CompletionInfo

public final class CompletionInfo
extends Object implements Parcelable

java.lang.Object
   ↳ android.view.inputmethod.CompletionInfo


Information about a single text completion that an editor has reported to an input method.

This class encapsulates a completion offered by an application that wants it to be presented to the user by the IME. Usually, apps present their completions directly in a scrolling list for example (UI developers will usually use or extend to implement this). However, in some cases, the editor may not be visible, as in the case in extract mode where the IME has taken over the full screen. In this case, the editor can choose to send their completions to the IME for display.

Most applications who want to send completions to an IME should use AutoCompleteTextView as this class makes this process easy. In this case, the application would not have to deal directly with this class.

An application who implements its own editor and wants direct control over this would create an array of CompletionInfo objects, and send it to the IME using displayCompletions(View, CompletionInfo[]). The IME would present the completions however they see fit, and call back to the editor through commitCompletion(CompletionInfo). The application can then pick up the commit event by overriding onCommitCompletion(CompletionInfo).

CompletionInfo(long id, int index, CharSequence text)

Create a simple completion with just text, no label.

CompletionInfo(long id, int index, CharSequence text, CharSequence label)

Create a full completion with both text and label.

Describe the kinds of special objects contained in this Parcelable instance's marshaled representation.

Return the abstract identifier for this completion, typically corresponding to the id associated with it in the original adapter.

CharSequence getLabel()

Return the user-visible label for the completion, or null if the plain text should be shown.

CompletionInfo

Added in API level 3
CompletionInfo (long id, 
                int index, 
                CharSequence text)

Create a simple completion with just text, no label.

Parameters
id long: An id that get passed as is (to the editor's discretion)
index int: An index that get passed as is. Typically this is the index in the list of completions inside the editor.
text CharSequence: The text that should be inserted into the editor when this completion is chosen.

CompletionInfo

Added in API level 3
CompletionInfo (long id, 
                int index, 
                CharSequence text, 
                CharSequence label)

Create a full completion with both text and label. The text is what will get inserted into the editor, while the label is what the IME should display. If they are the same, use the version of the constructor without a `label' argument.

Parameters
id long: An id that get passed as is (to the editor's discretion)
index int: An index that get passed as is. Typically this is the index in the list of completions inside the editor.
text CharSequence: The text that should be inserted into the editor when this completion is chosen.
label CharSequence: The text that the IME should be showing among the completions list.

Public methods

describeContents

Added in API level 3
int describeContents ()

Describe the kinds of special objects contained in this Parcelable instance's marshaled representation. For example, if the object will include a file descriptor in the output of writeToParcel(Parcel, int), the return value of this method must include the CONTENTS_FILE_DESCRIPTOR bit.

Returns
int a bitmask indicating the set of special object types marshaled by this Parcelable object instance.

getId

Added in API level 3
long getId ()

Return the abstract identifier for this completion, typically corresponding to the id associated with it in the original adapter.

Returns
long

getLabel

Added in API level 3
CharSequence getLabel ()

Return the user-visible label for the completion, or null if the plain text should be shown. If non-null, this will be what the user sees as the completion option instead of the actual text.

Returns
CharSequence

getPosition

Added in API level 3
int getPosition ()

Return the original position of this completion, typically corresponding to its position in the original adapter.

Returns
int

getText

Added in API level 3
CharSequence getText ()

Return the actual text associated with this completion. This is the real text that will be inserted into the editor if the user selects it.

Returns
CharSequence

toString

Added in API level 3
String toString ()

Returns a string representation of the object. In general, the toString method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.

The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:

 getClass().getName() + '@' + Integer.toHexString(hashCode())
 

Returns
String a string representation of the object.

writeToParcel

Added in API level 3
void writeToParcel (Parcel dest, 
                int flags)

Used to package this object into a Parcel.

Parameters
dest Parcel: The Parcel to be written.
flags int: The flags used for parceling.
