try this code:
试试这个代码：
TimePickerFragment timePickerFragment = new TimePickerFragment();
timePickerFragment.setOnTimeSetListener(new OnTimeSetListener() {
public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
Calendar datetime = Calendar.getInstance();
Calendar c = Calendar.getInstance();
datetime.set(Calendar.HOUR_OF_DAY, hourOfDay);
datetime.set(Calendar.MINUTE, minute);
if (datetime.getTimeInMillis() >= c.getTimeInMillis()) {
//it's after current
int hour = hourOfDay % 12;
btnPickStartTime.setText(String.format("%02d:%02d %s", hour == 0 ? 12 : hour,
minute, hourOfDay < 12 ? "am" : "pm"));
} else {
//it's before current'
Toast.makeText(getApplicationContext(), "Invalid Time", Toast.LENGTH_LONG).show();
}
}
});
timePickerFragment.show(getSupportFragmentManager(), "TIME");
it will show the timepickerdialog and if user select any time before current time... it will show invalid time..
它将显示timepicker对话框，如果用户选择当前时间之前的任何时间...它将显示无效时间..

The best solution for you will be to use thismaterial design library to pick time or date and set min value.
对您来说最好的解决方案是使用这个材料设计库来选择时间或日期并设置最小值。
TimePickerDialog tpd = TimePickerDialog.newInstance(
new TimePickerDialog.OnTimeSetListener() {
@Override
public void onTimeSet(TimePickerDialog view, int hourOfDay, int minute, int second) {
//put some interesting code
}
},
now.get(Calendar.HOUR_OF_DAY),
now.get(Calendar.MINUTE),
true
);
tpd.setMinTime(10, 0, 0); // MIN: hours, minute, secconds
tpd.show(getFragmentManager(), "TimePickerDialog");
The easiest way to add the Material DateTime Picker library to your project is by adding it as a dependency to your build.gradle
将 Material DateTime Picker 库添加到您的项目的最简单方法是将其作为依赖项添加到您的 build.gradle
dependencies {
compile 'com.wdullaer:materialdatetimepicker:3.0.0'
}
Hope this will help you.
希望这会帮助你。
