This includes validation and submit. 3 | 4 | ## Requires Android Studio 3.2 or Newer 5 | 6 | Since this project uses Jetpack, you're going to need Android Studio 3.2 (currently in RC1) or newer. 7 | 8 | ## Implementation notes 9 | 10 | There are 2 methods used that can be found on branch [`method1`][1] and [`method2`][2]. 11 | [`method1`][1] pushed some of the form state and logic to the ViewModel where as 12 | with [`method2`][2] the fields have their own model and the form has it's own model 13 | and the ViewModel only handles the bindings and exposing fields to the View. 14 | 15 | Which method is better is up to you, while some argue that the ViewModel should 16 | contain the state of the screen/form (i.e. [`method1`][1]), others would argue that the ViewModel is 17 | more of an orchestration layer and should not contain anything to do with the state. 18 | Instead the ViewModel should only expose public properties and commands (i.e. [`method2`][2]). 19 | 20 | Personally I think both are fine, but the actual answer may depends on the size of your app, 21 | and the need for reuse of the logic and models. 22 | 23 | ## More 24 | 25 | More discussion on this code can be found on my Medium blog post [Android — Form input and validation using MVVM with DataBinding][3] 26 | 27 | [1]: https://github.com/alphamu/android-MVVM-DataBinding-FormExample/tree/method1 28 | [2]: https://github.com/alphamu/android-MVVM-DataBinding-FormExample/tree/method2 29 | [3]: https://medium.com/bcgdv-engineering/android-form-input-and-validation-using-mvvm-with-databinding-c416ea6657c9 30 | -------------------------------------------------------------------------------- /app/.gitignore: -------------------------------------------------------------------------------- 1 | /build 2 | -------------------------------------------------------------------------------- /app/build.gradle: -------------------------------------------------------------------------------- 1 | apply plugin: 'com.android.application' 2 | 3 | android { 4 | compileSdkVersion 28 5 | defaultConfig { 6 | applicationId "com.alimuzaffar.testproject" 7 | minSdkVersion 23 8 | targetSdkVersion 28 9 | versionCode 1 10 | versionName "1.0" 11 | testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner" 12 | vectorDrawables.useSupportLibrary = true 13 | } 14 | dataBinding.enabled = true 15 | buildTypes { 16 | release { 17 | minifyEnabled false 18 | proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' 19 | } 20 | } 21 | } 22 | 23 | ext { 24 | retrofitVersion = '2.1.0' 25 | arch_version = '1.1.0' 26 | dagger_version = '2.11' 27 | glideVersion = '4.8.0' 28 | } 29 | dependencies { 30 | implementation fileTree(include: ['*.jar'], dir: 'libs') 31 | implementation 'androidx.appcompat:appcompat:1.0.0' 32 | implementation 'com.google.android.material:material:1.0.0' 33 | implementation 'androidx.lifecycle:lifecycle-extensions:2.0.0' 34 | implementation 'androidx.constraintlayout:constraintlayout:1.1.3' 35 | implementation "com.github.bumptech.glide:glide:$glideVersion" 36 | implementation "com.github.bumptech.glide:okhttp3-integration:$glideVersion" 37 | implementation "com.squareup.retrofit2:retrofit:$retrofitVersion" 38 | implementation "com.squareup.retrofit2:converter-gson:$retrofitVersion" 39 | implementation "android.arch.lifecycle:extensions:$arch_version" 40 | implementation "com.google.dagger:dagger:$dagger_version" 41 | implementation 'com.squareup.okhttp3:logging-interceptor:3.11.0' 42 | 43 | testImplementation 'junit:junit:4.12' 44 | annotationProcessor "android.arch.lifecycle:compiler:$arch_version" 45 | annotationProcessor "com.google.dagger:dagger-compiler:$dagger_version" 46 | annotationProcessor "com.github.bumptech.glide:compiler:$glideVersion" 47 | androidTestImplementation 'androidx.test:runner:1.1.0' 48 | androidTestImplementation 'androidx.test.espresso:espresso-core:3.1.0' 49 | androidTestImplementation 'androidx.test:rules:1.1.0' 50 | } 51 | -------------------------------------------------------------------------------- /app/proguard-rules.pro: -------------------------------------------------------------------------------- 1 | # Add project specific ProGuard rules here. 2 | # You can control the set of applied configuration files using the 3 | # proguardFiles setting in build.gradle. 4 | # 5 | # For more details, see 6 | # http://developer.android.com/guide/developing/tools/proguard.html 7 | 8 | # If your project uses WebView with JS, uncomment the following 9 | # and specify the fully qualified class name to the JavaScript interface 10 | # class: 11 | #-keepclassmembers class fqcn.of.javascript.interface.for.webview { 12 | # public *;
