關於RecyclerView設置了適配器數據不顯示問題

List<String> mDatas = new ArrayList<String>();mDatas.add( "item1");mDatas.add( "item2");ReportMsgAdapter recycleAdapter= new ReportMsgAdapter(mContext , mDatas );RecyclerView reportList=(RecyclerView)view.findViewById(R.id.report_list);reportList.setAdapter(recycleAdapter);

結果：

RecyclerView不顯示List的內容

原因：

沒有設置布局管理器

LinearLayoutManager layoutManager = new LinearLayoutManager(mContext );//設置布局管理器reportList.setLayoutManager(layoutManager);

正確打開方式

List<String> mDatas = new ArrayList<String>();mDatas.add( "item1");mDatas.add( "item2");ReportMsgAdapter recycleAdapter= new ReportMsgAdapter(mContext , mDatas );RecyclerView reportList=(RecyclerView)view.findViewById(R.id.report_list);LinearLayoutManager layoutManager = new LinearLayoutManager(mContext );//設置布局管理器reportList.setLayoutManager(layoutManager);reportList.setAdapter(recycleAdapter);
