TransitionAnimation | 14 | | --- | --- | 15 | 16 | 17 | # Usage 18 | 1. Define `FROM` and `TO` elements with shared tag 19 | ```kotlin 20 | @Composable 21 | fun ScreenA() { 22 | // ... 23 | 24 | SharedElement(tag = "tag", type = SharedElementType.FROM) { 25 | Image(image, Modifier.preferredSize(48.dp)) 26 | } 27 | 28 | // ... 29 | } 30 | 31 | @Composable 32 | fun ScreenB() { 33 | // ... 34 | 35 | SharedElement(tag = "tag", type = SharedElementType.TO) { 36 | Image(image, Modifier.preferredSize(200.dp)) 37 | } 38 | 39 | // ... 40 | } 41 | ``` 42 | 43 | 2. Make `SharedElementsRoot` a common parent of `ScreenA` and `ScreenB`. It doesn't have to be their direct parent. 44 | ```kotlin 45 | SharedElementsRoot { 46 | // change between ScreenA and ScreenB 47 | } 48 | ``` 49 | 50 | 3. Transition starts automatically when second `SharedElement` is detected 51 | 52 | # Sample 53 | See sample usage with `UsersListScreen` and `UserDetailsScreen` [here](sample/src/main/java/com/mobnetic/compose/sharedelement/sample/MainActivity.kt). 54 | 55 | # Issues 56 | Considering the experimental state of this library and state of Jetpack Compose itself there are some issues described [here](https://github.com/mobnetic/compose-shared-element/issues). 57 | -------------------------------------------------------------------------------- /build.gradle: -------------------------------------------------------------------------------- 1 | // Top-level build file where you can add configuration options common to all sub-projects/modules. 2 | buildscript { 3 | 4 | ext.kotlin_version = "1.3.72" 5 | ext.compose_version = "0.1.0-dev08" 6 | 7 | repositories { 8 | google() 9 | jcenter() 10 | } 11 | dependencies { 12 | classpath "com.android.tools.build:gradle:4.1.0-alpha05" 13 | classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version" 14 | 15 | // NOTE: Do not place your application dependencies here; they belong 16 | // in the individual module build.gradle files 17 | } 18 | } 19 | 20 | allprojects { 21 | repositories { 22 | google() 23 | jcenter() 24 | } 25 | } 26 | 27 | task clean(type: Delete) { 28 | delete rootProject.buildDir 29 | } -------------------------------------------------------------------------------- /gradle.properties: -------------------------------------------------------------------------------- 1 | # Project-wide Gradle settings. 2 | # IDE (e.g. Android Studio) users: 3 | # Gradle settings configured through the IDE *will override* 4 | # any settings specified in this file. 5 | # For more details on how to configure your build environment visit 6 | # http://www.gradle.org/docs/current/userguide/build_environment.html 7 | # Specifies the JVM arguments used for the daemon process. 8 | # The setting is particularly useful for tweaking memory settings. 9 | org.gradle.jvmargs=-Xmx2048m 10 | # When configured, Gradle will run in incubating parallel mode. 11 | # This option should only be used with decoupled projects.
