效果显示：
1、页面xml代码（项目的代码，直接复制会有错，自己修改一下就好）
代码语言：javascript复制<TextView
android:id="@ id/consultation_tv_section"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_above="@ id/consultation_et_doctor"
android:layout_alignLeft="@ id/consultation_tv_phone"
android:layout_alignStart="@ id/consultation_tv_phone"
android:layout_marginBottom="8dp"
android:text="挂号科室："
android:textColor="@color/black"
android:textSize="18sp"
android:textStyle="bold" /
<Spinner
android:id="@ id/consultation_et_section"
android:layout_width="260dp"
android:layout_height="40dp"
android:layout_alignLeft="@ id/consultation_et_phone"
android:layout_alignStart="@ id/consultation_et_phone"
android:layout_below="@ id/consultation_et_phone"
android:layout_marginTop="22dp"
android:background="@drawable/input_bg"
android:ems="10"
android:inputType="textPersonName"
android:paddingLeft="15dp"
android:paddingRight="15dp"
android:spinnerMode="dialog" / 2、java创建自定义参数
代码语言：javascript复制Spinner consultation_et_section;//挂号科室：3、获取选择控件(Spinner)
代码语言：javascript复制consultation_et_section = (Spinner) findViewById(R.id.consultation_et_section);4、获取JSON数据和绑定数据，可以参考前一篇文章
(1)、创建自定义参数
代码语言：javascript复制List<String listMemDoctorData = null;(2)、获取数据和绑定数据
代码语言：javascript复制/**
* 获取JSON医生信息数据
*/
public void findDoctorData(int sectionId){
AsyncHttpClient client = new AsyncHttpClient();
client.get(AbAppConfig.DATA_URL "appGVConsultation/findDoctorData?sectionId=" sectionId, null, new AsyncHttpResponseHandler() {
@Override
public void onSuccess(int statusCode, Header[] headers, byte[] responseBody) {
try {
JSONObject object = new JSONObject(new String(responseBody));//获取json数据
JSONArray jsonArray = object.getJSONArray("obj");//获取数据集名称为obj的数据
Log.d("jsonArray数据输出：", String.valueOf(jsonArray));
listMemDoctor = new ArrayList< ();
for (int i = 0; i < jsonArray.length();i ) {
MemDoctor doctor = MemDoctor.doctorData(jsonArray.getJSONObject(i));//把数据存在novels集合中
if (doctor != null){
listMemDoctor.add(doctor);
}
}
if (jsonArray.length() 0){
listMemDoctorData = new ArrayList< ();
doctor_id = listMemDoctor.get(0).id;//获取第一个医生的ID
for (int i = 0; i < listMemDoctor.size(); i ){
MemDoctor section = listMemDoctor.get(i);
listMemDoctorData.add(section.doctorName);
}
//建立 Adapter并且绑定数据源
ArrayAdapter<String arrayAdapter = new ArrayAdapter< (GV_Consultation.this, android.R.layout.simple_spinner_item, listMemDoctorData);
//设置样式
arrayAdapter.setDropDownViewResource(android.R.layout.simple_list_item_single_choice);
//绑定 Adapter到控件
consultation_et_doctor.setAdapter(arrayAdapter);
}else {
consultation_et_doctor.setAdapter(null);
doctor_id = 0;
Toast.makeText(GV_Consultation.this, "该科室没有医生信息数据", Toast.LENGTH_SHORT).show();
}
} catch (JSONException e) {
Toast.makeText(GV_Consultation.this, "数据请求失败，请稍后重试", Toast.LENGTH_SHORT).show();
}
}
@Override
public void onFailure(int statusCode, Header[] headers, byte[] responseBody, Throwable error) {
//请求失败的回调处理
Toast.makeText(GV_Consultation.this, "请链接网络，稍后重试", Toast.LENGTH_SHORT).show();
}
});
}5、创建点击事件
代码语言：javascript复制//医生选择点击事件
consultation_et_doctor.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<? parent, View view, int pos, long id) {
doctor_id = listMemDoctor.get((int) id).id;//获取选择医生的ID
}
@Override
public void onNothingSelected(AdapterView<? parent) {
}
});以上就是本文的全部内容，希望对大家的学习有所帮助。
