扬州哪里做网站域名反查

要求：主屏在左，副屏在右。这种排列情况下鼠标仅可通过主屏的最右侧移入副屏的最左侧，或从副屏的最左侧移入主屏最右侧。

1.RK默认设计

1.1 RK的代码设计是当sys.mouse.presentation=1时，鼠标在屏幕边缘的时候就会移入另一个屏幕

• frameworks/native/services/inputflinger/reader/mapper/CursorInputMapper.cpp

void CursorInputMapper::sync(nsecs_t when) {...if (mSource == AINPUT_SOURCE_MOUSE) {if (moved || scrolled || buttonsChanged) {mPointerController->setPresentation(PointerControllerInterface::PRESENTATION_POINTER);if (moved) {mPointerController->move(deltaX, deltaY);}if (buttonsChanged) {mPointerController->setButtonState(currentButtonState);}mPointerController->unfade(PointerControllerInterface::TRANSITION_IMMEDIATE);}mPointerController->getPosition(&xCursorPosition, &yCursorPosition);pointerCoords.setAxisValue(AMOTION_EVENT_AXIS_X, xCursorPosition);pointerCoords.setAxisValue(AMOTION_EVENT_AXIS_Y, yCursorPosition);pointerCoords.setAxisValue(AMOTION_EVENT_AXIS_RELATIVE_X, deltaX);pointerCoords.setAxisValue(AMOTION_EVENT_AXIS_RELATIVE_Y, deltaY);char mMousePresentation[PROPERTY_VALUE_MAX] = {0};property_get("sys.mouse.presentation", mMousePresentation, "0");if (strcmp(mMousePresentation, "1") == 0) {displayId = mDisplayId;float minX, minY, maxX, maxY;if (mPointerController->getBounds(&minX, &minY, &maxX, &maxY)) {// 如果鼠标位置在屏幕四周边缘，进入另外的屏幕，重新赋值displayIdif (xCursorPosition==minX||xCursorPosition==maxX||yCursorPosition==minY||yCursorPosition==maxY{displayId=getPolicy()->notifyDisplayIdChanged();mDisplayId=displayId;}}}else{displayId = mPointerController->getDisplayId();}} else {pointerCoords.setAxisValue(AMOTION_EVENT_AXIS_X, deltaX);pointerCoords.setAxisValue(AMOTION_EVENT_AXIS_Y, deltaY);displayId = ADISPLAY_ID_NONE;}
}

1.2 鼠标进入不同屏，默认居中显示

• frameworks/base/libs/input/PointerController.cpp

void PointerController::setDisplayViewport(const DisplayViewport& viewport) {...// Reset cursor position to center if size or display changed.if (oldViewport.displayId != viewport.displayId|| oldDisplayWidth != newDisplayWidth|| oldDisplayHeight != newDisplayHeight) {float minX, minY, maxX, maxY;if (getBoundsLocked(&minX, &minY, &maxX, &maxY)) {mLocked.pointerX = (minX + maxX) * 0.5f;mLocked.pointerY = (minY + maxY) * 0.5f;// Reload icon resources for density may be changed.loadResourcesLocked();} else {mLocked.pointerX = 0;mLocked.pointerY = 0;}fadeOutAndReleaseAllSpotsLocked();} else if (oldViewport.orientation != viewport.orientation) {
}

2.修改鼠标进入方式

hdmi接入状态

• /frameworks/base/services/core/java/com/android/server/WiredAccessoryManager.java

public Pair<Integer, Integer> parseState(ExtconInfo extconInfo, String status) {...if (status.contains("HDMI")){SystemProperties.set("hdmi.plugged", status.contains("HDMI=1") ? "1":"0");}
}

2.1 主屏在左，副屏在右边模式下修改鼠标进入方式

• frameworks/native/services/inputflinger/reader/mapper/CursorInputMapper.cpp

void CursorInputMapper::sync(nsecs_t when) {...if (mSource == AINPUT_SOURCE_MOUSE) {if (moved || scrolled || buttonsChanged) {mPointerController->setPresentation(PointerControllerInterface::PRESENTATION_POINTER);if (moved) {mPointerController->move(deltaX, deltaY);}if (buttonsChanged) {mPointerController->setButtonState(currentButtonState);}mPointerController->unfade(PointerControllerInterface::TRANSITION_IMMEDIATE);}mPointerController->getPosition(&xCursorPosition, &yCursorPosition);pointerCoords.setAxisValue(AMOTION_EVENT_AXIS_X, xCursorPosition);pointerCoords.setAxisValue(AMOTION_EVENT_AXIS_Y, yCursorPosition);pointerCoords.setAxisValue(AMOTION_EVENT_AXIS_RELATIVE_X, deltaX);pointerCoords.setAxisValue(AMOTION_EVENT_AXIS_RELATIVE_Y, deltaY);char mMousePresentation[PROPERTY_VALUE_MAX] = {0};property_get("sys.mouse.presentation", mMousePresentation, "0");if (strcmp(mMousePresentation, "1") == 0) {//displayId = mDisplayId;char mHdmiPlugged[PROPERTY_VALUE_MAX] = {0};property_get("hdmi.plugged", mHdmiPlugged, "0");if (strcmp(mHdmiPlugged, "1") == 0){displayId = mDisplayId;} else {// 鼠标在副屏时，拔掉hdmi导致鼠标没有功能，强制id为主屏0displayId = 0;}  float minX, minY, maxX, maxY;if (mPointerController->getBounds(&minX, &minY, &maxX, &maxY)){// 鼠标在主屏屏幕右边缘位置，重新赋值displayId，位置改变if (displayId == 0 && xCursorPosition==maxX) {displayId=getPolicy()->notifyDisplayIdChanged();mDisplayId=displayId;// 设置鼠标在副屏左侧显示if ((strcmp(mHdmiPlugged, "1") == 0)){mPointerController->setPosition(minX+10, yCursorPosition);}}// 鼠标在副屏屏幕左边缘位置，重新赋值displayId，位置改变（（主屏id默认为0，副屏id切换后递增））if (displayId != 0 && xCursorPosition==minX){displayId=getPolicy()->notifyDisplayIdChanged();mDisplayId=displayId;// 设置鼠标在主屏右侧显示mPointerController->setPosition(maxX-10, yCursorPosition);}} }else{displayId = mPointerController->getDisplayId();}} else {pointerCoords.setAxisValue(AMOTION_EVENT_AXIS_X, deltaX);pointerCoords.setAxisValue(AMOTION_EVENT_AXIS_Y, deltaY);displayId = ADISPLAY_ID_NONE;}
}
