I have a horizontal line created with a view like this:
<View
android:layout_width="fill_parent"
android:id="@+id/led_connection"
android:layout_height="5dip"
android:background="#fff"
android:layout_marginBottom="15dp" />
I want to know how can I change the color programatically. Because I am trying to use setBackground and setBackgroundDrawable but SDK sais me that it cannot applied to a View.
I'm getting the view with this:
View led_connection = (View)v.findViewById(R.id.led_connection);

If you have html colors, can try this to solve your problem.
led_connection.setBackgroundColor(Color.parseColor("#679456"));
led_connection.setBackgroundColor(Color.parseColor("html_code_colors"));
As Marcin Orlowski sais, the solution is use setBackgroundColor with an hex color with the 2 first digits that are alpha level.
I'm using for GREEN:
led_connection.setBackgroundColor(0xFF008000); // GREEN
and for RED:
led_connection.setBackgroundColor(0xFFFF0000); // RED
Thank you
