我有一個ExpandableListView，我想填充我的NoteView類型的自定義視圖。 NoteView擴展了LinearLayout幷包含兩個按鈕和一個複選框。我幾乎一切正常，NoteView正在填充支持數據，列表正在填充，並且按鈕可點擊並執行所需的任務。如何使用按鈕實現自定義列表視圖行？
問題是ExpandableListView不再響應click/longclick/keypress事件（除了選擇帶軌跡球/ DPAD的列表項）。
我用標準的TextView替換了我的自定義視圖，觸摸事件再次正常流動，所以它幾乎可以肯定是我做錯了我的自定義視圖或我忽略的一些模糊的ListView設置。
這是我的NoteView代碼和XML佈局。我錯過了什麼？

我在開發早期有同樣的問題，並發現focusable =「false」是解決方案。然後，我將佈局更改爲自定義視圖，而不是直接的XML佈局，並忘記在我的所有實驗中再次執行此操作。我曾嘗試通過xml阻止後代的可聚焦性，但我從未進入單獨的按鈕進行焦點控制。謝謝，工作完美。 – CodeFusionMobile 2010-10-08 17:03:58
