问题描述
我有一个显示时间的 EditText.用户单击 EditText 后，我想显示一个 TimePickerDialog，因此我将 View.OnClickListener 设置为我的 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 的行为很奇怪 - 我触摸 EditText 然后出现软件键盘(我不想要).当我再次触摸时， OnClickListener.onClick() 终于被调用并出现对话框.
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.
如果我想让对话框立即出现怎么办?
What should I do if I want the dialog to appear immediately?
推荐答案
与大多数其他控件不同，EditText 在系统处于触摸模式"时是可聚焦的.第一个单击事件聚焦控件，而第二个单击事件实际上触发 OnClickListener.如果您使用 android:focusableInTouchMode View 属性禁用触摸模式焦点，则 OnClickListener 应该会按预期触发.
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" />
