Focus color is not apply for button in Android-CodePudding

I am trying to set the button background programmatically. But focused color is not applying.

private void drawKeyBackground() {
        String normalColor = "e11515ff";
        String focusedColor = "dd3f3fff";
        Drawable npd = getSelectorDrawable(normalColor,focusedColor);
        Button button = findViewById(R.id.btn1);
        button.setBackground(npd);
    }



public StateListDrawable getSelectorDrawable(String normalColor, String focusedColor) {
        StateListDrawable out = new StateListDrawable();
        out.addState(new int[]{}, getRoundRect(normalColor));
        out.addState(new int[]{ android.R.attr.state_focused}, getRoundRect(focusedColor));
        return out;
    }

public Drawable getRoundRect(String color) {
        RoundRectShape rectShape = new RoundRectShape(new float[]{
                0, 0, 0, 0,
                0, 0, 0, 0
        }, null, null);


        int[] backRGB = new int[3];
        backRGB[0] = Integer.parseInt(color.substring(0,
                2), 16);
        backRGB[1] = Integer.parseInt(color.substring(2,
                4), 16);
        backRGB[2] = Integer.parseInt(color.substring(4),
                16);
        ShapeDrawable shapeDrawable = new ShapeDrawable(rectShape);
        shapeDrawable.getPaint().setColor(Color.rgb(backRGB[0], backRGB[1], backRGB[2]));
        //        shapeDrawable.getPaint().setColor((Styles.getARGBValue(color, Styles.getAlphaValue("sStyleID"))));
        shapeDrawable.getPaint().setStyle(Paint.Style.FILL);
        shapeDrawable.getPaint().setAntiAlias(true);
        shapeDrawable.getPaint().setFlags(Paint.ANTI_ALIAS_FLAG);
        return shapeDrawable;
    }

Please let me some ideas to resolve this issue. How to set the background for view in android.

Change your parent theme in themes.xml to Theme.AppCompat.Light.NoActionBar or another theme parent.

Here is an example for your problem. You may want to play with it a little bit.

Button button = findViewById(R.id.button);
        
GradientDrawable pressed = new GradientDrawable();
pressed.setShape(GradientDrawable.RECTANGLE);
pressed.setGradientType(GradientDrawable.LINEAR_GRADIENT);
pressed.setColor(Color.WHITE);
pressed.setStroke(10, Color.GREEN);
pressed.setCornerRadius(30F);
        
GradientDrawable focused = new GradientDrawable();
focused.setShape(GradientDrawable.RECTANGLE);
focused.setGradientType(GradientDrawable.LINEAR_GRADIENT);
focused.setColor(Color.WHITE);
focused.setStroke(10, Color.RED);
focused.setCornerRadius(30F);

GradientDrawable enabled = new GradientDrawable();
enabled.setShape(GradientDrawable.RECTANGLE);
enabled.setGradientType(GradientDrawable.LINEAR_GRADIENT);
enabled.setColor(Color.WHITE);
enabled.setStroke(10, Color.BLUE);
enabled.setCornerRadius(30F);
        
StateListDrawable drawables = new StateListDrawable();
drawables.addState(new int[] { android.R.attr.state_pressed }, pressed);
drawables.addState(new int[] { android.R.attr.state_focused }, focused);
drawables.addState(new int[] { android.R.attr.state_enabled }, enabled);
        
button.setBackground(drawables);
//You might not even need this one.
//button.setFocusableInTouchMode(true);
