Android Put Extra不会将Extra发送给其他活动

Question

I try to send some values to another activity.

recyclerView.addOnItemTouchListener(new RecyclerTouchListener(getApplicationContext(), recyclerView, new RecyclerTouchListener.ClickListener() {
            @Override
            public void onClick(View view, int position) {
             Intent intent  = new Intent(GroupsMain.this, AboutGroup.class);
                intent.putExtra("groupName", "Hello");
                startActivity(intent);
            }

            @Override
            public void onLongClick(View view, int position) {

            }
        }));

And so on AboutGroup activity I try to get extra. 1 way:

 Bundle extras = getIntent().getExtras();
        String name = extras.getString("groupName");

and second way:

 Intent intent = new Intent();
       String name = intent.getStringExtra("groupName");

But nothing works for me. On AboutGroup activity i get empty string. Please help me fix this problem.

Send:

Intent intent  = new Intent(MainActivity.this, Main2Activity.class);
intent.putExtra("groupName", "Hello Anna");
startActivity(intent);

get extra:

String name = getIntent().getStringExtra("groupName");
myTextview.setText(name);
