從android的另一個類訪問VideoView

Question

我想從另一個類訪問videoview。如果我這樣做得到例外

Only the original thread that created a view hierarchy can touch its views.

任何人都可以告訴我如何從另一個類訪問視圖？

Answer 1

您可以使用以下方法訪問該視圖。

runOnUiThread(Runnable ac) 

爲此，將視圖所在的活動傳遞給類。

如：

activity.runOnUiThread(new Runnable() { 
    public void run() { 

    //access here 

    } 
});
