Android -- [SelfView] 自定义弹窗式颜色选择器
PS:
1. 弹框式显示；
2. 支持透明度设置；
3. 支持拖动控件选择颜色；
4. 支持 ARGB | HEX 数值填写预览颜色并返回；
5. 输出支持Hex 和 Int 两种格式；
效果
使用方法：
java
//activity 内
//1. 声明
private VirgoColorBoard colorBoard;
//2. 初始化
colorBoard = new VirgoColorBoard(this);//用content会报错
//监听回调：
//a. Avtivity -> implements VirgoColorBoard.ColorCallback
//b. 直接 new VirgoColorBoard.ColorCallback(){...}
colorBoard.setCallback(this);
//弹窗宽、高、透明属性设置，按需
colorBoard.setDialogAlpha(1);
colorBoard.setDialogWidth(768);
colorBoard.setDialogHeight(660);
//回调口执行自定义处理
@Override
public void onPick(int color) {
//do something
}
@Override
public void onPickStr(String hex) {
//do something
