Abstract
A first electronic device establishes a projection connection to a second electronic device by determining a security layer in a to-be-combined layer of a to-be-projected interface, where a flag bit of the security layer is a first value, changing the first value to a second value, combining the to-be-combined layer based on the second value, to display a composed layer on a display area corresponding to a security layer, and sending projection data to the second electronic device, where the projection data includes the composed layer.
Claims20
A method implemented by a first electronic device and comprising:
- changing a first value of a flag bit of a security layer in a to-be-combined layer of a to-be-projected interface to a second value;
- combining, based on the second value, the to-be-combined layer with the security layer to display a composed layer in a display area corresponding to the security layer;
- and
- sending projection data to a second electronic device, wherein the projection data comprises the composed layer.
A first electronic device comprising:
- a memory configured to store a computer program;
- and
- one or more processors coupled to the memory and configured to execute the computer program to cause the first electronic device to:
- change a first value of a flag bit of a security layer in a to-be-combined layer of a to-be-projected interface to a second value;
- combine, based on the second value, the to-be-combined layer with the security layer to display a composed layer in a display area corresponding to the security layer;
- and
- send projection data to a second electronic device, wherein the projection data comprises the composed layer.
