SRY，我的英語.. 從Home_Activity我的應用程序，我點擊一個按鈕和一個自定義AlertDialog顯示出來。在這個AlertDialog（DialogAdd）中，我點擊一個ImageView說iv1（或ImageButton - 都沒有工作），另一個自定義AlertDialog打開（選擇） - 迄今爲止這麼好。現在我打開了第二個AlertDialog，並看到了4張小圖片。當我點擊這些圖片之一時，第二個AlertDialog應該關閉，並且ImageView（iv1）應該更改爲從AlertDialog 2中選擇圖標。我得到了一切正在運行，但不能更改此ImageView/ImageButton ... 我分離了此行爲到一個小應用程序..不能在自定義AlertDialog內得到定製AlertDialog一個ImageView的，更新的

我和無效ib_dialog_smile試了一下，我用了一個ImageButton的，也ImageView的，AppCompatImageView，setImageDrawable，setImageResource ..但圖像沒有得到更新。 有人可以幫我改變ib_dialog_smile的形象嗎？
謝謝！
