Clear button.
Hi,
Is it possible to add a third button (clear) to date picker dialog?
Thank you
What would you like to be cleared exactly? There is always a selection in the datepicker.
If you need to clear an alarm in your app, try adding it to your app UI with a seperate button, or a swipe to dismiss action
Hi, thank you for your reply. I have a clickable text field, when user clicks on it date picker dialog shows up. Then user selects a date and date value sets to that textview. The problem is that I don't have a lot of space in that textview and clear button looks terrible there. Is there a way to add an extra button to datepicker dialog such as "Clear"?
Check PR #156 I currently don't really plan to add this functionality, the goal is to stick to the guidelines, but I can always be convinced by compelling arguments.
FWIW, here is a way that you can add a "Clear" button (or any other button for that matter) into DatePickerDialog using version 2.2.0 of MaterialDateTimePicker.
ClearableDatePickerDialog.java:
public class ClearableDatePickerDialog extends DatePickerDialog {
private OnDateClearedListener mOnDateClearedListener;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle state) {
View view = super.onCreateView(inflater, container, state);
LinearLayout buttonContainer = (LinearLayout) view.findViewById(
com.wdullaer.materialdatetimepicker.R.id.done_background);
View clearButton = inflater.inflate(R.layout.date_picker_dialog_clear_button,
buttonContainer, false);
clearButton.setOnClickListener(new ClearClickListener());
buttonContainer.addView(clearButton, 0);
return view;
}
public void setOnDateClearedListener(OnDateClearedListener listener) {
mOnDateClearedListener = listener;
}
public OnDateClearedListener getOnDateClearedListener() {
return mOnDateClearedListener;
}
public interface OnDateClearedListener {
/**
* @param view The view associated with this listener.
*/
void onDateCleared(ClearableDatePickerDialog view);
}
private class ClearClickListener implements View.OnClickListener {
@Override
public void onClick(View view) {
tryVibrate();
OnDateClearedListener listener = getOnDateClearedListener();
if (listener != null) {
listener.onDateCleared(ClearableDatePickerDialog.this);
}
dismiss();
}
}
}

Great stuff. I'll turn that in a gist and add it to the FAQ of the project.
It shows how you can extend this without me having to support a thousand different rarely used options :-)
Is there any possiblity to remove all button..... just by clicking on date...Date will be set to your textview. please send me the code 4 that . Thanx in Advance....!!!!
The pickers extend DialogFragment, so you can create your own Dialog and use them as the content for that.
When not creating their own Dialog, the pickers do not render the OK and Cancel buttons, so this should allow you to create a buttonless dialog.
in datepickerdialog show me this type error java.lang.RuntimeException: Font asset not found fonts/Roboto-Medium.ttf sometime please give me solution how to fix that?
Can you please create a new issue, rather than commenting in totally unrelated ones? I will also need more info on this: at least a stacktrace, the library version and the api version of the device on which the error occurred.
