问题描述
在升级到Android Studio 3.1时,布局编辑器面板中没有TimePicker。
搜索找不到它。
实际上,所有选择器控件似乎都具有消失了。
他们在3.0版本中。
On upgrade to Android Studio 3.1 there is no TimePicker in the layout editor palette.
Search doesn't find it.
In fact all of the picker controls seem to have vanished.
They were there in 3.0.
推荐答案
我不确定在选择菜单中的哪里可以找到它,但是如果您只需要在项目中使用时间选择器,则可以选择 activity.xml
文件底部的 Text
标签,然后粘贴TimePicker xml。
I am not sure where to find it in the selection menu but if you just need a time picker in your project you can select the Text
tab on the bottom of your activity.xml
file and paste the TimePicker xml.
<TimePicker
android:id="@+id/simpleTimePicker"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:timePickerMode="spinner"/>
然后,您可以选择所需的 timePickerMode
如果您想要一个时钟,则将 spinner
更改为 clock
。
Then you can select which timePickerMode
you want if you want a clock then change spinner
with clock
.
希望这会有所帮助。
