WindowInsets

简单整理一下 window insets 的 日志添加，大部分都是加在方法入口，捋一下大概的过程，Android14，给安卓小白的自己使用。

1. core/java/android/view/InsetsController.java

public void onControlsChanged(InsetsSourceControl[] activeControls);

public void show(@InsetsType int types, boolean fromIme, @Nullable ImeTracker.Token statsToken);

public void hide(@InsetsType int types, boolean fromIme, @Nullable ImeTracker.Token statsToken);

public void applyAnimation(@InsetsType final int types, boolean show, boolean fromIme, boolean skipAnim, @Nullable ImeTracker.Token statsToken);

2. core/java/android/view/InsetsSourceControl.java

public InsetsSourceControl(int id, @InsetsType int type, @Nullable SurfaceControl leash, boolean initiallyVisible, Point surfacePosition, Insets insetsHint);

public void release(Consumer<SurfaceControl> surfaceReleaseConsumer);

3. services/core/java/com/android/server/wm/DisplayPolicy.java

void addWindowLw(WindowState win, WindowManager.LayoutParams attrs){
    ... ...
    /* 添加了一些日志 */
    mDisplayContent.getInsetsStateController().getOrCreateSourceProvider(    provider.getId(), provider.getType()).setWindowContainer(win, frameProvider, overrideProviders);
    mInsetsSourceWindowsExceptIme.add(win);
}

void removeWindowLw(WindowState win);

4. services/core/java/com/android/server/wm/InsetsSourceProvider.java

InsetsSourceProvider(InsetsSource source, InsetsStateController stateController, DisplayContent displayContent);

void updateFakeControlTarget(@Nullable InsetsControlTarget fakeTarget);

void updateControlForTarget(@Nullable InsetsControlTarget target, boolean force){
    ... ...
    final SurfaceControl leash = mAdapter.mCapturedLeash;
    if (mControllable){
        /* 加了一些日志 */
    }
    
}

void onSurfaceTransactionApplied();

void setClientVisible(boolean clientVisible);

void setServerVisible(boolean serverVisible);

protected void updateVisibility();

public void startAnimation(SurfaceControl animationLeash, Transaction t,
    @AnimationType int type, @NonNull OnAnimationFinishedCallback finishCallback);
    
public void onAnimationCancelled(SurfaceControl animationLeash);

5. services/core/java/com/android/server/wm/InsetsStateController.java

InsetsSourceProvider getOrCreateSourceProvider(int id, @InsetsType int type){
    ... ...
    provider = id == ID_IME ? new ImeInsetsSourceProvider(source, this, mDisplayContent)
                        : new InsetsSourceProvider(source, this, mDisplayContent);
    /* 添加了一些日志 */
    mProviders.put(id, provider);
    return provider;
}

void removeSourceProvider(int id);

void onRequestedVisibleTypesChanged(InsetsControlTarget caller); /* 这个方法在谷歌源码里面没找到，有点奇怪 */

void notifyControlChanged(InsetsControlTarget target);

6. services/core/java/com/android/server/wm/SurfaceAnimator.java

static SurfaceControl createAnimationLeash(Animatable animatable, SurfaceControl surface,
    Transaction t, @AnimationType int type, int width, int height, int x, int y,
    boolean hidden, Supplier<Transaction> transactionFactory){
       /* 打印 type = ANIMATION_TYPE_INSETS_CONTROL */
       ... ...
}

7. services/core/java/com/android/server/wm/WindowManagerService.java

public int addWindow(Session session, IWindow client, LayoutParams attrs, int viewVisibility,
    int displayId, int requestUserId, @InsetsType int requestedVisibleTypes,
    InputChannel outInputChannel, InsetsState outInsetsState,
    InsetsSourceControl.Array outActiveControls, Rect outAttachedFrame,
    float[] outSizeCompatScale){
        WindowState parentWindow = null;
        final int callingUid = Binder.getCallingUid();
        final int callingPid = Binder.getCallingPid();
        final long origId = Binder.clearCallingIdentity();
        final int type = attrs.type;
        /* 加了一些日志打印 */
        synchronized (mGlobalLock) {
            ... ...
        }
        /* 加了一些日志打印 */
        boolean needToSendNewConfiguration =
            win.isVisibleRequestedOrAdding() && displayContent.updateOrientation();
        ... ...
}

8. services/core/java/com/android/server/wm/WindowState.java

void setRequestedVisibleTypes(@InsetsType int requestedVisibleTypes);
