The invention discloses a display method of handwritten content and an electronic device. The method comprises the following steps: when a handwritten trigger instruction for inputting handwritten content is detected, a user-defined layer corresponding to the handwritten content is applied through a Java virtual machine; The corresponding handwriting process is started by the preset handwriting program in the system, and the layer identification of the user-defined layer is transferred to the handwriting process. The handwriting process draws the user-input handwriting content in the custom layer according to the layer identification of the custom layer, and modifies the image data stored in the display cache according to the handwriting content input by the user, so that the display cachesynchronizes the modified image data to the display screen. The method avoids the lagging phenomenon caused by the garbage collection operation in the prior art, improves the fluency of the handwriting input operation, and improves the user experience.
