Android Slider Preference Library
|
||||
=================================
|
||||
|
||||
|
||||
|
||||
## Overview
|
||||
|
||||
* Slider represents a `float` between `0.0` and `1.0`
|
||||
* Access with `SliderPreference.getValue()` or [`SharedPreferences.getFloat()`][shar]
|
||||
* Supports multiple summaries (e.g. "Low", "Medium", "High") and selects one based on the slider's position
|
||||
* Java: `SliderPreference.setSummary(CharSequence[] summaries)`
|
||||
* XML: `android:summary="@array/string_array_of_summaries"`
|
||||
* A single `String` still works too
|
||||
* Subclass of [`DialogPreference`][diag]
|
||||
* Supports all [dialog-specific attributes][datr] such as `android:dialogMessage`
|
||||
* Visually-consistent with Android's built-in preferences
|
||||
* Less error-prone than displaying the slider directly on the settings screen
|
||||
* [MIT License](#license)
|
||||
|
||||
[datr]: https://developer.android.com/reference/android/preference/DialogPreference.html#lattrs "DialogPreference attributes"
|
||||
[diag]: https://developer.android.com/reference/android/preference/DialogPreference.html "DialogPreference"
|
||||
[shar]: https://developer.android.com/reference/android/content/SharedPreferences.html#getFloat(java.lang.String,%20float) "getFloat()"
|
||||
|
||||
## How To Use
|
||||
|
||||
### Add the library to your application
|
||||
|
||||
Before you can add a `SliderPreference` to your application, you must first add a library reference:
|
||||
|
||||
1. Clone or download a copy of the library
|
||||
2. Import the library into Eclipse: File menu -> Import -> Existing Project into Workspace
|
||||
3. Open your application's project properties and [add a library reference][ref] to "SliderPreference"
|
||||
|
||||
[ref]: https://developer.android.com/tools/projects/projects-eclipse.html#ReferencingLibraryProject
|
||||
|
||||
### Add a slider to your application
|
||||
|
||||
``` XML
|
||||
<!-- preferences.xml -->
|
||||
<net.jayschwa.android.preference.SliderPreference
|
||||
android:key="my_slider"
|
||||
android:title="@string/slider_title"
|
||||
android:summary="@array/slider_summaries"
|
||||
android:defaultValue="@string/slider_default"
|
||||
android:dialogMessage="@string/slider_message" />
|
||||
```
|
||||
``` XML
|
||||
<!-- strings.xml -->
|
||||
<string name="slider_title">Temperature</string>
|
||||
<string-array name="slider_summaries">
|
||||
<!-- You can define as many summaries as you'd like -->
|
||||
<!-- The active summary will reflect the preference's current value -->
|
||||
<item>Freezing</item> <!-- 0.00 to 0.25 -->
|
||||
<item>Chilly</item> <!-- 0.25 to 0.50 -->
|
||||
<item>Warm</item> <!-- 0.50 to 0.75 -->
|
||||
<item>Boiling</item> <!-- 0.75 to 1.00 -->
|
||||
</string-array>
|
||||
<item name="slider_default" format="float" type="string">0.5</item>
|
||||
<string name="slider_message">Optional message displayed in the dialog above the slider</string>
|
||||
```
|
||||
|
||||
It is possible to define the default value directly in the attribute. The summary can also be a regular string, instead of a string array:
|
||||
|
||||
``` XML
|
||||
<net.jayschwa.android.preference.SliderPreference
|
||||
android:summary="This summary is static and boring"
|
||||
android:defaultValue="0.5" />
|
||||
```
|
||||
|
||||
## Background
|
||||
|
||||
Sliders are recommended by Android's official [design documentation][ptrn] for specific types of settings:
|
||||
|
||||
> Use this pattern for a setting where the range of values are not discrete and fall along a continuum.
|
||||
>
|
||||
> 
|
||||
|
||||
Despite this recommendation, the Android SDK does not actually provide a [`Preference`][pref] with slider functionality. Various custom implementations can be found around the web, but many have issues such as:
|
||||
|
||||
* The slider is displayed directly on the settings screen
|
||||
* Higher chance of accidental clicks
|
||||
* No way to confirm or cancel potential changes
|
||||
* Discrete values are displayed to the user
|
||||
* Not ideal for this design pattern
|
||||
|
||||
This library aims to be as consistent as possible with the design pattern and Android's built-in [`Preference`][pref] implementations.
