网上大多的多宫格抽奖都是自定义view，如果view的布局不一样而且太多的话容易出现oom，不好管理
结合RecyclerView实现多宫格抽奖 效果图如下 满足所有矩形多宫格抽奖
9宫格
16宫格
25宫格
也可以不是正方形
比如
4行5列
acitivity的xml
<android.support.v7.widget.RecyclerView android:id="@+id/recycleView" android:layout_width="match_parent" android:layout_height="match_parent" />recyclerView的adapter下面LuckRecyclerViewAdapter

activity里的使用也很简单
public class TestActivity extends RxAppCompatActivity implements MultiMiyagiRaffle.OnLuckAnimationEndListener{ private RecyclerView recycleView; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_test); recycleView=findViewById(R.id.recycleView); //先初始化几行几列 MultiMiyagiRaffle.LINE=4; ----根据你的需要 MultiMiyagiRaffle.COLUMN=5; ----根据你的需要
StaggeredGridLayoutManager manager=new StaggeredGridLayoutManager(MultiMiyagiRaffle.COLUMN, StaggeredGridLayoutManager.VERTICAL); LuckRecyclerViewAdapter adapter=new LuckRecyclerViewAdapter(recycleView,initData(),this,this); recycleView.setLayoutManager(manager); recycleView.setAdapter(adapter); findViewById(R.id.iv_start).setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { adapter.multiMiyagiRaffle.startAnim(); } }); } private List<GiftBean> initData(){ List<GiftBean>giftBeans=new ArrayList<>(); for (int i=0;i<100;i++){ GiftBean giftBean=new GiftBean(R.drawable.aaa,10,"data"+i); giftBeans.add(giftBean); } //12个数据源 return giftBeans; } @Override public void onLuckAnimationEnd(int pos, String msg) { //打印抽奖结果 Toast.makeText(getApplicationContext(), "实际结果=="+msg, Toast.LENGTH_SHORT).show(); }}
