时间选择器显示时间为 4:7 而不是 04:07

我有一个时间选择器功能，可以在 EditText 中设置时间。但它显示的格式不合适。例如 04:07pm 显示为 4:7。当时间中的数字小于 10 时，它会自动删除 0。 请帮帮我。 我的代码是

        if (v == btnTimePicker1)
               {

                // Process to get Current Time
                final Calendar c = Calendar.getInstance();
                mHour = c.get(Calendar.HOUR_OF_DAY);
                mMinute = c.get(Calendar.MINUTE);

                // Launch Time Picker Dialog
                TimePickerDialog tpd = new TimePickerDialog(this,
                        new TimePickerDialog.OnTimeSetListener() {

                            @Override
                            public void onTimeSet(TimePicker view, int hourOfDay,
                                    int minute) {
                                // Display Selected time in textbox
                                txtTime1.setText(hourOfDay + ":" + minute);
                            }
                        }, mHour, mMinute, false);
                tpd.show();




            }

只需更改该行：

txtTime1.setText(hourOfDay + ":" + minute);

to:

txtTime1.setText(String.format("%02d:%02d", hourOfDay, minute));

一切都会好起来的。

如果您想要 12 小时制而不是 24 小时制，请将该行替换为以下内容：

int hour = hourOfDay % 12;
if (hour == 0)
    hour = 12;
txtTime1.setText(String.format("%02d:%02d %s", hour, minute, 
                               hourOfDay < 12 ? "am" : "pm"));

或者你只需​​两行即可完成：

int hour = hourOfDay % 12;    
txtTime1.setText(String.format("%02d:%02d %s", hour == 0 ? 12 : hour,
                               minute, hourOfDay < 12 ? "am" : "pm"));
