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
-
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" /> ...
-
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(); } ...
-
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
}
});
...
