Java 两个放射组，每个放射组中只有一个选定的单选按钮

我的布局中有两个放射组。我希望在RadioGroup中一次只检查一个单选按钮。我试过很多方法，但没有一种能正常工作。现在我可以检查我组中的每个单选按钮

public class MainActivity extends ActionBarActivity implements View.OnClickListener, RadioGroup.OnCheckedChangeListener {

String x;
char y;

int c=1;

String num,n,type;
int d,b,o,h;
String dec,bin,hex,oct;

EditText number;
EditText result;

Button convert, clear;
RadioGroup rgFrom, rgTO;
int convertedResult;
int from=R.id.r10From;
int to=R.id.r2TO;

String stNumber; //Liczba przed przeliczeniem - string
int numbResult;  //Już int

String iterResult; //Liczba po przeliczeniu - string
int convResult;   //Już int

//int id = ((RadioGroup).findViewById( R.id.rgFrom )).getCheckedRadioButtonId();

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


}

 private void initialize() {
   number = (EditText) findViewById(R.id.etNumber);
   result = (EditText) findViewById(R.id.etResult);

    convert = (Button) findViewById(R.id.bCalculate);
    clear = (Button) findViewById(R.id.bReset);

    convert.setOnClickListener(this);
    clear.setOnClickListener(this);

    rgFrom = (RadioGroup) findViewById(R.id.rgFrom);
    rgTO = (RadioGroup) findViewById(R.id.rgTO);


    rgFrom.setOnCheckedChangeListener(this);
    rgTO.setOnCheckedChangeListener(this);
}


@Override
public void onClick(View view) {
   // from = (String)findViewById(R.id.rgFrom).getSelectedItem();
   // int id = ((RadioGroup)findViewById( R.id.rgFrom )).getCheckedRadioButtonId();
    //from = getFrom(id);

    switch (view.getId()){
        case R.id.r2From:
            from = rgFrom.getCheckedRadioButtonId();
            break;
        case  R.id.r8From:
            from = rgFrom.getCheckedRadioButtonId();
            break;
        case  R.id.r10From:
            from = rgFrom.getCheckedRadioButtonId();
            break;
        case  R.id.r16From:
            from = rgFrom.getCheckedRadioButtonId();
            break;
        case R.id.r2TO:
            to = rgTO.getCheckedRadioButtonId();
            break;
        case  R.id.r8TO:
            to = rgTO.getCheckedRadioButtonId();
            break;
        case  R.id.r10TO:
            to = rgTO.getCheckedRadioButtonId();
            break;
        case  R.id.r16TO:
            to = rgTO.getCheckedRadioButtonId();
            break;
        case  R.id.bCalculate:
            stNumber = number.getText().toString();
            //iterResult = result.getText().toString();
            //calculate();
            break;
        case  R.id.bReset:
            //reset();
            break;
    }
}
@Override
public void onCheckedChanged(RadioGroup rgFrom, int i) {
    switch (view.getId()){
        case R.id.r2From:
            from = rgFrom.getCheckedRadioButtonId();
            break;
        case  R.id.r8From:
            from = rgFrom.getCheckedRadioButtonId();
            break;
        case  R.id.r10From:
            from = rgFrom.getCheckedRadioButtonId();
            break;
        case  R.id.r16From:
            from = rgFrom.getCheckedRadioButtonId();
            break;
        case R.id.r2TO:
            to = rgTO.getCheckedRadioButtonId();
            break;
        case  R.id.r8TO:
            to = rgTO.getCheckedRadioButtonId();
            break;
        case  R.id.r10TO:
            to = rgTO.getCheckedRadioButtonId();
            break;
        case  R.id.r16TO:
            to = rgTO.getCheckedRadioButtonId();
            break;
    }
   }
}

从

半径组

相对值。所以代码看起来像：

    android:id="@+id/rgFrom"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginTop="10dp"

这将解决在同一组中选中多个按钮所面临的问题。然而，这将在UI中产生一个小问题。我想你希望一行有两个按钮，另外两个按钮在不同的行。据我所知，您必须为此实现自己的自定义布局。查看详细信息。检查一下。希望能有点帮助。
也许这会有帮助？两个放射组都包含一个RelativeLayout（相同错误的两倍）。。。为什么？请尽快移除它们。谢谢，它很有效。但是我怎么才能创造出和我的亲戚一样的东西呢？
