    copied!<p>Hi!</p> <p>I have a custom preference class extending DialogPreference. I need to bind it with my PreferenceFragment class (i got it from here: http://stackoverflow.com/questions/5533078/timepicker-in-preferencescreen). How can it be achieved? Do i need to declare the custom DialogPrefrence in my preferences.xml layout file?</p> <p>Here's the DialogPreference class:</p> <pre><code>public class TimePreference extends DialogPreference { private int lastHour=0; private int lastMinute=0; private TimePicker picker=null; public static int getHour(String time) { String[] pieces=time.split(":"); return(Integer.parseInt(pieces[0])); } public static int getMinute(String time) { String[] pieces=time.split(":"); return(Integer.parseInt(pieces[1])); } public TimePreference(Context ctxt) { this(ctxt, null); } public TimePreference(Context ctxt, AttributeSet attrs) { this(ctxt, attrs, 0); } public TimePreference(Context ctxt, AttributeSet attrs, int defStyle) { super(ctxt, attrs, defStyle); setPositiveButtonText("Set"); setNegativeButtonText("Cancel"); } @Override protected View onCreateDialogView() { picker=new TimePicker(getContext()); return(picker); } @Override protected void onBindDialogView(View v) { super.onBindDialogView(v); picker.setCurrentHour(lastHour); picker.setCurrentMinute(lastMinute); } @Override protected void onDialogClosed(boolean positiveResult) { super.onDialogClosed(positiveResult); if (positiveResult) { lastHour=picker.getCurrentHour(); lastMinute=picker.getCurrentMinute(); String time=String.valueOf(lastHour)+":"+String.valueOf(lastMinute); if (callChangeListener(time)) { persistString(time); } } } @Override protected Object onGetDefaultValue(TypedArray a, int index) { return(a.getString(index)); } @Override protected void onSetInitialValue(boolean restoreValue, Object defaultValue) { String time=null; if (restoreValue) { if (defaultValue==null) { time=getPersistedString("00:00"); } else { time=getPersistedString(defaultValue.toString()); } } else { time=defaultValue.toString(); } lastHour=getHour(time); lastMinute=getMinute(time); } } </code></pre> <p>Thank you very much!</p>
