For Static Data.
1.Create an ArrayList.
List lmonth=new ArrayList();
2.Populate arraylist.
lmonth.add("0");lmonth.add("1");lmonth.add("2");lmonth.add("3");lmonth.add("4");lmonth.add("5");lmonth.add("6");lmonth.add("7");lmonth.add("8");lmonth.add("9");
lmonth.add("10");lmonth.add("11");
3.Creation of Adapter and adding list to Adapter.
ArrayAdapter<String> dataAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, lmonth);
dataAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
4.Set Adapter to spinner.
Spinner month=(Spinner)findViewById(R.id.spinnermonth);
month.setAdapter(dataAdapters);
This is way of populating a spinner with static data..
For Dynamic data.
1.Create an Adapter.
public class SpinnerCustomAdapter extends BaseAdapter {
private Context mContext;
private List<JobSearchModel> mList=new ArrayList<JobSearchModel>();
private LayoutInflater mLayoutInflater;
private String mType=null;
public SpinnerCustomAdapter(Context mContext, List<JobSearchModel> list) {
this.mContext=mContext;
this.mList=list;
}
@Override
public int getCount() {
return mList.size();
}
@Override
public Object getItem(int i) {
return i;
}
@Override
public long getItemId(int i) {
return i;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder=null;
LayoutInflater layoutInflater=(LayoutInflater)mContext.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
if(convertView==null){
convertView = layoutInflater.inflate(R.layout.layout_spinner, null);
holder = new ViewHolder();
holder.textView2=(TextView)convertView.findViewById(R.id.txt_text2);
convertView.setTag(holder);
}
else {
holder = (ViewHolder) convertView.getTag();
}
JobSearchModel classModel=mList.get(position);
String id = mList.get(position).getId();
if(id.equals("select")){
holder.textView2.setTextColor(mContext.getResources().getColor(R.color.lightblack));
}else{
holder.textView2.setTextColor(mContext.getResources().getColor(R.color.black));
}
holder.textView2.setText(classModel.getDescription());
return convertView;
}
static class ViewHolder{
TextView textView2;
}
}
The XML needed for the Adapter is
<?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">
<TextView
android:id="@+id/txt_text2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Dami"
android:textSize="14sp"
android:layout_marginLeft="5dp"
android:textColor="#4E4E4E"
android:layout_marginTop="5dp"
android:layout_marginBottom="5dp"
/>
<View
android:layout_width="match_parent"
android:layout_height="1dp"
/>
</LinearLayout>
3.Now create a Model class according to the needs.
public class Model {
private String id;
private String description;
public char[] name;
public Model()
{
}
public Model (String id, String description) {
this.id = id;
this.description = description;
}
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getDescription() {
return description;
}
public void setDescription(String description) {
this.description = description;
}
@Override
public String toString() {
final StringBuilder sb = new StringBuilder();
sb.append(String.format("%02d", id)).append(" - ").append(description);
return sb.toString();
}
}
4.Now inside The Main class.
i)Create the Arayylist.
private List<Model> mList = new ArrayList<Model>();
ii)Initialize and define spinner.
Spinner loc = (Spinner) findViewById(R.id.sp_loc);
iii)Set OnItemSelectedListener for Spinner.
loc.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> adapterView, View view, int i, long l) {
}
@Override
public void onNothingSelected(AdapterView<?> adapterView) {
}
});
Now populating the spinner with dynamic data.
eg: code shall be given below.
private void Parsing(JsonParser jsonParser) {
Log.i(">>>ClassResponseloc", "" + jsonParser);
mList = new ArrayList<Model>();
Model classModel = null;
try {
while (jsonParser.nextToken() != JsonToken.END_ARRAY) {
classModel = new JobSearchModel();
while (jsonParser.nextToken() != JsonToken.END_OBJECT) {
String fieldName = jsonParser.getCurrentName();
if ("id".equals(fieldName)) {
jsonParser.nextToken();
classModel.setId((jsonParser.getText()) + "-");
} else if ("name".equals(fieldName)) {
jsonParser.nextToken();
classModel.setDescription(jsonParser.getText());
}
}
mList.add(classModel);
}
SpinnerCustomAdapter adapter = new SpinnerCustomAdapter(this, mList);
loc.setAdapter(adapter);
} catch (JsonParseException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
It might help u.
