[android] How to customize a Spinner in Android

Try this

i was facing lot of issues when i was trying other solution...... After lot of R&D now i got solution

  1. create custom_spinner.xml in layout folder and paste this code

     <?xml version="1.0" encoding="utf-8"?>
    <RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/colorGray">
    <TextView
    android:id="@+id/tv_spinnervalue"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:textColor="@color/colorWhite"
    android:gravity="center"
    android:layout_alignParentLeft="true"
    android:textSize="@dimen/_18dp"
    android:layout_marginTop="@dimen/_3dp"/>
    <ImageView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentRight="true"
    android:background="@drawable/men_icon"/>
    </RelativeLayout>
    
  2. in your activity

    Spinner spinner =(Spinner)view.findViewById(R.id.sp_colorpalates);
    String[] years = {"1996","1997","1998","1998"};
    spinner.setAdapter(new SpinnerAdapter(this, R.layout.custom_spinner, years));
    
  3. create a new class of adapter

    public class SpinnerAdapter extends ArrayAdapter<String> {
    private String[] objects;
    
    public SpinnerAdapter(Context context, int textViewResourceId, String[] objects) {
        super(context, textViewResourceId, objects);
        this.objects=objects;
    }
    
    @Override
    public View getDropDownView(int position, View convertView, @NonNull ViewGroup parent) {
        return getCustomView(position, convertView, parent);
    }
    
    @NonNull
    @Override
    public View getView(int position, View convertView, @NonNull ViewGroup parent) {
        return getCustomView(position, convertView, parent);
    }
    
    private View getCustomView(final int position, View convertView, ViewGroup parent) {
        View row = LayoutInflater.from(parent.getContext()).inflate(R.layout.custom_spinner, parent, false);
        final TextView label=(TextView)row.findViewById(R.id.tv_spinnervalue);
        label.setText(objects[position]);
        return row;
    }
    }
