Properties
BridgeClassName
Java class name to be instantiated
public override string BridgeClassName { get; }Property Value
IGNORE_ITEM_VIEW_TYPE
public static int IGNORE_ITEM_VIEW_TYPE { get; set; }Property Value

OnGetAutofillOptions
Handler for https://developer.android.com/reference/android/widget/Adapter.html#getAutofillOptions()
public Func<CharSequence[]> OnGetAutofillOptions { get; set; }Property Value
- Func<CharSequence[]>
Remarks
Assign a delegate to handle the event without subclassing. If both this handler and a virtual method override are present, the delegate takes precedence. Set to null to delegate to the virtual method.
OnGetAutofillOptionsDispose
Optional handler invoked after the event handler returns, to dispose the JVM object returned by this event.
public Action<CharSequence[]> OnGetAutofillOptionsDispose { get; set; }Property Value
Remarks
Set OnGetAutofillOptionsDispose when the event handler returns a JVM-backed object that is no longer needed after the call. The handler receives the return value and is responsible for calling Dispose() on it, releasing the underlying JVM global reference immediately instead of waiting for the .NET garbage collector to finalize it. If not set, the return value is not disposed automatically.
OnGetCount
public Func<int> OnGetCount { get; set; }Property Value
Remarks
Assign a delegate to handle the event without subclassing. If both this handler and a virtual method override are present, the delegate takes precedence. Set to null to delegate to the virtual method.

If not set, the return value is not disposed automatically.
OnGetItem
public Func<int, object> OnGetItem { get; set; }Property Value
Remarks

Methods
GetAutofillOptions()
public virtual CharSequence[] GetAutofillOptions()Returns
Remarks

GetAutofillOptionsDefault()
public CharSequence[] GetAutofillOptionsDefault()Returns
Remarks
The method invokes the default implementation in the JVM interface
GetCount()
public virtual int GetCount()Returns
GetItem(int)
public virtual object GetItem(int arg0)Parameters
Returns
GetItemId(int)
public virtual long GetItemId(int arg0)Parameters

public virtual int GetItemViewType(int arg0)Parameters
Returns
GetView(int, View, ViewGroup)
public virtual View GetView(int arg0, View arg1, ViewGroup arg2)Parameters
Returns
GetViewTypeCount()
public virtual int GetViewTypeCount()Returns
HasStableIds()
public virtual bool HasStableIds()Returns
InitializeHandlers(Type)
Handlers initializer for Adapter
protected virtual void InitializeHandlers(Type listenerRuntimeType)Parameters
listenerRuntimeTypeType
IsEmpty()
public virtual bool IsEmpty()Returns
ListenerShallManageEvent(int)
Invoked from the JVMBridgeListener on each received event to notify the user which can decide to abort the execution for the specific event returning false
protected override bool ListenerShallManageEvent(int eventIndex)Parameters
eventIndexintThe index of the event triggered as returned from AddEventHandler(string, EventHandler) or AddEventHandler<TDataClass>(string, EventHandler<CLRListenerEventArgs<TDataClass>>)
Returns
Remarks
By default every event continues the execution and reads the data from JVM; this implies an extra cost which can be limited using ListenerShallManageEvent(int) or the ListenerShallManageEventIndex/ListenerShallManageEventName handlers. Returning false the control is immediately returned to the JVM, anyway the user has received the notification. It can be useful in scenarios where the user is interested in few events and the other are simply discarded to optimize the execution speed. By default, this function invokes ListenerShallManageEventIndex, then try ListenerShallManageEventName if they are set or return true
ListenerShallManageEventHandlers(int)
protected virtual bool ListenerShallManageEventHandlers(int eventIndex)Parameters
eventIndexint
