How to change colors of a Drawable in Android?

I'm working on an android application, and I have a drawable that I'm loading up from a source image. On this image, I'd like to convert all of the white pixels to a different color, say blue, and then cache the resultant Drawable object so I can use it later.

So for example say I have a 20x20 PNG file that has a white circle in the middle, and that everything outside the circle is transparent. What's the best way to turn that white circle blue and cache the results? Does the answer change if I want to use that source image to create several new Drawables (say blue, red, green, orange, etc)?

I'm guessing that I'll want to use a ColorMatrix in some way, but I'm not sure how.

I think you can actually just use Drawable.setColorFilter( 0xffff0000, Mode.MULTIPLY ). This would set white pixels to red but I don't think it would affect the transparent pixels.

See Drawable#setColorFilter

Give this code a try:

ImageView lineColorCode = (ImageView)convertView.findViewById(R.id.line_color_code);
int color = Color.parseColor("#AE6118"); //The color u want 			
lineColorCode.setColorFilter(color);

I know this question was ask way before Lollipop but I would like to add a nice way to do this on Android 5.+. You make an xml drawable that references the original one and set tint on it like such:

<?xml version="1.0" encoding="utf-8"?>
<bitmap
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:src="@drawable/ic_back"
    android:tint="@color/red_tint"/>

The new support v4 bring tint back to api 4.

you can do it like this

public static Drawable setTint(Drawable d, int color) {
    Drawable wrappedDrawable = DrawableCompat.wrap(d);
    DrawableCompat.setTint(wrappedDrawable, color);
    return wrappedDrawable;
}

If you have a drawable that's a solid color and you want to change it to a differnet solid color, you can use a ColorMatrixColorFilter. Transparency is preserved.

int iColor = Color.parseColor(color);

int red   = (iColor & 0xFF0000) / 0xFFFF;
int green = (iColor & 0xFF00) / 0xFF;
int blue  = iColor & 0xFF;
		
float[] matrix = { 0, 0, 0, 0, red,
				   0, 0, 0, 0, green,
				   0, 0, 0, 0, blue,
				   0, 0, 0, 1, 0 };
		
ColorFilter colorFilter = new ColorMatrixColorFilter(matrix);
drawable.setColorFilter(colorFilter);

I also use ImageView for icons (in ListView or settings screen). But I think there is much simpler way to do that.

Use tint to change the color overlay on your selected icon.

In xml,

android:tint="@color/accent"
android:src="@drawable/ic_event" 

works fine since it comes from AppCompat

You should do this for all APIs:

Drawable myIcon = getResources().getDrawable( R.drawable.button ); 
ColorFilter filter = new LightingColorFilter( Color.BLACK, Color.BLACK);
myIcon.setColorFilter(filter);

I was able to do this with the following code, which is taken from an activity (the layout is a very simple one, just containing an ImageView, and is not posted here).

private static final int[] FROM_COLOR = new int[]{49, 179, 110};
private static final int THRESHOLD = 3;

public void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.test_colors);

    ImageView iv = (ImageView) findViewById(R.id.img);
    Drawable d = getResources().getDrawable(RES);
    iv.setImageDrawable(adjust(d));
}

private Drawable adjust(Drawable d)
{
    int to = Color.RED;

    //Need to copy to ensure that the bitmap is mutable.
    Bitmap src = ((BitmapDrawable) d).getBitmap();
    Bitmap bitmap = src.copy(Bitmap.Config.ARGB_8888, true);
    for(int x = 0;x < bitmap.getWidth();x++)
        for(int y = 0;y < bitmap.getHeight();y++)
            if(match(bitmap.getPixel(x, y))) 
                bitmap.setPixel(x, y, to);
            
    return new BitmapDrawable(bitmap);
}

private boolean match(int pixel)
{
    //There may be a better way to match, but I wanted to do a comparison ignoring
    //transparency, so I couldn't just do a direct integer compare.
    return Math.abs(Color.red(pixel) - FROM_COLOR[0]) < THRESHOLD &&
        Math.abs(Color.green(pixel) - FROM_COLOR[1]) < THRESHOLD &&
        Math.abs(Color.blue(pixel) - FROM_COLOR[2]) < THRESHOLD;
}

You can solve it using Android support compat libraries. :)

