SystemServer.Java 启动SystemUIService
static final void startSystemUi(Context context) {
Intent intent = new Intent();
intent.setComponent(new ComponentName("com.android.systemui",
"com.android.systemui.SystemUIService"));
//Slog.d(TAG, "Starting service: " + intent);
context.startServiceAsUser(intent, UserHandle.OWNER);
}
SystemUIService.java
public void onCreate() {
super.onCreate();
((SystemUIApplication) getApplication()).startServicesIfNeeded();
}
SystemUIApplication.java
mServices[i].start() 启动了各种Service，但是它们并不是真正的Service ，继承了SystemUI.java这个抽象类，复写了start()方法
private final Class<?>[] SERVICES = new Class[] {
com.android.systemui.keyguard.KeyguardViewMediator.class,
com.android.systemui.recent.Recents.class,
com.android.systemui.volume.VolumeUI.class,
com.android.systemui.statusbar.SystemBars.class,
com.android.systemui.usb.StorageNotification.class,
com.android.systemui.power.PowerUI.class,
com.android.systemui.media.RingtonePlayer.class
};
public void startServicesIfNeeded() {
if (mServicesStarted) {
return;
}
if (!mBootCompleted) {
// check to see if maybe it was already completed long before we began
// see ActivityManagerService.finishBooting()
if ("1".equals(SystemProperties.get("sys.boot_completed"))) {
mBootCompleted = true;
if (DEBUG) Log.v(TAG, "BOOT_COMPLETED was already sent");
}
}
Log.v(TAG, "Starting SystemUI services.");
final int N = SERVICES.length;
for (int i=0; i<N; i++) {
Class<?> cl = SERVICES[i];
if (DEBUG) Log.d(TAG, "loading: " + cl);
try {
mServices[i] = (SystemUI)cl.newInstance();
} catch (IllegalAccessException ex) {
throw new RuntimeException(ex);
} catch (InstantiationException ex) {
throw new RuntimeException(ex);
}
mServices[i].mContext = this;
mServices[i].mComponents = mComponents;
if (DEBUG) Log.d(TAG, "running: " + mServices[i]);
//调用所有的service的start方法
mServices[i].start();
//手机启动完成后，完成的事
if (mBootCompleted) {
mServices[i].onBootCompleted();
}
}
mServicesStarted = true;
}
因为我现在要分析status bar ， 所以关注SystemBar.java 的start() 方法
@Override
public void start() {
if (DEBUG) Log.d(TAG, "start");
//ServiceMonitor是个监听器，这里就是监听这个BAR_SERVICE_COMPONENT是否改变
mServiceMonitor = new ServiceMonitor(TAG, DEBUG,
mContext, Settings.Secure.BAR_SERVICE_COMPONENT, this);
//这里看到注释，如果Service不存在 ，就调用onNoService->createStatusBarFromConfig();
mServiceMonitor.start(); // will call onNoService if no remote service is found
}
ServiceMonitor.java
public ServiceMonitor(String ownerTag, boolean debug,
Context context, String settingKey, Callbacks callbacks) {
mTag = ownerTag + ".ServiceMonitor";
mDebug = debug;
mContext = context;
mSettingKey = settingKey;
mCallbacks = callbacks;
}
public void start() {
// listen for setting changes
ContentResolver cr = mContext.getContentResolver();
cr.registerContentObserver(Settings.Secure.getUriFor(mSettingKey),
false /*notifyForDescendents*/, mSettingObserver, UserHandle.USER_ALL);
// listen for package/component changes
IntentFilter filter = new IntentFilter();
filter.addAction(Intent.ACTION_PACKAGE_ADDED);
filter.addAction(Intent.ACTION_PACKAGE_CHANGED);
filter.addDataScheme("package");
mContext.registerReceiver(mBroadcastReceiver, filter);
mHandler.sendEmptyMessage(MSG_START_SERVICE);
}
这个类就是来监听这个
Settings
.
Secure
.
