In View Pager只顯示最後一張圖片來自Json反覆在android

-1

我有問題顯示圖像的圖像滑塊android.I從JSON獲取圖像，但始終只顯示索引的最後一個圖像，假設如果我可以移動在Android中一次又一次查看傳呼機相同的圖像並顯示圖像滑動。我不知道是什麼問題，我幾乎盡我所能，但我真的找不到那個錯誤。任何人都可以幫助解決我的問題。In View Pager只顯示最後一張圖片來自Json反覆在android

你能解釋一下爲什麼你要使用'HashMap'的'ArrayList'而不是你使用'String'的'ArrayList'並且按位置獲得'image'。 –

你的代碼中的問題是你對每個圖像使用相同的'IMAGE_TAG'，所以添加到'HashMap'中的最後一個圖像將會顯示 –

在我不使用HashMap之前，我使用了模型來設置和獲取圖像，但是那一個也是我得到了相同的圖像 – Nivethitha

您可以更改ArrayList<HashMap<String,String>>到ArrayList<String>，因爲它似乎HashMap不需要從您的代碼。

接下來你for循環中，您在其中添加圖像路徑HashMap，而不是直接添加到ArrayList，

然後在getView()您PagerAdapter使用slideShowImages.get(position)得到ArrayList<>圖像，

感謝哥們，真的非常感謝，我犯了小錯誤讓我頭疼。 – Nivethitha

現在satyen工作很好。 – Nivethitha
