*** ** * ** ***

A fragment supports adaptive two-pane layout. The first child is a list pane, which could be a content list or browser, and the second child is NavHostFragment which controls to navigate between different detail views.

Implementation of the fragment should override this class and implement `https://developer.android.com/reference/kotlin/androidx/navigation/fragment/AbstractListDetailFragment#onCreateListPaneView(android.view.LayoutInflater,android.view.ViewGroup,android.os.Bundle)` to supply custom view for the list pane. The fragment provides default `https://developer.android.com/reference/kotlin/androidx/navigation/fragment/NavHostFragment` with a NavGraph ID passed in the fragment, and it can be overridden by `https://developer.android.com/reference/kotlin/androidx/navigation/fragment/AbstractListDetailFragment#onCreateDetailPaneNavHostFragment()` and provide custom NavHostFragment.

### onInflate

```
@CallSuper
open fun onInflate(
    context: Context,
    attrs: AttributeSet,
    savedInstanceState: Bundle?
): Unit
```

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/kotlin/androidx/fragment/app/FragmentContainerView` in a layout file. Note this is *before* the fragment's `https://developer.android.com/reference/kotlin/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/kotlin/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 |
|---|---|
| `context: https://developer.android.com/reference/android/content/Context.html` | The Activity that is inflating this fragment. |
| `attrs: https://developer.android.com/reference/android/util/AttributeSet.html` | The attributes at the tag where the fragment is being created. |
| `savedInstanceState: https://developer.android.com/reference/android/os/Bundle.html?` | If the fragment is being re-created from a previous saved state, this is the state. |

### onListPaneViewCreated

Added in [2.4.0](https://developer.android.com/jetpack/androidx/releases/navigation#2.4.0)

```
open fun onListPaneViewCreated(view: View, savedInstanceState: Bundle?): Unit
```

Provides list pane view created in the fragment. Called when the fragment's `https://developer.android.com/reference/kotlin/androidx/navigation/fragment/AbstractListDetailFragment#onViewCreated(android.view.View,android.os.Bundle)` get called.

| Parameters |
|---|---|
| `view: https://developer.android.com/reference/android/view/View.html` | The list pane view created by `https://developer.android.com/reference/kotlin/androidx/navigation/fragment/AbstractListDetailFragment#onCreateListPaneView(android.view.LayoutInflater,android.view.ViewGroup,android.os.Bundle)` and added to view hierarchy |
| `savedInstanceState: https://developer.android.com/reference/android/os/Bundle.html?` | The previous saved state of the fragment. |

### onSaveInstanceState

```
@CallSuper
open fun onSaveInstanceState(outState: Bundle): Unit
```

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/kotlin/androidx/fragment/app/Fragment#onCreate(android.os.Bundle)`, `https://developer.android.com/reference/kotlin/androidx/fragment/app/Fragment#onCreateView(android.view.LayoutInflater,android.view.ViewGroup,android.os.Bundle)`, and `https://developer.android.com/reference/kotlin/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/kotlin/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 |
|---|---|
| `outState: https://developer.android.com/reference/android/os/Bundle.html` | Bundle in which to place your saved state. |

### onViewCreated

Added in [2.4.0](https://developer.android.com/jetpack/androidx/releases/navigation#2.4.0)

```
@CallSuper
final fun onViewCreated(view: View, savedInstanceState: Bundle?): Unit
```

This method provides a callback `https://developer.android.com/reference/kotlin/androidx/navigation/fragment/AbstractListDetailFragment#onListPaneViewCreated(android.view.View,android.os.Bundle)` after the view hierarchy has been completely created.

| Parameters |
|---|---|
| `view: https://developer.android.com/reference/android/view/View.html` | The view returned by `https://developer.android.com/reference/kotlin/androidx/navigation/fragment/AbstractListDetailFragment#onCreateView(android.view.LayoutInflater,android.view.ViewGroup,android.os.Bundle)` |
| `savedInstanceState: https://developer.android.com/reference/android/os/Bundle.html?` | The previous saved state of the fragment. |

| See also |
|---|---|
| `https://developer.android.com/reference/kotlin/androidx/navigation/fragment/AbstractListDetailFragment#onListPaneViewCreated(android.view.View,android.os.Bundle)` |   |

### onViewStateRestored

```
@CallSuper
open fun onViewStateRestored(savedInstanceState: Bundle?): Unit
```

Called when all saved state has been restored into the view hierarchy of the fragment. This can be used to do initialization based on saved state that you are letting the view hierarchy track itself, such as whether check box widgets are currently checked. This is called after `https://developer.android.com/reference/kotlin/androidx/fragment/app/Fragment#onViewCreated(android.view.View,android.os.Bundle)` and before `https://developer.android.com/reference/kotlin/androidx/fragment/app/Fragment#onStart()`.

| Parameters |
|---|---|
| `savedInstanceState: https://developer.android.com/reference/android/os/Bundle.html?` | If the fragment is being re-created from a previous saved state, this is the state. |
