先给出RadioButton的布局

< com.kuibu.jucai.widget.MyRadioGroup
android:id="@+id/myRadioGroup"
android:layout_width="match_parent"
android:layout_height="wrap_content">

< LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">

< RadioButton

< /LinearLayout>

< LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">

< RadioButton
android:id="@+id/rb_200"
android:layout_width="match_parent"
android:layout_height="35dp"
android:layout_marginLeft="@dimen/space_10"

android:text="1000￥"
android:textColor="@drawable/fg_order_text_selector" />
< /LinearLayout>
< /com.kuibu.jucai.widget.MyRadioGroup>

这里用到了一个自定义控件,如下

public class MyRadioGroup extends RadioGroup {

//对外暴漏
private OnCheckedChangeListener mOnCheckedChangeListener;

public MyRadioGroup(Context context) {
super(context);
}

public MyRadioGroup(Context context, AttributeSet attrs) {
super(context, attrs);
}

public void setOnCheckedChangeListener(OnCheckedChangeListener listener) {
mOnCheckedChangeListener = listener;
}

@Override
public void addView(final View child, int index, ViewGroup.LayoutParams params) {
if (child instanceof LinearLayout) {
int childCount = ((LinearLayout) child).getChildCount();
for (int i = 0; i < childCount; i++) {
View view = ((LinearLayout) child).getChildAt(i);
if (view instanceof RadioButton) {
final RadioButton button = (RadioButton) view;
((RadioButton) button).setOnTouchListener(new OnTouchListener() {

@Override
public boolean onTouch(View v, MotionEvent event) {
((RadioButton) button).setChecked(true);
checkRadioButton((RadioButton) button);
if (mOnCheckedChangeListener != null) {
mOnCheckedChangeListener.onCheckedChanged(MyRadioGroup.this, button.getId());
}
return true;
}
});
}
}
}

super.addView(child, index, params);
}

private void checkRadioButton(RadioButton radioButton) {
View child;
int radioCount = getChildCount();
for (int i = 0; i < radioCount; i++) {
child = getChildAt(i);
if (child instanceof RadioButton) {
if (child == radioButton) {
// do nothing
} else {
((RadioButton) child).setChecked(false);
}
} else if (child instanceof LinearLayout) {
int childCount = ((LinearLayout) child).getChildCount();
for (int j = 0; j < childCount; j++) {
View view = ((LinearLayout) child).getChildAt(j);
if (view instanceof RadioButton) {
final RadioButton button = (RadioButton) view;
if (button == radioButton) {
// do nothing
} else {
((RadioButton) button).setChecked(false);
}
}
}
}
}
}
}

网络不好,无法直接插入代码,只能这样拷贝了.
