Output

輸出量

After executing your code, you get an image. Actually this is not only an image, but a button containing an image. As you click on the image button a toast message is displayed as “You Clicked Image Button”.

執(zhí)行代碼后，您將得到一張圖像。 實(shí)際上，這不僅是圖像，而且是包含圖像的按鈕。 當(dāng)您單擊圖像按鈕時(shí)，烤面包消息將顯示為“您單擊圖像按鈕”。
