Color
The Color class has many predefined color constants and allows you to create your own color objects.
Example:
<TextView
android:id="@+id/swimmernameid"
android:background="#ff99ff"
android:text="Doe, Susan"
android:textStyle="bold"
android:textSize="20sp"
android:singleLine="true"
/>
// You can declare a reference variable to the TextView in code.
private TextView swimmerNameView;
// You can get a reference to it by calling findViewById.
// You usually do this in the onCreate method.
swimmerNameView = (TextView) findViewById(R.id.swimmernameid);
swimmerNameView.setTextColor(Color.Black);
swimmerNameView.setText("Swimmer Name");
int color = 0x30FF9966;
swimmerNameView.setBackgroundColor(color);
Color myColor = new Color(red, green, blue);
Where red is an integer between 0 and 255
Where green is an integer between 0 and 255
Where blue is an integer between 0 and 255
