on_user=findViewById(R.id.on_user);
        on_password=findViewById(R.id.on_password);
        on_juese=findViewById(R.id.on_juese);

        on_juese.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(RadioGroup radioGroup, int i) {
                if(i==R.id.student) juese="student";
                if(i==R.id.techer)  juese="teacehr";
            }
        });

        btn1=findViewById(R.id.haveoning);
        btn1.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Intent intent=new Intent(MainActivity.this,Zhuce.class);
                startActivity(intent);

            }
        });

        btn2=findViewById(R.id.oning);
        btn2.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {

                String shuow=on_user.getText().toString()+on_password.getText().toString()+juese;
                Toast.makeText(MainActivity.this,shuow,Toast.LENGTH_LONG).show();
            }
        });


    }