BAR_SERVICE_COMPONENT
的改变，并看情况如何启动Service。再看mHandler的处理
private final Handler mHandler = new Handler() {
public void handleMessage(Message msg) {
switch(msg.what) {
case MSG_START_SERVICE:
startService();
break;
case MSG_CONTINUE_START_SERVICE:
continueStartService();
break;
case MSG_STOP_SERVICE:
stopService();
break;
case MSG_PACKAGE_INTENT:
packageIntent((Intent)msg.obj);
break;
case MSG_CHECK_BOUND:
checkBound();
break;
case MSG_SERVICE_DISCONNECTED:
serviceDisconnected((ComponentName)msg.obj);
break;
}
}
};
private void startService() {
//获取Service的ComponentName
mServiceName = getComponentNameFromSetting();
if (mDebug) Log.d(mTag, "startService mServiceName=" + mServiceName);
if (mServiceName == null) {
mBound = false;
//如果没有Service，就回调，从之前的看，就是start PhoneStatusBar
mCallbacks.onNoService();
} else {
//喜闻乐见的bindService,说破天就是在启动PhoneStatusBar
long delay = mCallbacks.onServiceStartAttempt();
mHandler.sendEmptyMessageDelayed(MSG_CONTINUE_START_SERVICE, delay);
}
}
private ComponentName getComponentNameFromSetting() {
String cn = Settings.Secure.getStringForUser(mContext.getContentResolver(),
mSettingKey, UserHandle.USER_CURRENT);
return cn == null ? null : ComponentName.unflattenFromString(cn);
}
这里就是通过
getComponentNameFromSetting() 获取sevice的Component name,如果不存在就回调onNoservice方法，这个跟前面的注释实际就产生对应
SystemBar.java实现了这个回调接口，可以查到R.string.config_statusBarComponent的值 ，就是PhoneStatusBar
@Overridepublic void onNoService() {if (DEBUG) Log.d(TAG, "onNoService");createStatusBarFromConfig(); // fallback to using an in-process implementation}private void createStatusBarFromConfig() {if (DEBUG) Log.d(TAG, "createStatusBarFromConfig");//<string name="config_statusBarComponent" translatable="false">com.android.systemui.statusbar.phone.PhoneStatusBar</string>final String clsName = mContext.getString(R.string.config_statusBarComponent);if (clsName == null || clsName.length() == 0) {throw andLog("No status bar component configured", null);}Class<?> cls = null;try {cls = mContext.getClassLoader().loadClass(clsName);} catch (Throwable t) {throw andLog("Error loading status bar component: " + clsName, t);}try {mStatusBar = (BaseStatusBar) cls.newInstance();} catch (Throwable t) {throw andLog("Error creating status bar component: " + clsName, t);}mStatusBar.mContext = mContext;mStatusBar.mComponents = mComponents;mStatusBar.start();if (DEBUG) Log.d(TAG, "started " + mStatusBar.getClass().getSimpleName());}
说破天，最终就是为了PhoneStatusBar.java的start() 方法
PhoneStatusBar.java
public void start() {mDisplay = ((WindowManager)mContext.getSystemService(Context.WINDOW_SERVICE)).getDefaultDisplay();updateDisplaySize();mScrimSrcModeEnabled = mContext.getResources().getBoolean(R.bool.config_status_bar_scrim_behind_use_src);/// M: [SystemUI] Support Smartbook Feature. @{if (SIMHelper.isMtkSmartBookSupport()) {/// M: [ALPS01097705] Query the plug-in state as soon as possible.mIsDisplayDevice = SIMHelper.isSmartBookPluggedIn(mContext);Log.v(TAG, "start, mIsDisplayDevice=" + mIsDisplayDevice);}/// @}
super.start(); // calls createAndAddWindows()mMediaSessionManager= (MediaSessionManager) mContext.getSystemService(Context.MEDIA_SESSION_SERVICE);// TODO: use MediaSessionManager.SessionListener to hook us up to future updates// in session state//添加Navigation BaraddNavigationBar();// Lastly, call to the icon policy to install/update all the icons.mIconPolicy = new PhoneStatusBarPolicy(mContext, mCastController, mHotspotController);mSettingsObserver.onChange(false); // set upmHeadsUpObserver.onChange(true); // set upif (ENABLE_HEADS_UP) {mContext.getContentResolver().registerContentObserver(Settings.Global.getUriFor(Settings.Global.HEADS_UP_NOTIFICATIONS_ENABLED), true,mHeadsUpObserver);mContext.getContentResolver().registerContentObserver(Settings.Global.getUriFor(SETTING_HEADS_UP_TICKER), true,mHeadsUpObserver);}mUnlockMethodCache = UnlockMethodCache.getInstance(mContext);mUnlockMethodCache.addListener(this);//启动锁屏startKeyguard();mDozeServiceHost = new DozeServiceHost();putComponent(DozeHost.class, mDozeServiceHost);putComponent(PhoneStatusBar.class, this);setControllerUsers();notifyUserAboutHiddenNotifications();mScreenPinningRequest = new ScreenPinningRequest(mContext);}
现在要看的是StatusBar, 所以看super.start(),也就是 BaseStatusBar.java 的start()
