本文實例講述了Android編程實現變化的雙重選擇框功能。分享給大家供大家參考，具體如下：

原理：定義四個RadioGroup，通過第一個RadioGroup的選擇來控制其余幾個radiogroup的顯隱

布局：

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"  android:layout_width="match_parent"  android:layout_height="match_parent"  android:orientation="vertical"  android:padding="20dp">  <TextView    android:layout_width="match_parent"    android:layout_height="wrap_content"    android:text="請選擇圖層"    android:textColor="@color/green"    android:textSize="@dimen/text"/>  <RadioGroup    android:layout_width="match_parent"    android:layout_height="wrap_content"    android:id="@+id/radiogroup1">    <RadioButton      android:layout_width="match_parent"      android:layout_height="wrap_content"      android:text="永順鎮規劃圖"      android:id="@+id/radi1"      android:checked="true"      />    <RadioButton      android:layout_width="match_parent"      android:layout_height="wrap_content"      android:text="永順鎮權屬"      android:id="@+id/radi2"/>    <RadioButton      android:layout_width="match_parent"      android:layout_height="wrap_content"      android:text="永順鎮現狀"      android:id="@+id/radi3"/>  </RadioGroup>  <TextView    android:layout_width="match_parent"    android:layout_height="wrap_content"    android:text="選擇查詢字段"    android:textColor="@color/green"    android:textSize="@dimen/text"/>  <RadioGroup    android:layout_width="match_parent"    android:layout_height="wrap_content"    android:id="@+id/radiogroup2">    <RadioButton      android:layout_width="match_parent"      android:layout_height="wrap_content"      android:text="地塊編號"      android:id="@+id/a1"      android:checked="true"/>    <RadioButton      android:layout_width="match_parent"      android:layout_height="wrap_content"      android:text="用地性質"      android:id="@+id/a2"/>    <RadioButton      android:layout_width="match_parent"      android:layout_height="wrap_content"      android:text="用地分類"      android:id="@+id/a3"/>  </RadioGroup>  <RadioGroup    android:layout_width="match_parent"    android:layout_height="wrap_content"    android:id="@+id/radiogroup3"    android:visibility="gone">    <RadioButton      android:layout_width="match_parent"      android:layout_height="wrap_content"      android:text="權屬性質"      android:id="@+id/b1"      android:checked="true"/>  </RadioGroup>  <RadioGroup    android:layout_width="match_parent"    android:layout_height="wrap_content"    android:id="@+id/radiogroup4"    android:visibility="gone">    <RadioButton      android:layout_width="match_parent"      android:layout_height="wrap_content"      android:text="用地類別"      android:id="@+id/c1"      android:checked="true"/>    <RadioButton      android:layout_width="match_parent"      android:layout_height="wrap_content"      android:text="地類號"      android:id="@+id/c2"/>    <RadioButton      android:layout_width="match_parent"      android:layout_height="wrap_content"      android:text="圖斑號"      android:id="@+id/c3"/>  </RadioGroup>  <AutoCompleteTextView    android:layout_width="match_parent"    android:layout_height="wrap_content"    android:text="請輸入查詢內容"    android:id="@+id/autoCompleteTextView" /></LinearLayout>

java代碼：

LayoutInflater layoutInflater=LayoutInflater.from(MainPlan.this);View self=layoutInflater.inflate(R.layout.thiswindow, null);final RadioGroup radioGroup1 = (RadioGroup) self.findViewById(R.id.radiogroup1);final RadioGroup radioGroup2 = (RadioGroup) self.findViewById(R.id.radiogroup2);final RadioGroup radioGroup3 = (RadioGroup) self.findViewById(R.id.radiogroup3);final RadioGroup radioGroup4 = (RadioGroup) self.findViewById(R.id.radiogroup4);radioGroup1.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {  @Override  public void onCheckedChanged(RadioGroup group, int checkedId) {   switch (checkedId){     case R.id.radi1:       radioGroup2.setVisibility(View.VISIBLE);       radioGroup3.setVisibility(View.GONE);       radioGroup4.setVisibility(View.GONE);       break;     case R.id.radi2:       radioGroup2.setVisibility(View.GONE);       radioGroup3.setVisibility(View.VISIBLE);       radioGroup4.setVisibility(View.GONE);break;     case R.id.radi3:       radioGroup2.setVisibility(View.GONE);       radioGroup3.setVisibility(View.GONE);       radioGroup4.setVisibility(View.VISIBLE);break;     default:break;   }  }});
