打开时间/日期按钮点击谷歌日历 [英] open time/datePicker on button click like google Calendar does
问题描述
所以我想要一个时间和日期选择器弹出，当我点击一个按钮看谷歌日历做，当你按下右下角的fab按钮。将有一个新窗口显示日期和时间，当您点击其中一个时，选择器打开。
我不知道我是否需要创建一个片段有一个时间选择器，只是使尺寸更小，或者我必须通过代码创建一个。
这是我的代码： / p>
public class NewEventActivity扩展AppCompatActivity {
private LayoutInflater inflater;
private String [] arraySpinner;
private Button date_from;
private Button date_to;
private Button time_from;
private Button time_to;
私人EditText标题;
私人EditText邀请;
protected void onCreate（Bundle savedInstanceState）{
super.onCreate（savedInstanceState）;
setContentView（R.layout.new_event_fragment）;
findviewbyids（）;
initPickers（）;
}
public void findviewbyids（）{
date_from =（Button）findViewById（R.id.bt_date_from）;
time_from =（Button）findViewById（R.id.bt_time_from）;
date_to =（Button）findViewById（R.id.bt_date_to）;
time_to =（Button）findViewById（R.id.bt_time_to）;
title =（EditText）findViewById（R.id.et_title）;
invite =（EditText）findViewById（R.id.et_invite）;
}
public void initPickers（）{
Date today = new Date（）;
DateFormat df = new SimpleDateFormat（MM / dd / yyyy）;
DateFormat tf = new SimpleDateFormat（HH：mm：ss）;
String reportDate = df.format（今天）;
String reportTime = tf.format（今）;
date_from.setText（reportDate）;
time_from.setText（reportTime）;
date_to.setText（reportDate）;
time_to.setText（reportTime）;
date_from.setVisibility（View.VISIBLE）;
date_to.setVisibility（View.VISIBLE）;
time_from.setVisibility（View.VISIBLE）;
time_to.setVisibility（View.VISIBLE）;
date_from.setBackgroundColor（Color.TRANSPARENT）;
date_to.setBackgroundColor（Color.TRANSPARENT）;
time_from.setBackgroundColor（Color.TRANSPARENT）;
time_to.setBackgroundColor（Color.TRANSPARENT）;
Spinner group =（Spinner）findViewById（R.id.sp_group）;
this.arraySpinner = new String [] {
1，2，3，4，5
};
ArrayAdapter< String> adapter = new ArrayAdapter< String>（this，
android.R.layout.simple_spinner_item，arraySpinner）;
group.setAdapter（adapter）;
date_from.setOnClickListener（new View.OnClickListener（）{
@Override
public void onClick（View v）{
}
}）;
}
}
现在，当我点击 date_from 按钮时，datePicker应该出现，并且在设置日期之后，应该覆盖 date_from
上的文本我希望你能得到我的意思
更新：
好的，我解决了这样：
@Override
protected Dialog onCreateDialog（int id）{
/ / TODO自动生成的方法stub
if（id == 999）{
df.format（today）;
month = today.getMonth（）;
year = today.getYear（）;
day = today.getDay（）;
DatePickerDialog dlg = new DatePickerDialog（this，myDateListener，year，month，day）;
return dlg;
}
返回null;
}
private DatePickerDialog.OnDateSetListener myDateListener = new DatePickerDialog.OnDateSetListener（）{
@Override
public void onDateSet（DatePicker arg0，int arg1，int arg2，int arg3）{
year = arg1;
month = arg2;
day = arg3;
日期date =新日期（年，月，日）;
df.format（date）;
reportDate = df.format（date）;
date_from.setText（reportDate）;
}
};
现在我遇到这个问题：
不知何故当弹出对话框时，会告诉我年116，而我们有星期五的第三。
当我选择一个日期，例如6.10.2016我的按钮显示3800/00/06
所以这意味着它只得到正确的一天。
但为什么？
这样的事情 http：//www.tutorialspoint .com / android / android_datepicker_control.htm 这是使用日期选择器的标准方式，我有一种感觉，这就是您需要的。
so i want a time and a date picker to pop up when i click on a button look google Calendar does when you press the fab button on the bottom right. There will be a new window which shows up a date and a time and when you click one of them a picker opens.
Im not sure if i need to create a fragment with a time picker in it and just make the size smaller or if i have to create one via code.
This is my code:
public class NewEventActivity extends AppCompatActivity {
private LayoutInflater inflater;
private String[] arraySpinner;
private Button date_from;
private Button date_to;
private Button time_from;
private Button time_to;
private EditText title;
private EditText invite;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.new_event_fragment);
findviewbyids();
initPickers();
}
public void findviewbyids(){
date_from = (Button) findViewById(R.id.bt_date_from);
time_from = (Button) findViewById(R.id.bt_time_from);
date_to = (Button) findViewById(R.id.bt_date_to);
time_to = (Button) findViewById(R.id.bt_time_to);
title = (EditText) findViewById(R.id.et_title);
invite = (EditText) findViewById(R.id.et_invite);
}
public void initPickers(){
Date today = new Date();
DateFormat df = new SimpleDateFormat("MM/dd/yyyy");
DateFormat tf = new SimpleDateFormat("HH:mm:ss");
String reportDate = df.format(today);
String reportTime = tf.format(today);
date_from.setText(reportDate);
time_from.setText(reportTime);
date_to.setText(reportDate);
time_to.setText(reportTime);
date_from.setVisibility(View.VISIBLE);
date_to.setVisibility(View.VISIBLE);
time_from.setVisibility(View.VISIBLE);
time_to.setVisibility(View.VISIBLE);
date_from.setBackgroundColor(Color.TRANSPARENT);
date_to.setBackgroundColor(Color.TRANSPARENT);
time_from.setBackgroundColor(Color.TRANSPARENT);
time_to.setBackgroundColor(Color.TRANSPARENT);
Spinner group = (Spinner) findViewById(R.id.sp_group);
this.arraySpinner = new String[] {
"1", "2", "3", "4", "5"
};
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
android.R.layout.simple_spinner_item, arraySpinner);
group.setAdapter(adapter);
date_from.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
}
});
}
}
now when i click on the date_from button a datePicker should appear and after setting the date it should overwrite the text on date_from
i hope you get what i mean
Update:
ok i solved it like this:
@Override
protected Dialog onCreateDialog(int id) {
// TODO Auto-generated method stub
if (id == 999) {
df.format(today);
month = today.getMonth();
year = today.getYear();
day = today.getDay();
DatePickerDialog dlg = new DatePickerDialog(this, myDateListener, year, month, day);
return dlg;
}
return null;
}
private DatePickerDialog.OnDateSetListener myDateListener = new DatePickerDialog.OnDateSetListener() {
@Override
public void onDateSet(DatePicker arg0, int arg1, int arg2, int arg3) {
year = arg1;
month = arg2;
day = arg3;
Date date = new Date(year,month,day);
df.format(date);
reportDate = df.format(date);
date_from.setText(reportDate);
}
};
now i got this problems: somehow when the dialog pops up it tells me its the year 116 and that we have Friday the 3rd.
when i select a date then for example 6.10.2016 my Button shows up 3800/00/06
so that means it only gets the correct day.
but why?
Something like this http://www.tutorialspoint.com/android/android_datepicker_control.htm ?? This is standard way to use date picker, I have a feeling that that's what you need.
