NavHostFragment provides an area within your layout for self-contained navigation to occur.

NavHostFragment is intended to be used as the content area within a layout resource defining your app's chrome around it, e.g.:

```
<androidx.drawerlayout.widget.DrawerLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <androidx.fragment.app.FragmentContainerView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:id="@+id/my_nav_host_fragment"
        android:name="androidx.navigation.fragment.NavHostFragment"
        app:navGraph="@navigation/nav_sample"
        app:defaultNavHost="true" />

    <com.google.android.material.navigation.NavigationView
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="start"/>;
</androidx.drawerlayout.widget.DrawerLayout>
```

Each NavHostFragment has a `https://developer.android.com/reference/androidx/navigation/NavController` that defines valid navigation within the navigation host. This includes the `https://developer.android.com/reference/androidx/navigation/NavGraph` as well as navigation state such as current location and back stack that will be saved and restored along with the NavHostFragment itself.

NavHostFragments register their navigation controller at the root of their view subtree such that any descendant can obtain the controller instance through the `https://developer.android.com/reference/androidx/navigation/Navigation` helper class's methods such as `https://developer.android.com/reference/androidx/navigation/Navigation#findNavController(android.app.Activity,kotlin.Int)`. View event listener implementations such as `https://developer.android.com/reference/android/view/View.OnClickListener.html` within navigation destination fragments can use these helpers to navigate based on user interaction without creating a tight coupling to the navigation host.

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. |

### onCreateView

```
public View onCreateView(
    @NonNull LayoutInflater inflater,
    ViewGroup container,
    Bundle savedInstanceState
)
```

Called to have the fragment instantiate its user interface view. This is optional, and non-graphical fragments can return null. This will be called between `https://developer.android.com/reference/androidx/fragment/app/Fragment#onCreate(android.os.Bundle)` and `https://developer.android.com/reference/androidx/fragment/app/Fragment#onViewCreated(android.view.View,android.os.Bundle)`.

A default View can be returned by calling `https://developer.android.com/reference/androidx/fragment/app/Fragment#Fragment(int)` in your constructor. Otherwise, this method returns null.

It is recommended to **only** inflate the layout in this method and move logic that operates on the returned View to `https://developer.android.com/reference/androidx/fragment/app/Fragment#onViewCreated(android.view.View,android.os.Bundle)`.

If you return a View from here, you will later be called in `https://developer.android.com/reference/androidx/fragment/app/Fragment#onDestroyView()` when the view is being released.

| Parameters |
|---|---|
| `@https://developer.android.com/reference/androidx/annotation/NonNull https://developer.android.com/reference/android/view/LayoutInflater.html inflater` | The LayoutInflater object that can be used to inflate any views in the fragment, |
| `https://developer.android.com/reference/android/view/ViewGroup.html container` | If non-null, this is the parent view that the fragment's UI should be attached to. The fragment should not add the view itself, but this can be used to generate the LayoutParams of the view. |
| `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. |

| Returns |
|---|---|
| `https://developer.android.com/reference/android/view/View.html` | Return the View for the fragment's UI, or null. |

### 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.

### onInflate

```
@CallSuper
public void onInflate(
    @NonNull Context context,
    @NonNull AttributeSet attrs,
    Bundle savedInstanceState
)
```

Called when a fragment is being created as part of a view layout inflation, typically from setting the content view of an activity. This may be called immediately after the fragment is created from a `https://developer.android.com/reference/androidx/fragment/app/FragmentContainerView` in a layout file. Note this is *before* the fragment's `https://developer.android.com/reference/androidx/fragment/app/Fragment#onAttach(android.content.Context)` has been called; all you should do here is parse the attributes and save them away.

This is called *the first time* the fragment is inflated. If it is being inflated into a new instance with saved state, this method will not be called a second time for the restored state fragment.

