專注於列表視圖內錯誤編輯文本

當我嘗試點擊EditText裏面ListView項目。它獲得焦點和失去焦點，而調試，我發現，如果我點擊第21項，位置值改變像21,19,1,2等。不知道如果列表重新呈現自己或其他事情正在發生。我已經搜索了很多，並已嘗試配置ListView（beforeDescendants和afterDescendants）和Activity（adjustPan）。專注於列表視圖內錯誤編輯文本

我已經使用了我的自定義適配器。共享XML文件ListView和列表項以及適配器的java代碼。

最後，我想它了。該問題試圖解決在getview中get tex更改的值。這是重新呈現列表項目，我得到了錯誤的焦點和不同奇怪的行爲。我創建了一個textwatcher類，並在初始化對象時添加了它，以便它不會影響列表中每個項目的每次。以下是MyCustom適配器的代碼

插入此行之前onCreatesetContentView()

getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_MASK_ADJUST);

它一定會幫助你

我將您的建議代碼應用於我的應用程序，性能有所提高，但有時仍然不允許編輯框內的文本在輸入值時發生更改。 –

早些時候，我的代碼允許我在30-40個列表項中的一個或兩個編輯文本中輸入值，現在它允許我在大多數編輯文本中輸入值，但是當我上下滾動並嘗試在某些值中輸入值時隨機編輯文本，一次或兩次的值不反映。 –
