There are 4 | just a few small guidelines you need to follow. 5 | 6 | ## Contributor License Agreement 7 | 8 | Contributions to this project must be accompanied by a Contributor License 9 | Agreement (CLA). You (or your employer) retain the copyright to your 10 | contribution; this simply gives us permission to use and redistribute your 11 | contributions as part of the project.

The problems are themed around real-world use cases. 4 | 5 | 6 | This repo contains solution to the practice problems. Following is the list of practice problems: 7 | - [Compose Article](https://github.com/google-developer-training/basic-android-kotlin-compose-training-practice-problems/tree/main/Unit%201/Pathway%203/ComposeArticle) 8 | 9 | For Learn Together app, build a screen which displays article about Jetpack Compose Tutorial 10 | - [Task Completed](https://github.com/google-developer-training/basic-android-kotlin-compose-training-practice-problems/tree/main/Unit%201/Pathway%203/TaskCompleted) 11 | 12 | For Task Manager app, build a screen which displays All tasks completed screen. 13 | - [Compose Quadrant](https://github.com/google-developer-training/basic-android-kotlin-compose-training-practice-problems/tree/main/Unit%201/Pathway%203/ComposeQuadrant) 14 | 15 | Build an app that displays the information about the Composable functions. 16 | 17 | 18 | Consider the solutions as one way to solve the problems and feel free to experiment however you feel comfortable. 19 | 20 | Pre-requisites 21 | -------------- 22 | You need to know: 23 | - How to load the project from GitHub into Android Studio and run the app in Android Studio. 24 | 25 | Recommendation: 26 | - Try to solve the problems before you check the solution. 27 | -------------------------------------------------------------------------------- /Unit 1/Pathway 3/ComposeArticle/.gitignore: -------------------------------------------------------------------------------- 1 | # built application files 2 | *.apk 3 | *.ap_ 4 | 5 | # Mac files 6 | .DS_Store 7 | 8 | # files for the dex VM 9 | *.dex 10 | 11 | # Java class files 12 | *.class 13 | 14 | # generated files 15 | bin/ 16 | gen/ 17 | 18 | # Ignore gradle files 19 | .gradle/ 20 | build/ 21 | 22 | # Local configuration file (sdk path, etc) 23 | local.properties 24 | 25 | # Proguard folder generated by Eclipse 26 | proguard/ 27 | proguard-project.txt 28 | 29 | # Eclipse files 30 | .project 31 | .classpath 32 | .settings/ 33 | 34 | # Android Studio/IDEA 35 | *.iml 36 | .idea 37 | -------------------------------------------------------------------------------- /Unit 1/Pathway 3/ComposeArticle/README.md: -------------------------------------------------------------------------------- 1 | # Compose Article - Solution Code 2 | 3 | This project contains solution code for Compose Article practice problem. In the exercise, you need to build a screen which displays article about Jetpack Compose Tutorial. 4 | 5 | ## Solution 6 | 7 | 1. Download the image from the URL given in practice problem 8 | 2. Import the image in the ComposeArticle project 9 | 3. Use `Column` composable function to arrange the components vertically: 10 | 11 | ``` 12 | Column(){ 13 | // Load image using painterResource() 14 | Image(...) 15 | // Load text using stringResource() 16 | Text(...) 17 | // Load text using stringResource() 18 | Text(...) 19 | } 20 | ``` 21 | 22 | ## Note: 23 | 24 | The solution code uses the basic composables covered in Unit 1, Pathway 3 for Android Basics in Compose: 25 | - [Build a simple app with text composables](https://developer.android.com/codelabs/basic-android-kotlin-compose-text-composables#0) 26 | - [Add images to your Android app](https://developer.android.com/codelabs/basic-android-kotlin-compose-add-images#0) 27 | 28 | There's a lot of room for improvement, so feel free to experiment and try different things. 29 |

tutorial 22 | Jetpack Compose is a modern toolkit for building native Android UI. Compose simplifies and accelerates UI development on Android with less code, powerful tools, and intuitive Kotlin APIs. 23 | In this tutorial, you build a simple UI component with declarative functions. You call Compose functions to say what elements you want and the Compose compiler does the rest. Compose is built around Composable functions. These functions let you define your app\'s UI programmatically because they let you describe how it should look and provide data dependencies, rather than focus on the process of the UI\'s construction, such as initializing an element and then attaching it to a parent. To create a Composable function, you add the @Composable annotation to the function name. 24 | 25 | -------------------------------------------------------------------------------- /Unit 1/Pathway 3/ComposeArticle/app/src/main/res/values/themes.xml: -------------------------------------------------------------------------------- 1 | 2 | 17 | 18 | 19 | 20 |