Here is a typical implementation of a fragment that can take parameters both through attributes supplied here as well from `https://developer.android.com/reference/androidx/fragment/app/Fragment#getArguments()`:

```java
public static class MyFragment extends Fragment {
    CharSequence mLabel;

    /**
     * Create a new instance of MyFragment that will be initialized
     * with the given arguments.
     */
    static MyFragment newInstance(CharSequence label) {
        MyFragment f = new MyFragment();
        Bundle b = new Bundle();
        b.putCharSequence("label", label);
        f.setArguments(b);
        return f;
    }

    /**
     * Parse attributes during inflation from a view hierarchy into the
     * arguments we handle.
     */
    @Override
    public void onInflate(@NonNull Context context, @NonNull AttributeSet attrs,
            @Nullable Bundle savedInstanceState) {
        super.onInflate(context, attrs, savedInstanceState);

        TypedArray a = context.obtainStyledAttributes(attrs,
                R.styleable.FragmentArguments);
        mLabel = a.getText(R.styleable.FragmentArguments_android_label);
        a.recycle();
    }

    /**
     * During creation, if arguments have been supplied to the fragment
     * then parse those out.
     */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        Bundle args = getArguments();
        if (args != null) {
            CharSequence label = args.getCharSequence("label");
            if (label != null) {
                mLabel = label;
            }
        }
    }

    /**
     * Create the view for this fragment, using the arguments given to it.
     */
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        View v = inflater.inflate(R.layout.hello_world, container, false);
        View tv = v.findViewById(R.id.text);
        ((TextView)tv).setText(mLabel != null ? mLabel : "(no label)");
        ViewCompat.setBackground(
                tv, ContextCompat.getDrawable(getContext(), android.R.drawable.gallery_thumb));
        return v;
    }
}
```

Note that parsing the XML attributes uses a "styleable" resource. The declaration for the styleable used here is:

```xml
<declare-styleable name="FragmentArguments">
    <attr name="android:label" />
</declare-styleable>
```

The fragment can then be declared within its activity's content layout through a tag like this:

```xml
<androidx.fragment.app.FragmentContainerView
        class="com.example.android.supportv4.app.FragmentArgumentsSupport$MyFragment"
        android:id="@+id/embedded"
        android:layout_width="0px" android:layout_height="wrap_content"
        android:layout_weight="1"
        android:label="@string/fragment_arguments_embedded" />
```

This fragment can also be created dynamically from arguments given at runtime in the arguments Bundle; here is an example of doing so at creation of the containing activity:

```java
@Override protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.fragment_arguments_support);

    if (savedInstanceState == null) {
        // First-time init; create fragment to embed in activity.
        FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
        Fragment newFragment = MyFragment.newInstance("From Arguments");
        ft.add(R.id.created, newFragment);
        ft.commit();
    }
}
```

| Parameters |
|---|---|
| `@https://developer.android.com/reference/androidx/annotation/NonNull https://developer.android.com/reference/android/content/Context.html context` | The Activity that is inflating this fragment. |
| `@https://developer.android.com/reference/androidx/annotation/NonNull https://developer.android.com/reference/android/util/AttributeSet.html attrs` | The attributes at the tag where the fragment is being created. |
| `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. |

### onSaveInstanceState

```
@CallSuper
public void onSaveInstanceState(@NonNull Bundle outState)
```

Called to ask the fragment to save its current dynamic state, so it can later be reconstructed in a new instance if its process is restarted. If a new instance of the fragment later needs to be created, the data you place in the Bundle here will be available in the Bundle given to `https://developer.android.com/reference/androidx/fragment/app/Fragment#onCreate(android.os.Bundle)`, `https://developer.android.com/reference/androidx/fragment/app/Fragment#onCreateView(android.view.LayoutInflater,android.view.ViewGroup,android.os.Bundle)`, and `https://developer.android.com/reference/androidx/fragment/app/Fragment#onViewCreated(android.view.View,android.os.Bundle)`.

This corresponds to `https://developer.android.com/reference/android/app/Activity.html#onSaveInstanceState(android.os.Bundle)` and most of the discussion there applies here as well. Note however: *this method may be called at any time before `https://developer.android.com/reference/androidx/fragment/app/Fragment#onDestroy()`*. There are many situations where a fragment may be mostly torn down (such as when placed on the back stack with no UI showing), but its state will not be saved until its owning activity actually needs to save its state.

| Parameters |
|---|---|
| `@https://developer.android.com/reference/androidx/annotation/NonNull https://developer.android.com/reference/android/os/Bundle.html outState` | Bundle in which to place your saved state. |

### onViewCreated

```
public void onViewCreated(@NonNull View view, 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://developer.android.com/reference/androidx/annotation/NonNull 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://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. |
