androidwheel's Introduction

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 -(ticksnumRotations) and (ticksnumRotations)

###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.

androidwheel's Issues

setValue can not work

mWheel.setValue(1, false) seems not work in onCreate , but in OnScrollListener it works fine.

Error importing android wheel to my project

Hey there! I just imported this project to Eclipse to use it as library, but when I added this library to my project, a lot of errors appeared suddenly in my project... Errors were like this: R cannot be resolved to a variable. So, which is the correct way to import android wheel?

Numbers

Is there any way to put numbers to wheel instead vertical lines?

Set wheel position from code

Thank you for making this very useful widget. I need to set its starting position to something other than halfway - e.g. the total range is 0 to 100, but I want it to start at 30 rather than 50.

How can this be done?

can not run

there is no main class it.sephiroth.test.test.MainActivity

SetValue causes a "divide by 0" exception.

Using the setvalue method gives me a divide by zero exception.

My code is as follows:

            mWheel = (Wheel) v.findViewById(R.id.wheel);
            mWheel.setOnScrollListener( new Wheel.OnScrollListener() {

                @Override
                public void onScrollStarted( Wheel view, float value, int roundValue ) {
                    Log.i("SPINZ", "STARTED: f: " + value + " / i: " + roundValue);
                }

                @Override
                public void onScrollFinished( Wheel view, float value, int roundValue ) {
                    Log.i("SPINZ", "FINISHED: f: " + value + " / i: " + roundValue);
                    roundValue *= -1;
                    roundValue += 40;
                    if (roundValue >= 0 && roundValue < sections.length)
                        mSectionTV.setText(sections[roundValue]);
                }

                @Override
                public void onScroll( Wheel view, float value, int roundValue ) {

                    roundValue *= -1;
                    roundValue += 40;
                    if (roundValue >= 0 && roundValue < sections.length)
                        mSectionTV.setText(sections[roundValue]);
                }
            } );

            mWheel.setValue(1.0f, true);

If I take mWheel.setValue(1.0f, true) and move it to right after mWheel = (Wheel) v.findViewById(R.id.wheel), then I don't get the divide by zero exception, but the method doesn't do anything either.

Adding support for Android 2.1 and 2.2

Your wheel looks great & funny.
But, I must set API to >= 9 when build because in Wheel.java line 1084 you define a OverScroller (which only from API 9+). This mean I cannot run this app on Android 2.1 and 2.2.

Can you take time to add support for 2.1 and 2.2?

Thanks.

Use with minimal XML

Specifically, I'm trying to move the lines

sephiroth:numRotations="2"
sephiroth:ticks="20"

to code, so that I can externalize the wheel and change it at will in my app. However, I can't find a way to control these via java rather than xml.

Sample

Do you have any samples??
