<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

                android:layout_height="wrap_content"
                android:textSize="22sp"

                android:checked="true"
                android:text="大笑"/>

            <RadioButton

                android:text="迷人"/>
        </RadioGroup>
    </RadioGroup>

</LinearLayout>

接下来是activity的部分关键代码

button1.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
            
          @Override
            public void onCheckedChanged(RadioGroup group, int checkedId) {
                if (rbthehua.isChecked()) {
                    ivpicture.setImageResource(R.drawable.hehua);
                    button2.clearCheck();
                }
                if (rbtmudanhua.isChecked()) {
                    ivpicture.setImageResource(R.drawable.mudanhua);
                    button2.clearCheck();
                }
                if (rbtmeihua.isChecked()) {
                    ivpicture.setImageResource(R.drawable.meihua);
                    button2.clearCheck();
                }

            }
        });
        rg2.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
            
            @Override
            public void onCheckedChanged(RadioGroup group, int checkedId) {
                if (rbtrose.isChecked()) {
                    ivpicture.setImageResource(R.drawable.rose);
                    button1.clearCheck();
                }
                if (rbtmantianx.isChecked()) {
                    ivpicture.setImageResource(R.drawable.mantianx);
                    button1.clearCheck();
                }
                if (rbtyinghua.isChecked()) {
                    ivpicture.setImageResource(R.drawable.yinghua);
                    button1.clearCheck();
                }
            }

        });
    }
}
