RecycleView的Bug : java.lang.IndexOutOfBoundsException: Inconsistency detected. Invalid item position

最近在工作上，因為某些原因，需要很快速地刷新RecycleView內的元素，但是很常出現閃退，追了一下log，發現是下列的原因:

Bug 出現原因 :

再進行數據變動時，務必要保證 Adapter 中的數據和移除的數據保持一致，就是當你更新你的集合後，呼叫 notify 方法時， adapter 的更新預期結果和實際集合更新結果不同，就會出現此異常。

例如: 增加了兩條數據，但是 Adapter 的 notify 只增加 5 條數據，這種情況就屬於不一致，簡單來說 Apapter 有個 Size，你的資料結構集合也有 Size，這兩個 Size 在呼叫 notify 方法時必須保持相同。

解決方法 :

覆寫 xxxxLayoutManager(看你使用的是 LinearLayoutManager 或是 GridLayoutManager或其他)

public class RecyclerViewLinearLayoutManager extends LinearLayoutManager {
    public RecyclerViewLinearLayoutManager(Context context) {
        super( context );
    }

    public RecyclerViewLinearLayoutManager(Context context, int orientation, boolean reverseLayout) {
        super( context, orientation, reverseLayout );
    }

    public RecyclerViewLinearLayoutManager(Context context, AttributeSet attrs, int defStyleAttr, int defStyleRes) {
        super( context, attrs, defStyleAttr, defStyleRes );
    }

    @Override
    public void onLayoutChildren(RecyclerView.Recycler recycler, RecyclerView.State state) {
        try {
        //主要在這邊加入 try catch
            super.onLayoutChildren( recycler, state );
        } catch (IndexOutOfBoundsException e) {
            e.printStackTrace();
        }

    }
}

主要是在添加集合的時候，增加了一層 try catch去解決。
