Installation Guide

Let’s dive into how you can install ColorPickerPreference via Gradle or Android Studio:

Installation through Gradle

implementation net.margaritov.preference.colorpicker.ColorPickerPreference:ColorPickerPreference:1.0.0

Installation in Android Studio

1. Paste or clone the library into the libs folder in your project’s root directory. If the libs folder isn’t already present, create one for a cleaner project structure.
2. Edit settings.gradle to include the library and define its project directory:

   include :app, :ColorPickerPreference
   project(:ColorPickerPreference).projectDir = new File(applibsColorPickerPreference)

3. In app/build.gradle, add the ColorPickerPreference library as a dependency:

   dependencies {
       implementation fileTree(dir: libs, include: [*.jar])
       implementation com.android.support:appcompat-v7:21.0.3
       implementation project(:ColorPickerPreference)
   }

4. Sync your project, clean, and build. You can now use the ColorPickerPreference library in your project!

Installation in Eclipse

1. You first need to add a library reference to utilize ColorPickerPreference.
2. Clone or download a copy of the library.
3. Import the library into Eclipse by navigating to: File menu – Import – Existing Project into Workspace.
4. Finally, open your application’s project properties and add the library reference to ColorPickerPreference.

Usage Examples

To use the ColorPickerPreference in your application, you can see some tests implemented as follows:

<net.margaritov.preference.colorpicker.ColorPickerPreference
    android:key="color1"
    android:title="@string/color1_title"
    android:summary="@string/color1_summary"
    android:defaultValue="@color/pumpkin_orange"
    alphaSlider="true" />

For enabling the Alpha Slider dynamically, you can use the following function call in your code:

setAlphaSliderEnabled(boolean enable)

Troubleshooting Common Issues

• Project not syncing: Ensure that all paths and dependencies in your gradle files are correct. Check the console for error messages.
• Library not found: Make sure the ColorPickerPreference folder is correctly placed in the libs directory and properly referenced in settings.gradle.
• App crashes when using color picker: Double-check the XML attributes and ensure they are correctly defined as per the library’s documentation.
