1 | # PdfViewPager
2 |
3 | Android widget to display PDF documents in your Activities or Fragments.
4 |
5 | Important note: **PDFViewPager** uses *PdfRenderer* class, which works **only on API 21 or later**.
6 | See [PDFRenderer documentation][6].
7 |
8 | If you are targeting pre-Lollipop devices, have a look at the [legacy sample][7]
9 |
10 | Installation
11 | ------------
12 |
13 | hopefully, the library will be available soon as a gradle dependency.
14 | In the meanwhile, you can checkout the source.
15 |
16 | Usage - Remote PDF's
17 | --------------------
18 |
19 | ![Screenshot][remotePDFScreenshot]
20 |
21 | Use **RemotePDFViewPager** to load from remote URLs
22 |
23 | 1.- Add INTERNET, READ_EXTERNAL_STORAGE and WRITE_EXTERNAL_STORAGE permissions on your AndroidManifest.xml
24 |
25 |
26 |
27 |
28 |
29 | 2.- Make your Activity or Fragment implement DownloadFile.Listener
30 |
31 | public class RemotePDFActivity extends AppCompatActivity implements DownloadFile.Listener {
32 |
33 | 3.- Create a **RemotePDFViewPager** object
34 |
35 | RemotePDFViewPager remotePDFViewPager =
36 | new RemotePDFViewPager(context, "http://partners.adobe.com/public/developer/en/xml/AdobeXMLFormsSamples.pdf", this);
37 |
38 | 4.- Configure the corresponding callbacks and they will be called on each situation.
39 |
40 | @Override
41 | public void onSuccess(String url, String destinationPath) {
42 | // That's the positive case. PDF Download went fine
43 |
44 | adapter = new PDFPagerAdapter(this, "AdobeXMLFormsSamples.pdf");
45 | remotePDFViewPager.setAdapter(adapter);
46 | setContentView(remotePDFViewPager);
47 | }
48 |
49 | @Override
50 | public void onFailure(Exception e) {
51 | // This will be called if download fails
52 | }
53 |
54 | @Override
55 | public void onProgressUpdate(int progress, int total) {
56 | // You will get download progress here
57 | // Always on UI Thread so feel free to update your views here
58 | }
59 |
60 | 5.- Don't forget to close adapter in *onDestroy* to release all resources
61 |
62 | @Override
63 | protected void onDestroy() {
64 | super.onDestroy();
65 |
66 | adapter.close();
67 | }
68 |
69 | Usage - Local PDF's
70 | -------------------
71 |
72 | Use **PDFViewPager** class to load PDF from assets
73 |
74 | ![Screenshot][localPDFScreenshot]
75 |
76 | 1.- Copy your assets to cache directory (lib will do that for you in future versions)
77 |
78 | CopyAsset copyAsset = new CopyAssetThreadImpl(context, new Handler());
79 | copyAsset.copy(asset, new File(getCacheDir(), "sample.pdf").getAbsolutePath());
80 |
81 | 2.- Create your **PDFViewPager** passing your PDF file, located in *assets* (see [sample][8])
82 |
83 | pdfViewPager = new PDFViewPager(this, "sample.pdf");
84 |
85 | 2b.- Or directly, declare it on your XML layout
86 |
87 |
92 |
93 | 3.- Release adapter in *onDestroy*
94 |
95 | @Override
96 | protected void onDestroy() {
97 | super.onDestroy();
98 |
99 | ((PDFPagerAdapter)pdfViewPager.getAdapter()).close();
100 | }
101 |
102 | Usage - PDF's on SD card
103 | ------------------------
104 |
105 | ![Screenshot][sdcardPDFScreenshot]
106 |
107 | Use **PDFViewPager** class to load PDF from your SD card
108 |
109 | 1.- Create a **PDFViewPager** object, passing the file location in your SD card
110 |
111 | PDFViewPager pdfViewPager = new PDFViewPager(context, getPdfPathOnSDCard());
112 |
113 | protected String getPdfPathOnSDCard() {
114 | File f = new File(getExternalFilesDir("pdf"), "adobe.pdf");
115 | return f.getAbsolutePath();
116 | }
117 |
118 | TODOs
119 | -----
120 |
121 | - [X] Load PDF documents from SD card
122 | - [ ] Make PDF documents zoomable with pinch and double tap
123 | - [ ] Unify all features in only one **PDFViewPager** class
124 | - [X] Support API Levels under 21, by downloading PDF and invoking system native intent.
125 | - [ ] UI tests

41 | form, that is based on (or derived from) the Work and for which the

67 | this License, each Contributor hereby grants to You a perpetual,
68 | worldwide, non-exclusive, no-charge, royalty-free, irrevocable

86 | granted to You under this License for that Work shall terminate
87 | as of the date such litigation is filed.
88 |

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

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.

134 | Notwithstanding the above, nothing herein shall supersede or modify
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.
152 |

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.
