bugly上的報(bào)錯(cuò)信息如下：
AndroidRuntime: java.lang.NullPointerException: Attempt to invoke virtual method 'void androidx
.recyclerview.widget.RecyclerView$OnScrollListener.onScrolled(androidx.recyclerview.widget
.RecyclerView, int, int)' on a null object reference
具體業(yè)務(wù)代碼為：
public void setDate(InformationChannel channel){
final RecyclerView.OnScrollListener onScrollListener = new RecyclerView.OnScrollListener()
{
@Override
public void onScrolled(@NonNull RecyclerView recyclerView, int dx, int dy)
{
if (mLoadDataListener != null)
{
mLoadDataListener.backScrolled(FishView.this);
}
}
};
this.mListView = new RecyclerView(context);
this.mListView.setLayoutManager(new LinearLayoutManager(context, RecyclerView.VERTICAL, false));
this.mListView.setAdapter(mChannelAdapter);
this.mListView.addOnScrollListener(onScrollListener);
this.mListView.setOverScrollMode(OVER_SCROLL_NEVER);
this.mListView.setVerticalScrollBarEnabled(false);
this.addView(this.mListView, new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT));
this.setPullDownEnabled(true);
this.setPullUpEnabled(true);
}
目前分析可能是因?yàn)閛nScrollListener 定義在方法內(nèi)部搬瑰，方法結(jié)束之后歼疮，可能就被釋放回收跨琳，所以導(dǎo)致空指針的產(chǎn)生哪痰。
