使用方法

1. 项目依赖

项目根目录下build.gradle中加入：

allprojects {
    repositories {
        ...
        jcenter()
    }
}

添加依赖：

dependencies {
    implementation 'me.daemon:colorpickerview:x.y.z'
}

将其中的x、y、z替换为真实版本号：

2. 子模块依赖

Palette

implementation 'me.daemon:colorpickerview-palette-pie:x.y.z'

其中x、y、z替换为真实版本号

Brightness

implementation 'me.daemon:colorpickerview-brightness-simple:x.y.z'

其中x、y、z替换为真实版本号

Alpha

implementation 'me.daemon:colorpickerview-alpha-simple:x.y.z'

其中x、y、z替换为真实版本号

3. 使用

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        final ColorPickerView colorPickerView = findViewById(R.id.color_picker);
        // set palette painter
        colorPickerView.setPalettePainter(new PalettePiePainter());
        // set alpha painter
        colorPickerView.setAlphaPainter(new AlphaSimplePainter());
        // set brightness painter
