If you want to use some parts of this repository in your project read below. 10 | 11 | 12 | ### Change your gradle file 13 | 14 | - In your main build.gradle add: 15 | 16 | ```gradle 17 | classpath 'com.android.tools.build:gradle:1.5.0' 18 | ``` 19 | 20 | - In your app build.gradle add: 21 | 22 | 23 | ```gradle 24 | dataBinding { 25 | enabled = true 26 | } 27 | ``` 28 | 29 | 30 | 31 | ### Modify your layout 32 | 33 | Remember to use your classes and packages ;-). 34 | 35 | ```xml 36 | 37 | 39 | 40 | 43 | 44 | 45 | 53 | 54 | ``` 55 | 56 | ### Modify your activity 57 | 58 | ```java 59 | // your activity 60 | @Override 61 | protected void onCreate(Bundle savedInstanceState) 62 | { 63 | super.onCreate(savedInstanceState); 64 | usersViewModel = new UsersViewModel(); 65 | usersViewModel.users.add(new SuperUserViewModel(new User("Android", "Dev"))); 66 | 67 | binding = DataBindingUtil.setContentView(this, R.layout.users_view); 68 | binding.setUsersViewModel(usersViewModel); 69 | binding.activityUsersRecycler.setLayoutManager(new LinearLayoutManager(this)); 70 | } 71 | ``` 72 | 73 | ### Modify your ViewModel class 74 | 75 | ```java 76 | public class UsersViewModel extends BaseObservable 77 | { 78 | public ObservableArrayList users; 79 | 80 | public ItemBinder itemViewBinder() 81 | { 82 | return new ItemBinderBase(BR.user, R.layout.item_user); 83 | } 84 | } 85 | ``` 86 | 87 | ### Some details 88 | 89 | Your ViewModel (__UsersViewModel__ in my example) should have field of __ObservableArrayList__ type which will be bind to recycler view. 90 | 91 | Next thing is __ItemViewBinder__. This class is used in __BindingRecyclerViewAdapter__ for creating ViewHolders and it's item views bindings. In my example I've created __CompositeItemBinder__ in order to support two different item types with separate layouts. If you want to display list with one data type you can use ItemBinderBase: 92 | 93 | ```java 94 | public ItemBinder itemViewBinder() 95 | { 96 | return new ItemBinderBase(BR.your_variable_name, R.layout.your_item_layout); 97 | } 98 | ``` 99 | 100 | Please look at **UsersView.java** and **UsersViewModel.java** if something is unclear. 101 | -------------------------------------------------------------------------------- /app/.gitignore: -------------------------------------------------------------------------------- 1 | /build 2 | -------------------------------------------------------------------------------- /app/build.gradle: -------------------------------------------------------------------------------- 1 | apply plugin: 'com.android.application' 2 | 3 | repositories { 4 | jcenter() 5 | mavenCentral() 6 | // for snapshots only 7 | // maven { 8 | // url "https://oss.sonatype.org/content/repositories/snapshots" 9 | // } 10 | } 11 | 12 | android { 13 | compileSdkVersion 23 14 | buildToolsVersion '23.0.2' 15 | 16 | defaultConfig { 17 | applicationId "net.droidlabs.mvvmdemo" 18 | minSdkVersion 19 19 | targetSdkVersion 23 20 | versionCode 1 21 | versionName "1.0" 22 | } 23 | buildTypes { 24 | release { 25 | minifyEnabled false 26 | proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' 27 | } 28 | } 29 | 30 | lintOptions { 31 | abortOnError false 32 | } 33 | 34 | dataBinding { 35 | enabled = true 36 | } 37 | 38 | } 39 | 40 | dependencies { 41 | compile fileTree(dir: 'libs', include: ['*.jar']) 42 | compile 'com.android.support:appcompat-v7:23.1.1' 43 | compile 'com.android.support:recyclerview-v7:23.1.1' 44 | compile 'com.android.support:support-annotations:23.1.1' 45 | //compile 'net.droidlabs.mvvm:recyclerview:0.0.2' 46 | //compile 'com.github.radzio:android-data-binding-recyclerview:0.0.3' 47 | compile project(":recyclerview-binding") 48 | 49 | testCompile 'junit:junit:4.12' 50 | testCompile 'org.mockito:mockito-core:1.10.19' 51 | } -------------------------------------------------------------------------------- /app/proguard-rules.pro: -------------------------------------------------------------------------------- 1 | # Add project specific ProGuard rules here. 2 | # By default, the flags in this file are appended to flags specified 3 | # in D:\Tools\android\sdk/tools/proguard/proguard-android.txt 4 | # You can edit the include path and order by changing the proguardFiles 5 | # directive in build.gradle. 6 | # 7 | # For more details, see 8 | # http://developer.android.com/guide/developing/tools/proguard.html 9 | 10 | # Add any project specific keep options here: 11 | 12 | # If your project uses WebView with JS, uncomment the following 13 | # and specify the fully qualified class name to the JavaScript interface 14 | # class: 15 | #-keepclassmembers class fqcn.of.javascript.interface.for.webview { 16 | # public *;
