setText textview with radiobutton

[nishika]

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    textView = (TextView)  findViewById(R.id.textView);
    radioGroup= (RadioGroup) findViewById(R.id.radiogroup);
    radioGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener(){
        @Override
        public void onCheckedChanged(RadioGroup group, int checkedId) {
            // checkedId is the RadioButton selected
            RadioButton radioButton_250=(RadioButton)findViewById(checkedId);
            textView.setText(radioButton_250.getText());
            RadioButton radioButton_500=(RadioButton)findViewById(checkedId);
            textView.setText(radioButton_500.setText("70"));

        }
    });
}

The first button that pulls the text is fine, and here's the second. textView.setText(radioButton_500.setText("70")); Can't let you fix this fast?

Stroke

textView.setText(radioButton_500.setText("70));

Not to be compiled, as the setText() method requires String as an argument and the result of the challenge. radioButton_500.setText("70") returns void♪

If you need to change the text to the radioButton and then appoint it somewhere, do it in turn:

radioButton_500.setText("70");
textView.setText(radioButton_500.getText());

For changing the radioButtom test in RadioGroup, you have to do something like this:

radioGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener(){
    @Override
    public void onCheckedChanged(RadioGroup group, int checkedId) {
        // checkedId is the RadioButton selected
        //RadioButton radioButton = (RadioButton) group.findViewById(checkedId);
        //textView.setText(radioButton.getText());
        switch(checkedId)
        {
            case R.id.someID:
                //тут нужный текст установите
                break;
            case R.id.anotherID:
                //тут нужный текст установите
                break;
        }
    }
});
