こんにちは。前のセクションでは分割画面の起動プロセスを分析しました。このセクションでは、分割画面の使用中に分割線をドラッグするプロセスを紹介します。
1. 分割線のドラッグ部分
B局無料動画チュートリアル解説：
https://www.bilibili.com/video/BV1wj411o7A9/
ドラッグした分割線のDividerViewのonTouchを見てください
public boolean onTouch(View v, MotionEvent event) {
if (mSplitLayout == null || !mInteractive) {
return false;
}
if (mDoubleTapDetector.onTouchEvent(event)) {
return true;
}
// Convert to use screen-based coordinates to prevent lost track of motion events while
// moving divider bar and calculating dragging velocity.
event.setLocation(event.getRawX(), event.getRawY());
final int action = event.getAction() & MotionEvent.ACTION_MASK;
final boolean isLandscape = isLandscape();
final int touchPos = (int) (isLandscape ? event.getX() : event.getY());
switch (action) {
case MotionEvent.ACTION_DOWN:
mVelocityTracker = VelocityTracker.obtain();
mVelocityTracker.addMovement(event);
setTouching();
mStartPos = touchPos;
mMoving = false;
break;
case MotionEvent.ACTION_MOVE:
mVelocityTracker.addMovement(event);
if (!mMoving && Math.abs(touchPos - mStartPos) > mTouchSlop) {
mStartPos = touchPos;
mMoving = true;
}
if (mMoving) {
final int position = mSplitLayout.getDividePosition() + touchPos - mStartPos;
mSplitLayout.updateDivideBounds(position);//最重要的拖动方法
}
break;
case MotionEvent.ACTION_UP:
case MotionEvent.ACTION_CANCEL:
releaseTouching();
if (!mMoving) break;
mVelocityTracker.addMovement(event);
mVelocityTracker.computeCurrentVelocity(1000 /* units */);
final float velocity = isLandscape
? mVelocityTracker.getXVelocity()
: mVelocityTracker.getYVelocity();
final int position = mSplitLayout.getDividePosition() + touchPos - mStartPos;
final DividerSnapAlgorithm.SnapTarget snapTarget =
mSplitLayout.findSnapTarget(position, velocity, false /* hardDismiss */);
mSplitLayout.snapToTarget(position, snapTarget);//松手后要进行动画，DividerView自动到某个区域
mMoving = false;
break;
}
return true;
}
ここでは、mSplitLayout.updateDivideBounds(position) メソッドに焦点を当てます。
/**
* Updates bounds with the passing position. Usually used to update recording bounds while
* performing animation or dragging divider bar to resize the splits.
*/
void updateDivideBounds(int position) {
updateBounds(position);//更新一下bound区域
mSplitLayoutHandler.onLayoutSizeChanging(this);
//会调用对应的onLayoutSizeChanging方法来负责通知size变化了
}
@Override
public void onLayoutSizeChanging(SplitLayout layout) {
final SurfaceControl.Transaction t = mTransactionPool.acquire();
t.setFrameTimelineVsync(Choreographer.getInstance().getVsyncId());
setResizingSplits(true /* resizing */);
updateSurfaceBounds(layout, t, true /* applyResizingOffset */);//会把对应的DividerView进行坐标更新，实现跟手
mMainStage.onResizing(getMainStageBounds(), t);//通知主屏幕，告知有size变化，如果bounds变大则显示icon+背景，否则显示原来内容，并控制内容的区域跟随divideriew位置
mSideStage.onResizing(getSideStageBounds(), t);//通知次屏幕，告知有size变化，如果bounds变大则显示icon+背景，否则显示原来内容，并控制内容的区域跟随divideriew位置
t.apply();
mTransactionPool.release(t);
}
void updateSurfaceBounds(@Nullable SplitLayout layout, @NonNull SurfaceControl.Transaction t,
boolean applyResizingOffset) {
final StageTaskListener topLeftStage =
mSideStagePosition == SPLIT_POSITION_TOP_OR_LEFT ? mSideStage : mMainStage;
final StageTaskListener bottomRightStage =
mSideStagePosition == SPLIT_POSITION_TOP_OR_LEFT ? mMainStage : mSideStage;
//这里关键调用了applySurfaceChanges
(layout != null ? layout : mSplitLayout).applySurfaceChanges(t, topLeftStage.mRootLeash,
bottomRightStage.mRootLeash, topLeftStage.mDimLayer, bottomRightStage.mDimLayer,
applyResizingOffset);
}
applySurfaceChanges メソッドを見てみましょう。
public void applySurfaceChanges(SurfaceControl.Transaction t, SurfaceControl leash1,
SurfaceControl leash2, SurfaceControl dimLayer1, SurfaceControl dimLayer2,
boolean applyResizingOffset) {
final SurfaceControl dividerLeash = getDividerLeash();
if (dividerLeash != null) {
mTempRect.set(getRefDividerBounds());
t.setPosition(dividerLeash, mTempRect.left, mTempRect.top);
//这里是设置DeviderView进行位置设置
// Resets layer of divider bar to make sure it is always on top.
