android 多行 RadioButton的使用

最近项目用到了多行RadioButton,随记录下.

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            android:id="@+id/rb_50"            android:layout_width="match_parent"            android:layout_height="35dp"            android:layout_marginLeft="@dimen/space_10"            android:layout_weight="1"            android:background="@drawable/poundage_selector"            android:button="@null"            android:gravity="center"            android:paddingBottom="@dimen/space_10"            android:paddingLeft="@dimen/space_20"            android:paddingRight="@dimen/space_20"            android:paddingTop="@dimen/space_10"            android:text="50￥"            android:textColor="@drawable/fg_order_text_selector" />

        <RadioButton            android:id="@+id/rb_100"            android:layout_width="match_parent"            android:layout_height="35dp"            android:layout_marginLeft="@dimen/space_10"            android:layout_weight="1"            android:background="@drawable/poundage_selector"            android:button="@null"            android:gravity="center"            android:paddingBottom="@dimen/space_10"            android:paddingLeft="@dimen/space_20"            android:paddingRight="@dimen/space_20"            android:paddingTop="@dimen/space_10"            android:text="100￥"            android:textColor="@drawable/fg_order_text_selector" />

        <RadioButton            android:id="@+id/rb_150"            android:layout_width="match_parent"            android:layout_height="35dp"            android:layout_marginLeft="@dimen/space_10"            android:layout_marginRight="@dimen/space_10"            android:layout_weight="1"            android:background="@drawable/poundage_selector"            android:button="@null"            android:gravity="center"            android:paddingBottom="@dimen/space_10"            android:paddingLeft="@dimen/space_30"            android:paddingRight="@dimen/space_30"            android:paddingTop="@dimen/space_10"            android:text="150￥"            android:textColor="@drawable/fg_order_text_selector" />

    </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:layout_marginTop="@dimen/space_10"            android:layout_weight="1"            android:background="@drawable/poundage_selector"            android:button="@null"            android:gravity="center"            android:paddingBottom="@dimen/space_10"            android:paddingLeft="@dimen/space_20"            android:paddingRight="@dimen/space_20"            android:paddingTop="@dimen/space_10"            android:text="200￥"            android:textColor="@drawable/fg_order_text_selector" />

        <RadioButton            android:id="@+id/rb_500"            android:layout_width="match_parent"            android:layout_height="35dp"            android:layout_marginLeft="@dimen/space_10"            android:layout_marginTop="@dimen/space_10"            android:layout_toRightOf="@+id/rb_200"            android:layout_weight="1"            android:background="@drawable/poundage_selector"            android:button="@null"            android:gravity="center"            android:paddingBottom="@dimen/space_10"            android:paddingLeft="@dimen/space_20"            android:paddingRight="@dimen/space_20"            android:paddingTop="@dimen/space_10"            android:text="500￥"            android:textColor="@drawable/fg_order_text_selector" />

        <RadioButton            android:id="@+id/rb_1000"            android:layout_width="match_parent"            android:layout_height="35dp"            android:layout_marginLeft="@dimen/space_10"            android:layout_marginRight="@dimen/space_10"            android:layout_marginTop="@dimen/space_10"            android:layout_toRightOf="@+id/rb_500"            android:layout_weight="1"            android:background="@drawable/poundage_selector"            android:button="@null"            android:gravity="center"            android:paddingBottom="@dimen/space_10"            android:paddingLeft="@dimen/space_20"            android:paddingRight="@dimen/space_20"            android:paddingTop="@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.
