Android's custom selector network to obtain information
1681205207141.png
1. Obtain list data from okhttp network
2. Write the obtained data into ArrayList
3. Convert ArrayList to array String[]
4. Pass the converted array data into the final custom selector
Core code:
DeviceBean data = new Gson().fromJson(responseData, DeviceBean.class);
List<String> list3 = new ArrayList<>();
for (int i = 0; i < data.getRows().size(); i++) {
System.out.println("111111>>打印每条数据>>" + data.getRows().get(i).getDeviceCode()); // 打印
String deviceCode = data.getRows().get(i).getDeviceName();
list3.add(deviceCode); // 1,获取数据写入ArrayList
}
System.out.println("111111>>打印list3>>" + list3); // 打印
int size = list3.size(); // 2,获取ArrayList长度
String[] array = (String[]) list3.toArray(new String[size]); // 3,ArrayList 转数组 String[]
System.out.println("111111>>array>>" + array);
OptionPicker picker = new OptionPicker(MattingActivity.this,
array // 4,将转好的数组数据传入 最终自定义选择器中。原 new String[] {"一个","两个"}
);
picker.setOffset(2);
picker.setSelectedIndex(1);
picker.setTextSize(11);
picker.setOnOptionPickListener(new OptionPicker.OnOptionPickListener() {
@Override
public void onOptionPicked(String option) {
showToast(option);
}
private void showToast(String option) {
optiondeviceid = option;
matting_tv01.setText(option);
// Log.d("111111" + TAG, "initView02>>" + option);
}
});
picker.show();
Full code:
matting_tv01.setOnClickListener(v ->
// 点击按钮，获取数据
getHttp_deviceid();
);
/**
* okhttp get请求
*/
private String optiondeviceid = null;
public void getHttp_deviceid() {
// // 获取传递的值
// Intent intentid = getIntent();
// // 取 项目id
// String getProjectId = intentid.getStringExtra("getProjectId");
// String getProjectName = intentid.getStringExtra("getProjectName");
// Log.d("111111", "initView01>>" + getProjectId + getProjectName);
// 取 Token
SharedPreferences sharedPreferences = getSharedPreferences("logonsp", MODE_PRIVATE);
String token = sharedPreferences.getString("token", "");
Log.d("111111ProjectFragment>>", "getAccess_token:" + sharedPreferences.getString("token", ""));
// // 账号密码转为Json格式传给后台
// MediaType JSON = MediaType.parse("application/json; charset=utf-8");
// // 将要传的参数保存进Json对象
// JSONObject jsJson = new JSONObject();
// try {
// jsJson.put("cruiseId", "0");
// } catch (JSONException e) {
// e.printStackTrace();
// }
// Log.d("111111 jsJson ====", ":" + jsJson);
//
// // 创建一个RequestBody(参数1：数据类型 参数2传递的json串)
// RequestBody requestBody = RequestBody.create(JSON, String.valueOf(jsJson));
// 3 . 构建Request,将FormBody作为Post方法的参数传入
Request request = new Request.Builder()
.url(HTTP_URL + "/facility/device/list") // "?projectId=" + getProjectId
.addHeader("Authorization", "Bearer " + token)
.addHeader("Content-Type", "application/json;charset=UTF-8")
// .post(requestBody)
.build();
// 1 . 拿到OkHttpClient对象
OkHttpClient client = new OkHttpClient.Builder().readTimeout(5000, TimeUnit.SECONDS).build();
Call call = client.newCall(request);
call.enqueue(new Callback() {
@Override
public void onFailure(Call call, IOException e) {
}
@Override
public void onResponse(Call call, Response response) throws IOException {
// 请求成功返回结果,如果希望返回的是字符串
final String responseData = response.body().string();
// 如果希望返回的是inputStream,有inputStream我们就可以通过IO的方式写文件.
// InputStream responseStream=response.body().byteStream();
// 注意，此时的线程不是ui线程，如果此时我们要用返回的数据进行ui更新，操作控件，就要使用相关方法
runOnUiThread(new Runnable() {
@Override
public void run() {
// 更新UI的操作
DeviceBean data = new Gson().fromJson(responseData, DeviceBean.class);
List<String> list3 = new ArrayList<>();
for (int i = 0; i < data.getRows().size(); i++) {
System.out.println("111111>>打印每条数据>>" + data.getRows().get(i).getDeviceCode()); // 打印
String deviceCode = data.getRows().get(i).getDeviceName();
list3.add(deviceCode); // 1,获取数据写入ArrayList
}
System.out.println("111111>>打印list3>>" + list3); // 打印
int size = list3.size(); // 2,获取ArrayList长度
String[] array = (String[]) list3.toArray(new String[size]); // 3,ArrayList 转数组 String[]
System.out.println("111111>>array>>" + array);
OptionPicker picker = new OptionPicker(MattingActivity.this,
array // 4,将转好的数组数据传入 最终自定义选择器中。原 new String[] {"一个","两个"}
);
picker.setOffset(2);
picker.setSelectedIndex(1);
picker.setTextSize(11);
picker.setOnOptionPickListener(new OptionPicker.OnOptionPickListener() {
@Override
public void onOptionPicked(String option) {
showToast(option);
}
private void showToast(String option) {
optiondeviceid = option;
matting_tv01.setText(option);
// Log.d("111111" + TAG, "initView02>>" + option);
