原理:定义四个RadioGroup,通过第一个RadioGroup的选择来控制其余几个radiogroup的显隐
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="请选择图层" 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="永顺镇规划图" android:id="@+id/radi1" android:checked="true" /> <RadioButton android:layout_width="match_parent" android:layout_height="wrap_content" android:text="永顺镇权属" android:id="@+id/radi2"/> <RadioButton android:layout_width="match_parent" android:layout_height="wrap_content" android:text="永顺镇现状" android:id="@+id/radi3"/> </RadioGroup> <TextView android:layout_width="match_parent" android:layout_height="wrap_content" android:text="选择查询字段" 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="地块编号" android:id="@+id/a1" android:checked="true"/> <RadioButton android:layout_width="match_parent" android:layout_height="wrap_content" android:text="用地性质" android:id="@+id/a2"/> <RadioButton android:layout_width="match_parent" android:layout_height="wrap_content" android:text="用地分类" 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="权属性质" 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="用地类别" android:id="@+id/c1" android:checked="true"/> <RadioButton android:layout_width="match_parent" android:layout_height="wrap_content" android:text="地类号" android:id="@+id/c2"/> <RadioButton android:layout_width="match_parent" android:layout_height="wrap_content" android:text="图斑号" android:id="@+id/c3"/> </RadioGroup> <AutoCompleteTextView android:layout_width="match_parent" android:layout_height="wrap_content" android:text="请输入查询内容" android:id="@+id/autoCompleteTextView" /></LinearLayout>
java代码:
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; } }});
