#### 1、轮播图1
![轮播图](./static/轮播图_2022-01-13-14-06-11.gif)

参考代码示例如下：

```
        
        ImageView iv1 = (ImageView) LayoutInflater.from(this).inflate(R.layout.banner_item,bannerViewPager,false);
        ImageView iv2 = (ImageView) LayoutInflater.from(this).inflate(R.layout.banner_item,bannerViewPager,false);
        ImageView iv3 = (ImageView) LayoutInflater.from(this).inflate(R.layout.banner_item,bannerViewPager,false);
        ImageView iv4 = (ImageView) LayoutInflater.from(this).inflate(R.layout.banner_item,bannerViewPager,false);
        ImageView iv5 = (ImageView) LayoutInflater.from(this).inflate(R.layout.banner_item,bannerViewPager,false);
        final ImageView iv6 = (ImageView) LayoutInflater.from(this).inflate(R.layout.banner_item,bannerViewPager,false);

        iv1.setImageResource(R.mipmap.ic_img01);
        iv2.setImageResource(R.mipmap.ic_img02);
        iv3.setImageResource(R.mipmap.ic_img03);
        iv4.setImageResource(R.mipmap.ic_img04);
        iv5.setImageResource(R.mipmap.ic_img05);
        iv6.setImageResource(R.mipmap.ic_img06);

        //一开始只添加5个Item
        final List<ImageView> mViews = new ArrayList<>();
        mViews.add(iv1);
        mViews.add(iv2);
        mViews.add(iv3);
        mViews.add(iv4);
        mViews.add(iv5);
        
        bannerViewPager = findViewById(R.id.banner);

        ViewPagerAdapter  mAdapter = new ViewPagerAdapter(mViews, new OnPageClickListener() {
            @Override
            public void onPageClick(View view, int position) {
                Log.d("cylog","position:"+position);
            }
        });
        bannerViewPager.setAdapter(mAdapter);

```

1. 优雅的实现手动滑到最后一页再向后滑动回到第一页
2. 自动滑动优雅平缓实现且平缓的和手动滑动切换

###### 优雅的实现手动滑到最后一页再向后滑动回到第一页

```
int scrollState = ViewPager.SCROLL_STATE_IDLE;
    private int lastValue = -1;
    private boolean canMove = true;
    ViewPager.OnPageChangeListener onPageChangeListener = new ViewPager.OnPageChangeListener() {
        @Override
        public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {
            Log.i(TAG, "position=" + position + ",positionOffset=" + positionOffset + " ,positionOffsetPixels=" + positionOffsetPixels);
            if (scrollState == ViewPager.SCROLL_STATE_DRAGGING) {
                if (lastValue > positionOffsetPixels) {
                    Log.d(TAG, "向右滑动");
                } else if (lastValue < positionOffsetPixels) {
                    Log.d(TAG, "向左滑动");
                } else {
                    Log.e(TAG, "暂无法判断滑动方向");
                }
                if (0.0f == positionOffset && 0 == positionOffsetPixels) {
                    canMove = false;
                } else {
                    canMove = true;
                }
            }
            lastValue = positionOffsetPixels;
        }

        @Override
        public void onPageSelected(int i) {
            Log.d(TAG, "onPageSelected index=" + i);
            setSelectedIndicator(i);
        }

        @Override
        public void onPageScrollStateChanged(int i) {
            Log.d(TAG, "onPageScrollStateChanged i=" + i);

            if (ViewPager.SCROLL_STATE_DRAGGING == scrollState
                    && i == ViewPager.SCROLL_STATE_IDLE
                    && !canMove
            ) {
                if ( 0==viewPager.getCurrentItem() ) {
                    Log.d(TAG, "已在第一页了" + viewPager.getCurrentItem());
                }else{
                    Log.d(TAG, "已在最后一页了" + viewPager.getCurrentItem());
                    viewPager.setCurrentItem(0);
                }
            }
            scrollState = i;
        }
    };    
```
滑动到第一页或者最后一页 滑动参数

position=0,positionOffset=0.0 ,positionOffsetPixels=0

position=4,positionOffset=0.0 ,positionOffsetPixels=0

一共4页

过程中判断是从ViewPager.SCROLL_STATE_DRAGGING滑动到停止滑动ViewPager.SCROLL_STATE_IDLE，在状态还保存为ViewPager.SCROLL_STATE_DRAGGING依据canMove滑动标识为停止。 接着判断当前的页数在第一还是最后一页来判断。

