Functions

func SetLifecycleCallbacks

func SetLifecycleCallbacks(cb LifecycleCallbacks)

SetLifecycleCallbacks registers callbacks for the lifecycle events.

Types

type Activity

type Activity struct {
	// contains filtered or unexported fields
}

Activity wraps the NDK ANativeActivity handle.

func NewActivityFromPointer

func NewActivityFromPointer(ptr unsafe.Pointer) *Activity

NewActivityFromPointer wraps a raw ANativeActivity pointer.

func NewActivityFromUintPtr

func NewActivityFromUintPtr(ptr uintptr) *Activity

NewActivityFromUintPtr wraps a uintptr as a Activity. The caller must ensure ptr points to a valid ANativeActivity.

func (*Activity) Finish

func (h *Activity) Finish()

Finish calls the underlying NDK function.

func (*Activity) HideSoftInput

func (h *Activity) HideSoftInput(flags uint32)

HideSoftInput calls the underlying NDK function.

func (*Activity) Pointer

func (h *Activity) Pointer() unsafe.Pointer

Pointer returns the underlying pointer as unsafe.Pointer.

func (*Activity) SetWindowFlags

func (h *Activity) SetWindowFlags(addFlags uint32, removeFlags uint32)

SetWindowFlags calls the underlying NDK function.

func (*Activity) SetWindowFormat

func (h *Activity) SetWindowFormat(format int32)

SetWindowFormat calls the underlying NDK function.

func (*Activity) ShowSoftInput

func (h *Activity) ShowSoftInput(flags uint32)

ShowSoftInput calls the underlying NDK function.

func (*Activity) UintPtr

func (h *Activity) UintPtr() uintptr

UintPtr returns the underlying pointer as a uintptr. This is useful for interop with gomobile bind, golang.org/x/mobile, gioui.org, and other packages that represent native handles as uintptr.

type Error

type Error int32

Error represents an NDK error code.

func (Error) Error

func (e Error) Error() string

type HideSoftInputFlags

type HideSoftInputFlags int32

const (
	ImplicitOnly HideSoftInputFlags = 1
	NotAlways    HideSoftInputFlags = 2
)

type LifecycleCallbacks

type LifecycleCallbacks struct {
	OnCreate                   func(*Activity)
	OnStart                    func(*Activity)
	OnResume                   func(*Activity)
	OnSaveInstanceState        func(*Activity, unsafe.Pointer)
	OnPause                    func(*Activity)
	OnStop                     func(*Activity)
	OnDestroy                  func(*Activity)
	OnWindowFocusChanged       func(*Activity, int32)
	OnNativeWindowCreated      func(*Activity, unsafe.Pointer)
	OnNativeWindowResized      func(*Activity, unsafe.Pointer)
	OnNativeWindowRedrawNeeded func(*Activity, unsafe.Pointer)
	OnNativeWindowDestroyed    func(*Activity, unsafe.Pointer)
	OnInputQueueCreated        func(*Activity, unsafe.Pointer)
	OnInputQueueDestroyed      func(*Activity, unsafe.Pointer)
	OnContentRectChanged       func(*Activity, unsafe.Pointer)
	OnConfigurationChanged     func(*Activity)
	OnLowMemory                func(*Activity)
}

LifecycleCallbacks holds Go callbacks for ANativeActivity lifecycle events.

type NativeActivityCallbacks

type NativeActivityCallbacks struct {
	// contains filtered or unexported fields
}

NativeActivityCallbacks wraps the NDK ANativeActivityCallbacks handle.

func NewNativeActivityCallbacksFromPointer

func NewNativeActivityCallbacksFromPointer(ptr unsafe.Pointer) *NativeActivityCallbacks

NewNativeActivityCallbacksFromPointer wraps a raw ANativeActivityCallbacks pointer.

func NewNativeActivityCallbacksFromUintPtr

func NewNativeActivityCallbacksFromUintPtr(ptr uintptr) *NativeActivityCallbacks

NewNativeActivityCallbacksFromUintPtr wraps a uintptr as a NativeActivityCallbacks. The caller must ensure ptr points to a valid ANativeActivityCallbacks.

func (*NativeActivityCallbacks) Pointer

func (h *NativeActivityCallbacks) Pointer() unsafe.Pointer

Pointer returns the underlying pointer as unsafe.Pointer.

func (*NativeActivityCallbacks) UintPtr

func (h *NativeActivityCallbacks) UintPtr() uintptr

UintPtr returns the underlying pointer as a uintptr. This is useful for interop with gomobile bind, golang.org/x/mobile, gioui.org, and other packages that represent native handles as uintptr.

type ShowSoftInputFlags

type ShowSoftInputFlags int32

const (
	Implicit ShowSoftInputFlags = 1
	Forced   ShowSoftInputFlags = 2
)
