Paste or clone this library into the /libs
folder, in the root directory of your project. Create a new folder: /libs
if not already present. (This step is not required - only for keeping cleaner project structure)
Edit settings.gradle
by adding the library. You have also define a project directory for the library. Your settings.gradle
should look like below:
include ':app', ':SliderPreference'
project(':SliderPreference').projectDir = new File('libs/SliderPreference')
In app/build.gradle
add the SliderPreference library as a dependency:
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:21.0.3'
compile project(":SliderPreference")
}
Sync project, clean and build. You can use the SliderPreference as part of your project now.
Before you can add a SliderPreference
to your application, you must first add a library reference:
<!-- 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" />
<!-- 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:
<net.jayschwa.android.preference.SliderPreference
android:summary="This summary is static and boring"
android:defaultValue="0.5" />
Sliders are recommended by Android's official design documentation 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
with slider functionality. Various custom implementations can be found around the web, but many have issues such as:
This library aims to be as consistent as possible with the design pattern and Android's built-in Preference
implementations.
