WheelView ========= Android滚动选择控件 <img src='https://raw.githubusercontent.com/wangjiegulu/WheelView/master/image/image01.png' height='500px'/> <img src='https://raw.githubusercontent.com/wangjiegulu/WheelView/master/image/image02.png' height='500px'/> <img src='https://raw.githubusercontent.com/wangjiegulu/WheelView/master/image/image03.png' height='500px'/> 实现Android竖直滚动选择功能 注意： 1. 此demo中注解、日志等功能使用了AndroidInject（https://github.com/wangjiegulu/androidInject） 和AndroidBucket（https://github.com/wangjiegulu/AndroidBucket）项目 2. 此demo中每一个滑动的选项都是一个View，未使用View的缓存，待优化！ 使用方式： /** * Author: wangjie * Email: tiantian.china.2@gmail.com * Date: 7/1/14. */ @AILayout(R.layout.main) public class MainActivity extends AIActivity { public static final String TAG = MainActivity.class.getSimpleName(); private static final String[] PLANETS = new String[]{"Mercury", "Venus", "Earth", "Mars", "Jupiter", "Uranus", "Neptune", "Pluto"}; @AIView(R.id.main_wv) private WheelView wva; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); wva.setOffset(1); wva.setItems(Arrays.asList(PLANETS)); wva.setOnWheelViewListener(new WheelView.OnWheelViewListener() { @Override public void onSelected(int selectedIndex, String item) { Logger.d(TAG, "selectedIndex: " + selectedIndex + ", item: " + item); } }); } @AIClick({R.id.main_show_dialog_btn}) public void onClickCallbackSample(View view) { switch (view.getId()) { case R.id.main_show_dialog_btn: View outerView = LayoutInflater.from(context).inflate(R.layout.wheel_view, null); WheelView wv = (WheelView) outerView.findViewById(R.id.wheel_view_wv); wv.setOffset(2); wv.setItems(Arrays.asList(PLANETS)); wv.setSeletion(3); wv.setOnWheelViewListener(new WheelView.OnWheelViewListener() { @Override public void onSelected(int selectedIndex, String item) { Logger.d(TAG, "[Dialog]selectedIndex: " + selectedIndex + ", item: " + item); } }); new AlertDialog.Builder(context) .setTitle("WheelView in Dialog") .setView(outerView) .setPositiveButton("OK", null) .show(); break; } } } License ======= Copyright 2014 Wang Jie Licensed under the Apache License, Version 2.0 (the "License"); you may not use this file except in compliance with the License.
