This is a simple android library to make a circular menu UI. Just specify a couple of params and it's ready to use!
First download the jar and add it to your project. The exact location to include the jar will depend on your specific IDE. You can also add wheel-menu-library as a library project and reference it directly without adding the jar.
Import the package com.anupcowkur.wheelmenu into the activity in which you want to include the menu.
Initialize the menu with the constructor in the format:
new WheelMenu(Context, no_of_divisions_in_your_menu,
drawable_to_use_as_wheel_img,
imageview_for_the_wheel,
snap_to_center_flag);
ex: A menu with 12 divisions
Initialize the menu:
WheelMenu wm = new WheelMenu(MainActivity.this,
12, R.drawable.wheel,
wheel_image, true);
wheel_image is the id of the image view
ImageView wheel_image = (ImageView) findViewById(R.id.wheel);
and in the xml file:
<ImageView
android:src="@drawable/wheel"
android:id="@+id/wheel"
android:scaleType="matrix"
android:layout_height="300dp"
android:layout_width="300dp"></ImageView>
That's it!
Now, to get the currently selected position simply call
wm.getSelected();
This will return values in the range 1....no_of_divisions_in_your_menu
In our example, it will return values from 1 to 12 depending on the user's selection.
####snap-to-center
This flag is set to true by default. If true, crossing into a division will cause the wheel to auto-align itself to the center of the division. Otherwise, the wheel will just hang around wherever the user left it.
Check out the sample application to see it in action!
