Android RadioButtons僅在仿真器上行爲不端

Question

我在xml中擁有RadioGroup。我用代碼中的RadioButton填充它。 問題是，在模擬器RadioButtons不行爲w.r.t RadioGroup。我可以一次選擇所有的單選按鈕。但是，一切似乎都能在真實設備上正常工作。

下面是截圖和代碼的所有文件：

來源爲MainActivity.java

public class MainActivity extends Activity { 
/** Called when the activity is first created. */ 
private RadioGroup rg; 

@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.main); 

    LayoutInflater inflater = LayoutInflater.from(getBaseContext()); 
    rg = (RadioGroup)findViewById(R.id.rg); 

    for (int i = 0; i < 5; i++) { 
     inflater.inflate(R.layout.myradio, rg,true); 
    } 

} 

}

main.xml中

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    android:orientation="vertical" 
    android:id="@+id/llContainer" 
    tools:context=".MainActivity" > 


<RadioGroup 
    android:id="@+id/rg" 
    android:background="#0000ff" 
    android:orientation="vertical" 
    android:layout_height="wrap_content" 
    android:layout_width="fill_parent"> 

</RadioGroup> 

myradio.xml

<?xml version="1.0" encoding="utf-8"?> 

<RadioButton xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_gravity="center" 
    android:text="RadioButton" />

它會像這樣

public class example extends Activity { 
    /** Called when the activity is first created. */ 
    private RadioGroup rgroup; 
    RadioButton rb; 


    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.example); 


     rgroup = (RadioGroup)findViewById(R.id.rg); 
     final RadioButton[] rb = new RadioButton[5]; 
     for (int i = 0; i < 5; i++) { 
      rb[i]=new RadioButton(this); 
      rb[i].setText("rdo"+i); 
      rb[i].setId(i); 
      rgroup.addView(rb[i]); 


     } 

    } 

    }
