I think many people, try to do this demo. But this demo is not good, because some things no show.
like:

RecyclerView .xml to a layout:…….only little, but ok, this not import.

MyAdapter .xml no layout: this is bad. Get error in here.

so, follow this do is better

Gorcyn  is good guy~~ ^ ^

But what different with android demo (fxxxxxxxxxxxxxx)

android:

  • public ViewHolder(TextView v) {
  • mTextView = v;

good guy:

  • public ViewHolder(View v) {
  • mTextView = v.findViewById(R.id.textView));

so Now I think you understand what happen, if you lean java.

Why android developer not put full demo, than everybody get right demo. I search this issue, wast 3 hours. And on internet many people get this problem. Really miss Delphi~~

write java let me feel back ten years ago. that time write can use jbuilder 2. But now ………..

powerbuilder is good for demo, too.
