在我们的项目中，我们不对Label和dropdown进行硬编码，而是将值从JSON分配给Label。我不知道如何将性别array分配给dropdown。
这是从URL

我想使用性别数组从响应中获取并添加到片段中的Spinner中。
这是onResponse方法中的代码。
heroList = response.body();
data = new ArrayList<>(Arrays.asList(heroList));
Log.d("Data","Datarecevied:"+heroList.getMeetmeConfig().getConfigContent().getGender());
我们该怎么做？
答案 0 :(得分：0)
List anyList = heroList.getMeetmeConfig().getConfigContent().getGender()
Spinner spinner = (Spinner) findViewById(R.id.msSpinnerID);
ArrayAdapter<String> adp = new ArrayAdapter<String>(this,android.R.layout.simple_spinner_item, anyList);
adp.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner.setAdapter(adp);
如果要在对话框上显示
AlertDialog.Builder builderSingle = new AlertDialog.Builder(DialogActivity.this);
builderSingle.setIcon(R.drawable.ic_launcher);
builderSingle.setTitle("Select One Name:-");
final ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>(DialogActivity.this, android.R.layout.select_dialog_singlechoice);
List anyList = heroList.getMeetmeConfig().getConfigContent().getGender()
for(gender : anyList)
{
arrayAdapter.add(gender)
}
builderSingle.setNegativeButton("cancel", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
}
});
builderSingle.setAdapter(arrayAdapter, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
String strName = arrayAdapter.getItem(which);
Log.e("My Selected Gender", strName)
}
});
builderSingle.show();

一旦您有了JSON响应，就会在https://android-arsenal.com/details/1/5313
中找到一个名为Ason的Android库您可以使用库来更轻松地获取要在微调器上使用的数组。它是Android中# your code.....
ptm.tf <- DocumentTermMatrix(apapers)
# using col_sums since it is a document term matrix. If it is a term document matrix use row_sums
frequency <- slam::col_sums(ptm.tf)
# Filtering like findFreqTerms. Find words that occur 10 times or more.
frequency <- frequency[frequency >= 10]
# turn into data.frame if needed:
frequency_df <- data.frame(words = names(frequency ), freq = frequency , row.names = NULL)
的包装。
因此您的数组将按以下方式构造：
org.json将Ason ason = new Ason(urlResponse);
AsonArray genderArray = ason.getJsonArray('meetmeConfig.configContent.gender')
//then u convert the genderArray into an array or ArrayList thats spinners use
ArrayList<String> spinnerItems = new ArrayList();
for (Ason gender : genderArray){
spinnerItems.add(gender.toString());
}
用于微调适配器
答案 2 :(得分：0)
AppCompatSpinner spinner;
spinner = (AppCompatSpinner) findViewById(R.id.spinner);
ArrayList<String> categoryDropDownItems = new ArrayList<String>();
您的回复
categoryDropDownItems.add("<Set Title if you want>");
//Array Response from Server
if (response != null) {
if (response.length() > 0) {
for (int i = 0; i < response.length(); i++) {
try {
JSONObject jsonObject = response.getJSONObject(i);
String dropDownDisplayCategoryName = jsonObject.getString("<YOUR STRIN FROM JSON>");
categoryDropDownItems.add(dropDownDisplayCategoryName);
} catch (JSONException je) {
return null;
}
}
} else {
return null;
}
}
//对于Spinner中的设置数组数据
ArrayAdapter<String> adapter = new ArrayAdapter<String>(getActivity(), R.layout.spinner_item, categoryDropDownItems);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner.setAdapter(adapter);
spinner.setSelection(selection);
如果要将数据从“活动”传递到“片段”，则可以使用
Fragment fragment = new YourFragmentName();
Bundle bundle = new Bundle();
bundle.putString("RESPONSE",<Your Response as a String>);
fragment.setArguments(bundle);
然后像下面那样在Fragment中获取数据
String responseData = getArguments().getString("RESPONSE");
现在，您可以在JSON中转换对象，并从JSON获得Spinner数据，并使用上述代码在ArrayList中添加数据并将其设置为Spinner

只需尝试以下代码，问题便会解决。谢谢
ArrayAdapter<String> genderAdapter;
Spinner spin_gender = findViewById(R.id.spin_gender);
heroList = response.body();
data = new ArrayList<>(Arrays.asList(heroList));
String[] genderArray = heroList.getMeetmeConfig().getConfigContent().getGender()
genderAdapter = new ArrayAdapter<String>(this, R.layout.label, genderArray);
spin_gender.setAdapter(genderAdapter);
