如何在屏幕上垂直居中android TimePicker ?



考虑以下布局:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<TimePicker
android:layout_width="match_parent"
android:layout_height="match_parent"
android:timePickerMode="spinner" />
</LinearLayout>

TimePicker位于屏幕顶部,我想将其垂直居中。

例如,对于TextView,我将添加android:gravity="center",但它不适用于TimePicker

有办法吗?

你需要设置width &TimePicker的高度设置为wrap_content,以便将LinearLayoutandroid:gravity="center"居中

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center"
android:orientation="vertical">
<TimePicker
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:timePickerMode="spinner" />
</LinearLayout>
