## Public methods
### getProgressBarManager
Added in [1.1.0](https://developer.android.com/jetpack/androidx/releases/leanback#1.1.0)
```
public final ProgressBarManager getProgressBarManager()
```
Returns the `https://developer.android.com/reference/androidx/leanback/app/ProgressBarManager`.
| Returns |
|---|---|
| `https://developer.android.com/reference/androidx/leanback/app/ProgressBarManager` | The `https://developer.android.com/reference/androidx/leanback/app/ProgressBarManager`. |
### onCreate
```
public void onCreate(Bundle savedInstanceState)
```
Called to do initial creation of a fragment. This is called after `https://developer.android.com/reference/androidx/fragment/app/Fragment#onAttach(android.app.Activity)` and before `https://developer.android.com/reference/androidx/fragment/app/Fragment#onCreateView(android.view.LayoutInflater,android.view.ViewGroup,android.os.Bundle)`.
Note that this can be called while the fragment's activity is still in the process of being created. As such, you can not rely on things like the activity's content view hierarchy being initialized at this point. If you want to do work once the activity itself is created, add a `https://developer.android.com/reference/androidx/lifecycle/LifecycleObserver` on the activity's Lifecycle, removing it when it receives the `https://developer.android.com/reference/androidx/lifecycle/Lifecycle.State#CREATED` callback.
Any restored child fragments will be created before the base `Fragment.onCreate` method returns.
| Parameters |
|---|---|
| `https://developer.android.com/reference/android/os/Bundle.html savedInstanceState` | If the fragment is being re-created from a previous saved state, this is the state. |
### onDestroyView
```
public void onDestroyView()
```
Called when the view previously created by `https://developer.android.com/reference/androidx/fragment/app/Fragment#onCreateView(android.view.LayoutInflater,android.view.ViewGroup,android.os.Bundle)` has been detached from the fragment. The next time the fragment needs to be displayed, a new view will be created. This is called after `https://developer.android.com/reference/androidx/fragment/app/Fragment#onStop()` and before `https://developer.android.com/reference/androidx/fragment/app/Fragment#onDestroy()`. It is called *regardless* of whether `https://developer.android.com/reference/androidx/fragment/app/Fragment#onCreateView(android.view.LayoutInflater,android.view.ViewGroup,android.os.Bundle)` returned a non-null view. Internally it is called after the view's state has been saved but before it has been removed from its parent.
### onViewCreated
```
public void onViewCreated(@NonNull View view, @Nullable Bundle savedInstanceState)
```
Called immediately after `https://developer.android.com/reference/androidx/fragment/app/Fragment#onCreateView(android.view.LayoutInflater,android.view.ViewGroup,android.os.Bundle)` has returned, but before any saved state has been restored in to the view. This gives subclasses a chance to initialize themselves once they know their view hierarchy has been completely created. The fragment's view hierarchy is not however attached to its parent at this point.
| Parameters |
|---|---|
| `@https://jspecify.dev/docs/api/org/jspecify/annotations/NonNull.html https://developer.android.com/reference/android/view/View.html view` | The View returned by `https://developer.android.com/reference/androidx/fragment/app/Fragment#onCreateView(android.view.LayoutInflater,android.view.ViewGroup,android.os.Bundle)`. |
| `@https://jspecify.dev/docs/api/org/jspecify/annotations/Nullable.html https://developer.android.com/reference/android/os/Bundle.html savedInstanceState` | If non-null, this fragment is being re-constructed from a previous saved state as given here. |
### prepareEntranceTransition
Added in [1.1.0](https://developer.android.com/jetpack/androidx/releases/leanback#1.1.0)
```
public void prepareEntranceTransition()
```
Enables entrance transition.
Entrance transition is the standard slide-in transition that shows rows of data in browse screen and details screen.
The method is ignored before LOLLIPOP (API21).
This method must be called in or before onCreate(). Typically entrance transition should be enabled when savedInstance is null so that fragment restored from instanceState does not run an extra entrance transition. When the entrance transition is enabled, the fragment will make headers and content hidden initially. When data of rows are ready, app must call `https://developer.android.com/reference/androidx/leanback/app/BaseSupportFragment#startEntranceTransition()` to kick off the transition, otherwise the rows will be invisible forever.
It is similar to android:windowsEnterTransition and can be considered a late-executed android:windowsEnterTransition controlled by app. There are two reasons that app needs it:
- Workaround the problem that activity transition is not available between launcher and app. Browse activity must programmatically start the slide-in transition.
- Separates DetailsOverviewRow transition from other rows transition. So that the DetailsOverviewRow transition can be executed earlier without waiting for all rows to be loaded.
Transition object is returned by createEntranceTransition(). Typically the app does not need override the default transition that browse and details provides.
### startEntranceTransition
Added in [1.1.0](https://developer.android.com/jetpack/androidx/releases/leanback#1.1.0)
```
public void startEntranceTransition()
```
When fragment finishes loading data, it should call startEntranceTransition() to execute the entrance transition. startEntranceTransition() will start transition only if both two conditions are satisfied:
- prepareEntranceTransition() was called.
- has not executed entrance transition yet.
If startEntranceTransition() is called before onViewCreated(), it will be pending and executed when view is created.
## Protected methods
### createEntranceTransition
Added in [1.1.0](https://developer.android.com/jetpack/androidx/releases/leanback#1.1.0)
```
protected Object createEntranceTransition()
```
Create entrance transition. Subclass can override to load transition from resource or construct manually. Typically app does not need to override the default transition that browse and details provides.
### onEntranceTransitionEnd
Added in [1.1.0](https://developer.android.com/jetpack/androidx/releases/leanback#1.1.0)
```
protected void onEntranceTransitionEnd()
```
Callback when entrance transition is ended.
### onEntranceTransitionPrepare
Added in [1.1.0](https://developer.android.com/jetpack/androidx/releases/leanback#1.1.0)
```
protected void onEntranceTransitionPrepare()
```
Callback when entrance transition is prepared. This is when fragment should stop user input and animations.
### onEntranceTransitionStart
Added in [1.1.0](https://developer.android.com/jetpack/androidx/releases/leanback#1.1.0)
```
protected void onEntranceTransitionStart()
```
Callback when entrance transition is started. This is when fragment should stop processing layout.
### runEntranceTransition
Added in [1.1.0](https://developer.android.com/jetpack/androidx/releases/leanback#1.1.0)
```
protected void runEntranceTransition(Object entranceTransition)
```
Run entrance transition. Subclass may use TransitionManager to perform go(Scene) or beginDelayedTransition(). App should not override the default implementation of browse and details fragment.
