Android13-SystemUI_下拉栏-快捷设置区域自定义高度调整

quick_status_bar_expanded_header.xml(QuickStatusBarHeader根控件)的背景颜色

第一次下滑

绿色是QuickQSPanel控件的背景颜色

蓝色是quick_status_bar_expanded_header.xml(QuickStatusBarHeader根控件)的背景颜色

橙色是qs_panel.xml(QSContainerImpl根控件)占用背景效果

第二次下滑

绿色消失不见

蓝色是quick_status_bar_expanded_header.xml(QuickStatusBarHeader根控件)的背景颜色

紫色是QSPanel控件的背景颜色

橙色是qs_panel.xml(QSContainerImpl根控件)的背景颜色

QuickStatusBarHeader控件自定义自己高度的效果

QuickStatusBarHeader可以看到在updateResources()方法有配置自己的高度

onFinishInflate()调用到updateResources()方法

        mClockView = findViewById(R.id.clock);
        mDatePrivacySeparator = findViewById(R.id.space);
        // Tint for the battery icons are handled in setupHost()
        mBatteryRemainingIcon = findViewById(R.id.batteryRemainingIcon);

        updateResources();
        Configuration config = mContext.getResources().getConfiguration();
        setDatePrivacyContainersWidth(config.orientation == Configuration.ORIENTATION_LANDSCAPE);

        // QS will always show the estimate, and BatteryMeterView handles the case where
        // it's unavailable or charging
        mBatteryRemainingIcon.setPercentShowMode(BatteryMeterView.MODE_ESTIMATE);

        mIconsAlphaAnimatorFixed = new TouchAnimator.Builder()
                .addFloat(mIconContainer, "alpha", 0, 1)
                .addFloat(mBatteryRemainingIcon, "alpha", 0, 1)
                .build();
    }

简单的布局文件层级分析

status_bar_expanded.xml(NotificationPanelView根控件)

NotificationsQuickSettingsContainer
- qs_panel.xml(QSContainerImpl根控件)
  - NonInterceptingScrollView
    - QSPanel，第二次下滑时快捷设置区域
  - quick_status_bar_expanded_header.xml(QuickStatusBarHeader根控件)
    - RelativeLayout
      - QuickQSPanel，第一次下滑快捷设置区域，第二次下滑会被隐藏掉
