# Wheel widget for Android # To include the wheel widget in the current layout, you should add in the layout xml this lines: <it.sephiroth.android.wheel.view.Wheel android:id="@+id/wheel" xmlns:sephiroth="http://schemas.android.com/apk/res-auto" android:layout_width="match_parent" android:layout_height="match_parent" sephiroth:numRotations="6" sephiroth:ticks="28" /> Where **numRotations** is the max number of rotations the wheel can perform and **ticks** is the total number of ticks the wheel will display. In your activity you can add a **OnScrollListener** listener to the wheel widget, in this way: mWheel = (Wheel) findViewById( R.id.wheel ); mWheel.setOnScrollListener( new OnScrollListener() { @Override public void onScrollStarted( Wheel view, float value, int roundValue ) { } @Override public void onScrollFinished( Wheel view, float value, int roundValue ) { } @Override public void onScroll( Wheel view, float value, int roundValue ) { } } ); Where **float value** is a value between -1.0 and 1.0 of the current indicator position and **int roundValue** is a value between -(ticks*numRotations) and (ticks*numRotations) ###Change the Wheel value The wheel position and value chan be changed programmatically at runtime using the Wheel's method **setValue**: public void setValue( float value, boolean fireScrollEvent ); - value is the new wheel value, a float between -1.0f and 1.0f, where 0.0f it's the center of the wheel. - fireScrollEvent: if true, once this method is called the onScrollFinished method will be called. ## Screen Shots ##
