在系统SystemUI中它主要负责反馈系统及应用状态并与用户保持大量的交互,systemui中主要核心布局控件为以下部分 在SystemUI中QSPanel 创建是从 StatusBar#makeStatusBarView 开始的 接下来分析的核心功能和布局如下: StatusBar通知消息提示和状态展现 NavigationBar返回HOMERecent KeyGuard锁屏模块可以看做单独的应用提供基本的手机个人隐私保护 Recents近期应用管理以堆叠栈的形式展现。 Notification Panel展示系统或应用通知内容。提供快速系统设置开关。 VolumeUI来用展示或控制音量的变化媒体音量、铃声音量与闹钟音量 截屏界面长按电源键音量下键后截屏用以展示截取的屏幕照片/内容 PowerUI主要处理和Power相关的事件比如省电模式切换、电池电量变化和开关屏事件等。 RingtonePlayer铃声播放 StackDivider控制管理分屏 PipUI提供对于画中画模式的管理 3.1 status_bar_expanded.xml下拉状态栏布局分析

/com.android.systemui.statusbar.phone.NotificationPanelView在实现SystemUI下拉状态栏禁止QuickQSPanel展开的核心功能中通过上述的分析得知 从SystemUI中状态栏下拉的布局status_bar_expanded.xml的布局文件可以看到主要的下拉事件 是在NotificationPanelViewController.java中负责的所以具体的下滑事件是在NotificationPanelViewController.java中处理的 所以接下来分析NotificationPanelViewController.java有关下拉状态栏的下滑展开事件 3.2 NotificationPanelViewController.java的下拉状态栏下滑事件分析
NotificationPanelViewController是一个以面板形式展示通知内容的主要视图控制器。它可以显示系统通知 例如来自操作系统的警告、提醒或更新通知以及来自其他应用程序的通知如社交媒体应用或 即时消息应用发送的消息通知。通过notificationPanelViewController用户可以方便地查看和管理收到的通知。 public class NotificationPanelViewController extends PanelViewController { {Overrideprotected TouchHandler createTouchHandler() {return new TouchHandler() {Overridepublic boolean onInterceptTouchEvent(MotionEvent event) {if (mBlockTouches || mQsFullyExpanded mQs.disallowPanelTouches()) {return false;}initDownStates(event);// Do not let touches go to shade or QS if the bouncer is visible,// but still let user swipe down to expand the panel, dismissing the bouncer.if (mStatusBar.isBouncerShowing()) {return true;}if (mBar.panelEnabled() mHeadsUpTouchHelper.onInterceptTouchEvent(event)) {mMetricsLogger.count(COUNTER_PANEL_OPEN, 1);mMetricsLogger.count(COUNTER_PANEL_OPEN_PEEK, 1);return true;}if (!shouldQuickSettingsIntercept(mDownX, mDownY, 0) mPulseExpansionHandler.onInterceptTouchEvent(event)) {return true;}if (!isFullyCollapsed() onQsIntercept(event)) {return true;}return super.onInterceptTouchEvent(event);}
在实现SystemUI下拉状态栏禁止QuickQSPanel展开的核心功能中通过上述的分析得知 在NotificationPanelViewController中的onInterceptTouchEvent(MotionEvent event) 手势下滑上滑事件的 处理而具体处理下拉状态栏下滑事件的是在onQsIntercept(MotionEvent event)中继续处理的 接下来看下onQsIntercept(MotionEvent event)处理手势事件 private boolean onQsIntercept(MotionEvent event) {int pointerIndex event.findPointerIndex(mTrackingPointer);if (pointerIndex 0) {pointerIndex 0;mTrackingPointer event.getPointerId(pointerIndex);}final float x event.getX(pointerIndex);final float y event.getY(pointerIndex);switch (event.getActionMasked()) {case MotionEvent.ACTION_DOWN:mIntercepting true;mInitialTouchY y;mInitialTouchX x;initVelocityTracker();trackMovement(event);if (shouldQuickSettingsIntercept(mInitialTouchX, mInitialTouchY, 0)) {getParent().requestDisallowInterceptTouchEvent(true);}if (mQsExpansionAnimator ! null) {onQsExpansionStarted();mInitialHeightOnTouch mQsExpansionHeight;mQsTracking true;mIntercepting false;mNotificationStackScroller.cancelLongPress();}break;case MotionEvent.ACTION_POINTER_UP:final int upPointer event.getPointerId(event.getActionIndex());if (mTrackingPointer upPointer) {// gesture is ongoing, find a new pointer to trackfinal int newIndex event.getPointerId(0) ! upPointer ? 0 : 1;mTrackingPointer event.getPointerId(newIndex);mInitialTouchX event.getX(newIndex);mInitialTouchY event.getY(newIndex);}break;case MotionEvent.ACTION_MOVE:final float h y - mInitialTouchY;trackMovement(event);if (mQsTracking) {// Already tracking because onOverscrolled was called. We need to update here// so we dont stop for a frame until the next touch event gets handled in// onTouchEvent.setQsExpansion(h mInitialHeightOnTouch);trackMovement(event);mIntercepting false;return true;}if (Math.abs(h) mTouchSlop Math.abs(h) Math.abs(x - mInitialTouchX) shouldQuickSettingsIntercept(mInitialTouchX, mInitialTouchY, h)) {mQsTracking true;onQsExpansionStarted();notifyExpandingFinished();mInitialHeightOnTouch mQsExpansionHeight;mInitialTouchY y;mInitialTouchX x;mIntercepting false;mNotificationStackScroller.cancelLongPress();return true;}break;case MotionEvent.ACTION_CANCEL:case MotionEvent.ACTION_UP:trackMovement(event);if (mQsTracking) {flingQsWithCurrentVelocity(y,event.getActionMasked() MotionEvent.ACTION_CANCEL);mQsTracking false;}mIntercepting false;break;}return false;}
