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[b]clearCheck()之前，如果RadioGroup已经设置过监听，执行就会报StackOveflowError错误。[/b][b]解决办法：[/b]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;
}
}
}
