image);
splitMemName = (TextView) itemView.findViewById(R.id.member_name);
splitMemAmount = (TextView) itemView.findViewById(R.id.member_amount);
}
}
推荐答案
我使用此要点.之后，我可以为自己的页眉和页脚以及其余项添加自己的布局和视图保持器.
I created a wrapper around my adapter using this gist.And after that i can include my own layout and viewholder for my header and footer as well as the rest of the items.
public class SplitMembersAdapter extends HeaderFooterRecyclerViewAdapter implements AutoCompleteContactTextView.ContactSelectListener{
private final ArrayList<SplitMember> mSplitMembersList;
private final ImageLoader mImageLoader;
private static final int TYPE_HEADER = 0;
private static final int TYPE_ITEM = 1;
private static final int TYPE_FOOTER = 2;
private int splitAmount;
private boolean isAmountSplitted;
public SplitMembersAdapter(ArrayList<SplitMember> members, ImageLoader imageLoader) {
mSplitMembersList = members;
mImageLoader = imageLoader;
}
@Override
public boolean useFooter() {
return true;
}
@Override
public RecyclerView.ViewHolder onCreateFooterViewHolder(ViewGroup viewGroup, int viewType) {
View itemView = LayoutInflater.from(viewGroup.getContext()).
inflate(R.layout.split_member_footer_layout, viewGroup, false);
return new SplitMemberFooterViewHolder(itemView);
}
//Binding data wrt to footer
@Override
public void onBindFooterView(final RecyclerView.ViewHolder holder, int position) {
if (holder instanceof SplitMemberFooterViewHolder){
((SplitMemberFooterViewHolder) holder).mAddFriends.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
((SplitMemberFooterViewHolder) holder).mAddFriendPlaceholderTxt.setVisibility(View.GONE);
((SplitMemberFooterViewHolder) holder).mAddFriends.setVisibility(View.GONE);
((SplitMemberFooterViewHolder) holder).mPhoneEnterView.setVisibility(View.VISIBLE);
}
});
((SplitMemberFooterViewHolder) holder).mPhoneEnterView.setmContactSelectListener(this);
((SplitMemberFooterViewHolder) holder).mPhoneEnterView.setDisplayPhoto(true);
((SplitMemberFooterViewHolder) holder).mPhoneEnterView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
((SplitMemberFooterViewHolder) holder).mPhoneEnterView.setCursorVisible(true);
}
});
((SplitMemberFooterViewHolder) holder).mPhoneEnterView.setOnKeyListener(new View.OnKeyListener() {
@Override
public boolean onKey(View view, int keyCode, KeyEvent event) {
if (event.getAction() == KeyEvent.ACTION_UP)
{
switch (keyCode)
{
case KeyEvent.KEYCODE_DPAD_CENTER:
case KeyEvent.KEYCODE_ENTER:
postContact(((SplitMemberFooterViewHolder) holder)
.mPhoneEnterView.getText().toString());
return true;
default:
break;
}
}
return false;
}
});
}
}
@Override
public void onContactSelect(People contact) {
String mobileNum = String.valueOf(contact.getData());
postContact(mobileNum);
}
private static void postContact(String contact) {
EventBus.getDefault().post(new Events(Events.GET_CONTACT,
true, contact));
}
@Override
public RecyclerView.ViewHolder onCreateBasicItemViewHolder(ViewGroup viewGroup, int viewType) {
View itemView = LayoutInflater.from(viewGroup.getContext()).
inflate(R.layout.split_member_item_layout, viewGroup, false);
return new SplitMemberViewHolder(itemView);
}
//Binding data wrt the items
@Override
public void onBindBasicItemView(RecyclerView.ViewHolder holder, int position) {
SplitMember contact = mSplitMembersList.get(position);
if (holder instanceof SplitMemberViewHolder){
((SplitMemberViewHolder) holder).splitMemAmount.setText(String.format("%.2f", contact.getShare()));
((SplitMemberViewHolder) holder).splitMemberColor.setBackgroundColor(contact.getColor());
if (position == TYPE_HEADER) {
((SplitMemberViewHolder) holder).splitMemName.setText("You");
mImageLoader.loadImage(contact.getImg(),
((SplitMemberViewHolder) holder).splitMemImg, R.drawable.empty_user_placeholder);
} else {
((SplitMemberViewHolder) holder).splitMemName.setText(contact.getName());
mImageLoader.loadImage(Utils.getProfileImageUrl(contact.getImg()),
((SplitMemberViewHolder) holder).splitMemImg, R.drawable.empty_user_placeholder);
}
}
}
@Override
public int getBasicItemCount() {
return mSplitMembersList.size();
}
@Override
public int getBasicItemType(int position) {
return position;
}
}
//Seperate viewholders for different footer as well as items
class SplitMemberViewHolder extends RecyclerView.ViewHolder {
public BezelImageView splitMemImg;
public TextView splitMemName;
public TextView splitMemAmount;
public View splitMemberColor;
public SplitMemberViewHolder(View itemView) {
super(itemView);
splitMemberColor = itemView.findViewById(R.id.member_color);
splitMemImg = (BezelImageView) itemView.findViewById(R.id.member_profile_image);
splitMemName = (TextView) itemView.findViewById(R.id.member_name);
splitMemAmount = (TextView) itemView.findViewById(R.id.member_amount);
}
}class SplitMemberFooterViewHolder extends RecyclerView.ViewHolder {
public BezelImageView mAddFriends;
public AutoCompleteContactTextView mPhoneEnterView;
public TextView mAddFriendPlaceholderTxt;
public SplitMemberFooterViewHolder(View itemView) {
super(itemView);
mAddFriends = (BezelImageView) itemView.findViewById(R.id.add_friends_img);
mPhoneEnterView = (AutoCompleteContactTextView) itemView.findViewById(R.id.add_member_edit_text);
mAddFriendPlaceholderTxt = (TextView) itemView.findViewById(R.id.add_friend_static_txt);
}
}
