FragmentContainerView

public final class FragmentContainerView extends FrameLayout


FragmentContainerView is a customized Layout designed specifically for Fragments. It extends FrameLayout, so it can reliably handle Fragment Transactions, and it also has additional features to coordinate with fragment behavior.

FragmentContainerView should be used as the container for Fragments, commonly set in the xml layout of an activity, e.g.:

<androidx.fragment.app.FragmentContainerView
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/fragment_container_view"
android:layout_width="match_parent"
android:layout_height="match_parent">
</androidx.fragment.app.FragmentContainerView>

FragmentContainerView can also be used to add a Fragment by using the android:name attribute. FragmentContainerView will perform a one time operation that:

  1. Creates a new instance of the Fragment

  2. Calls Fragment.onInflate

  3. Executes a FragmentTransaction to add the Fragment to the appropriate FragmentManager

You can optionally include an android:tag which allows you to use FragmentManager.findFragmentByTag to retrieve the added Fragment.

<androidx.fragment.app.FragmentContainerView
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/fragment_container_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:name="com.example.MyFragment"
android:tag="my_tag">
</androidx.fragment.app.FragmentContainerView>

FragmentContainerView should not be used as a replacement for other ViewGroups (FrameLayout, LinearLayout, etc) outside of Fragment use cases.

FragmentContainerView will only allow views returned by a Fragment's Fragment.onCreateView. Attempting to add any other view will result in an IllegalStateException.

Layout animations and transitions are disabled for FragmentContainerView for APIs above 17. Otherwise, Animations should be done through FragmentTransaction.setCustomAnimations. If animateLayoutChanges is set to true or setLayoutTransition is called directly an UnsupportedOperationException will be thrown.

Fragments using exit animations are drawn before all others for FragmentContainerView. This ensures that exiting Fragments do not appear on top of the view.

Public constructors

FragmentContainerView

Added in 1.2.0
public FragmentContainerView(@NonNull Context context)

FragmentContainerView

Added in 1.2.0
public FragmentContainerView(
    @NonNull Context context,
    AttributeSet attrs,
    int defStyleAttr
)

Do not call this constructor directly. Doing so will result in an UnsupportedOperationException.

Public methods

addView

public void addView(@NonNull View child, int index, ViewGroup.LayoutParams params)

FragmentContainerView will only allow views returned by a Fragment's Fragment.onCreateView. Attempting to add any other view will result in an IllegalStateException.

{@inheritDoc}

dispatchApplyWindowInsets

@RequiresApi(value = 20)
public @NonNull WindowInsets dispatchApplyWindowInsets(@NonNull WindowInsets insets)

{@inheritDoc}

The sys ui flags must be set to enable extending the layout into the window insets.

endViewTransition

public void endViewTransition(@NonNull View view)

getFragment

Added in 1.4.0
public final @NonNull F <F extends Fragment> getFragment()

This method grabs the Fragment whose view was most recently added to the container. This may used as an alternative to calling FragmentManager.findFragmentById and passing in the FragmentContainerView's id.

Returns
@NonNull F

The fragment if any exist, null otherwise.

onApplyWindowInsets

@RequiresApi(value = 20)
public @NonNull WindowInsets onApplyWindowInsets(@NonNull WindowInsets insets)

removeAllViewsInLayout

public void removeAllViewsInLayout()

removeView

public void removeView(@NonNull View view)

removeViewAt

public void removeViewAt(int index)

removeViewInLayout

public void removeViewInLayout(@NonNull View view)

removeViews

public void removeViews(int start, int count)

removeViewsInLayout

public void removeViewsInLayout(int start, int count)

setLayoutTransition

public void setLayoutTransition(LayoutTransition transition)

When called, this method throws a UnsupportedOperationException on APIs above 17. On APIs 17 and below, it calls FrameLayout.setLayoutTransition. This can be called either explicitly, or implicitly by setting animateLayoutChanges to true.

View animations and transitions are disabled for FragmentContainerView for APIs above 17. Use FragmentTransaction.setCustomAnimations and FragmentTransaction.setTransition.

ref android.R.styleable#ViewGroup_animateLayoutChanges

Parameters
LayoutTransition transition

The LayoutTransition object that will animated changes in layout. A value of null means no transition will run on layout changes.

setOnApplyWindowInsetsListener

public void setOnApplyWindowInsetsListener(
    @NonNull View.OnApplyWindowInsetsListener listener
)

startViewTransition

public void startViewTransition(@NonNull View view)

Protected methods
