错误(3)

 1、Attempt to invoke virtual method 'void android.widget.ListView.setAdapter(android.widget.ListAdapter)' on a null object reference

未findView

 listView = findViewById(R.id.listview);

  listView.setAdapter(myAdapter);

 

2、String resource ID #0x1

setText中传了其他类型,只能传String

 String most = String.valueOf(clock.getMost_day());
        viewHolder.t_username.setText( clock.getUsername());
        viewHolder.t_mostDay.setText(most);
