尝试在LinearLayout中使用文本视图和放射组时出错

<LinearLayout

    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Select an option:"
        android:textSize="18sp"/>

    <RadioGroup
        android:id="@+id/radioGroup"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:orientation="horizontal">

        <RadioButton
            android:id="@+id/radioButton1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"

        <RadioButton

            android:layout_height="wrap_content"
            android:text="Option 2"/>
    </RadioGroup>
</LinearLayout>

public class MainActivity extends AppCompatActivity {
    private RadioGroup radioGroup;

    @Override
