Android 滚动时间选择的代码实例
代码君哈哈 人气:0这篇文章主要介绍了Android 滚动时间选择的示例代码，文中通过示例代码介绍的非常详细，对大家的学习或者工作具有一定的参考学习价值，需要的朋友们下面随着小编来一起学习学习吧
效果图 复制代码直接用！！！！
1.导入依赖
implementation 'com.bigkoo:pickerview:2.1.0'
2.三个bean类
PickerViewData
public class PickerViewData implements IPickerViewData {
private String content;
public PickerViewData(String content) {
this.content = content;
}
public void setContent(String content) {
this.content = content;
}
@Override
public String getPickerViewText() {
return content;
}
}
ProvinceBean
public class ProvinceBean implements IPickerViewData {
private long id;
private String name;
private String description;
private String others;
public ProvinceBean(long id,String name,String description,String others){
this.id = id;
this.name = name;
this.description = description;
this.others = others;
}
public long getId() {
return id;
}
public void setId(long id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getDescription() {
return description;
}
public void setDescription(String description) {
this.description = description;
}
public String getOthers() {
return others;
}
public void setOthers(String others) {
this.others = others;
}
//这个用来显示在PickerView上面的字符串,PickerView会通过IPickerViewData获取getPickerViewText方法显示出来。
@Override
public String getPickerViewText() {
return name;
}
}
TimeBean
public class TimeBean implements IPickerViewData {
private String time;
public TimeBean(String time) {
this.time = time;
}
public String getTime() {
return time;
}
public void setTime(String time) {
this.time = time;
}
@Override
public String getPickerViewText() {
return time;
}
}
3,布局文件activity_main
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<TextView
android:layout_margin="50dp"
android:id="@+id/tvTime"
android:text="时间"
android:layout_width="match_parent"
android:layout_height="50dp"/>
<TextView
android:id="@+id/tvOptions"
android:layout_margin="50dp"
android:layout_below="@+id/tvTime"
android:text="条件"

<View
android:id="@+id/vMasker"
android:visibility="gone"
