How to create a Drawable with needed background color programmatically?

Question

I need to create a simple Drawable object with needed color as background color, but I don't know how I can do it programmatically without using a XML schema (is it possible really?). Please, tell me, I need it to do for making a LayerDrawable and working with SeekBar (changing background of SeekBar programmatically). Thank you in advance.

You should try using a ColorDrawable. It can be constructed with a color using the constructor ColorDrawable(int color)

Thank you. But please, tell me, how can I set Id for Drawable? I need to set "android:id/background" for a new drawable

I don't understand what you are trying to do. What do you need the id for? You can just add the ColorDrawable to your LayerDrawable using the constructor LayerDrawable(Drawable[] layers). You don't need any id for the ColorDrawable. The id of the layer can then be set with LayerDrawable.setId (int index, int id)

As it is suggested by @Thrakbad, you can use ColorDrawable:

    TextView textView = new TextView(this);
    ColorDrawable colorDrawable = new ColorDrawable(0xFFFF0000);
    textView.setBackgroundDrawable(colorDrawable);

ColorDrawable will be helpful you in your case, you can pass parameter color for your drawable.

or you can do something like below:

ImageView imgStatus = (ImageView) findViewById(R.id.imgInfoIcon);
// Load the icon as drawable object
Drawable d = getResources().getDrawable(R.drawable.ic_menu_info_details);

// Get the color of the icon depending on system state
int iconColor = android.graphics.Color.BLACK
if (systemState == Status.ERROR)
    iconColor = android.graphics.Color.RED
else if (systemState == Status.WARNING)
    iconColor = android.graphics.Color.YELLOW
else if (systemState == Status.OK)
    iconColor = android.graphics.Color.GREEN

// Set the correct new color
d.setColorFilter( iconColor, Mode.MULTIPLY );

// Load the updated drawable to the image viewer
imgStatus.setImageDrawable(d);

above code is originally posted here

this way you can't at run time, its better to create function pass your view id, and set appropriate color to your view.
