构造器详细资料

FractionAbility

public FractionAbility()

方法详细资料

getFractionManager

public FractionManager getFractionManager()

Obtains the FractionManager for managing fractions in this ability.

返回:

Returns the FractionManager instance.

从以下版本开始:

4

onPostStart

protected void onPostStart(PacMap pacMap)

Called when the ability has been started by calling onStart(ohos.aafwk.content.Intent) and onRestoreAbilityState(ohos.utils.PacMap).

Generally, this method is used for system classes to perform final initialization operations after an application starts. You do not need to implement this method for your application. When overriding this method, you must call the implementation of its parent class. Otherwise, an exception will be thrown.

覆盖:

onPostStart 在类中 Ability

参数:

pacMap - Indicates the data most recently provided in onSaveAbilityState(ohos.utils.PacMap).

从以下版本开始:

4

onStart

protected void onStart(Intent intent)

Called back when an ability is started for initialization (it can be called only once in the entire lifecycle of an ability).

Most initialization operations should be performed by calling this method. For example, you can use the current method to call Ability.setMainRoute(java.lang.String) and Ability.addActionRoute(java.lang.String,java.lang.String) to set the main router and action router for a Page ability.

覆盖:

onStart 在类中 Ability

参数:

intent - Indicates information carried when this ability is started. Note: For a Service ability, null is passed.

从以下版本开始:

4

onActive

protected void onActive()

Called back when an ability enters the ACTIVE state.

The ability in the ACTIVE state is in the foreground and is interactive.

覆盖:

onActive 在类中 Ability

从以下版本开始:

4

onBackground

protected void onBackground()

Called back when an ability enters the BACKGROUND state.

A Page ability in the BACKGROUND state is invisible. You are advised to suspend threads related to the ability and clear some resources to free up system memory.

覆盖:

onBackground 在类中 Ability

从以下版本开始:

4

onInactive

protected void onInactive()

Called back when an ability enters the INACTIVE state (an ability in this state is not interactive and may change to the BACKGROUND or ACTIVE state).

INACTIVE is an intermediate state and does not last for a long period of time. Frequent switching between ACTIVE and INACTIVE is possible. Therefore, you can use this method to perform certain simple operations, for example, committing any changes.

覆盖:

onInactive 在类中 Ability

从以下版本开始:

4

onStop

protected void onStop()

Called back before an ability is destroyed.

This method indicates the end of the ability lifecycle. It can be executed after the ability calls the Ability.terminateAbility() method or the last ability slice of the ability calls the AbilitySlice#terminate() method. Generally, this method is used to clear resources.

覆盖:

onStop 在类中 Ability

从以下版本开始:

4

onForeground

protected void onForeground(Intent intent)

Called back when the state of an ability changes from BACKGROUND to INACTIVE.

This is an intermediate state callback method. Generally, the system calls this method to refresh data status and then calls back the onActive() method.

覆盖:

onForeground 在类中 Ability

参数:

intent - Indicates information carried when the ability returns to the INACTIVE state.

从以下版本开始:

4

onSaveAbilityState

public void onSaveAbilityState(PacMap outState)

Saves temporary data and states of this ability. This method should be implemented by a Page ability.

This method is called when the system determines that the ability may be destroyed in an unexpected situation, for example, when the screen orientation changes or the user touches the Home key. Generally, this method is used only to save temporary states.

覆盖:

onSaveAbilityState 在类中 Ability

参数:

outState - Indicates the PacMap object used for storing user data and states. This parameter cannot be null.

从以下版本开始:

4

onRestoreAbilityState

public void onRestoreAbilityState(PacMap inState)

Restores data and states of an ability when it is restored by the system. This method should be implemented by a Page ability.

This method is called if an ability was destroyed at a certain time due to resource reclaim or was unexpectedly destroyed and the onSaveAbilityState(ohos.utils.PacMap) method was called to save its user data and states. Generally, this method is called after the onStart(ohos.aafwk.content.Intent) method.

覆盖:

onRestoreAbilityState 在类中 Ability

参数:

inState - Indicates the PacMap object used for storing data and states. This parameter can not be null.

从以下版本开始:

4

onBackPressed

protected void onBackPressed()

Called back when the Back key is pressed.

The default implementation destroys the ability. You can override this method.

覆盖:

onBackPressed 在类中 Ability

从以下版本开始:
