我必须以hh:mm格式显示时间选择器点击编辑文本。所以我使用了下面的代码。
MainActivity.java:
e6.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
SimpleDateFormat sdf = new SimpleDateFormat("hh:mm");
Calendar mcurrentTime = Calendar.getInstance();
int hour = mcurrentTime.get(Calendar.HOUR_OF_DAY);
int minute = mcurrentTime.get(Calendar.MINUTE);
TimePickerDialog mTimePicker;
mTimePicker = new TimePickerDialog(AddFlight.this, new TimePickerDialog.OnTimeSetListener() {
@Override
public void onTimeSet(TimePicker timePicker, int selectedHour, int selectedMinute) {
e6.setText(selectedHour + ":" + selectedMinute);
}
}, hour, minute, true);//Yes 24 hour time
mTimePicker.setTitle("Select Time");
mTimePicker.show();
}
});
它运行良好并显示时间选择器。但是我的问题是,当我选择时间戳中的04:15时,它显示为4:15。它之前不包含0我需要用hh:mm格式显示时间选择器。
任何人都可以帮助我。谢谢。

刚才我引用了这个post并更改了单行:
这一行
e6.setText(selectedHour +":" + selectedMinute);
到
e6.setText(String.format("%02d:%02d",selectedHour, selectedMinute));
答案 1 :(得分:2)
只需将文字设置为"%02d:%02d"如下:
e6.setText(String.format("%02d:%02d", selectedHour, selectedMinute));
希望这可能会对你有所帮助

你可以尝试这种方式......
mTimePicker = new TimePickerDialog(AddFlight.this, new TimePickerDialog.OnTimeSetListener() {
@Override
public void onTimeSet(TimePicker timePicker, int selectedHour, int selectedMinute) {
String formattedTime = "";
String sHour = "00";
// converting hour to tow digit if its between 0 to 9. (e.g. 7 to 07)
if(selectedHour < 10)
sHour = "0"+selectedHour;
else
sHour = String.valueOf(selectedHour);
e6.setText(sHour + ":" + selectedMinute);
}
}, hour, minute, true);

只需使用此方法,
private String getDD(int num) {
return num > 9 ? "" + num : "0" + num;
}
