I have a recycle demo,but when I running the demo,is always show the error message"Recycleview RecyclerView: No adapter attached; skipping layout"
This is my main Activity class
public class MainActivity extends BaseActivity{
// private ListView mListView;
private ArrayList<Note> noteList;
private RecycleViewNoteListAdatper noteListAdapter;
private SwipeRefreshLayout mSwipeRefreshLayout;
private DrawerLayout drawerLayout;
private View drawerView;

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
initView();
initData();
initListener();
// colorChange();
if (android.os.Build.VERSION.SDK_INT >= 21) {
Window window = getWindow();
// 很明显，这两货是新API才有的。
// window.setStatusBarColor(colorBurn(R.color.colorPrimary));

this, drawerLayout, mToolbar, R.string.open_string,

drawerLayout.setDrawerListener(actionBarDrawerToggle);

This is my RecyclerViewAdapter Code
public class RecycleViewNoteListAdatper extends RecyclerView.Adapter<RecyclerView.ViewHolder>{
Context mContext;
private LayoutInflater layoutInflater;
private ArrayList<Note> list;
public RecycleViewNoteListAdatper(Context context,ArrayList<Note> note) {
this.mContext=context;
this.list=note;
layoutInflater = LayoutInflater.from(context);
}
@Override
public ViewHolder onCreateViewHolder(ViewGroup paramViewGroup, int paramInt) {
return new RecyclerViewHolder(layoutInflater.inflate(R.layout.item_notelist_2, paramViewGroup),this,mContext) ;
}
@Override
public void onBindViewHolder(ViewHolder paramVH, int paramInt) {
if(!ListUtils.isEmpty(list)){
Note note = list.get(paramInt);
((RecyclerViewHolder)paramVH).tv_introduce.setText(note.getNoteName());
}
}
@Override
public int getItemCount() {
if(!ListUtils.isEmpty(list)){
return list.size();
}
return 0;
}
public static class RecyclerViewHolder extends RecyclerView.ViewHolder implements OnClickListener{
RecyclerView.Adapter<ViewHolder> mAdapter;
Context mContext;
RelativeLayout ll_container;
LinearLayout ll_action;
Button action1,action2,action3;
TextView tv_introduce;
public RecyclerViewHolder(View view,RecyclerView.Adapter<ViewHolder> adapter,Context context) {
super(view);
this.mAdapter=adapter;
this.mContext=context;
tv_introduce = (TextView) view.findViewById(R.id.item_introduce);
action1=(Button) view.findViewById(R.id.button1);
action2=(Button) view.findViewById(R.id.button2);
action3=(Button) view.findViewById(R.id.button3);
ll_container=(RelativeLayout) view.findViewById(R.id.ll_container);
ll_action=(LinearLayout) view.findViewById(R.id.ll_action);
action1.setOnClickListener(this);
action2.setOnClickListener(this);
action3.setOnClickListener(this);
ll_container.setOnClickListener(this);
}
@Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.button1:
ToastUtils.showToast(mContext, "onClick1");
break;
case R.id.button2:
ToastUtils.showToast(mContext, "onClick2");
break;
case R.id.button3:
ToastUtils.showToast(mContext, "onClick3");
break;
case R.id.ll_container:
Intent intent=new Intent(mContext,SimpleNoteEditActivity.class);

break;

}
}
}
