Android Reveal Animation開始一項活動

Question

如何在兩個活動之間使用Reveal Animation？ 有很多關於如何使用它來啟動Activity內部視圖的信息和示例，但是我想單擊一個按鈕並啟動一個Reveal Animation來打開下一個Activity。 我嘗試在第一個布局中包含第二個布局並將其設置為Invisible，然后在單擊按鈕時顯示它。 但它不能正常工作。 我想知道我是否可以簡單地將Reveal動畫定義為XML，但我不知道該怎么做。 謝謝

Reveal Effect對我的活動和片段成功起作用也應用下面的代碼來設置揭示對活動或片段的影響。 刪除注釋以使用代碼下方的特定動畫表單。

例如，您可以為活動的父布局設置動畫。 這是一個可能對您有幫助的答案。 它在活動中消失，但如果您了解它的完成方式，您可以應用任何動畫。

淡入Android啟動活動

要取消活動動畫中內置的標准，您可以使用此Intent.FLAG ：

intent.setFlag(Intent.FLAG_ACTIVITY_NO_ANIMATION);

當你開始你的活動。
