给定 XML：我正在准备布局，但在线性布局中，我显示 2 个线性布局，内部显示时间选择器，但在这种情况下，它只显示时间选择

器和时间选择器的小时，而我必须显示小时，分钟上午和下午，但我无法做到这一点，请帮助如何修复它

Answer 1

@Override
    public void onClick(View v) {
        // TODO Auto-generated method stub
        if (v.getId() == R.id.imageView1) {
            Calendar mcurrentTime = Calendar.getInstance();
            int hour = mcurrentTime.get(Calendar.HOUR_OF_DAY);
            int minute = mcurrentTime.get(Calendar.MINUTE);
            TimePickerDialog mTimePicker;
            mTimePicker = new TimePickerDialog(MainActivity.this,
                    new TimePickerDialog.OnTimeSetListener() {
                        @Override
                        public void onTimeSet(TimePicker timePicker,
                                int selectedHour, int selectedMinute) {
                            Toast.makeText(MainActivity.this,
                                    selectedHour + ":" + selectedHour, 1000)
                                    .show();
                        }
                    }, hour, minute, true);// Yes 24 hour time
            mTimePicker.setTitle("Select Time");
            mTimePicker.show();
        }
    }

像这样使用，它将正常工作，并且很容易.

Answer 2

您可以使用它将其设置为 12h 格式

timePicker = (TimePicker) findViewById(R.id.timePicker1);
timePicker.setIs24HourView(false);
timePicker.setCurrentHour(Calendar.get(Calendar.HOUR_OF_DAY));
