Coding Multiple RadioGroups

Question

I'm creating a basic app in Android Studio:

There are 3 categories with a radio group for each category.

The user selects one button from each category then hits "Choose".

A Textview should show a message, e.g. "You chose Chinese, Level 1, Guess the City".

I've worked out how to say "You chose Chinese" but can't figure out how to add the rest using if conditions. Any ideas?

<TextView android:id="@+id/text" />
<RadioGroup android:id="@+id/radio1">
    <RadioButton id="@+id/chinese"
        android:text="@string/chinese" />
    <RadioButton android:id="@+id/indian"
        android:text="@string/indian" />
    <RadioButton android:id="@+id/russian"
        android:text="@string/russian" />
</RadioGroup>
<RadioGroup android:id="@+id/radio2">
    <RadioButton android:id="@+id/difficulty1"
        android:text="@string/starter" />
    <RadioButton android:id="@+id/difficulty2"
            android:text="@string/medium" />
    <RadioButton android:id="@+id/difficulty3"
            android:text="@string/expert" />
</RadioGroup>
<RadioGroup android:id="@+id/radio3">
    <RadioButton android:id="@+id/challenge1"
            android:text="@string/buildingbricks" />
    <RadioButton android:id="@+id/challenge2"
            android:text="@string/callcentre" />
    <RadioButton android:id="@+id/challenge3"
            android:text="@string/city" />
</RadioGroup>

    public String string_first_radiogroup, 

    @Override

        radioGroup1 = (RadioGroup) findViewById(R.id.radio1);


        radioGroup1.setOnCheckedChangeListener(new OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(RadioGroup group, int checkedId) {
                if(checkedId == R.id.chinese) {
                    string_first_radiogroup="Chinese";
                } else if(checkedId == R.id.indian) {
                    string_first_radiogroup="Indian"; 
                } else {
                    string_first_radiogroup="Russian";
                }
            }
        });

        chinese = (RadioButton) findViewById(R.id.chinese);
        indian = (RadioButton) findViewById(R.id.indian);
        russian = (RadioButton) findViewById(R.id.russian);
        textView = (TextView) findViewById(R.id.text);


        button = (Button)findViewById(R.id.choose);
        button.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                textView.setText("You chose " + string_first_radiogroup + " option");
            }
        });
    }
}

Answer 1

Try below code:

button.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                textView.setText("You chose " + ((RadioButton)findViewById(radioGroup1.getCheckedRadioButtonId())).getText() + " option");
            }
        });
