Answer 1

向holder.text_number添加一个OnclickListener:

String message = "";  
holder.text_number.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                message = textview.getText().toString();
                Toast.makeText(getActivity(), "Message : " + message, Toast.LENGTH_LONG).show();

            }
        });

现在用message字符串做任何你想做的事情。
