加載中
當(dāng)內(nèi)容加載時，如果界面是空白或靜態(tài)圖片佣耐，用戶就會以為你的應(yīng)用程序卡住了。這會導(dǎo)致困惑和失望，并可能導(dǎo)致人們離開你的應(yīng)用程序憋沿。
當(dāng)處于加載狀態(tài)時汞扎，要把加載正在進行中的信息傳達給用戶季稳。最起碼要展示一個活動轉(zhuǎn)輪表示加載正在進行中。更進一步的話澈魄，可以展示出明確的進度景鼠，這樣用戶就可以估計他們將等待多久。
盡快顯示內(nèi)容痹扇。不要讓人們等到內(nèi)容加載后才看到他們期望的界面铛漓。立即顯示界面，并使用占位符文本鲫构、圖形或動畫來標識尚未加載成功的內(nèi)容票渠。當(dāng)內(nèi)容加載成功后再將這些占位符元素替換為內(nèi)容展示給用戶。只要有可能芬迄，就在后臺預(yù)加載即將到來的內(nèi)容问顷，比如在播放動畫或用戶在瀏覽某一級頁面或菜單時。
教育或娛樂人們以掩蓋加載時間（以免用戶在這段加載時間中離開）《耪可以考慮顯示關(guān)于游戲玩法肠骆、有趣的視頻序列或有趣的占位符圖形。

自定義加載界面塞耕。雖然標準的進度指標通常是可以的蚀腿，但有時會讓人感覺脫離了上下文。這時可以考慮通過自定義動畫和與應(yīng)用程序或游戲風(fēng)格匹配的元素來設(shè)計一種更身臨其境的體驗扫外。

Loading
When content is loading, a blank or static screen can make it seem like your app is frozen, resulting in confusion and frustration, and potentially causing people to leave your app.
Make it clear when loading is occurring.?At minimum, show an activity spinner that communicates something is happening. Even better, display explicit progress so users can gauge how long they’ll be waiting.
Show content as soon as possible.?Don’t make people wait for content to load before seeing the screen they're expecting. Show the screen immediately, and use placeholder text, graphics, or animations to identify where content isn't available yet. Replace these placeholder elements as the content loads. Whenever possible, preload upcoming content in the background, such as while an animation is playing or the user is navigating a level or menu.
Educate or entertain people to mask loading time.?Consider showing hints about gameplay, entertaining video sequences, or interesting placeholder graphics.

Customize loading screens.?Although standard progress indicators are usually OK, they can sometimes feel out of context. Consider designing a more immersive experience through custom animations and elements that match the style of your app or game.
