This is an iOS-like PickerView control with a time selector and option selector. The detailed features of the new version are as follows:
——TimePickerView time picker, supports year, month, day, hour and minute, year, month, day, year, month, hour and minute and other formats. ——OptionsPickerView option selector supports first, second and third level option selection, and can set whether to be linked.
- Support three-level linkage
- Set whether to link
- Set loop mode
- Support custom layout.
- Support item separator setting.
- Support item spacing setting.
- Time selector supports start and end date settings.
- Supports the display, hiding and customization of unit (label) options such as "year, month, day, hour, minute, second", "province, city, district" and other options.
- Support custom text, color, text size and other attributes
- When the text length of the Item is too long, the text will be adaptively scaled to the length of the Item to avoid the problem of incomplete display.
- Support Dialog mode.
- Support custom settings container.
- Real-time callback.
If you are interested in studying the implementation mechanism of the 3D scroll wheel effect and want to thoroughly study the source code, you can read this blog:
-
Note: When we set the starting position of the time, we need to pay special attention to the setting of the month.
-
Reason: The months inside the Calendar component start from 0, that is, 0-11 represents the months from January to December.
-
Incorrect use cases: startDate.set(2013,1,1); endDate.set(2020,12,1); *Correct use case: startDate.set(2013,0,1); endDate.set(2020,11,1);
- Fixed: The problem of lunar day occasionally crossing the boundary.
- Optimization: Fixed the problem of default capitalization in English and Chinese in the display layout.
- New: The maximum number of visible items provides API for developers to set. (setItemVisibleCount())
- Newly added: The transparency of the scroll wheel gradually changes from the middle to both sides, and provides switch API settings. (isAlphaGradient(true))
- New: Selected item circular dividing line style. (DividerType.CIRCLE)
- Update the gradle version, and change the wheelview basic library from compile to api dependency to avoid being unable to be introduced in gradle 5.0+ version.
- Fixed setTextXOffset assignment problem.
- Fixed the problem that when WheelView is initialized, the data is empty, resulting in height=0, causing it to not be displayed.
- Added a click event listening entry for the cancel button.
- Parameter annotations are added to standardize data types.
- The setBackgroundId method is abandoned and the updated method is named setOutSideColor.

6. If you only need the WheelView basic control to extend the implementation logic by itself, you can directly add the basic control library, Gradle depends on:
compile 'com.contrarywind:wheelview:4.1.0'xml layout:
<com.contrarywind.view.WheelView
android:id="@+id/wheelview"
android:layout_width="match_parent"
android:layout_height="wrap_content" />Java code:
WheelView wheelView = findViewById(R.id.wheelview);
wheelView.setCyclic(false);
final List<String> mOptionsItems = new ArrayList<>();
mOptionsItems.add("item0");
mOptionsItems.add("item1");
mOptionsItems.add("item2");
wheelView.setAdapter(new ArrayWheelAdapter(mOptionsItems));
wheelView.setOnItemSelectedListener(new OnItemSelectedListener() {
@Override
public void onItemSelected(int index) {
Toast.makeText(MainActivity.this, "" + mOptionsItems.get(index), Toast.LENGTH_SHORT).show();
}
});Rendering (They use my library for the condition selector in the "Pocket Life" of China Merchants Bank Credit Card, you can use it as a reference for actual projects)
