如何在上午和下午显示时间选择器？ [英] How to display time picker with am and pm?

问题描述

EditText time = (EditText) findViewById(R.id.time);

time.setOnLongClickListener(new OnLongClickListener(){
    @Override
    public boolean onLongClick(View v) {
	// TODO Auto-generated method stub
	Calendar mcurrentTime = Calendar.getInstance();
	int hour = mcurrentTime.get(Calendar.HOUR_OF_DAY);
	int minute = mcurrentTime.get(Calendar.MINUTE);
	TimePickerDialog mTimePicker;
	            
	mTimePicker = new TimePickerDialog(AddEventsActivity.this, new TimePickerDialog.OnTimeSetListener() {

	      @Override
	      public void onTimeSet(TimePicker timePicker, int selectedHour, int selectedMinute) {
	         time.setText( selectedHour + ":" + selectedMinute);
	        }
	 }, hour, minute, true);//Yes 24 hour time
	            
	 mTimePicker.setTitle("Select Time");
	 mTimePicker.show();

	 return false;
         }
});

上面的代码显示24小时制，同时长按编辑文本。但是，我想要12小时制（即上午和下午）。



我应该在这段代码中更改什么？还有其他方法吗？

The above code display 24 hour clock while long click on edit text. But, I want 12 hour clock (i.e. with am and pm).

What should I change in this code? Is there any other way?

推荐答案

将TimePickerDialog中的true更改为false

change the true in TimePickerDialog to false

mTimePicker = new TimePickerDialog(AddEventsActivity.this, new TimePickerDialog.OnTimeSetListener() {...}, hour, minute, false);

参考：TimePickerDialog [ ^ ]

正如Mr.Peter Leow所说，将TimePickerDialog中的true更改为false将显示am和pm的时间选择器。但价值回报将在24小时内完成。所以我们必须检查返回的时间并以12小时时钟格式更改时间。

As Mr.Peter Leow told, changing true in TimePickerDialog to false will display time picker with am and pm. But the value return will be in 24 hour time. So we have to check the returned time and change the time in 12 hour clock format.

<pre>
EditText time = (EditText) findViewById(R.id.time);

time.setOnLongClickListener(new OnLongClickListener(){
        @Override
	public boolean onLongClick(View v) {
	// TODO Auto-generated method stub
	Calendar mcurrentTime = Calendar.getInstance();
	int hour = mcurrentTime.get(Calendar.HOUR_OF_DAY);
	int minute = mcurrentTime.get(Calendar.MINUTE);
	TimePickerDialog mTimePicker;
	            
	mTimePicker = new TimePickerDialog(AddEventsActivity.this, new TimePickerDialog.OnTimeSetListener() {
	     @Override
	     public void onTimeSet(TimePicker timePicker, int selectedHour, int selectedMinute) {
	                	
	        String am_pm;
	        if (selectedHour > 12)
	          {
	             selectedHour = selectedHour - 12;
	             am_pm = "PM";
	             } else {
	             am_pm = "AM";
	          }
	                	
	      time.setText( selectedHour + ":" + selectedMinute + " " +am_pm);
	     }
	     }, hour, minute, false);
	     mTimePicker.setTitle("Select Time");
	     mTimePicker.show();
             return false;
            }
});