在实现SystemUI下拉状态栏禁止QuickQSPanel展开的核心功能中通过上述的分析得知 在NotificationPanelViewController中onQsIntercept(MotionEvent event)的是具体处理下拉事件的方法 在case MotionEvent.ACTION_MOVE:中可以根据手势滑动的距离来设置下拉状态栏中的 QSPanel展开和收缩通过setQsExpansion(h mInitialHeightOnTouch);来根据手势滑动的 距离来设置QSPanel是否需要展开所以具体看下setQsExpansion的相关代码 private void setQsExpansion(float height) {// add core startif (mQs ! null) return;//add core endheight Math.min(Math.max(height, mQsMinExpansionHeight), mQsMaxExpansionHeight);mQsFullyExpanded height mQsMaxExpansionHeight mQsMaxExpansionHeight ! 0;if (height mQsMinExpansionHeight !mQsExpanded !mStackScrollerOverscrolling) {setQsExpanded(true);} else if (height mQsMinExpansionHeight mQsExpanded) {setQsExpanded(false);}mQsExpansionHeight height;updateQsExpansion();requestScrollerTopPaddingUpdate(false /* animate */);updateHeaderKeyguardAlpha();if (mBarState StatusBarState.SHADE_LOCKED|| mBarState StatusBarState.KEYGUARD) {updateKeyguardBottomAreaAlpha();updateBigClockAlpha();}if (mBarState StatusBarState.SHADE mQsExpanded !mStackScrollerOverscrolling mQsScrimEnabled) {mQsNavbarScrim.setAlpha(getQsExpansionFraction());}if (mAccessibilityManager.isEnabled()) {setAccessibilityPaneTitle(determineAccessibilityPaneTitle());}if (!mFalsingManager.isUnlockingDisabled() mQsFullyExpanded mFalsingManager.shouldEnforceBouncer()) {mStatusBar.executeRunnableDismissingKeyguard(null, null /* cancelAction */,false /* dismissShade */, true /* afterKeyguardGone */, false /* deferred */);}if (mExpansionListener ! null) {mExpansionListener.onQsExpansionChanged(mQsMaxExpansionHeight ! 0? mQsExpansionHeight / mQsMaxExpansionHeight : 0);}if (DEBUG) {invalidate();}} 4、修改
在实现SystemUI下拉状态栏禁止QuickQSPanel展开的核心功能中通过上述的分析得知 在NotificationPanelViewController.java类中setQsExpansion(float height) 方法来设置下拉状态栏 QSPanel高度的方法中根据高度判断是否需要展开收缩QSPanel,所以通过增加判断
if (mQs ! null)return;
来去掉下滑展开QSPanel就可以做到只显示QuickQSPanel而 不用展开QSPanel实现单次下拉状态栏定制UI 就可以在QuickQSPanel中定制就可以了 private void setQsExpansion(float height) {// mQs 不等于空直接复用if (mQs ! null) return;// mQs 等于空新建height Math.min(Math.max(height, mQsMinExpansionHeight), mQsMaxExpansionHeight);mQsFullyExpanded height mQsMaxExpansionHeight mQsMaxExpansionHeight ! 0;if (height mQsMinExpansionHeight !mQsExpanded !mStackScrollerOverscrolling !mDozing) {setQsExpanded(true);} else if (height mQsMinExpansionHeight mQsExpanded) {setQsExpanded(false);}mQsExpansionHeight height;updateQsExpansion();requestScrollerTopPaddingUpdate(false /* animate */);updateHeaderKeyguardAlpha();if (mBarState StatusBarState.SHADE_LOCKED || mBarState KEYGUARD) {updateKeyguardBottomAreaAlpha();positionClockAndNotifications();updateBigClockAlpha();}if (mAccessibilityManager.isEnabled()) {mView.setAccessibilityPaneTitle(determineAccessibilityPaneTitle());}if (!mFalsingManager.isUnlockingDisabled() mQsFullyExpanded mFalsingCollector.shouldEnforceBouncer()) {mStatusBar.executeRunnableDismissingKeyguard(null, null /* cancelAction */,false /* dismissShade */, true /* afterKeyguardGone */, false /* deferred */);}for (int i 0; i mExpansionListeners.size(); i) {mExpansionListeners.get(i).onQsExpansionChanged(mQsMaxExpansionHeight ! 0 ? mQsExpansionHeight / mQsMaxExpansionHeight : 0);}if (DEBUG) {mView.invalidate();}}
