問題描述
我有一個顯示時間的 EditText.用戶單擊 EditText 后，我想顯示一個 TimePickerDialog，因此我將 View.OnClickListener 設置為我的 EditText.
I have an EditText that shows time. After user clicks the EditText I want to show a TimePickerDialog, so I set a View.OnClickListener to my EditText.
但是 OnClickListener 的行為很奇怪 - 我觸摸 EditText 然后出現軟件鍵盤(我不想要).當我再次觸摸時， OnClickListener.onClick() 終于被調用并出現對話框.
But the OnClickListener is behaving weirdly - I touch the EditText and then software keyboard appears (which I don't want). When I touch again, OnClickListener.onClick() is finally called and the dialog appears.
如果我想讓對話框立即出現怎么辦?
What should I do if I want the dialog to appear immediately?
推薦答案
與大多數其他控件不同，EditText 在系統處于觸摸模式"時是可聚焦的.第一個單擊事件聚焦控件，而第二個單擊事件實際上觸發 OnClickListener.如果您使用 android:focusableInTouchMode View 屬性禁用觸摸模式焦點，則 OnClickListener 應該會按預期觸發.
Unlike most other controls, EditTexts are focusable while the system is in 'touch mode'. The first click event focuses the control, while the second click event actually fires the OnClickListener. If you disable touch-mode focus with the android:focusableInTouchMode View attribute, the OnClickListener should fire as expected.
<EditText
android:text="@+id/EditText01"
android:id="@+id/EditText01"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:focusableInTouchMode="false" />
