解决 RecyclerView java.lang.IndexOutOfBoundsException

使用 RecyclerView 有时莫名其妙的就报数组越界异常了

1、重写 LinearLayoutManager

 public class WrapContentLinearLayoutManager extends LinearLayoutManager { 
   public WrapContentLinearLayoutManager(Context context) {
   	super(context);
   } 
   
   public WrapContentLinearLayoutManager(Context context, int orientation, boolean reverseLayout) {
   	super(context, orientation, reverseLayout);
   }
   
   public WrapContentLinearLayoutManager(Context context, AttributeSet attrs, int defStyleAttr, int defStyleRes) { 
   	super(context, attrs, defStyleAttr, defStyleRes);
    }
  
     @Override
     public void onLayoutChildren(RecyclerView.Recycler recycler, RecyclerView.State state) {
   	 try{
   		 super.onLayoutChildren(recycler, state);
   	 }catch (IndexOutOfBoundsException e) {
   		 e.printStackTrace(); 
   	 }
     }
  } 
 

2、设置 LayoutManager

  // mRecyclerView.setLayoutManager(new LinearLayoutManager(this)); 
  // 解决RecyclerView可能出现的holder数组越界Bug 
  mRecyclerView.setLayoutManager(
        new WrapContentLinearLayoutManager(this,LinearLayoutManager.VERTICAL, false));
