Android主副屏显示-Android13

  • 1、DisplayDeviceInfo屏幕信息
  • 2、每个屏幕对应LogicalDisplay
    • 2.1 LogicalDisplay添加对应DisplayContent
    • 2.2 configureDisplayLocked刷新

DisplayManagerService启动及主屏添加-Android13

1、DisplayDeviceInfo屏幕信息

DisplayManagerService启动及主屏添加-Android13 中监听获取，在LocalDisplayAdapter.java#tryConnectDisplayLocked 获取 DisplayDevice 信息，在DisplayDeviceRepository.java#handleDisplayDeviceAdded 获取 DisplayDeviceInfo （ 即 DisplayDevice.getDisplayDeviceInfoLocked()）

命令查看屏幕信息：

$ dumpsys SurfaceFlinger --display-id

2、每个屏幕对应LogicalDisplay

frameworks/base/services/core/java/com/android/server/wm/RootWindowContainer.java
frameworks/base/services/core/java/com/android/server/wm/DisplayContent.java
frameworks/base/services/core/java/com/android/server/display/LogicalDisplay.java

RootWindowContainer.java#onDisplayAdded

DisplayContent.java#updateDisplayAndOrientation

DisplayManagerService.java#setDisplayInfoOverrideFromWindowManager

LogicalDisplay.java#setDisplayInfoOverrideFromWindowManagerLocked

2.1 LogicalDisplay添加对应DisplayContent

在这里插入图片描述

2.2 configureDisplayLocked刷新

RootWindowContainer.java#applySurfaceChangesTransaction

DisplayManagerService.java#performTraversalLocked

DisplayManagerService.java#configureDisplayLocked

LogicalDisplay.java#configureDisplayLocked

主屏：1080x2160

mDisplayId=0; orientation=0; physWidth=1080; physHeight=2160; rotated=false [ displayDeviceInfo.rotation=0; displayDeviceInfo.width=1080; displayDeviceInfo.height=2160; displayInfo.rotation=0; displayInfo.logicalWidth=1080; displayInfo.logicalHeight=2160 ]
mDisplayId=0; mTempDisplayRect=Rect(0, 0 - 1080, 2160); mTempLayerStackRect=Rect(0, 0 - 1080, 2160); orientation=0mDisplayId=0; orientation=1; physWidth=2160; physHeight=1080; rotated=true [ displayDeviceInfo.rotation=0; displayDeviceInfo.width=1080; displayDeviceInfo.height=2160; displayInfo.rotation=1; displayInfo.logicalWidth=2160; displayInfo.logicalHeight=1080 ]
mDisplayId=0; mTempDisplayRect=Rect(0, 0 - 2160, 1080); mTempLayerStackRect=Rect(0, 0 - 2160, 1080); orientation=1

副屏：1920x1080 （修改处理？）

mDisplayId=2; orientation=0; physWidth=1920; physHeight=1080 [ displayDeviceInfo.rotation=0; displayDeviceInfo.width=1920; displayDeviceInfo.height=1080; displayInfo.rotation=0; displayInfo.logicalWidth=1920; displayInfo.logicalHeight=1080 ]
