ProperRatingBar

Inspired by stock android RatingBar. Simpler, has features that original lacks.

What is this about

Whatever you need to display some rating or pricing category - just use ProperRatingBar so this:

<io.techery.properratingbar.ProperRatingBar
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textSize="22sp"
        android:textStyle="bold"
        app:prb_defaultRating="4"
        app:prb_symbolicTick="$"
        app:prb_symbolicTickNormalColor="@android:color/darker_gray"
        app:prb_symbolicTickSelectedColor="@android:color/holo_green_dark"
        app:prb_totalTicks="5"
        />

becomes this:

Example

See video below for possible usage scenarios.

Motivation

Why bother and design our own element?

Well, stock Android RatingBar lacks some styling attributes that you would expect from it and sometimes offers unexpected behavior.

Besides that, we needed to use symbols like '$' as rating bar ticks in our project - none of third-patry libraries out there provides that functionality.

Installation

Library's minSdkVersion is set to 14.

We use jitpack, so you can obtain made-up library right from our github sources in your module's build.gradle file:

compile 'com.github.techery:properratingbar:{version_name}'

Also you need to add jitpack as repository in the same file:

repositories {
        // ...
        maven { url "https://jitpack.io" }
    }

API Reference

So far we only support customising via xml layout. Here is the list of applicable attributes:

• prb_totalTicks: total number of ticks to show. Default is '5'

• prb_defaultRating: use this to set rating from xml. Default is '3'

• prb_clickable: if set to 'true' - use will be able to change rating by clicking. Default is 'false'

• prb_symbolicTick: symbol to be used as a tick. Default is '$'

• android:textSize: text size of symbolic tick. Default is '15sp'

• android:textStyle: text style of symbolic tick. Possible: 'bold', 'italic', 'normal'. Default is 'normal'

• prb_symbolicTickNormalColor: color of symbolic tick that is not selected (not rated). Default is '#FF000000' (black)

• prb_symbolicTickSelectedColor: color of symbolic tick that is selected (rated). Default is '#FF888888' (gray)

• prb_tickNormalDrawable: drawable resource to use as a tick that is not selected (not rated). No default value

• prb_tickSelectedDrawable: drawable resource to use as a tick that is selected (rated). No default value

• prb_tickSpacing: margin to be applied to tick drawables. Only applies to drawable-type ticks. Default is '1dp' (gray)

Also there's a number of methods to operate on ProperRatingBar programmatically:

public boolean isClickable();

/**
 * Nifty sugar method to just toggle clickable to opposite state.
 */
public void toggleClickable();

public void setClickable(boolean clickable);

/**
* Get the attached {@link RatingListener}
* @return listener or null if none was set
*/
@Nullable
public RatingListener getListener();

/**
* Set the {@link RatingListener} to be called when user taps rating bar's ticks
* @param listener listener to set
*/
public void setListener(RatingListener listener);

/**
* Remove listener
*/
public void removeRatingListener();

/**
* Get the current rating shown
* @return rating
*/
public int getRating();

/**
* Set the rating to show
* @param rating new rating value
*/
public void setRating(int rating);

Tests

No test coverage is supplied so far - might be added later.
