Android frameworks 开发总结之八

Quick Settings增加一項

XXX device要求在quick settings中增加一項touch panel.

• 在/frameworks/base/packages/SystemUI/res/values/config.xml文件中的quick_settings_tiles_default string 中增加touch panel。並在String resource文件中增加顯示的title

<!-- The default tiles to display in QuickSettings --><string name="quick_settings_tiles_default" translatable="false">wifi,bt,dnd,touchpanel,flashlight,rotation,battery,cell,airplane,cast</string>

• 在frameworks/base/packages/SystemUI/src/com/android/systemui/qs/tiles　下增加TouchPanelTile.java文件.

}

• 在frameworks/base/proto/src/metrics_constants/metrics_constants.proto 文件中增加 MetricsEvent.QS_TOUCHPANEL

// OPEN: QS Touch Panel tile shown// ACTION: QS Touch Panel tile tapped//  SUBTYPE: 0 is off, 1 is finger, 2 is glove, 3 is stylus// CATEGORY: QUICK_SETTINGSQS_TOUCHPANEL = 1751;

• 在frameworks/base/packages/SystemUI/src/com/android/systemui/qs/tileimpl/QSFactoryImpl.java 文件中實現
