Trying to set text of EditText from DatePicker DialogFragment

Question

I am simply trying to get the date from a datepicker dialog I created from one of the many android datepicker tutorials I found online. I seem to be going wrong somewhere in

Answer 1

You need to use an interface to get the data from the datepicker to the caller fragment:

public interface DateListener {
    void passDate(String date);
}

Create a member variable called mListener:

private DateListener mListener;

Override the onAttach & onDetach fragment methods:

@Override
public void onAttach(Activity activity) {
    super.onAttach(activity);
    try {
        mListener = (DateListener) activity;
    } catch (ClassCastException e) {
        throw new ClassCastException(activity.toString() + " must implement DateListener");
    }
}

@Override
public void onDetach() {
    super.onDetach();
    mListener = null;
}

Next, implement this interface in the caller fragment and override the passDate method:

@Override
public void passDate(String date) {
    // Do something with 'date', yourEditText.setText(date) for the example
}

And you should be good to go.
