android:imeOptions屬性

默認情況下軟鍵盤右下角的按鈕爲“下一個”，點擊會到下一個輸入框，保持軟鍵盤

設置 android:imeOptions="actionDone" ，軟鍵盤下方變成“完成”，點擊後光標保持在原來的輸入框上，並且軟鍵盤關閉

android:imeOptions="actionSend" 軟鍵盤下方變成“發送”，點擊後光標移動下一個

在這裏設置的imeOptions如何使用呢？如下面的代碼，讓EditText實現setOnEditorActionListener，在onEditAction方法中actionId就對應我們設置的imeOptions。系統默認的actionId有：EditorInfo.IME_NULL、EditorInfo.IME_ACTION_SEND、EditorInfo.IME_ACTION_DONE等。這樣我們就可以根據不同的EditText來實現不同的軟鍵盤右下角功能鍵。
