It provides an easy and effortless way of navigating between different screens by taking care of back navigation and view persistence. BackStack is designed to be used under a view group based navigation system, a movement began by square [in 2014](https://medium.com/square-corner-blog/advocating-against-android-fragments-81fd0b462c97). 7 | 8 | 9 | Get it on Google Play 14 | 15 | 16 | Using view groups come with some inherent obstacles. They don't come with back navigation and view tree persistence built in. BackStack aims to overcome these limitations of view groups and make them a viable choice for use in-place of fragments or activities. BackStack is built around the concept of a view creator, a contextless object that does what it's name says, creates views. Each view creator is associated with a particular view group. View creators don't hold state about what they create or who told them to create what. By doing this, each view group can be inflated independent of each other regardless of the order or conditions they were first created in. BackStack stores a stack of view creators in chronological order. The view creator at the top of the stack will inflate the view that is actually shown to the user. Using this stack, BackStack can return to any previous views. View creators are contextless, and therefore they can also be persisted through activity restarts without leaking. 17 | 18 | ## Using BackStack 19 | 20 | #### Adding BackStack 21 | 22 | Using gradle: 23 | 24 | build.gradle (Project) 25 | ~~~Gradle 26 | allprojects{ 27 | repositories{ 28 | jcenter() 29 | maven{ 30 | url 'https://jitpack.io' 31 | } 32 | } 33 | } 34 | ~~~ 35 | 36 | build.gradle (Module) 37 | ~~~Gradle 38 | dependencies{ 39 | compile 'com.github.kevinwang5658:backstack:v2.3' 40 | } 41 | ~~~ 42 | 43 | #### Initialization 44 | 45 | To initialize BackStack add the following code to onCreate(). 46 | 47 | ~~~Java 48 | public class MainActivity extends AppCompatActivity { 49 | 50 | BackStackManager backStackManager; 51 | 52 | @Override 53 | protected void onCreate(Bundle savedInstanceState) { 54 | ... 55 | 56 | BackStack.install(this); 57 | backStackManager = BackStack.getBackStackManager(); 58 | } 59 | 60 | @Override 61 | public void onBackPressed() { 62 | if (!backStackManager.goBack()) { 63 | super.onBackPressed(); 64 | } 65 | } 66 | } 67 | ~~~ 68 | 69 | #### Creating a Simple Back Stack 70 | 71 | ```Java 72 | public static final String TAG = "TAG"; 73 | 74 | @Override 75 | protected void onCreate(Bundle savedInstanceState) { 76 | super.onCreate(savedInstanceState); 77 | setContentView(R.layout.activity_main); 78 | BackStack.install(this); 79 | backStackManager = BackStack.getBackStackManager(); 80 | 81 | //This is the container you want to be the root of your back stack 82 | root = findViewById(R.id.root); 83 | 84 | LinearBackStack linearBackStack = backStackManager.createLinearBackStack("TAG", root, (layoutInflater, container) -> { 85 | //This is our first view group in the stack 86 | CustomViewGroup cvg = new CustomViewGroup(layoutInflater.getContext()); 87 | 88 | //Make sure that the view is added to container by the end of this block 89 | container.addView(cvg); 90 | 91 | //Return the view group that was newly inflated 92 | return cvg; 93 | }); 94 | } 95 | ``` 96 | 97 | #### Adding Subsequent View Groups 98 | 99 | ```Java 100 | setOnClickListener(v -> { 101 | //All back stacks can be retrieved anywhere using their tag 102 | LinearBackStack linearBackStack = (LinearBackStack) BackStack.getStack(MainActivity.TAG); 103 | linearBackStack.add((layoutInflater, container) -> { 104 | //if attach to root is true layoutInflater.inflate() returns the container instead 105 | ViewGroup viewGroup = (ViewGroup) layoutInflater 106 | .inflate(R.layout.added_view, container, false); 107 | container.addView(viewGroup); 108 | return viewGroup; 109 | }); 110 | }); 111 | ``` 112 | 113 | For more information please refer to [here](https://kevinwang5658.github.io/backstack/) 114 | 115 | ## License 116 | ``` 117 | Copyright 2017 Kevin Wang 118 | 119 | Licensed under the Apache License, Version 2.0 (the "License");
