how to place different conditions of performance onClick in radibuttons

[elysha]

There's a display:

And code:

public class MainActivity extends AppCompatActivity  implements View.OnClickListener{
    ImageView plus;
    ImageView minus;
    TextView tvResult;
    TextView cena;
    TextView cena_53_skritaya;
    TextView cena_73_skritaya;
    RadioGroup radioGroup_cena;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    plus = (ImageView) findViewById(R.id.plus);
    plus.setOnClickListener(this);
    minus= (ImageView) findViewById(R.id.minus);
    minus.setOnClickListener(this);
    tvResult = (TextView) findViewById(R.id.tvResult);
    cena = (TextView) findViewById(R.id.cena);
    cena_53_skritaya = (TextView) findViewById(R.id.textView_53);
    cena_73_skritaya = (TextView) findViewById(R.id.textView_73);
    radioGroup_cena = (RadioGroup) findViewById(R.id.radioGroup_cena);
    radioGroup_cena.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {

        @Override
        public void onCheckedChanged(RadioGroup group, int checkedId) {

            switch (checkedId) {
                case R.id.radioButton_250:
                    cena.setText("53");
                    break;

                case R.id.radioButton_500:
                    cena.setText("73");
                    break;
            }
        }
    });
}

@Override
 public void onClick(View v) {
    int parse_kolichestvo;
    int parse_cena_53;
    int num2 = 1;
    int result = 0;
    int resultcena=0;

    // читаем TextView и заполняем переменные числами
    parse_kolichestvo = Integer.parseInt(tvResult.getText().toString());
    parse_cena_53 = Integer.parseInt(cena_53_skritaya.getText().toString());
    switch (v.getId()) {
        case R.id.plus:
            result = parse_kolichestvo + num2;
            resultcena= result*parse_cena_53;
    }
    switch (v.getId()) {
        case R.id.minus:
            result = parse_kolichestvo - num2;
            if (parse_kolichestvo==1){
                return;
            }
            resultcena= result*parse_cena_53;
    }
    // формируем строку вывода
    tvResult.setText( String.valueOf(result) );
    cena.setText( String.valueOf(resultcena) );

}

}

As you can see in OnClick, the program passes the first number (53) and multiplies the number, in this case, 1 plus and minus (Image View) changes the quantity and takes a step. Now, the question of how to move this cycle to the

 switch (checkedId) {

case R.id.radioButton_250:

cena.setText("53");

break;

And then you'll have another cycle of work,

 case R.id.radioButton_500:

cena.setText("73");

break;

But it's 73, not 53.
I tried myself, but there are problems with the ImageView symbol for each of the cycles.

It's kind of like... I haven't seen a single cycle in the code that you want to move... But looking at your scroll case, the design of the building. onClick I understand that you don't know what you're doing. But we were all once like this, so I'll try.

In fact, from what I tried to figure out from your rebus, I'm not sure you're doing the right thing. onClick Method of using field data that are filled by cell selection tools CheckGroupNot from Integer.parseInt(cena_53_skritaya.getText().toString())♪ Then you won't care what element is chosen and the logic will work exactly for the price you've set in. CheckGroup♪
