show_native_keyboard()

int show_native_keyboard

(

struct graphics_keyboard *

kbd

)

Displays the native input method.

This method decides whether a native on-screen input method, such as a virtual keyboard, needs to be displayed. A typical case in which there is no need for an on-screen input method is if a hardware keyboard is present.

Note that the Android platform lacks reliable means of determining whether an on-screen input method is going to be displayed or how much screen space it is going to occupy. Therefore this method tries to guess these values. They have been tested and found to work correctly with the AOSP keyboard, and are thus expected to be compatible with most on-screen keyboards found on the market, but results may be unexpected with other input methods.

Parameters

kbd	A struct graphics_keyboard which describes the requirements for the input method and will be populated with the data of the input method before the function returns.

Returns

True if the input method is going to be displayed, false if not.
