isViewFromObject(View?view,?Object?object)

Determines whether a page View is associated with a specific key object as returned by?instantiateItem(ViewGroup, int). This method is required for a PagerAdapter to function properly.

Parameters

view :?Page View to check for association with?object ? ?

object :?Object to check for association with?view ? ?

Returns?

true if?view?is associated with the key object?object

以上是官方文檔解析。大概的意思就是判斷適配器的某個視圖頁面是否需要關聯一個特殊的對象并作為一個實例項目返回。

如果判斷為true ， 就將view 關聯到一個 object 對象。?

可能就是說你pagerAdapter選中的內容是不是當成一個對象來處理的意思吧。英文不好，不怎么能理解透。
