Android 6.0 Marshmallow 通知栏中QuickSetting分析
在SystemUI中，状态栏和通知栏都是在PhoneStatusBar的makeStatusBarView方法添加进来的,这里主要说说状态栏中的QuickSettingPanel
// ================================================================================
// Constructing the view
// ================================================================================
protected PhoneStatusBarView makeStatusBarView() {
final Context context = mContext;
Resources res = context.getResources();
updateDisplaySize(); // populates mDisplayMetrics
updateResources();
mStatusBarWindow = (StatusBarWindowView) View.inflate(context,
R.layout.super_status_bar, null);
....
mStatusBarView = (PhoneStatusBarView) mStatusBarWindow.findViewById(R.id.status_bar);
mStatusBarView.setBar(this);
PanelHolder holder = (PanelHolder) mStatusBarWindow.findViewById(R.id.panel_holder);
mStatusBarView.setPanelHolder(holder);
mNotificationPanel = (NotificationPanelView) mStatusBarWindow.findViewById(
R.id.notification_panel);
mNotificationPanel.setStatusBar(this);
// Set up the quick settings tile panel
mQSPanel = (QSPanel) mStatusBarWindow.findViewById(R.id.quick_settings_panel);
if (mQSPanel != null) {
final QSTileHost qsh = new QSTileHost(mContext, this,
mBluetoothController, mLocationController, mRotationLockController,
mNetworkController, mZenModeController, mHotspotController,
mCastController, mFlashlightController,
mUserSwitcherController, mKeyguardMonitor,
mSecurityController);
mQSPanel.setHost(qsh);
mQSPanel.setTiles(qsh.getTiles());
mBrightnessMirrorController = new BrightnessMirrorController(mStatusBarWindow);
mQSPanel.setBrightnessMirror(mBrightnessMirrorController);
mHeader.setQSPanel(mQSPanel);
qsh.setCallback(new QSTileHost.Callback() {
@Override
public void onTilesChanged() {
mQSPanel.setTiles(qsh.getTiles());
}
});
}
....
return mStatusBarView;
}
具体图标对应的id在这就不一一说明了，可以自己对着上面的图去看，下面主要分析下这个界面是怎么显示出来的,在PhoneStatusBar的makeStatusBarView方法中加载了super_status_bar.xml文件
mStatusBarWindow = (StatusBarWindowView) View.inflate(context,
R.layout.super_status_bar, null);
....
....
....
在这个布局中包含了status_bar_expanded_header.xml，下面具体看看status_bar_expanded_header这个布局文件，这个布局文件中主要包含了亮度调节框上面那一部分
public QSPanel(Context context, AttributeSet attrs) {
super(context, attrs);
mContext = context;
mDetail = LayoutInflater.from(context).inflate(R.layout.qs_detail, this, false);
mDetailContent = (ViewGroup) mDetail.findViewById(android.R.id.content);
mDetailSettingsButton = (TextView) mDetail.findViewById(android.R.id.button2);
mDetailDoneButton = (TextView) mDetail.findViewById(android.R.id.button1);
updateDetailText();
mDetail.setVisibility(GONE);
mDetail.setClickable(true);
mBrightnessView = LayoutInflater.from(context).inflate(
R.layout.quick_settings_brightness_dialog, this, false);
mFooter = new QSFooter(this, context);
addView(mDetail);
addView(mBrightnessView);
addView(mFooter.getView());
mClipper = new QSDetailClipper(mDetail);
updateResources();
mBrightnessController = new BrightnessController(getContext(),
(ImageView) findViewById(R.id.brightness_icon),
(ToggleSlider) findViewById(R.id.brightness_slider)); // Set up the quick settings tile panel
mQSPanel = (QSPanel) mStatusBarWindow.findViewById(R.id.quick_settings_panel);
if (mQSPanel != null) {
final QSTileHost qsh = new QSTileHost(mContext, this,

mQSPanel.setTiles(qsh.getTiles());
mBrightnessMirrorController = new BrightnessMirrorController(mStatusBarWindow);
mQSPanel.setBrightnessMirror(mBrightnessMirrorController);
mHeader.setQSPanel(mQSPanel);
qsh.setCallback(new QSTileHost.Callback() {
@Override

});

}看是不是有对应event事件被拦截了，导致控件本身的event事件没有响应到。
