1.xml中的布局：

这样就实现了多行布局，这只是我布局中的一部分，其中 android:textSize=”@dimen/RB_text_size”　为自己定义的字体大小．

2.activity中的使用以及处理：

public class SelectMoneyActivity extends BaseActivity { String strBtnSelected = "";　//记录选择的是哪个选项 private RadioGroup rg1, rg2, rg3, rg4; private RadioButton rb_1, rb_2, rb_3, rb_4, rb_5, rb_6, rb_7, rb_8, rb_9, rb_10; @Override protected void onCreate(Bundle savedInstanceState) {  super.onCreate(savedInstanceState);  setContentView(R.layout.activity_select_money);  initView(); } private void initView() {  rg1 = (RadioGroup) findViewById(R.id.radio1);  rg2 = (RadioGroup) findViewById(R.id.radio2);  rg3 = (RadioGroup) findViewById(R.id.radio3);  rg4 = (RadioGroup) findViewById(R.id.radio4);  rb_1 = (RadioButton) findViewById(R.id.rb_1);  rb_2 = (RadioButton) findViewById(R.id.rb_2);  rb_3 = (RadioButton) findViewById(R.id.rb_3);  rb_4 = (RadioButton) findViewById(R.id.rb_4);  rb_5 = (RadioButton) findViewById(R.id.rb_5);  rb_6 = (RadioButton) findViewById(R.id.rb_6);  rb_7 = (RadioButton) findViewById(R.id.rb_7);  rb_8 = (RadioButton) findViewById(R.id.rb_8);  rb_9 = (RadioButton) findViewById(R.id.rb_9);  rb_10 = (RadioButton) findViewById(R.id.rb_10);  btn_back = (Button) findViewById(R.id.btn_back);  btn_next = (Button) findViewById(R.id.btn_next);//创建监听器，为每个RadioButton注册监听  BtnSelected btnSelected1 = new BtnSelected("1");  BtnSelected btnSelected2 = new BtnSelected("2");  BtnSelected btnSelected3 = new BtnSelected("3");  BtnSelected btnSelected4 = new BtnSelected("4");  BtnSelected btnSelected5 = new BtnSelected("5");  BtnSelected btnSelected6 = new BtnSelected("6");  BtnSelected btnSelected7 = new BtnSelected("7");  BtnSelected btnSelected8 = new BtnSelected("8");  BtnSelected btnSelected9 = new BtnSelected("9");  BtnSelected btnSelected10 = new BtnSelected("10");  rb_1.setOnClickListener(btnSelected1);  rb_2.setOnClickListener(btnSelected2);  rb_3.setOnClickListener(btnSelected3);  rb_4.setOnClickListener(btnSelected4);  rb_5.setOnClickListener(btnSelected5);  rb_6.setOnClickListener(btnSelected6);  rb_7.setOnClickListener(btnSelected7);  rb_8.setOnClickListener(btnSelected8);  rb_9.setOnClickListener(btnSelected9);  rb_10.setOnClickListener(btnSelected10);//点击事件的监听器 public class BtnSelected implements View.OnClickListener {  private String btnId;  public BtnSelected(String str) {   btnId = str;  }  @Override  public void onClick(View v) {   strBtnSelected = btnId;　　//选择的某一项   isSelect = true;   //点击了第一行　，就把另外行的点击项清空   if (btnId.equals("1") || btnId.equals("2") || btnId.equals("3")) {    rg2.clearCheck();    rg3.clearCheck();    rg4.clearCheck();   } else if (btnId.equals("4") || btnId.equals("5") || btnId.equals("6")) {    rg1.clearCheck();    rg3.clearCheck();    rg4.clearCheck();   } else if (btnId.equals("7") || btnId.equals("8") || btnId.equals("9")) {    rg1.clearCheck();    rg2.clearCheck();    rg4.clearCheck();   } else {    rg1.clearCheck();    rg2.clearCheck();    rg3.clearCheck();   }  } }}
