如何引入

Gradle引入

step 1

Add the JitPack repository to your build file

	allprojects {
			repositories {
				...
				maven { url 'https://jitpack.io' }
			}
		}

Step 2

Add the dependency

dependencies {
	         implementation 'com.github.itlwy:PaginationExample:0.0.20'
	}

简单使用

组合RecycleView使用

此时使用的是PaginationRecycleView类

1. activity_main.xml

   ...
   <com.lwy.paginationlib.PaginationRecycleView
           android:id="@+id/pagination_rcv"
           android:layout_width="match_parent"
           android:layout_height="match_parent"
           android:layout_marginBottom="8dp"
           app:number_tip_count="5"
           app:rect_size="30dp"
           app:selected_color="@color/indicator_rect_selected"
           app:text_size="14sp"
           app:unselected_color="@color/indicator_rect_unselected"
           />	
   ...

2. MainActivity.java

    ...
     @Override
       protected void onCreate(Bundle savedInstanceState) {
   		mPaginationRcv = findViewById(R.id.pagination_rcv);
           mAdapter = new CustomAdapter(this, 99);
           mPaginationRcv.setAdapter(mAdapter);
   //        mPaginationRcv.setPerPageCountChoices(perPageCountChoices);
           GridLayoutManager layoutManager = new GridLayoutManager(this, 3);
           mPaginationRcv.setLayoutManager(layoutManager);
           mPaginationRcv.setListener(new PaginationRecycleView.Listener() {
               @Override
               public void loadMore(int currentPagePosition, int nextPagePosition, int perPageCount, int dataTotalCount) {
            		// nextPagePosition为将要加载的页码，即需要加载数据的页
            		// perPageCount 每页展示的数量
                  //TODO : 此处进行异步数据加载
                  //TODO : 完成加载后通知分页控件(注意此处应该是在主线程运行)，如下
                   mAdapter.setDatas(nextPagePosition, data);
                   mPaginationRcv.setState(PaginationRecycleView.SUCCESS);
                   
               }
   
               @Override
               public void onPerPageCountChanged(int perPageCount) {
   				// "x条/每页"Spinner选中值改变时触发
               }
           });
           mAdapter.setOnItemClickListener(this);
    }
            @Override
       public void onItemClick(View view, RecyclerView.ViewHolder holder, int position) {
           JSONObject item = mAdapter.getCurrentPageItem(position);  // 此处position返回的是recycleview的位置，所以取当前页显示列表的项
           Toast.makeText(this, item.optString("name"), Toast.LENGTH_LONG).show();
       }
   ...

3. CustomAdapter

   class CustomAdapter extends PaginationRecycleView.Adapter<JSONObject, ViewHolder> {
   
   
           private Context mContext;
   
           public CustomAdapter(Context context, int dataTotalCount) {
               super(dataTotalCount);
               mContext = context;
           }
   
   
           @Override
           public void bindViewHolder(ViewHolder viewholder, JSONObject data) {
               viewholder.setText(R.id.text, data.optString("name"));
           }
   
           @Override
           public ViewHolder createViewHolder(@NonNull ViewGroup parent, int viewTypea) {
               return ViewHolder.createViewHolder(mContext, parent, R.layout.item_list);
           }
       }

   布局文件中的属性说明:

   app:number_tip_count="5"   // 数字指示器显示的数量，默认是5
   app:rect_size="30dp"		// 圆角矩形的大小(正方形)
   app:selected_color="@color/indicator_rect_selected"  // 选中的颜色(包含框和字体)
   app:text_size="14sp"  // 字体大小
   app:unselected_color="@color/indicator_rect_unselected" 未选中的颜色(包含框和字体)
   

单独使用

​ 此时使用的是PaginationIndicator类，布局如下：

...
<com.lwy.paginationlib.PaginationIndicator
    android:id="@+id/indicator"
    android:layout_width="match_parent"
    app:number_tip_count="5"
    app:rect_size="30dp"
    app:selected_color="@color/indicator_rect_selected"
    app:text_size="14sp"
    app:unselected_color="@color/indicator_rect_unselected"
    android:layout_height="wrap_content">
...

​ 说明如上述

​ 代码如下：

... 
private int[] perPageCountChoices = {10, 20, 30, 50};
... 
mIndicatorView = (PaginationIndicator) findViewById(R.id.indicator);
        mIndicatorView.setTotalCount(99);  // 设置数据源总数量即可
        mIndicatorView.setPerPageCountChoices(perPageCountChoices); // 选填
        mIndicatorView.setListener(new PaginationIndicator.OnChangedListener() {
            @Override
            public void onPageSelectedChanged(int currentPapePos, int lastPagePos, int totalPageCount, int total) {
                Toast.makeText(MainActivity.this, "选中" + currentPapePos + "页", Toast.LENGTH_LONG).show();
            }

            @Override
            public void onPerPageCountChanged(int perPageCount) {
				// x条/页 选项改变时触发
            }
        });
...

​ 相关说明已在代码里注释，详细可参考demo，谢谢
