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);
