Android RecyclerView多布局加载添加以及删除

RecyclerView多布局加载

    1、可以实时添加删除

2、解决了刷新RecyclerView是崩掉的问题

RecyclerView在刷新数据的时候会出现以下异常：

java.lang.IndexOutOfBoundsException: Inconsistency detected. Invalid view holder adapter positionViewHolder{431a7450 position=1 id=-1, oldPos=-1, pLpos:-1 scrap [attachedScrap] tmpDetached no parent}  
    at android.support.v7.widget.RecyclerView$Recycler.validateViewHolderForOffsetPosition(RecyclerView.java:4251)  
    at android.support.v7.widget.RecyclerView$Recycler.getViewForPosition(RecyclerView.java:4382)  
    at android.support.v7.widget.RecyclerView$Recycler.getViewForPosition(RecyclerView.java:4363)  
    at android.support.v7.widget.LinearLayoutManager$LayoutState.next(LinearLayoutManager.java:1961)  
    at android.support.v7.widget.LinearLayoutManager.layoutChunk(LinearLayoutManager.java:1370)  
    at android.support.v7.widget.LinearLayoutManager.fill(LinearLayoutManager.java:1333)  
    at android.support.v7.widget.LinearLayoutManager.onLayoutChildren(LinearLayoutManager.java:562)  
    at android.support.v7.widget.RecyclerView.dispatchLayout(RecyclerView.java:2900)  
    at android.support.v7.widget.RecyclerView.onLayout(RecyclerView.java:3071)  
    at android.view.View.layout(View.java:14828)  

......

这个直接在底层就崩掉了，后来在网上看了一个方法这样解决的

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();  
        }  
    }  
}  

然后设置

mRecyclerView.setLayoutManager(new WrapContentLinearLayoutManager(this, LinearLayoutManager.VERTICAL, false));