###### 自动滑动优雅平缓实现且平缓的和手动滑动切换

```
Handler handler = new Handler();
    //the interval between rollings
    private int mAutoRollingTime = 5000;
    private int mReleasingTime = 0;
    /**
     * This runnable decides the viewpager should roll to next page or wait.
     */
    private Runnable mAutoRollingTask = new Runnable() {
        @Override
        public void run() {
            if (isFinishing())
                return;
            int now = (int) System.currentTimeMillis();
            int timediff = mAutoRollingTime;
            if (mReleasingTime != 0) {
                timediff = now - mReleasingTime;
            }
            if (scrollState == ViewPager.SCROLL_STATE_IDLE) {
                //if user's finger just left the screen,we should wait for a while.
                if (timediff >= mAutoRollingTime * 0.8) {
                    if (viewPager.getCurrentItem() == mViews.size() - 1) {
                        viewPager.setCurrentItem(0, true);
                    } else {
                        viewPager.setCurrentItem(viewPager.getCurrentItem() + 1, true);
                    }
                }
            }
        }
    };
    
     @Override
        public void onPageScrollStateChanged(int i) {
            Log.d(TAG, "onPageScrollStateChanged i=" + i);
            if (i!=ViewPager.SCROLL_STATE_IDLE) {
                handler.removeCallbacks(mAutoRollingTask);
            }else {
                handler.postDelayed(mAutoRollingTask, mAutoRollingTime);
            }
            ...
            
```



#### 2、多功能指示器

![](./static/指示器.png)

xml：

```
<com.example.indicatorlib.views.PageIndicatorView
        android:id="@+id/pageIndicatorView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_centerHorizontal="true"
        android:layout_marginBottom="48dp"
        app:layout_constraintTop_toBottomOf="@id/banner"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        attrs:piv_padding="12dp"
        attrs:piv_radius="8dp" />
 
```

java

```
 PageIndicatorView pageIndicatorView = findViewById(R.id.pageIndicatorView);
        pageIndicatorView.setViewPager(bannerViewPager.getViewPager());
        pageIndicatorView.setAnimationType(AnimationType.WORM);//动画效果设置

```

    。。。

 ```
 
 StockActivity#initView()

```

。。。
final StickyHeadContainer container = (StickyHeadContainer) findViewById(R.id.shc);
        final TextView tvStockName = (TextView) container.findViewById(R.id.tv_stock_name);
        final CheckBox checkBox = (CheckBox) container.findViewById(R.id.checkbox);
        final TextView tvMore = (TextView) container.findViewById(R.id.tv_stock_more);
        final ImageView more = (ImageView) container.findViewById(R.id.iv_more);

            @Override
            public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {

            public void onDataChange(int pos) {
                mStickyPosition = pos;
                StockEntity.StockInfo item = mAdapter.getData().get(pos).getData();
                tvStockName.setText(item.stickyHeadName);
                checkBox.setChecked(item.check);
            }
        });
        more.setOnClickListener(new View.OnClickListener() {

                    Toast.makeText(StockActivity.this, "点击了TYPE_DATA Item", Toast.LENGTH_SHORT).show();
                }else if(data.getItemType() == RecyclerViewAdapter.TYPE_STICKY_HEAD){
                    Toast.makeText(StockActivity.this, "点击了TYPE_STICKY_HEAD Item", Toast.LENGTH_SHORT).show();
                }
            }
        });
        。。。

```

##### （亲测）如果不设置 mDataCallback 则不显示头部悬浮吸顶

一定要进行下面的初始化设置

```
container.setDataCallback(new StickyHeadContainer.DataCallback() {
            @Override
            public void onDataChange(int pos) {
                mStickyPosition = pos;
                StockEntity.StockInfo item = mAdapter.getData().get(pos).getData();
                tvStockName.setText(item.stickyHeadName);
                checkBox.setChecked(item.check);
            }
        });

```

```
public void onDataChange(int stickyHeadPosition) {
        if (mDataCallback != null && mLastStickyHeadPosition != stickyHeadPosition) {
            mDataCallback.onDataChange(stickyHeadPosition);
        }
        if (null == mDataCallback) {
            Log.w(TAG, "mDataCallback is null");
        }
        mLastStickyHeadPosition = stickyHeadPosition;
    }

```

#### 4、日期时间选择器
效果如下图：
![](./static/日期时间滚轮选择器.gif)

###### 库地址
[https://github.com/ycuwq/DatePicker](https://github.com/ycuwq/DatePicker)

###### 使用
使用上比较简单

```
<com.ycuwq.datepicker.date.DatePicker

        app:layout_constraintTop_toTopOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        android:id="@+id/dayPicker_dialog"
        android:layout_width="match_parent"
        android:layout_height="wrap_content">
    </com.ycuwq.datepicker.date.DatePicker>

    <com.ycuwq.datepicker.time.HourAndMinutePicker
        android:id="@+id/hour_min_picker_dialog"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintTop_toBottomOf="@id/dayPicker_dialog"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        />
        
```

java

```
实现如下接口即可
		YearPicker.OnYearSelectedListener
		,MonthPicker.OnMonthSelectedListener
		, DayPicker.OnDaySelectedListener

```
