ScrollBarPanelWithClock
Path 2.0 like scrollbar with clock widget for Android.
This is an open source library which uses the scroll bar library. I have added a Clock widget inside the scroll bar panel which gives a Path 2.0 like effect and can be customised according to your needs. Please see the screenshots below to get a better idea.

Usage
Check the attached demo sample app.
Layout
The ExtendedListView replaces a standard ListView widget and provides the ScrollBarPanel capability.
<com.learnNcode.android.ExtendedListView
xmlns:clock="http://schemas.android.com/apk/res-auto"
android:id="@android:id/list"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:choiceMode="singleChoice"
clock:hand_second="@drawable/ic_timer_clock_minute_hand"
clock:scrollBarPanel="@layout/scrollbarpanel"
clock:scrollBarPanelInAnimation="@anim/in"
clock:scrollBarPanelOutAnimation="@anim/out" />You can use/edit the clock widget the following way, this should be done in the layout for scrollbar panel:
<com.learnNcode.android.Clock
xmlns:clock="http://schemas.android.com/apk/res-auto"
android:id="@+id/analogClockScroller"
android:layout_width="25dp"
android:layout_height="25dp"
clock:hand_second="@drawable/ic_timer_clock_minute_hand"
clock:hand_minute="@drawable/ic_timer_clock_minute_hand"
clock:hand_hour="@drawable/ic_timer_clock_hour_hand"
clock:hand_dial="@drawable/ic_timer_clock_dialer"/>Activity
Set your scrollBarPanel
ExtendedListView mListView = (ExtendedListView) findViewById(android.R.id.list);You can attach a position changed listener on the listview and write your desired implementation.
mListView.setOnPositionChangedListener(new OnPositionChangedListener() {
@Override
public void onPositionChanged(ExtendedListView listView, int firstVisiblePosition, View scrollBarPanel) {
Clock analogClockInstance = (Clock) scrollBarPanel.findViewById(R.id.analogClockScroller);
Time time = new Time();
analogClockInstance.setSecondHandVisibility(true); // to visible second hand
time.set(position+3, position, 5, 0, 0, 0);
analogClockInstance.onTimeChanged(time);
}
}You can also directly implement the OnPositionChangedListener, and write your implementation in the overridden method.
public class MainActivity extends Activity implements OnPositionChangedListener {
@Override
public void onPositionChanged(ExtendedListView listView, int position, View scrollBarPanel) {
Clock analogClockInstance = (Clock) scrollBarPanel.findViewById(R.id.analogClockScroller);
Time time = new Time();
analogClockInstance.setSecondHandVisibility(true);
time.set(position+3, position, 5, 0, 0, 0);
analogClockInstance.onTimeChanged(time);
}
}This is how you initialize the clock widget, this should be done inside the OnPositionChanged().
Time timeObj = new Time();
analogClockObj.setSecondHandVisibility(true);
analogClockObj.setVisibility(View.VISIBLE);
timeObj.set(position+3, position, 5, 0, 0, 0); //pass respective values to the clock here.
analogClockObj.onTimeChanged(timeObj);NOTE :
1] You can set visibility for the seconds hand by using setSecondHandVisibility method. Example: analogClockObj.setSecondHandVisibility(true); // To show second hand
2] You can set visibility for the clock widget by using setVisibility method. Example: analogClockObj.setVisibility(View.VISIBLE);