t.setLayer(dividerLeash, Integer.MAX_VALUE);
}
mTempRect.set(getRefBounds1());
t.setPosition(leash1, mTempRect.left, mTempRect.top)//设置上下分屏的位置和裁减
.setWindowCrop(leash1, mTempRect.width(), mTempRect.height());
mTempRect.set(getRefBounds2());
t.setPosition(leash2, mTempRect.left, mTempRect.top)
.setWindowCrop(leash2, mTempRect.width(), mTempRect.height());
if (mImePositionProcessor.adjustSurfaceLayoutForIme(
t, dividerLeash, leash1, leash2, dimLayer1, dimLayer2)) {
return;
}
mSurfaceEffectPolicy.adjustDimSurface(t, dimLayer1, dimLayer2);//进行对应的特效显示，拉到底部或之顶部进行灰度提示
if (applyResizingOffset) {
mSurfaceEffectPolicy.adjustRootSurface(t, leash1, leash2);
}
}
次に、mMainStage.onResizing メソッドを確認します。
/** Showing resizing hint. */
public void onResizing(ActivityManager.RunningTaskInfo resizingTask, Rect newBounds,
SurfaceControl.Transaction t) {
//省略
//这里本质就是判断是否该区域有变大，如果有变大则变成ICON+背景，另一个屏则保持原样，因为show是为false
final boolean show =
newBounds.width() > mBounds.width() || newBounds.height() > mBounds.height();
//省略
t.setPosition(mIconLeash,
newBounds.width() / 2 - mIconSize / 2,
newBounds.height() / 2 - mIconSize / 2);
if (animate) {
//启动相关显示的动画
startFadeAnimation(show, false /* isResized */);
mShown = show;
}
}

2. 手を離した後の移動アニメーションとタスクの領域設定
上記ですでに知られているように、これは主に、手放した後に mSplitLayout.snapToTarget(position, snapTarget) によって実行されます。
/**
* Sets new divide position and updates bounds correspondingly. Notifies listener if the new
* target indicates dismissing split.
*/
public void snapToTarget(int currentPosition, DividerSnapAlgorithm.SnapTarget snapTarget) {
switch (snapTarget.flag) {
case FLAG_DISMISS_START:
flingDividePosition(currentPosition, snapTarget.position,
() -> mSplitLayoutHandler.onSnappedToDismiss(false /* bottomOrRight */));
break;
case FLAG_DISMISS_END:
flingDividePosition(currentPosition, snapTarget.position,
() -> mSplitLayoutHandler.onSnappedToDismiss(true /* bottomOrRight */));
break;
default:
flingDividePosition(currentPosition, snapTarget.position,
() -> setDividePosition(snapTarget.position, true /* applyLayoutChange */));
break;
}
}
ここで FLAG_DISMISS_START と FLAG_DISMISS_END について説明します。
FLAG_DISMISS_START: 以下の図に示すように、DividerView が上にスライドし、上部の分割画面が終了することを意味します。
FLAG_DISMISS_END: 次の分割画面がシーンから出るまで下にスライドすることを表します
多くの状況があることがわかりますが、それらはすべて flingDividePosition を呼び出しますが、最終的なコールバック メソッドは異なります。ここでは通常、デフォルトの状況を使用します。
@VisibleForTesting
void flingDividePosition(int from, int to, @Nullable Runnable flingFinishedCallback) {
if (from == to) {
// No animation run, still callback to stop resizing.
