#DiscreteSeekBar

DiscreteSeekbar is my poor attempt to develop an android implementation of the Discrete Slider component from the Google Material Design Guidelines.

##Prologe I really hope Google provides developers with a better (and official) implementation ;)

##Warning After a bunch of hours trying to replicate the exact feel of the Material's Discrete Seekbar, with a beautiful stuff-that-morphs-into-other-stuff animation I was convinced about releasing the current code.

android.util.Log.wtf("WARNING!! HACKERY-DRAGONS!!");

I've done a few bit of hacky cede and a bunch of things I'm not completely proud of, so use under your sole responsibility (or help me improve it via pull-requests!)

##Implementation details This thing runs on minSDK=7 (well, technically could run 4 but can't test since AVDs for api 4 are deprecated and just don't boot). Obviously some of the subtle animations (navigating with the Keyboard, the Ripple effect, text fade ins/fade outs, etc) are not going to work on APIS lower than 11, but the bubble thing does. And I haven't found a way of improving this with 11-21 APIs, so...

The base SeekBar is pretty simple. Just 3 drawables for the track, progress and thumb. Some touch event logic to drag, some key event logic to move, and that's all.

It supports custom ranges (custom min/max), even for negative values.

The bubble thing DOESN'T USE VectorDrawableMagic . I was not really needed for such a simple morph. It uses instead an Animatable Drawable for the animation with a lot of hackery for callbacks, drawing and a bunch of old simple math.

For this to work (and sync with events, etc) I've written a fair amount of shit questionable code...

The material-floating-thing is composed into the WindowManager (like the typical overflow menus) to be able to show it over other Views without needing to set the SeekBar big enough to account for the (variable) size of he floating thing.

For this I'm not sure about the amounts of things I've copied from PopupWindow and the possible issues.

##Dependencies It uses com.android.support:support-v4 as the only dependency.

##Usage This is published in jCenter so you need to use the appropiate repo:

repositories {

  jcenter() 
}
  dependencies {

  compile 'org.adw.library:discrete-seekbar:1.0.1' 
}

Once imported into your project, you just need to put them into your layous like:

<org.adw.library.widgets.discreteseekbar.DiscreteSeekBar

android:layout_width="match_parent"

android:layout_height="wrap_content"

app:dsb_min="2"

app:dsb_max="15" />

####Parameters You can tweak a few things of the DiscreteSeekbar:

  • dsb_min: minimum value
  • dsb_max: maximum value
  • dsb_value: current value
  • dsb_mirrorForRtl: reverse the DiscreteSeekBar for RTL locales
  • dsb_allowTrackClickToDrag: allows clicking outside the thumb circle to initiate drag. Default TRUE
  • dsb_indicatorFormatter: a string Format to apply to the value inside the bubble indicator.
  • dsb_indicatorPopupEnabled: choose if the bubble indicator will be shown. Default TRUE

####Design

  • dsb_progressColor: color/colorStateList for the progress bar and thumb drawable
  • dsb_trackColor: color/colorStateList for the track drawable
  • dsb_indicatorTextAppearance: TextAppearance for the bubble indicator
  • dsb_indicatorColor: color/colorStateList for the bubble shaped drawable
  • dsb_indicatorElevation: related to android:elevation. Will only be used on API level 21+
  • dsb_rippleColor: color/colorStateList for the ripple drawable seen when pressing the thumb. (Yes, it does a kind of "ripple" on API levels lower than 21 and a real RippleDrawable for 21+.
  • dsb_trackHeight: dimension for the height of the track drawable.
  • dsb_scrubberHeight: dimension for the height of the scrubber (selected area) drawable.
  • dsb_thumbSize: dimension for the size of the thumb drawable.
  • dsb_indicatorSeparation: dimension for the vertical distance from the thumb to the indicator.

You can also use the attribute discreteSeekBarStyle on your themes with a custom Style to be applied to all the DiscreteSeekBars on your app/activity/fragment/whatever.

Resources

Android Unused Resources is a Java application that will scan your project for unused resources. Unused resources needlessly take up space, increase the build time, and clutter the IDE's auto-complete list.

puree-android is a log collector which provides some features like below:

  • Filtering: Enable to interrupt process before sending log. You can add common params to logs, or the sampling of logs.
  • Buffering: Store logs to buffer until log was sent.
  • Batching: Enable to send logs by 1 request.
  • Retrying: Retry to send logs after buckoff time automatically if sending logs fails.

Puree helps you unify your logging infrastructure.

This plugin manages Android SDK and build tools for Gradle.

DEPRECATED

DiscreteSeekbar is an android implementation of the Discrete Slider component from the Google Material Design Guidelines.

android-material-icons allows you to include any of the Material Design icons in your texts, your ActionBar, and even in your EditTexts. Icons are infinitely scalable, and customizable with shadows and everything you can do on texts.

Fit

Framework for dispatching various procedure on update application.
