Using a gradientDrawable with more than three colors set

Question

According to what I\'ve read, you can use a gradientDrawable and have three colors set for it, for example:

Answer 1

I think the below are possible solutions.

• You can create multiple shapes with gradients and form a bigger shape.

• You can create your own GradientDrawable by extending the GradientDrawable Class refer to the below doc.

• Gradient Drawable Documentation

Answer 2

put this code in your onCreate() method:

ShapeDrawable.ShaderFactory shaderFactory = new ShapeDrawable.ShaderFactory() {
    @Override
    public Shader resize(int width, int height) {
        LinearGradient linearGradient = new LinearGradient(0, 0, width, height,
            new int[] { 
                0xFF1e5799, 
                0xFF207cca, 
                0xFF2989d8, 
                0xFF207cca }, //substitute the correct colors for these
            new float[] {
                0, 0.40f, 0.60f, 1 },
            Shader.TileMode.REPEAT);
         return linearGradient;
    }
};
PaintDrawable paint = new PaintDrawable();
paint.setShape(new RectShape());
paint.setShaderFactory(shaderFactory);

and use this drawable as a background.

You can add more than three colors in xml also by creating layers. But in XML it is quite complicated.

Answer 3

It is not possible to do into a xml file, but you can apply +3 color gradient in yout java code with GradientDrawable class:

GradientDrawable gradientDrawable = new GradientDrawable(
                Orientation.TOP_BOTTOM,
                new int[]{ContextCompat.getColor(this, R.color.color1),
                        ContextCompat.getColor(this, R.color.color2),
                        ContextCompat.getColor(this, R.color.color3),
                        ContextCompat.getColor(this, R.color.color4)});

        findViewById(R.id.background).setBackground(gradientDrawable);

Answer 4

In Kotlin you can do it like this:

replace color1,2,..n with your color values

                 //Create Gradient 
                val gradientDrawable = GradientDrawable(
                    GradientDrawable.Orientation.TOP_BOTTOM,
                    intArrayOf(color1,color1 ,color1, colorn)
                );
                gradientDrawable.cornerRadius = 0f;

Answer 5

Using GradientDrawble we can achieve this

GradientDrawable gradientInsta = new GradientDrawable(GradientDrawable.Orientation.LEFT_RIGHT,
                new int[] {
                        Color.parseColor("#F9ED32"),
                        Color.parseColor("#F6C83F"),
                        Color.parseColor("#F2735F"), 
                        Color.parseColor("#EF3E73"),
                        Color.parseColor("#EE2A7B"),
                        Color.parseColor("#D22A8A"),
                        Color.parseColor("#8B2AB1"),
                        Color.parseColor("#1C2AEF"),
                        Color.parseColor("#002AFF”),
                        ContextCompat.getColor(MainActivity.this, R.color.colorPrimary)
        });
findViewById(R.id.insta).setBackground(gradientInsta);