mSplitLayoutHandler.onLayoutSizeChanged(this);
return;
}
InteractionJankMonitorUtils.beginTracing(InteractionJankMonitor.CUJ_SPLIT_SCREEN_RESIZE,
mSplitWindowManager.getDividerView(), "Divider fling");
ValueAnimator animator = ValueAnimator
.ofInt(from, to)
.setDuration(250);//开始设置动画，一个from一个to作为开始和截至地方
animator.setInterpolator(Interpolators.FAST_OUT_SLOW_IN);
animator.addUpdateListener(
animation -> updateDivideBounds((int) animation.getAnimatedValue()));
animator.addListener(new AnimatorListenerAdapter() {
@Override
public void onAnimationEnd(Animator animation) {
//动画结束以后的最重要的操作，需要真正的windowcontainer的bounds进行操作了
if (flingFinishedCallback != null) {
flingFinishedCallback.run();//执行传递进来的那个runable
}
InteractionJankMonitorUtils.endTracing(
InteractionJankMonitor.CUJ_SPLIT_SCREEN_RESIZE);
}
@Override
public void onAnimationCancel(Animator animation) {
setDividePosition(to, true /* applyLayoutChange */);
}
});
animator.start();
}
ここでの重要なポイントは、アニメーションの実行が完了した後に setDividePosition メソッドを呼び出すことです。
void setDividePosition(int position, boolean applyLayoutChange) {
mDividePosition = position;
updateBounds(mDividePosition);
if (applyLayoutChange) {
mSplitLayoutHandler.onLayoutSizeChanged(this);
}
}
この setDividePosition についてはhttps://blog.csdn.net/learnframework/article/details/130944230で説明されており
、最後に対応する境界が systemserver のタスクに設定されます。
3. systemserver の終了原理
systemui 側の呼び出し状況を確認してください。
フレームワーク/base/libs/WindowManager/Shell/src/com/android/wm/shell/splitscreen/StageCoordinator.java
private void applyExitSplitScreen(@Nullable StageTaskListener childrenToTop,
WindowContainerTransaction wct, @ExitReason int exitReason) {
//省略
final boolean fromEnteringPip = exitReason == EXIT_REASON_CHILD_TASK_ENTER_PIP;
mSideStage.removeAllTasks(wct, !fromEnteringPip && mSideStage == childrenToTop);//移除对应的sidestate下面task节点,其实本质就是把子节点进行对应的reparent到新的父亲
mMainStage.deactivate(wct, !fromEnteringPip && mMainStage == childrenToTop);//其实和上面的removeAllTask类似，都是对task进行reparent操作，不能再继续挂载在分屏的节点了
//对分屏的总节点进行对应的reorder，放到后面了，不能到最前啦
wct.reorder(mRootTaskInfo.token, false /* onTop */);
mTaskOrganizer.applyTransaction(wct);
mSyncQueue.runInSync(t -> {
setResizingSplits(false /* resizing */);
t.setWindowCrop(mMainStage.mRootLeash, null)
.setWindowCrop(mSideStage.mRootLeash, null);
setDividerVisibility(false, t);
});
//省略
}
対応する mSideStage.removeAllTasks メソッドを見てください。
boolean removeAllTasks(WindowContainerTransaction wct, boolean toTop) {
if (mChildrenTaskInfo.size() == 0) return false;
wct.reparentTasks(
mRootTaskInfo.token,
null /* newParent */,
CONTROLLED_WINDOWING_MODES_WHEN_ACTIVE,
CONTROLLED_ACTIVITY_TYPES,
toTop);
return true;
}
reparentTasks と呼ばれる、reparentTasks Frameworks/base/core/java/android/window/WindowContainerTransaction.javaを見てみましょう。
public WindowContainerTransaction reparentTasks(@Nullable WindowContainerToken currentParent,
@Nullable WindowContainerToken newParent, @Nullable int[] windowingModes,
@Nullable int[] activityTypes, boolean onTop, boolean reparentTopOnly) {
mHierarchyOps.add(HierarchyOp.createForChildrenTasksReparent(
currentParent != null ? currentParent.asBinder() : null,
newParent != null ? newParent.asBinder() : null,
