how to change the portrait touch mode

[hyun-moyang]

Hi All,

I have changed the screen mode from the landscape to the portrait in Android Q10.0.0_2.4.0_AUTO in iMX8QM Mek Board.

But I have a problem with the input of touch to use the USB interface. The input of touch is the abnormal operation in the portrait screen mode. When inputting a touch, the touch input works only when inputting in the landscape screen mode. For example, the touch events input in the landscape screen mode ONLY operates.

So, I want how to be able to enter the input of touch to the portrait screen.

Please help me to solve the issue.

Regards

HM

Hi,

   try the way, please!

----------------------------------------

frameworks/native/services/inputflinger/InputReader.cpp

void TouchInputMapper::configureSurface(nsecs_t when, bool* outResetNeeded) {
int32_t oldDeviceMode = mDeviceMode;

......

if (viewportChanged) {
       mViewport = newViewport;

/* add code like below, or you can also add rotation property in init.rc, then get the propery here, and using "if" to judge it */

mViewport.orientation = DISPLAY_ORIENTATION_0; // if rotate 0 degree.

mViewport.orientation = DISPLAY_ORIENTATION_90;// if rotate 90 degree.

mViewport.orientation = DISPLAY_ORIENTATION_180;// if rotate 180 degree

mViewport.orientation = DISPLAY_ORIENTATION_270;// if rotate 270 degree

  if (mDeviceMode == DEVICE_MODE_DIRECT || mDeviceMode == DEVICE_MODE_POINTER) {

......

Have a nice day!

B.R,
