@ohos.inputMethod (Input Method Framework)

The inputMethod module is oriented to common foreground applications (third-party applications and system applications such as Notes, Messaging, and Settings). It provides input method control and management capabilities, including displaying or hiding the soft keyboard, switching between input methods, and obtaining the list of all input methods.

NOTE

The initial APIs of this module are supported since API version 6. Newly added APIs will be marked with a superscript to indicate their earliest API version.
