当我获得许可结果时,我正在尝试启动新活动,但是即使调用了startActivity也没有任何反应
import 'date-fns';
import React from 'react';
import Grid from '@material-ui/core/Grid';
import DateFnsUtils from '@date-io/date-fns';
import {
MuiPickersUtilsProvider,
KeyboardTimePicker,
KeyboardDatePicker,
} from '@material-ui/pickers';
export default function MaterialUIPickers() {
// The first commit of Material-UI
const [selectedDate, setSelectedDate] = React.useState(new Date('2014-08-18T21:11:54'));
const handleDateChange = date => {
setSelectedDate(date);
};
return (
<MuiPickersUtilsProvider utils={DateFnsUtils}>
<Grid container justify="space-around">
<KeyboardDatePicker
disableToolbar
variant="inline"
format="MM/dd/yyyy"
margin="normal"
id="date-picker-inline"
label="Date picker inline"
value={selectedDate}
onChange={handleDateChange}
KeyboardButtonProps={{
'aria-label': 'change date',
}}
/>
</Grid>
</MuiPickersUtilsProvider>
);
}
日志中未显示错误消息
看起来好像新活动在屏幕上,但是我可以单击按钮,因此“不可见”。
