# PickerView [](https://github.com/duanhong169/PickerView/releases) [](https://developer.android.com/index.html) [](https://android-arsenal.com/details/1/7056) [](https://github.com/duanhong169/PickerView/blob/master/LICENSE) [](https://appcenter.ms)
Android滚动选择器
## 使用方法
### 1. 添加依赖
> 注：${latestVersion}请替换为当前最新版本号，见[releases](https://github.com/duanhong169/PickerView/releases)。
gradle：
```groovy
implementation 'com.github.duanhong169:picker-view:${latestVersion}'
```
maven：
```xml
com.github.duanhong169
picker-view
${latestVersion}
pom
```
### 2. 集成到项目中
#### 2.1 集成PickerView
添加到layout文件中：
```xml
```
##### 使用列表作为数据源
```java
List items = new ArrayList<>();
for (int i = 0; i < 42; i++) {
items.add(new Item("Item " + i));
}
pickerView.setItems(Item.sampleItems(), item -> textView.setText(item.getText()));
```
##### 实现Adapter作为数据源
配置数据源：
```java
PickerView.Adapter adapter = new PickerView.Adapter() {
@Override
public int getItemCount() {
return 42;
}
@Override
public String getText(int index) {
return "Item " + index;
}
};
pickerView.setAdapter(adapter);
```
监听选择事件：
```java
pickerView.setOnSelectedItemChangedListener((pickerView, previousPosition, selectedItemPosition) ->
textView.setText(pickerView.getAdapter().getText(selectedItemPosition)));
```
#### 2.2 集成DivisionPickerView
添加到layout文件中：
```xml
```
构建省市区数据源：
> 参考[Divisions.java](app/src/main/java/top/defaults/pickerviewapp/Divisions.java)
设置数据源并监听选择事件
```java
final List divisions = Divisions.get(this);
divisionPicker.setDivisions(divisions);
divisionPicker.setOnSelectedDateChangedListener(division -> textView.setText(Division.Helper.getCanonicalName(division)));
```
#### 2.3 集成DateTimePickerView
添加到layout文件中：
```xml
```
设置初始日期：
```java
dateTimePickerView.setStartDate(Calendar.getInstance());
// 注意：月份是从0开始计数的
dateTimePickerView.setSelectedDate(new GregorianCalendar(2017, 6, 27, 21, 30));
```
监听选择事件：
```java
dateTimePickerView.setOnSelectedDateChangedListener(new DateTimePickerView.OnSelectedDateChangedListener() {
@Override
public void onSelectedDateChanged(Calendar date) {
int year = date.get(Calendar.YEAR);
int month = date.get(Calendar.MONTH);
int dayOfMonth = date.get(Calendar.DAY_OF_MONTH);
int hour = date.get(Calendar.HOUR_OF_DAY);
int minute = date.get(Calendar.MINUTE);
String dateString = String.format(Locale.getDefault(), "%d年%02d月%02d日%02d时%02d分", year, month + 1, dayOfMonth, hour, minute);
textView.setText(dateString);
Log.d(TAG, "new date: " + dateString);
}
});
```
