15 | Loading Item | Error Item
16 | :-------------------------:|:-------------------------:
17 |  |

19 |
20 |
21 | ### Gradle
22 |
23 | ```
24 | implementation 'ru.alexbykov:nopaginate:0.9.9'
25 | ```
26 |
27 | ### Install
28 | ```java
29 | NoPaginate noPaginate = NoPaginate.with(recyclerView)
30 | .setOnLoadMoreListener(new OnLoadMoreListener() {
31 | @Override
32 | public void onLoadMore() {
33 | //http or db request
34 | }
35 | })
36 | .build();
37 | ```
38 |
39 |
40 |
41 | If you use ```MVP``` or ```Clean Architecture```, don't forget implement ```PaginateView```.
42 | You can see example of implementation with MVP [here](https://github.com/NoNews/NoPaginate/tree/master/sample/src/main/java/ru/alexbykov/pagination)
43 |
44 | ### Actions
45 | ```java
46 | noPaginate.showLoading(show);
47 | noPaginate.showError(show);
48 | noPaginate.setNoMoreItems(set); //Method onLoadMore will not to call
49 | noPaginate.unbind(); //Don't forget call it on onDestroy();
50 | ```
51 |
52 | ### Custom Loading and Error
53 | For custom error and loaging item just implement the interfaces ```ErrorItem``` or ```LoadingItem```
54 |
55 | #### Custom error:
56 | ```java
57 | public class CustomErrorItem implements ErrorItem {
58 |
59 | @Override
60 | public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
61 | View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_error, parent, false);
62 | return new RecyclerView.ViewHolder(view) {
63 | };
64 | }
65 |
66 | @Override
67 | public void onBindViewHolder(RecyclerView.ViewHolder holder, int position, final OnRepeatListener repeatListener) {
68 | Button btnRepeat = (Button) holder.itemView.findViewById(R.id.btnRepeat);
69 | btnRepeat.setOnClickListener(new View.OnClickListener() {
70 | @Override
71 | public void onClick(View v) {
72 | if (repeatListener != null) {
73 | repeatListener.onClickRepeat(); //call onLoadMore
74 | }
75 | }
76 | });
77 | }
78 | }
79 | ```
80 |
81 |
82 | #### Custom loading:
83 | ```java
84 | public class CustomLoadingItem implements LoadingItem {
85 |
86 | @Override
87 | public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
88 | View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_loading, parent, false);
89 | return new RecyclerView.ViewHolder(view) {
90 | };
91 | }
92 | @Override
93 | public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
94 |
95 | }
96 |
97 | }
98 | ```
99 |
100 | #### Install with custom items and trigger threshold
101 |
102 | ```java
103 |
104 | NoPaginate noPaginate = NoPaginate.with(recyclerView)
105 | .setOnLoadMoreListener(new OnLoadMoreListener() {
106 | @Override
107 | public void onLoadMore() {
108 | //http or db request
109 | }
110 | })
111 | .setLoadingTriggerThreshold(5) //0 by default
112 | .setCustomErrorItem(new CustomErrorItem())
113 | .setCustomLoadingItem(new CustomLoadingItem())
114 | .build();
115 | ```
116 |
117 |
118 | #### Idea
119 | This repository is a slightly modified version of [Paginate](https://github.com/MarkoMilos/Paginate) library.
120 | Author: [@MarkoMilos](https://github.com/MarkoMilos)
121 |
122 | We decided to modify it a little, so that developers could easily use it with MVP or Clean Architecture
123 |
124 |
125 | #### Roadmap
126 | 1. Double-sided pagination
127 | 2. Delegate for ```Presenter``` or ```Interactor```, with implementation Limit/Offset and Page pagination
128 | 3. Unit tests
129 | 4. Wiki
130 |
131 | #### Contributing

84 | or a Contribution incorporated within the Work constitutes direct
85 | or contributory patent infringement, then any patent licenses
86 | granted to You under this License for that Work shall terminate
87 | as of the date such litigation is filed.
88 |
89 | 4. Redistribution. You may reproduce and distribute copies of the
90 | Work or Derivative Works thereof in any medium, with or without
91 | modifications, and in Source or Object form, provided that You

97 | (b) You must cause any modified files to carry prominent notices
98 | stating that You changed the files; and
99 |
100 | (c) You must retain, in the Source form of any Derivative Works

104 | the Derivative Works; and
105 |
106 | (d) If the Work includes a "NOTICE" text file as part of its
107 | distribution, then any Derivative Works that You distribute must
108 | include a readable copy of the attribution notices contained

110 | pertain to any part of the Derivative Works, in at least one
111 | of the following places: within a NOTICE text file distributed
112 | as part of the Derivative Works; within the Source form or
113 | documentation, if provided along with the Derivative Works; or,
114 | within a display generated by the Derivative Works, if and
115 | wherever such third-party notices normally appear. The contents
116 | of the NOTICE file are for informational purposes only and
117 | do not modify the License. You may add Your own attribution
118 | notices within Derivative Works that You distribute, alongside
119 | or as an addendum to the NOTICE text from the Work, provided
120 | that such additional attribution notices cannot be construed
121 | as modifying the License.
122 |
123 | You may add Your own copyright statement to Your modifications and

128 | the conditions stated in this License.
129 |
130 | 5. Submission of Contributions. Unless You explicitly state otherwise,
131 | any Contribution intentionally submitted for inclusion in the Work
132 | by You to the Licensor shall be under the terms and conditions of
133 | this License, without any additional terms or conditions.

135 | the terms of any separate license agreement you may have executed
136 | with Licensor regarding such Contributions.
137 |
138 | 6. Trademarks. This License does not grant permission to use the trade
139 | names, trademarks, service marks, or product names of the Licensor,
140 | except as required for reasonable and customary use in describing the
141 | origin of the Work and reproducing the content of the NOTICE file.
142 |
143 | 7. Disclaimer of Warranty. Unless required by applicable law or
144 | agreed to in writing, Licensor provides the Work (and each
145 | Contributor provides its Contributions) on an "AS IS" BASIS,
146 | WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
147 | implied, including, without limitation, any warranties or conditions
148 | of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
149 | PARTICULAR PURPOSE. You are solely responsible for determining the
150 | appropriateness of using or redistributing the Work and assume any
151 | risks associated with Your exercise of permissions under this License.

154 | whether in tort (including negligence), contract, or otherwise,
155 | unless required by applicable law (such as deliberate and grossly
156 | negligent acts) or agreed to in writing, shall any Contributor be
157 | liable to You for damages, including any direct, indirect, special,
158 | incidental, or consequential damages of any character arising as a
159 | result of this License or out of the use or inability to use the
160 | Work (including but not limited to damages for loss of goodwill,
161 | work stoppage, computer failure or malfunction, or any and all
162 | other commercial damages or losses), even if such Contributor
163 | has been advised of the possibility of such damages.
164 |
165 | 9. Accepting Warranty or Additional Liability. While redistributing
166 | the Work or Derivative Works thereof, You may choose to offer,
167 | and charge a fee for, acceptance of support, warranty, indemnity,
168 | or other liability obligations and/or rights consistent with this
169 | License. However, in accepting such obligations, You may act only
170 | on Your own behalf and on Your sole responsibility, not on behalf
171 | of any other Contributor, and only if You agree to indemnify,
172 | defend, and hold each Contributor harmless for any liability
173 | incurred by, or claims asserted against, such Contributor by reason
174 | of your accepting any such warranty or additional liability.