windowingModes,
activityTypes,
onTop,
reparentTopOnly));
return this;
}
//创建对应HIERARCHY_OP_TYPE_CHILDREN_TASKS_REPARENT的HierarchyOp
public static HierarchyOp createForChildrenTasksReparent(IBinder currentParent,
IBinder newParent, int[] windowingModes, int[] activityTypes, boolean onTop,
boolean reparentTopOnly) {
return new HierarchyOp.Builder(HIERARCHY_OP_TYPE_CHILDREN_TASKS_REPARENT)
.setContainer(currentParent)
.setReparentContainer(newParent)
.setWindowingModes(windowingModes)
.setActivityTypes(activityTypes)
.setToTop(onTop)
.setReparentTopOnly(reparentTopOnly)
.build();
}
この時点で、systemui 部分の終了操作が完了します。
システムサーバー側の呼び出しを確認してください。
Frameworks/base/services/core/java/com/android/server/wm/WindowOrganizerController.java
private int applyHierarchyOp(WindowContainerTransaction.HierarchyOp hop, int effects,
int syncId, @Nullable Transition transition, boolean isInLockTaskMode,
@NonNull CallerInfo caller, @Nullable IBinder errorCallbackToken,
@Nullable ITaskFragmentOrganizer organizer, @Nullable Transition finishTransition) {
//省略
switch (type) {
case HIERARCHY_OP_TYPE_CHILDREN_TASKS_REPARENT: {
//核心方法
effects |= reparentChildrenTasksHierarchyOp(hop, transition, syncId);
break;
}
//省略
}
コアメソッド reparentChildrenTasksHierarchyOp がここで呼び出されます
private int reparentChildrenTasksHierarchyOp(WindowContainerTransaction.HierarchyOp hop,
@Nullable Transition transition, int syncId) {
WindowContainer<?> currentParent = hop.getContainer() != null
? WindowContainer.fromBinder(hop.getContainer()) : null;
WindowContainer newParent = hop.getNewParent() != null
? WindowContainer.fromBinder(hop.getNewParent()) : null;
if (currentParent == null && newParent == null) {
//省略
} else if (newParent == null) {
//这里传递为null，所以给予没人的parent为DefaultTaskDisplayArea
newParent = currentParent.asTask().getDisplayContent().getDefaultTaskDisplayArea();
}
//省略
final ArrayList<Task> tasksToReparent = new ArrayList<>();
//对当前的task节点下面所有children进行遍历
currentParent.forAllTasks(task -> {
final boolean reparent;
//注意这里的话可能activitytype和windowmode不支持，就要直接返回不会放入tasksToReparent
if (!ArrayUtils.contains(hop.getActivityTypes(), task.getActivityType())
|| !ArrayUtils.contains(hop.getWindowingModes(), task.getWindowingMode())) {
return false;
}
//如果放到顶部的就放到
if (hop.getToTop()) {
tasksToReparent.add(0, task);
} else {
tasksToReparent.add(task);
}
return hop.getReparentTopOnly() && tasksToReparent.size() == 1;
});
final int count = tasksToReparent.size();
for (int i = 0; i < count; ++i) {
final Task task = tasksToReparent.get(i);
//省略
//刚好这里newParent就是TaskDisplayArea，即直接把原理挂在上下分屏的task挂到TaskDisplayArea下面
if (newParent instanceof TaskDisplayArea) {
// For now, reparenting to display area is different from other reparents...
task.reparent((TaskDisplayArea) newParent, hop.getToTop());
} else {
task.reparent((Task) newParent,
hop.getToTop() ? POSITION_TOP : POSITION_BOTTOM,
false /*moveParents*/, "processChildrenTaskReparentHierarchyOp");
}
}
return TRANSACT_EFFECTS_LIFECYCLE;
}
このようにして、分割画面全体が終了し、コアプロセスが完了します。ライフサイクルの変更をトリガーするには、残りをresumeToActivityとensureVisibleActivityに関連付ける必要があります。
該当分割線の該当位置の初期化処理を補足します 位置は上、下、中、上半分、下半分の合計5箇所あります 作成処理は以下の通りです
