ここで見つけるのは比較的簡単です。関数は onClick に応答し、次に HideMenu を開始します。これにより、次のようにコア コードを非表示にするアニメーションが開始されます:
Frameworks
/base/libs/WindowManager/Shell/src/com/android/ wm/shell/pip/phone/PipMenuView .java
void hideMenu(final Runnable animationFinishedRunnable, boolean notifyMenuVisibility,
boolean resize, @AnimationType int animationType) {
if (mMenuState != MENU_STATE_NONE) {
cancelDelayedHide();
if (notifyMenuVisibility) {
notifyMenuStateChangeStart(MENU_STATE_NONE, resize, null);
}
mMenuContainerAnimator = new AnimatorSet();
ObjectAnimator menuAnim = ObjectAnimator.ofFloat(mMenuContainer, View.ALPHA,
mMenuContainer.getAlpha(), 0f);
menuAnim.addUpdateListener(mMenuBgUpdateListener);
ObjectAnimator settingsAnim = ObjectAnimator.ofFloat(mSettingsButton, View.ALPHA,
mSettingsButton.getAlpha(), 0f);
ObjectAnimator dismissAnim = ObjectAnimator.ofFloat(mDismissButton, View.ALPHA,
mDismissButton.getAlpha(), 0f);
ObjectAnimator enterSplitAnim = ObjectAnimator.ofFloat(mEnterSplitButton, View.ALPHA,
mEnterSplitButton.getAlpha(), 0f);
mMenuContainerAnimator.playTogether(menuAnim, settingsAnim, dismissAnim,
enterSplitAnim);
mMenuContainerAnimator.setInterpolator(Interpolators.ALPHA_OUT);
mMenuContainerAnimator.setDuration(getFadeOutDuration(animationType));
mMenuContainerAnimator.addListener(new AnimatorListenerAdapter() {
@Override
public void onAnimationEnd(Animator animation) {
setVisibility(GONE);
if (notifyMenuVisibility) {
notifyMenuStateChangeFinish(MENU_STATE_NONE);
}
if (animationFinishedRunnable != null) {
animationFinishedRunnable.run();
}
}
});
mMenuContainerAnimator.start();
}
}
PipMenuView アニメーションが終了したら、対応する WindowMode と境界を設定し、小さなウィンドウのタスクに対してアニメーションのズームイン アクションを実行します。

コアコードは次のとおりです。
public void exitPip(int animationDurationMs, boolean requestEnterSplit) {
//省略
final Rect destinationBounds = getExitDestinationBounds();//获取目标大小，这里推出pip应该到全屏，所以destinationBounds为全屏
final int direction = syncWithSplitScreenBounds(destinationBounds, requestEnterSplit)
? TRANSITION_DIRECTION_LEAVE_PIP_TO_SPLIT_SCREEN
: TRANSITION_DIRECTION_LEAVE_PIP;
if (Transitions.ENABLE_SHELL_TRANSITIONS && direction ==
//省略
} else {
final SurfaceControl.Transaction tx =
mSurfaceControlTransactionFactory.getTransaction();
mSurfaceTransactionHelper.scale(tx, mLeash, destinationBounds,
mPipBoundsState.getBounds());
tx.setWindowCrop(mLeash, destinationBounds.width(), destinationBounds.height());
// We set to fullscreen here for now, but later it will be set to UNDEFINED for
// the proper windowing mode to take place. See #applyWindowingModeChangeOnExit.
wct.setActivityWindowingMode(mToken, WINDOWING_MODE_FULLSCREEN); //设置windowmode为full
wct.setBounds(mToken, destinationBounds);//设置目标大小为全屏了
wct.setBoundsChangeTransaction(mToken, tx);
}
mPipTransitionState.setTransitionState(PipTransitionState.EXITING_PIP);
mSyncTransactionQueue.queue(wct);
mSyncTransactionQueue.runInSync(t -> {
final Rect sourceHintRect = PipBoundsAlgorithm.getValidSourceHintRect(
mPictureInPictureParams, destinationBounds);
//进行对应的pip到全屏的task窗口动画开启
final PipAnimationController.PipTransitionAnimator<?> animator =
animateResizePip(mPipBoundsState.getBounds(), destinationBounds, sourceHintRect,direction, animationDurationMs, 0 /* startingAngle */);
});
}
