本文实例讲述了Android编程实现变化的双重选择框功能。分享给大家供大家参考,具体如下:
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;
}
}
});
