我怎樣才能把文本下每個imagaview

Question

在我的項目中我使用horizo​​ntalscrollview作爲按鈕的圖像。當我點擊圖像時，它顯示horizantalscrollview上方的圖像。我想要的是當我點擊它時在圖像下面顯示一個描述文字。任何人都可以幫忙嗎？

這是我的xml文件。

你可以做這樣的事情

TextView desc = (TextView)findViewById(R.id.Aciklama); 
desc.setText(DESCRIPTION); 

你做你與顯示器的ImageView做了什麼。在點擊時創建對textview和setText的引用。
