安卓选择器类库，包括日期及时间选择器（可设置范围）、单项选择器（可用于性别、职业、学历、星座等）、城市地址选择器（分省级、地级及县级）、数字选择器（可用于年龄、身高、体重、温度等）等…… 欢迎大伙儿在Issues提交你的意见或建议。 欢迎Fork & Pull requests贡献您的代码，大家共同学习【android-pickers交流群 : 456738690】。 查看更新日志
类库是基于Android-PickerView和AndroidPicker修改整合的,主要提供可以切换不同模式的view， 同时也优化了部分代码和适配问题，后期也会增加其他模式的切换。
“app”是Sample；“android-pickers”是library 包括WheelPicker、SinglePicker、DatePicker、TimePicker、LinkagePicker、AddressPicker、NumberPicker、CarNumberPicker等。
加载
repositories {
maven {
url "https://www.jitpack.io"
}
}
第二步，在项目的app模块下的build.gradle里加：
dependencies {
compile 'com.github.addappcn:android-pickers:1.0.0'
}
由于地址选择器使用了fastjson来解析，混淆时候需要加入以下类似的规则，不混淆Province、City等实体类。
-keepattributes InnerClasses,Signature
-keepattributes *Annotation*
-keep class cn.addapp.pickers.entity.** { *;}
继承自定义扩展选择器：
CustomPicker picker = new CustomPicker(this);
picker.setOffset(1);//显示的条目的偏移量，条数为（offset*2+1）
picker.setGravity(Gravity.CENTER);//居中
picker.setOnItemPickListener(new OnItemPickListener<String>() {
@Override
public void onItemPicked(int position, String option) {
showToast("index=" + position + ", item=" + option);
}
});
picker.show();内嵌视图选择器：
final TextView textView = findView(R.id.wheelview_tips);
WheelListView wheelListView = findView(R.id.wheelview_single);
wheelListView.setItems(new String[]{"少数民族", "贵州穿青人", "不在56个少数民族之列", "第57个民族"}, 1);
wheelListView.setSelectedTextColor(0xFFFF00FF);
LineConfig config = new LineConfig();
config.setColor(Color.parseColor("#26A1B0"));//线颜色
config.setAlpha(100);//线透明度
config.setRatio((float) (1.0 / 5.0));//线比率
config.setThick(ConvertUtils.toPx(this, 3));//线粗
config.setShadowVisible(false);
wheelListView.setLineConfig(config);
wheelListView.setOnWheelChangeListener(new WheelListView.OnWheelChangeListener() {
@Override
public void onItemSelected(boolean isUserScroll, int index, String item) {
textView.setText("index=" + index + ",item=" + item);
}
});
picker = new CarNumberPicker(this);
picker.setWeightEnable(true);
picker.setColumnWeight(0.5f,0.5f,1);
picker.setWheelModeEnable(true);
picker.setTextSize(18);
picker.setSelectedTextColor(0xFF279BAA);//前四位值是透明度
picker.setUnSelectedTextColor(0xFF999999);
picker.setCanLoop(true);
picker.setOffset(3);
picker.setOnMoreItemPickListener(new OnMoreItemPickListener<String>() {
@Override
public void onItemPicked(String s1, String s2, String s3) {
s3 = !TextUtils.isEmpty(s3) ? ",item3: "+s3 : "";
Toast.makeText(NextActivity.this, "item1: "+s1 +",item2: "+s2+ s3, Toast.LENGTH_SHORT).show();
}
});
picker.setOnMoreWheelListener(new OnMoreWheelListener() {
@Override
public void onFirstWheeled(int index, String item) {
textView.setText(item + ":" + picker.getSelectedSecondItem());
}
@Override
public void onSecondWheeled(int index, String item) {
textView.setText(picker.getSelectedFirstItem() + ":" + item);
}
@Override
public void onThirdWheeled(int index, String item) {
}
} );
ViewGroup viewGroup = findView(R.id.wheelview_container);
viewGroup.addView(picker.getContentView());选择器各个设置项：
boolean isChinese = Locale.getDefault().getDisplayLanguage().contains("中文");
OptionPicker picker = new OptionPicker(this,
isChinese ? new String[]{
"水瓶", "双鱼", "白羊", "金牛", "双子", "巨蟹",
"狮子", "处女", "天秤", "天蝎", "射手", "摩羯"
} : new String[]{
"Aquarius", "Pisces", "Aries", "Taurus", "Gemini", "Cancer",
"Leo", "Virgo", "Libra", "Scorpio", "Sagittarius", "Capricorn"
});
picker.setLabel(isChinese ? "座" : "");
picker.setCycleDisable(true);//禁用循环
picker.setLineConfig(config);
picker.setTopHeight(50);//顶部标题栏高度
picker.setTopLineColor(0xFF33B5E5);//顶部标题栏下划线颜色
picker.setTopLineHeight(1);//顶部标题栏下划线高度
picker.setTitleText(isChinese ? "请选择" : "Please pick");
picker.setTitleTextColor(0xFF999999);//顶部标题颜色
picker.setTitleTextSize(12);//顶部标题文字大小
picker.setCancelTextColor(0xFF33B5E5);//顶部取消按钮文字颜色
picker.setCancelTextSize(14);
picker.setSubmitTextColor(0xFF33B5E5);//顶部确定按钮文字颜色
picker.setSubmitTextSize(14);
picker.setTextColor(0xFFEE0000, 0xFF999999);//中间滚动项文字颜色
WheelView.LineConfig config = new WheelView.LineConfig();
config.setColor(0xFFEE0000);//线颜色
config.setAlpha(140);//线透明度
picker.setLineConfig(config);
picker.setBackgroundColor(0xFFE1E1E1);
//picker.setSelectedItem(isChinese ? "射手" : "Sagittarius");
picker.setSelectedIndex(10);//默认选中项
picker.setOnOptionPickListener(new OptionPicker.OnOptionPickListener() {
@Override
public void onOptionPicked(int index, String item) {
showToast("index=" + index + ", item=" + item);
}
});
picker.show();