 // mutate to not share its state with any other drawable
 Drawable drawableWrap = DrawableCompat.wrap(drawable).mutate();
 DrawableCompat.setTint(drawableWrap, ContextCompat.getColor(getContext(), R.color.your_color))

In your Activity you can tint your PNG image resources with a single colour:

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    myColorTint();
    setContentView(R.layout.activity_main);
}

private void myColorTint() {
    int tint = Color.parseColor("#0000FF"); // R.color.blue;
    PorterDuff.Mode mode = PorterDuff.Mode.SRC_ATOP;
    // add your drawable resources you wish to tint to the drawables array...
    int drawables[] = { R.drawable.ic_action_edit, R.drawable.ic_action_refresh };
    for (int id : drawables) {
        Drawable icon = getResources().getDrawable(id);
        icon.setColorFilter(tint,mode);
    }
}

Now when you use the R.drawable.* it should be coloured with the desired tint. If you need additional colours then you should be able to .mutate() the drawable.

view.getDrawable().mutate().setColorFilter(0xff777777, PorterDuff.Mode.MULTIPLY); 

Thanks to @sabadow

This code snippet worked for me:

PorterDuffColorFilter porterDuffColorFilter = new PorterDuffColorFilter(getResources().getColor(R.color.your_color),PorterDuff.Mode.MULTIPLY);

imgView.getDrawable().setColorFilter(porterDuffColorFilter);
imgView.setBackgroundColor(Color.TRANSPARENT)

If you have your drawable set to the ImageView you can do it with a 1 liner:

yourImageView.setColorFilter(context.getResources().getColor(R.color.YOUR_COLOR_HERE);

Too late but in case someone need it:

   fun setDrawableColor(drawable: Drawable, color: Int) :Drawable {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
            drawable.colorFilter = BlendModeColorFilter(color, BlendMode.SRC_ATOP)
            return drawable
        } else {
            drawable.setColorFilter(color, PorterDuff.Mode.SRC_ATOP)
            return drawable
        }
    }

This works with everything with background:

Textview, Button...

TextView text = (TextView) View.findViewById(R.id.MyText);
text.setBackgroundResource(Icon);    
text.getBackground().setColorFilter(getResources().getColor(Color), PorterDuff.Mode.SRC_ATOP);

There are so many solution but nobody suggested if the color resource xml file already have color then we can pick directly from there also as below:

ImageView imageView = (ImageView) findViewById(R.id.imageview);
imageView.setColorFilter(getString(R.color.your_color));

Short example to change drawable color according to isWorking field.

My shape xml:

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" >
    <solid android:color="@android:color/holo_blue_bright" />
    <corners android:radius="30dp" />
    <size
        android:height="15dp"
        android:width="15dp" />
</shape>

My method to change:

private Drawable getColoredDrawable(int drawableResId, boolean isworking) {
	Drawable d = getResources().getDrawable(R.drawable.shape);
	ColorFilter filter = new LightingColorFilter(
			isworking ? Color.GREEN : Color.RED,
			isworking ? Color.GREEN : Color.RED);
	d.setColorFilter(filter);
	return d;
}

Example of usage:

text1.setCompoundDrawablesWithIntrinsicBounds(getColoredDrawable(R.drawable.shape, isworking()), null, null, null);

Int color = Color.GRAY; 
// or int color = Color.argb(123,255,0,5);
// or int color = 0xaaff000;

in XML /res/values/color.xml

<?xml version="1.0" encoding="utf-8">
<resources>
	<color name="colorRed">#ff0000</color>
</resoures> 

Java Code

int color = ContextCompat.getColor(context, R.color.colorRed);

GradientDrawable drawableBg = yourView.getBackground().mutate();
drawableBg.setColor(color);

It works for some simple drawables. I used it on a simple solid color rect shape with rounded corners and needed to change that color with different layouts.

Try this

android:backgroundTint="#101010"

Try android:backgroundTint="@color/quantum_black_100"

Koltin solution using view binding:

binding.avatar.drawable.colorFilter = BlendModeColorFilterCompat.createBlendModeColorFilterCompat(R.color.white, BlendModeCompat.SRC_ATOP)

This uses the latest version of the core androidx library.

I just encountered the issue and solved it by replacing:

android:tint="@color/yellow_800"

to the following

app:tint="@color/yellow_800"

It's very very simple when you use a library to do that for you. Try this library

You can call like this:

Icon.on(holderView).color(R.color.your_color).icon(R.mipmap.your_icon).put();