BaseStatusBar.java
public void start() {mWindowManager = (WindowManager)mContext.getSystemService(Context.WINDOW_SERVICE);mWindowManagerService = WindowManagerGlobal.getWindowManagerService();mDisplay = mWindowManager.getDefaultDisplay();mDevicePolicyManager = (DevicePolicyManager)mContext.getSystemService(Context.DEVICE_POLICY_SERVICE);mNotificationColorUtil = NotificationColorUtil.getInstance(mContext);mNotificationData = new NotificationData(this);mAccessibilityManager = (AccessibilityManager)mContext.getSystemService(Context.ACCESSIBILITY_SERVICE);mDreamManager = IDreamManager.Stub.asInterface(ServiceManager.checkService(DreamService.DREAM_SERVICE));mPowerManager = (PowerManager) mContext.getSystemService(Context.POWER_SERVICE);mSettingsObserver.onChange(false); // set upmContext.getContentResolver().registerContentObserver(Settings.Global.getUriFor(Settings.Global.DEVICE_PROVISIONED), true,mSettingsObserver);mContext.getContentResolver().registerContentObserver(Settings.Global.getUriFor(Settings.Global.ZEN_MODE), false,mSettingsObserver);mContext.getContentResolver().registerContentObserver(Settings.Secure.getUriFor(Settings.Secure.LOCK_SCREEN_SHOW_NOTIFICATIONS), false,mSettingsObserver,UserHandle.USER_ALL);mContext.getContentResolver().registerContentObserver(Settings.Secure.getUriFor(Settings.Secure.LOCK_SCREEN_ALLOW_PRIVATE_NOTIFICATIONS),true,mLockscreenSettingsObserver,UserHandle.USER_ALL);//加载statusbarservicemBarService = IStatusBarService.Stub.asInterface(ServiceManager.getService(Context.STATUS_BAR_SERVICE));//mRecents = getComponent(RecentsComponent.class);mRecents.setCallback(this);final Configuration currentConfig = mContext.getResources().getConfiguration();mLocale = currentConfig.locale;mLayoutDirection = TextUtils.getLayoutDirectionFromLocale(mLocale);mFontScale = currentConfig.fontScale;mUserManager = (UserManager) mContext.getSystemService(Context.USER_SERVICE);mLinearOutSlowIn = AnimationUtils.loadInterpolator(mContext,android.R.interpolator.linear_out_slow_in);mFastOutLinearIn = AnimationUtils.loadInterpolator(mContext,android.R.interpolator.fast_out_linear_in);// Connect in to the status bar manager serviceStatusBarIconList iconList = new StatusBarIconList();mCommandQueue = new CommandQueue(this, iconList);int[] switches = new int[8];ArrayList<IBinder> binders = new ArrayList<IBinder>();try {mBarService.registerStatusBar(mCommandQueue, iconList, switches, binders);} catch (RemoteException ex) {// If the system process isn't there we're doomed anyway.}//就是为了调用这里，加载status barcreateAndAddWindows();disable(switches[0], false /* animate */);setSystemUiVisibility(switches[1], 0xffffffff);topAppWindowChanged(switches[2] != 0);// StatusBarManagerService has a back up of IME token and it's restored here.setImeWindowStatus(binders.get(0), switches[3], switches[4], switches[5] != 0);// Set up the initial icon stateint N = iconList.size();int viewIndex = 0;for (int i=0; i<N; i++) {StatusBarIcon icon = iconList.getIcon(i);if (icon != null) {addIcon(iconList.getSlot(i), i, viewIndex, icon);viewIndex++;}}// Set up the initial notification state.try {mNotificationListener.registerAsSystemService(mContext,new ComponentName(mContext.getPackageName(), getClass().getCanonicalName()),UserHandle.USER_ALL);} catch (RemoteException e) {Log.e(TAG, "Unable to register notification listener", e);}if (DEBUG) {Log.d(TAG, String.format("init: icons=%d disabled=0x%08x lights=0x%08x menu=0x%08x imeButton=0x%08x",iconList.size(),switches[0],switches[1],switches[2],switches[3]));}mCurrentUserId = ActivityManager.getCurrentUser();setHeadsUpUser(mCurrentUserId);IntentFilter filter = new IntentFilter();filter.addAction(Intent.ACTION_USER_SWITCHED);filter.addAction(Intent.ACTION_USER_ADDED);filter.addAction(BANNER_ACTION_CANCEL);filter.addAction(BANNER_ACTION_SETUP);filter.addAction(DevicePolicyManager.ACTION_DEVICE_POLICY_MANAGER_STATE_CHANGED);mContext.registerReceiver(mBroadcastReceiver, filter);updateCurrentProfilesCache();}
这里搞了一大堆，其实是就为了createAndAddWindows();

system_icon_area里面有个clock，当然就是最右边的时间了

但是，但是，我们看手机的时候，居然没有电量百分比显示出来 ，这让很多客户就有点恼火，后面再说

看看手机，就知道这是什么图标了，但是但是，这里他妈的居然出现了
@+id/battery_level
，但是这个battery_level可不是你想显示就显示的，它要在充电状态下才显示电量到底有多少，fuck~, 真是他妈的看不懂这个设计,难道就是为了简化不必要的设计
