详细描述

The QAndroidBinder is a convenience class that wraps the most important Android Binder 方法。

成员类型文档编制

enum QAndroidBinder:: CallType

此枚举用于 QAndroidBinder::transact () to describe the mode in which the IPC call is performed.

常量	值	描述
`QAndroidBinder::Normal`	`0`	normal IPC, meaning that the caller waits the result from the callee
`QAndroidBinder::OneWay`	`1`	one-way IPC, meaning that the caller returns immediately, without waiting for a result from the callee

成员函数文档编制

QAndroidBinder:: QAndroidBinder ()

创建可用于履行 IPC 的新对象。

另请参阅 onTransact and transact .

QAndroidBinder:: QAndroidBinder (const QAndroidJniObject & binder )

创建新的对象从 binder Java 对象。

另请参阅 transact .

`[虚拟]` QAndroidBinder:: ~QAndroidBinder ()

Destroys the instance of QAndroidBinder. The destructor is virtual.

QAndroidJniObject QAndroidBinder:: handle () const

The return value is useful to call other Java API which are not covered by this wrapper

`[虚拟]` bool QAndroidBinder:: onTransact ( int code , const QAndroidParcel & data , const QAndroidParcel & reply , QAndroidBinder::CallType flags )

Default implementation is a stub that returns false. The user should override this method to get the transact data from the caller.

The code 是要履行的动作。 data 是由调用者发送的编组数据。
The reply 是要发送给调用者的编组数据。
The flags 是额外操作标志。

警告： This method is called from Binder's thread which is different from the thread that this object was created.
