Android RadioGroup多行显示，解决单选问题

效果如下：

非常简单！RadioGroup多行显示其实就是两个RadioGroup进行切换，使用RadioGroup的clearCheck()方法进行操作。

但是在使用clearCheck()之前，如果RadioGroup已经设置过监听，执行就会报StackOveflowError错误。

解决办法：

先setOnCheckedChangeListener（null）再调用clearCheck()然后重新setOnCheckedChangeListener（checkedListener）。

1、布局如下：

                  <RadioGroup                        android:id="@+id/rg_manhole_state_one"                        android:layout_width="wrap_content"                        android:layout_height="wrap_content"                        android:layout_marginTop="5dp"                        android:layout_toRightOf="@id/tv_manhole_state"                        android:orientation="horizontal"                        android:paddingTop="@dimen/padding_5">                        <RadioButton                            android:id="@+id/rb_intact"                            android:layout_width="wrap_content"                            android:layout_height="wrap_content"                            android:button="@null"                            android:drawableLeft="@drawable/bg_radiobutten"                            android:drawablePadding="@dimen/padding_10"                            android:text="@string/intact"                            android:textColor="@color/white"                            android:textSize="@dimen/small_size" />                        <RadioButton                            android:id="@+id/rb_lose"                            android:layout_width="wrap_content"                            android:layout_height="wrap_content"                            android:layout_marginLeft="30dp"                            android:button="@null"                            android:drawableLeft="@drawable/bg_radiobutten"                            android:drawablePadding="@dimen/padding_10"                            android:text="@string/lose"                            android:textColor="@color/white"                            android:textSize="@dimen/small_size" />                        <RadioButton                            android:id="@+id/rb_sunken"                            android:layout_width="wrap_content"                            android:layout_height="wrap_content"                            android:layout_marginLeft="30dp"                            android:button="@null"                            android:drawableLeft="@drawable/bg_radiobutten"                            android:drawablePadding="@dimen/padding_10"                            android:text="@string/sunken"                            android:textColor="@color/white"                            android:textSize="@dimen/small_size" />                    </RadioGroup>                 <RadioGroup                    android:id="@+id/rg_manhole_state_two"                    android:layout_width="wrap_content"                    android:layout_height="wrap_content"                    android:layout_marginLeft="@dimen/padding_100"                    android:layout_marginTop="5dp"                    android:orientation="horizontal"                    android:paddingTop="@dimen/padding_5">                    <RadioButton                        android:id="@+id/rb_occupation"                        android:layout_width="wrap_content"                        android:layout_height="wrap_content"                        android:button="@null"                        android:drawableLeft="@drawable/bg_radiobutten"                        android:drawablePadding="@dimen/padding_10"                        android:text="@string/occupation"                        android:textColor="@color/white"                        android:textSize="@dimen/small_size" />                    <RadioButton                        android:id="@+id/rb_damage"                        android:layout_width="wrap_content"                        android:layout_height="wrap_content"                        android:layout_marginLeft="30dp"                        android:button="@null"                        android:drawableLeft="@drawable/bg_radiobutten"                        android:drawablePadding="@dimen/padding_10"                        android:text="@string/damage"                        android:textColor="@color/white"                        android:textSize="@dimen/small_size" />                    <RadioButton                        android:id="@+id/rb_heave"                        android:layout_width="wrap_content"                        android:layout_height="wrap_content"                        android:layout_marginLeft="30dp"                        android:button="@null"                        android:drawableLeft="@drawable/bg_radiobutten"                        android:drawablePadding="@dimen/padding_10"                        android:text="@string/heave"                        android:textColor="@color/white"                        android:textSize="@dimen/small_size" />                </RadioGroup>

2、具体操作如下：

声明控件：

    @InjectView(R.id.rg_manhole_state_one)    RadioGroup rgManholeStateOne;    @InjectView(R.id.rg_manhole_state_two)    RadioGroup rgManholeStateTwo;

设置监听：

       rgManholeStateOne.setOnCheckedChangeListener(new OnMyManholeStateOneCheckedChangeListener());        rgManholeStateTwo.setOnCheckedChangeListener(new OnMyManholeStateTwoCheckedChangeListener());

实现单选

    private class OnMyManholeStateOneCheckedChangeListener implements RadioGroup.OnCheckedChangeListener {        @Override        public void onCheckedChanged(RadioGroup radioGroup, int position) {            switch (position) {                case R.id.rb_intact:                    if (rbIntact.isChecked())                        rgManholeStateTwo.clearCheck();                    break;                case R.id.rb_lose:                    if (rbLose.isChecked())                        rgManholeStateTwo.clearCheck();                    break;                case R.id.rb_sunken:                    if (rbSunken.isChecked())                        rgManholeStateTwo.clearCheck();                    break;            }        }    }    private class OnMyManholeStateTwoCheckedChangeListener implements RadioGroup.OnCheckedChangeListener {        @Override        public void onCheckedChanged(RadioGroup radioGroup, int position) {            switch (position) {                case R.id.rb_occupation:                    if (rbOccupation.isChecked())                        rgManholeStateOne.clearCheck();                    break;                case R.id.rb_damage:                    if (rbDamage.isChecked())                        rgManholeStateOne.clearCheck();                    break;                case R.id.rb_heave:                    if (rbHeave.isChecked())                        rgManholeStateOne.clearCheck();                    break;            }        }    }
