This library can help you easily layout and draw dividers on existing views. For better performance, don't create new views for drawing dividers anymore, use drawable instead.

Install

repositories {
    maven { url "https://jitpack.io" }
}
dependencies {
    compile 'com.github.nekocode:DividerDrawable:{lastest-version}'
}

Usage

Obtain a new DividerDrawable instance. And you can set the color and stroke witdh of the divider.

final DividerDrawable dividerDrawable = new DividerDrawable();
dividerDrawable.setStrokeWidth(10)
        .setColor(0xFFFFFFFF)

Similar to the view layout, the DividerDrawable also has a layout that can help draw divider to the relative position of the container(view/drawable/canvas).

dividerDrawable.getLayout()
        .setOrientation(DividerLayout.ORIENTATION_VERTICAL)
        .setAlign(DividerLayout.ALIGN_PARENT_BOTTOM)
        .setCenter(DividerLayout.CENTER_HORIZONTAL)
        .setMarginBottomDp(20);

You can use DividerUtils to easily combine the divider drawable to your existing backgroud drawable.

DividerUtils.addDividersTo(textView, dividerDrawable);

If you changed the divider's layout params, don't forget to notify the changes.

dividerDrawable.notifyLayoutChanged();
