我完美地創(chuàng)建了動態(tài)微調(diào)器，如下所示 k++; flag=k; final LinearLayout.LayoutParams lparams = new LinearLayout.LayoutParams(380,120); lparams.setMargins(1, 20, 1, 0); colorSpinner[flag] = new Spinner(getActivity()); colorSpinner[flag].setLayoutParams(lparams); colorSpinner[flag].setId(flag); colorSpinner[flag].setAdapter(new ArrayAdapter<String>(getContext(), android.R.layout.simple_spinner_dropdown_item, color_list)); loadColorSpinnerData(URL); colorSpinner[flag].setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() { @Override public void onItemSelected(AdapterView<?> adapterView, View view, int i, long l) { color_id = datalist1.get(i).getId(); } @Override public void onNothingSelected(AdapterView<?> adapterView) { // DO Nothing here } });mLayout.addView(colorSpinner[flag]);color_array.add(colorSpinner[flag]);如何獲取數(shù)組中的顏色I(xiàn)D這是行不通的String[] Acolorid = new String[color_array.size()]; for(int i = 0; i < color_array.size(); i++){ Acolorid[i] = String.valueOf(color_array.get(i).getSelectedItemPosition()+1); //Acolorid[j]= String.valueOf(color_id);//color_array.get(i).getSelectedItem().toString(); Hcolorid=String.join(",",Acolorid); }請給我我想獲取數(shù)組中的顏色I(xiàn)D而不獲取項目位置的解決方案。

一種方法是使用View.setTag（）存儲以后要檢索的數(shù)據(jù)。就像是 ：
public void onItemSelected(AdapterView<?> adapterView, View view, int i, long l)
{
// get some data related to the selected item
color_id = datalist1.get(i).getId();
// attach it to the spinner
adapterView.setTag(color_id);
}
@Override
public void onNothingSelected(AdapterView<?> adapterView) {
// DO Nothing here
}
稍后檢索：
String[] Acolorid = new String[color_array.size()];
for(int i = 0; i < color_array.size(); i++){
// get the saved data
Object data = color_array.get(i).getTag();
if (data != null) {
Acolorid[i] = data.toString();
}
}
Hcolorid=String.join(",",Acolorid);
