The missing DrawableToolbox for Android. Create drawables programmatically and get rid of the boring and always repeated drawable.xml files.

Features

• Create drawables programmatically
• Support <shape>, <rotate>, <scale>, <ripple>, <layer-list> drawables
• Support 'flip' (vertical or horizontal)

Contribute

• Please file an issue or pull request

Gradle

dependencies {
    implementation 'com.github.duanhong169:drawabletoolbox:${latestVersion}'
    ...
}

Replace ${latestVersion} with the latest version code. See releases.

Usage

Use the DrawableBuilder to setup the Drawable and call build() to create it.

Please check all the supported APIs in DrawableBuilder.kt.

Here are some examples:

Code:

DrawableBuilder()
        .rectangle()
        .hairlineBordered()
        .strokeColor(COLOR_DEFAULT)
        .strokeColorPressed(COLOR_PRESSED)
        .ripple()
        .build()

Result:

Code:

DrawableBuilder()
        .rectangle()
        .hairlineBordered()
        .mediumDashed()
        .strokeColor(COLOR_DEFAULT)
        .strokeColorPressed(COLOR_PRESSED)
        .ripple()
        .build()

Result:

Code:

DrawableBuilder()
        .rectangle()
        .rounded()
        .solidColor(COLOR_DEFAULT)
        .solidColorPressed(COLOR_PRESSED)
        .build()

Result:

Code:

DrawableBuilder()
        .rectangle()
        .hairlineBordered()
        .longDashed()
        .rounded()
        .strokeColor(COLOR_DEFAULT)
        .strokeColorPressed(COLOR_PRESSED)
        .ripple()
        .build()

Result:

Code:

DrawableBuilder()
        .rectangle()
        .rounded()
        .gradient()
        .linearGradient()
        .angle(90)
        .startColor(COLOR_DEFAULT)
        .endColor(ContextCompat.getColor(context, R.color.colorPrimaryDark))
        .ripple()
        .rippleColor(COLOR_PRESSED)
        .build()

Result:

Code:

val baseBuilder = DrawableBuilder()
        .rectangle()
        .rounded()
        .gradient()
        .gradientType(GradientDrawable.LINEAR_GRADIENT)
        .angle(90)
val normalState = baseBuilder
        .startColor(COLOR_DEFAULT)
        .endColor(ContextCompat.getColor(context, R.color.colorPrimaryDark))
        .build()
val pressedState = baseBuilder
        .startColor(COLOR_PRESSED)
        .endColor(ContextCompat.getColor(context, R.color.colorAccentDark))
        .build()

StateListDrawableBuilder()
        .normal(normalState)
        .pressed(pressedState)
        .build()

Result:

Code:

val baseBuilder = DrawableBuilder()
        .rectangle()
        .rounded()
        .hairlineBordered()
        .strokeColor(COLOR_DEFAULT)
        .solidColorSelected(COLOR_DEFAULT)
        .ripple()

return when(type) {
    SegmentedControlDrawableSpec.TYPE_LEFT_MOST -> {
        baseBuilder.topRightRadius(0)
                .bottomRightRadius(0)
                .build()
    }
    SegmentedControlDrawableSpec.TYPE_RIGHT_MOST -> {
        baseBuilder.topLeftRadius(0)
                .bottomLeftRadius(0)
                .build()
    }
    else -> {
        baseBuilder.cornerRadius(0).build()
    }
}

Result:

Code:

val layer1 = DrawableBuilder()
        .size(200)
        .rectangle()
        .rounded()
        .hairlineBordered()
