ActivityThread#handleResumeActivity
Activity启动时一开始都是置为不可见INVISIBLE的然后才置为可见VISIBLE。ActivityThread.java - OpenGrok cross reference for /frameworks/base/core/java/android/app/ActivityThread.java Overridepublic void handleResumeActivity(ActivityClientRecord r, boolean finalStateRequest,boolean isForward, boolean shouldSendCompatFakeFocus, String reason) {// If we are getting ready to gc after going to the background, well// we are back active so skip it.unscheduleGcIdler();mSomeActivitiesChanged true;// TODO Push resumeArgs into the activity for consideration// skip below steps for double-resume and r.mFinish true case.
//这个是activity resume很重要的一步会调用到activity本身的onResume方法后面会做详细解释if (!performResumeActivity(r, finalStateRequest, reason)) {return;}
//如果mActivitiesToBeDestroyed集合包含此acitivity,则不往下执行resume操作。
//mActivitiesToBeDestroyed是即将 要销毁的activity集合if (mActivitiesToBeDestroyed.containsKey(r.token)) {// Although the activity is resumed, it is going to be destroyed. So the following// UI operations are unnecessary and also prevents exception because its token may// be gone that window manager cannot recognize it. All necessary cleanup actions// performed below will be done while handling destruction.return;}final Activity a r.activity;if (localLOGV) {Slog.v(TAG, Resume r started activity: a.mStartedActivity , hideForNow: r.hideForNow , finished: a.mFinished);}
...
//如果这个window没有被add进window manager并且这个activity没有执行finish操作或者启动其他activity则首先要将此window添加进window manager中。boolean willBeVisible !a.mStartedActivity;if (!willBeVisible) {willBeVisible ActivityClient.getInstance().willActivityBeVisible(a.getActivityToken());}
//这里代表这是首次启动这个activity
//如果window为空并且不要执行finish并且申请可见则进入如下逻辑if (r.window null !a.mFinished willBeVisible) {r.window r.activity.getWindow();View decor r.window.getDecorView();

...} 这块大概的流程图如上所示,在执行handleResumeActivity的时候会先去执行activity的onResume方法然后再将当前的window add进window manager。
这块有个地方拓展下就是窗口类型普通apk启动的窗口类型都是TYPE_BASE_APPLICATION l.type WindowManager.LayoutParams.TYPE_BASE_APPLICATION; Android系统三大窗口类型

本小节介绍了activity启动过程中其他的知识下文再继续接着讲怎么添加窗口流程的下面接着1.1中的addView方法。
2. WindowManager#addView
wm的获取方法如下可以看到最后是获得到了一个WindowManager对象 private WindowManager mWindowManager;public WindowManager getWindowManager() {return mWindowManager;} 那就来到了WindowManager中的addView方法
查看WindowManager中没有addView方法但是ViewManager中有那我们再看下谁实现了WindowManager呢 public interface WindowManager extends ViewManager {
-------------------------------------------------------------
public interface ViewManager
{public void addView(View view, ViewGroup.LayoutParams params);public void updateViewLayout(View view, ViewGroup.LayoutParams params);public void removeView(View view);
} 可找到是WindowManagerImpl中实现此addView方法,因为WindowManagerImpl继承了WindowManager
/** see WindowManager* see WindowManagerGlobal* hide*/
public final class WindowManagerImpl implements WindowManager {
...Overridepublic void addView(NonNull View view, NonNull ViewGroup.LayoutParams params) {applyTokens(params);mGlobal.addView(view, params, mContext.getDisplayNoVerify(), mParentWindow,mContext.getUserId());}
此方法又调用了 WindowManagerGlobal中的addView方法并将view窗口属性要显示的屏幕父window以及user id传入
WindowManagerGlobal.java - OpenGrok cross reference for /frameworks/base/core/java/android/view/WindowManagerGlobal.java public void addView(View view, ViewGroup.LayoutParams params,Display display, Window parentWindow, int userId) {if (view null) {throw new IllegalArgumentException(view must not be null);}if (display null) {throw new IllegalArgumentException(display must not be null);}if (!(params instanceof WindowManager.LayoutParams)) {throw new IllegalArgumentException(Params must be WindowManager.LayoutParams);}
//获取窗口布局属性final WindowManager.LayoutParams wparams (WindowManager.LayoutParams) params;if (parentWindow ! null) {
//如果父窗口不为空则调整当前父窗口下所有子窗口布局的属性parentWindow.adjustLayoutParamsForSubWindow(wparams);} else {// If theres no parent, then hardware acceleration for this view is// set from the applications hardware acceleration setting.final Context context view.getContext();if (context ! null (context.getApplicationInfo().flags ApplicationInfo.FLAG_HARDWARE_ACCELERATED) ! 0) {wparams.flags | WindowManager.LayoutParams.FLAG_HARDWARE_ACCELERATED;}}ViewRootImpl root;View panelParentView null;synchronized (mLock) {// Start watching for system property changes.if (mSystemPropertyUpdater null) {mSystemPropertyUpdater new Runnable() {Override public void run() {synchronized (mLock) {for (int i mRoots.size() - 1; i 0; --i) {mRoots.get(i).loadSystemProperties();}}}};SystemProperties.addChangeCallback(mSystemPropertyUpdater);}int index findViewLocked(view, false);if (index 0) {if (mDyingViews.contains(view)) {// Dont wait for MSG_DIE to make its way through roots queue.mRoots.get(index).doDie();} else {throw new IllegalStateException(View view has already been added to the window manager.);}// The previous removeView() had not completed executing. Now it has.}// If this is a panel window, then find the window it is being// attached to for future reference.
