// demo dateset
List<String> mList = Arrays.asList("A", "B", "C");
mWheelPicker = (WheelPicker) findViewById(R.id.wheel_picker);
mWheelPicker.setOptions(new PicketOptions.Builder()
.linkage(false) // 是否联动
.dividedEqually(false) // 每列宽度是否均等分
.backgroundColor(Color.parseColor("#000000")) // 背景颜色
.dividerColor(Color.parseColor("#999999")) // 选中项分割线颜色
.build());
PickerAdapter adapter = new PickerAdapter() {
@Override
public int numberOfComponentsInWheelPicker(WheelPicker wheelPicker) {
// 需要多少列
return 2;
}
@Override
public int numberOfRowsInComponent(int component) {
// 某一列有多少行数据
switch (component) {
case 0:
return 10;
case 1:
return mList.size();
}
return 0;
}
@Override
public View onCreateView(ViewGroup parent, int row, int component) {
// 某行某列显示的View，String 数据可使用默认 StringItemView 类
String str = "";
switch (component) {
case 0:
str = "" + row;
break;
case 1:
str = mList.get(row);
break;
}
return new StringItemView(String.valueOf(str)).onCreateView(parent);
}
@Override
public void onBindView(ViewGroup parent, View convertView, int row, int component) {
// 回收的View，仅需根据某行某列刷新数据。String 数据可使用默认 StringItemView 类
String str = "";
switch (component) {
case 0:
str = "" + row;
break;
case 1:
str = mList.get(row);
break;
}
new StringItemView(String.valueOf(str)).onBindView(parent, convertView, row);
}
};
mWheelPicker.setAdapter(adapter);
mWheelPicker.setOnItemSelectedListener(new WheelPicker.OnItemSelectedListener() {
@Override
public void onItemSelected(WheelPicker parentView, int[] position) {
// 选中后的回调
s1 = "" + position[0];
s2 = mList.get(position[1]);
updateTextView();
}
});
