-------------------------------------------------------------------------------- /import-summary.txt: -------------------------------------------------------------------------------- 1 | ECLIPSE ANDROID PROJECT IMPORT SUMMARY 2 | ====================================== 3 | 4 | Ignored Files: 5 | -------------- 6 | The following files were *not* copied into the new Gradle project; you 7 | should evaluate whether these are still needed in your project and if 8 | so manually move them: 9 | 10 | * ic_launcher-web.png 11 | * proguard-project.txt 12 | 13 | Replaced Jars with Dependencies: 14 | -------------------------------- 15 | The importer recognized the following .jar files as third party 16 | libraries and replaced them with Gradle dependencies instead. This has 17 | the advantage that more explicit version information is known, and the 18 | libraries can be updated automatically. However, it is possible that 19 | the .jar file in your project was of an older version than the 20 | dependency we picked, which could render the project not compileable. 21 | You can disable the jar replacement in the import wizard and try again: 22 | 23 | android-support-v4.jar => com.android.support:support-v4:19.1.0 24 | 25 | Moved Files: 26 | ------------ 27 | Android Gradle projects use a different directory structure than ADT 28 | Eclipse projects. Here's how the projects were restructured: 29 | 30 | * AndroidManifest.xml => app\src\main\AndroidManifest.xml 31 | * assets\ => app\src\main\assets\ 32 | * res\ => app\src\main\res\ 33 | * src\ => app\src\main\java\ 34 | 35 | Next Steps: 36 | ----------- 37 | You can now build the project. The Gradle project needs network 38 | connectivity to download dependencies. 39 | 40 | Bugs: 41 | ----- 42 | If for some reason your project does not build, and you determine that 43 | it is due to a bug or limitation of the Eclipse to Gradle importer, 44 | please file a bug at http://b.android.com with category 45 | Component-Tools. 46 | 47 | (This import summary is for your information only, and can be deleted 48 | after import once you are satisfied with the results.) 49 | -------------------------------------------------------------------------------- /app/src/main/java/com/example/testscroll/model/MyPage.java: -------------------------------------------------------------------------------- 1 | package com.example.testscroll.model; 2 | 3 | import org.litepal.crud.DataSupport; 4 | 5 | /** 6 | * Author: duanlei 7 | * Date: 2015-12-10 8 | */ 9 | public class MyPage extends DataSupport { 10 | 11 | 12 | private int id; 13 | private int bookId; 14 | private int chapter; 15 | private int startPosition; 16 | private int pageSize; 17 | 18 | private String FileName; 19 | 20 | public MyPage() { 21 | 22 | } 23 | 24 | public int getId() { 25 | return id; 26 | } 27 | 28 | public void setId(int id) { 29 | this.id = id; 30 | } 31 | 32 | public int getBookId() { 33 | return bookId; 34 | } 35 | 36 | public void setBookId(int bookId) { 37 | this.bookId = bookId; 38 | } 39 | 40 | public int getChapter() { 41 | return chapter; 42 | } 43 | 44 | public void setChapter(int chapter) { 45 | this.chapter = chapter; 46 | } 47 | 48 | public int getStartPosition() { 49 | return startPosition; 50 | } 51 | 52 | public void setStartPosition(int startPosition) { 53 | this.startPosition = startPosition; 54 | } 55 | 56 | public int getPageSize() { 57 | return pageSize; 58 | } 59 | 60 | public void setPageSize(int pageSize) { 61 | this.pageSize = pageSize; 62 | } 63 | 64 | public String getFileName() { 65 | return FileName; 66 | } 67 | 68 | public void setFileName(String fileName) { 69 | FileName = fileName; 70 | } 71 | 72 | @Override 73 | public String toString() { 74 | return "MyPage{" + 75 | "id=" + id + 76 | ", bookId=" + bookId + 77 | ", chapter=" + chapter + 78 | ", startPosition=" + startPosition + 79 | ", pageSize=" + pageSize + 80 | ", FileName='" + FileName + '\'' + 81 | '}'; 82 | } 83 | } 84 | -------------------------------------------------------------------------------- /gradlew.bat: -------------------------------------------------------------------------------- 1 | @if "%DEBUG%" == "" @echo off 2 | @rem ########################################################################## 3 | @rem 4 | @rem Gradle startup script for Windows 5 | @rem 6 | @rem ########################################################################## 7 | 8 | @rem Set local scope for the variables with windows NT shell 9 | if "%OS%"=="Windows_NT" setlocal 10 | 11 | @rem Add default JVM options here.
