枚举 TileStatus

java.lang.Object

java.lang.Enum<TileStatus>

ohos.wearable.tile.TileStatus

所有已实现的接口:

ohos.utils.Sequenceable

public enum TileStatus
extends java.lang.Enum<TileStatus>
implements ohos.utils.Sequenceable

Enumerates states of a tile.

A tile has various states in its lifecycle. When the tile state changes, TileAbility#onStatusChanged(TileStatus) is called to notify the TileAbility, so that different operations are performed as defined.

枚举常量详细资料

TILE_PREPARE

public static final TileStatus TILE_PREPARE

Indicates that the tile is in the preparing state. Specifically, when a user selects a tile, the system automatically identifies the next possible tile to select and passes TILE_PREPARE to the TileAbility, so that the tile has time to prepare the data to display.

TILE_SELECTED

public static final TileStatus TILE_SELECTED

Indicates that the tile is in the selected state. Specifically, when a user selects the possible tile, the system passes TILE_SELECTED to the TileAbility, which returns the tile data to display.

TILE_HIDE

public static final TileStatus TILE_HIDE

Indicates that the tile is in the hidden state when a user releases the tile. In this case, the TileAbility should clear the data to reduce system load.

TILE_UPDATE

public static final TileStatus TILE_UPDATE

Indicates that the tile is in the updated state. In this case, a valid TileEntity object should be returned. The system passes TILE_UPDATE to the TileAbility in the following cases:

• This tile is added to the visible list.
• The TileAbility calls TileAbility#notifyDataChanged(Context, ElementName).
• The delay in updating this tile is set via TileEntity.Builder.setUpdateDelay(long) and the delay elapses.

PRODUCER

public static final ohos.utils.Sequenceable.Producer<TileStatus> PRODUCER

The creator of TileStatus.

方法详细资料

values

public static TileStatus[] values()

按照声明该枚举类型的常量的顺序, 返回 包含这些常量的数组。该方法可用于迭代 常量, 如下所示:

for (TileStatus c : TileStatus.values())
    System.out.println(c);

返回:

按照声明该枚举类型的常量的顺序返回的包含这些常量的数组

valueOf

public static TileStatus valueOf(java.lang.String name)

返回带有指定名称的该类型的枚举常量。 字符串必须与用于声明该类型的枚举常量的 标识符完全匹配。(不允许有多余 的空格字符。)

参数:

name - 要返回的枚举常量的名称。

返回:

返回带有指定名称的枚举常量

抛出:

java.lang.IllegalArgumentException - 如果该枚举类型没有带有指定名称的常量

java.lang.NullPointerException - 如果参数为空值

marshalling

public boolean marshalling(ohos.utils.Parcel parcel)

指定者:

marshalling 在接口中 ohos.utils.Sequenceable

unmarshalling

public boolean unmarshalling(ohos.utils.Parcel parcel)

指定者:

unmarshalling 在接口中 ohos.utils.Sequenceable
