您可以使用以下代码：

活动代码：

protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        for(int row=0; row < 5; row++) 
         {
            LinearLayout ll = new LinearLayout(this);
            ll.setOrientation(LinearLayout.HORIZONTAL);
            for(int i = 0; i < 2; i++) {
                RadioButton rdbtn = new RadioButton(this);
                rdbtn.setId((row * 2) + i);
                rdbtn.setText("test " + rdbtn.getId());
                ll.addView(rdbtn);
            }
            ((ViewGroup)findViewById(R.id.radiogroup)).addView(ll);
         }
    }

活动主.xml：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity" >

    <RadioGroup
        android:id="@+id/radiogroup"
        android:orientation="vertical"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true"/>

</RelativeLayout>
