    <p>I am trying to create a custom date picker button component. The button displays the date and when clicked it opens the date picker dialog box. I have implemented this method using the Android Dev Docs/Tutorial however I have 2 of them in my code and I figured it would be better to create a custom class called DateButton which would clean up my code a bit. So whenever I need a similar button I can create a declare a DateButton in my XML. Anyways this is my first time creating a custom view and I need some help whenever I try to add my custom button to my layout I get an error: </p> <pre><code>error! ClassNotFoundException: android.app.DatePickerDialog$OnDateSetListener </code></pre> <p>Here is what I want the button to look at (very simple)</p> <p><img src="https://i.stack.imgur.com/EtfHJ.png" alt="enter image description here"></p> <p>and when it is clicked it will pop up the built in android datepicker dialog:</p> <p><img src="https://i.stack.imgur.com/dupHR.png" alt="enter image description here"></p> <p>Here is my current code for this custom datebutton:</p> <pre><code>import android.app.DatePickerDialog; import android.app.DatePickerDialog.OnDateSetListener; import android.content.Context; import android.util.AttributeSet; import android.view.View; import android.view.View.OnClickListener; import android.widget.Button; import android.widget.DatePicker; public class DateButton extends Button implements OnClickListener, OnDateSetListener { private static final int DATE_DIALOG_ID = 0; private int mYear; private int mMonth; private int mDay; private OnDateSetListener mDateSetListener; public DateButton(Context context) { super(context); } public DateButton(Context arg0, AttributeSet arg1) { super(arg0, arg1); } public DateButton(Context arg0, AttributeSet arg1, int arg2) { super(arg0, arg1, arg2); } @Override public void onClick(View v) { showDialog(DATE_DIALOG_ID); } private DatePickerDialog showDialog(int dateDialogId) { return new DatePickerDialog(getContext(), mDateSetListener, mYear, mMonth, mDay); } public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) { mYear = year; mMonth = monthOfYear; mDay = dayOfMonth; updateDisplay(); } private void updateDisplay() { this.setText( new StringBuilder() // Month is 0 based so add 1 .append(pad(mMonth + 1)).append("/") .append(pad(mDay)).append("/") .append(mYear).append(" ")); } //if single digit append "0" to the number private static String pad(int c) { if (c &gt;= 10) return String.valueOf(c); else return "0" + String.valueOf(c); } } </code></pre> <p>EDIT: I'm still running into trouble anyone have any examples of something similar to this? Thanks for any help!</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
