Instructions: Create an application that uses a custom adapter. Your application will allow a user to

select a color from a Spinner and once selected, set the background of the activitys layout to the

selected color.

1. Create a custom adapter called ColorAdapter that extends BaseAdapter that will present to

the user a set of color options. The views generated by the custom adapter should be simple

TextViews, where the text value is the name of the color. The background of the text view

should behave as follows:

i. When the spinner is in drop-down mode (i.e. the user clicked the drop-down button and the

various selection options are being displayed), each textviews background color should be the

same as its displayed text value.

ii. When an item is selected, the views background color should be set to white.

2. When the user selects a color from the Spinner, the activitys layout background should be set

to the selected color. One way to change the background color of the layout, which you will

recall is also a view object, is to assign it an ID as you would any regular view object. Then

from within your code you can access the layout by passing its ID to

findViewById(R.id.layout_id), and from there change its background color.

3. Your list of colors should be a predetermined (no fewer than 10 colors) array of strings. For

simplicity, choose colors from Androids Color class (e.g. Color.RED). This will make setting

the background colors of views and layouts easier, since you only need to call the views

setBackgroudColor method with the color parameter. e.g.:

myLayout.setBackgroudColor(Color.parseColor(chosenColor))

// Color.parseColor(String) will only work for a predefined set of color names

// see

https://developer.android.com/reference/android/graphics/Color.html#parseColor(java.la

ng.String)

4. When your application first starts, no color should be selected (the layouts background should

not be changed)

5. Push your project to GitHub.
