1、通过SVN或GIT工具下载本项目，复制“framework-picker”到你的电脑上；
2、用Android Studio或IntelliJ IDEA打开你的项目，New->Import Module，选择“framework-picker”；
3、修改你的项目的build.gradle，加入依赖项“framework-picker”，如：
dependencies {
compile 'com.android.support:support-v4:+'
compile project(':framework-picker')
}
注：
滑轮选择器的名称较长时，将以“...”显示超出的部分。
支持android2.2+，项目编码为UTF-8。

public void onSubmit(Date result) {
}
});

option3_2_1.add("北京市");
option3_2.add(option3_2_1);
option3.add(option3_1);
option3.add(option3_2);
OptionPicker picker = new OptionPicker(this);
picker.setOptions(option1, option2, option3);
picker.setCurrentOptions(0, 1, 2);
picker.setOnWheelListener(new WheelPicker.OnWheelListener<int[]>() {
@Override
public void onSubmit(int[] result) {
String province = option1.get(result[0]);
String city = option2.get(result[0]).get(result[1]);
String district = option3.get(result[0]).get(result[1]).get(result[2]);
String result = province + "-" + city + "-" + district;
}
});
picker.showAtBottom();颜色选择器：
ColorPicker picker = new ColorPicker(this);
picker.setInitColor(0xDD00DD);