//如果是子窗口if (wparams.type WindowManager.LayoutParams.FIRST_SUB_WINDOW wparams.type WindowManager.LayoutParams.LAST_SUB_WINDOW) {final int count mViews.size();for (int i 0; i count; i) {if (mRoots.get(i).mWindow.asBinder() wparams.token) {panelParentView mViews.get(i);}}}IWindowSession windowlessSession null;// If there is a parent set, but we cant find it, it may be coming// from a SurfaceControlViewHost hierarchy.
//如果token不为空并且不是子窗口if (wparams.token ! null panelParentView null) {for (int i 0; i mWindowlessRoots.size(); i) {ViewRootImpl maybeParent mWindowlessRoots.get(i);if (maybeParent.getWindowToken() wparams.token) {
//获取WindowSessionwindowlessSession maybeParent.getWindowSession();break;}}}if (windowlessSession null) {
//如果windowlessSession为空root new ViewRootImpl(view.getContext(), display);} else {
//如果windowlessSession不为空则在此处传入windowlessSessionroot new ViewRootImpl(view.getContext(), display,windowlessSession, new WindowlessWindowLayout());}
//将窗口布局属性设置进viewview.setLayoutParams(wparams);
//将此view添加进mViewsmViews.add(view);
//将此root添加进MRootsmRoots.add(root);
//将此窗口布局属性添加进mParamsmParams.add(wparams);// do this last because it fires off messages to start doing thingstry {
//将view窗口属性和子窗口user id 设置进ViewRootImplroot.setView(view, wparams, panelParentView, userId);} catch (RuntimeException e) {final int viewIndex (index 0) ? index : (mViews.size() - 1);// BadTokenException or InvalidDisplayException, clean up.if (viewIndex 0) {removeViewLocked(viewIndex, true);}throw e;}}}3. ViewRootImpl#setView
然后就从WindowManagerGlobal走到了ViewRootImpl中
http://aospxref.com/android-14.0.0_r2/xref/frameworks/base/core/java/android/view/ViewRootImpl.java#1214 final IWindowSession mWindowSession;public void setView(View view, WindowManager.LayoutParams attrs, View panelParentView) {setView(view, attrs, panelParentView, UserHandle.myUserId());}public void setView(View view, WindowManager.LayoutParams attrs, View panelParentView, int userId) {synchronized (this) {
//这个mView和上一个方法中的可不一样当窗口detach后这个mView会被置为空if (mView null) {mView view;
...mWindowAttributes.copyFrom(attrs)
...// Schedule the first layout -before- adding to the window// manager, to make sure we do the relayout before receiving// any other events from the system.
//首先需要layoutrequestLayout();
...
//这个是很重要的一步res mWindowSession.addToDisplayAsUser(mWindow, mWindowAttributes,getHostVisibility(), mDisplay.getDisplayId(), userId,mInsetsController.getRequestedVisibleTypes(), inputChannel, mTempInsets, mTempControls, attachedFrame, compatScale);
...mPendingAlwaysConsumeSystemBars mAttachInfo.mAlwaysConsumeSystemBars;mInsetsController.onStateChanged(mTempInsets);mInsetsController.onControlsChanged(mTempControls.get());final InsetsState state mInsetsController.getState();final Rect displayCutoutSafe mTempRect;state.getDisplayCutoutSafe(displayCutoutSafe);final WindowConfiguration winConfig getCompatWindowConfiguration();mWindowLayout.computeFrames(mWindowAttributes, state,displayCutoutSafe, winConfig.getBounds(), winConfig.getWindowingMode(),UNSPECIFIED_LENGTH, UNSPECIFIED_LENGTH,mInsetsController.getRequestedVisibleTypes(), 1f /* compactScale */, mTmpFrames);setFrame(mTmpFrames.frame, true /* withinRelayout */);
...}
接着往下走就会讲到WindowSession.addToDisplayAsUser方法
4. WindowSession.addToDisplayAsUser
这里是涉及到AIDL通信因为mWindowSession是final IWindowSession mWindowSession;
用到的AIDL文件如下
frameworks/base/core/java/android/view/IWindowSession.aidl
http://aospxref.com/android-14.0.0_r2/xref/frameworks/base/core/java/android/view/IWindowSession.aidl
Session.java - OpenGrok cross reference for /frameworks/base/services/core/java/com/android/server/wm/Session.java Overridepublic int addToDisplayAsUser(IWindow window, WindowManager.LayoutParams attrs,int viewVisibility, int displayId, int userId, InsetsType int requestedVisibleTypes,InputChannel outInputChannel, InsetsState outInsetsState,InsetsSourceControl.Array outActiveControls, Rect outAttachedFrame,float[] outSizeCompatScale) {
//调用WMS的addWindow流程return mService.addWindow(this, window, attrs, viewVisibility, displayId, userId,requestedVisibleTypes, outInputChannel, outInsetsState, outActiveControls,outAttachedFrame, outSizeCompatScale);}
