我正在处理用户可以设置日期和时间的应用程序.我想在单个对话片段中设置日期和时间,并将其设置为编辑文本.可以在1个对话片段中使用日期和时间选择器吗?如果是这样,你怎么做?
目前,我正在从对话片段中获取时间,然后将其设置为EditText.
目前,我正在从对话片段中获取时间,然后将其设置为EditText.
我的代码是
LaterTextView=(TextView)findViewById(R.id.PickUp_later_TextView); LaterTextView.setOnClickListener(new View.OnClickListener() { @SuppressWarnings("deprecation") public void onClick(View v) { showDialog(TIME_DIALOG_ID); } }); } protected Dialog onCreateDialog(int id) { switch (id) { case TIME_DIALOG_ID: // set time picker as current time return new TimePickerDialog(this,timePickerListener,hour,minute,false); } return null; } private TimePickerDialog.OnTimeSetListener timePickerListener = new TimePickerDialog.OnTimeSetListener() { public void onTimeSet(TimePicker view,int selectedHour,int selectedMinute) { hour = selectedHour; minute = selectedMinute; // set current time into TextView setDate_time_EditTExt.setText(new StringBuilder().append(pad(hour)) .append(":").append(pad(minute))); } }; private static String pad(int c) { if (c >= 10) return String.valueOf(c); else return "0" + String.valueOf(c); }
我想从相同的对话框片段设置日期和时间.
解决方法
日期选择器和时间选择器都在单个对话框中.检查这个代码.
