CustomRecyclerAdapter第83行
viewHolder.textView.setText(getTitle(position));
CustomRecyclerAdapter第26行
private final int orientation;
你们有什么想法我能得到这个吗？
查看持有人
public static class ViewHolder extends RecyclerView.ViewHolder {
public ImageView imageView;
public TextView time;
public TextView textView;
public TextView temperature;
public ViewHolder(View row){
super(row);
imageView = (ImageView) row.findViewById(R.id.imageView);
time = (TextView) row.findViewById(R.id.time);
textView = (TextView) row.findViewById(R.id.textView);
temperature = (TextView) row.findViewById(R.id.temperature);
}
