如何以编程方式将文本设置为RadioGroup内的RadioButton？

Question

我有一个RadioGroup内部,我有一些RadioButton.

我想以RadioButton编程方式在s 上设置一些文本.我使用了以下代码,因为我无法访问使用Java RadioButton的内部RadioGroup代码.

如何在RadioButton内部设置文本RadioGroup？

XML布局:

<RadioGroup android:layout_width="fill_parent"
    android:layout_marginLeft="20dip"
    android:layout_height="wrap_content"
    android:orientation="vertical"
    android:id="@+id/QueGroup1">

    <RadioButton android:checked="false"
        android:button="@drawable/green"
        android:layout_height="wrap_content"
        android:layout_width="fill_parent"
        android:textColor="#000"
        android:text="Yes"
        android:id="@+id/rbtnYes"
        android:visibility="gone" />

    <RadioButton android:checked="false"
        android:button="@drawable/red"
        android:textColor="#000"
        android:text="No"
        android:layout_height="wrap_content"
        android:layout_width="fill_parent" 
        android:id="@+id/rbtnNo"
        android:visibility="gone" />

    <RadioButton android:checked="false"
        android:button="@drawable/red"
        android:textColor="#000"
        android:text="Dont Know"
        android:layout_height="wrap_content"
        android:layout_width="fill_parent"
        android:id="@+id/rbtnDontKnow"
        android:visibility="gone" />
</RadioGroup>

Java代码:

private void fnRadioTextSet(String strval) {
    rbtnYes = (RadioButton)findViewById(R.id.rbtnYes);
    rbtnNo = (RadioButton)findViewById(R.id.rbtnNo);
    rbtnDontKnow = (RadioButton)findViewById(R.id.rbtnDontKnow);
    RadioGroup rbtnGrp = (RadioGroup)findViewById(R.id.QueGroup1);
    String[] strArrtext = strval.split(",");
    for (int intcount = 0; intcount < strArrtext.length; intcount++) {
        rbtnGrp.getChildAt(intcount).settext("test");
    }

    //int i = rbtnGrp.getChildCount();
    //Toast.makeText(getApplication(), rbtnGrp.getChildCount(),
    //      Toast.LENGTH_LONG).show();
    /*String[] strtext = strval.split(",");
    if (strtext.length > 0) {

    }*/
}

private void fnRadioTextSet(String strval) {
    RadioGroup rbtnGrp = (RadioGroup)findViewById(R.id.QueGroup1);
    String[] strArrtext = strval.split(",");
    for (int i = 0; i < rbtnGrp.getChildCount(); i++) {
        ((RadioButton) rbtnGrp.getChildAt(i)).setText(strArrtext[i]);
    }
}
