How to change spinner text size and text color?

Question

In my Android application, I am using spinner, and I have loaded data from the SQLite database into the spinner, and it\'s working properly. Here is the code for that.

Answer 1

If you want a simple method, in order to add items to a dropdown, you usually add them to the strings.xml. Here is an example on how to add colour by using the strings.xml file:

SELECT AGE RANGE

<string-array name="age_array">

   <item> 0-6 </item>                               //No custom colour

  <item><font fgcolor='#FF4CD964'> 12+ </font></item> //With custom colour

</string-array>

Answer 2

we can change style of spinner textview set theme for spinner like this:

styles.xml:

<style name="mySpinnerItemStyle" parent="@android:style/Widget.Holo.DropDownItem.Spinner">
    <item name="android:textSize">@dimen/_11ssp</item>
    <item name="android:textColor">@color/blue</item>
    <item name=...</item>
</style>

then

<Spinner
                    android:theme="@style/mySpinnerItemStyle"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"/>

if you want to change spinner textview attribute programtically:

Programatically:

val textView = (view.getChildAt(0) as TextView)
textView.setTextColor(resources.getColor(R.color.dark_mode))

    String typeroutes[] = {"Select","Direct","Non Stop"};
    Spinner typeroute;

    typeroute = view.findViewById(R.id.typeroute);

    final ArrayAdapter<String> arrayAdapter5 = new ArrayAdapter<String>(
                getActivity(), android.R.layout.simple_spinner_item, typeroutes) {
            @Override
            public boolean isEnabled(int position) {
                if (position == 0) {
                    // Disable the first item from Spinner
                    // First item will be use for hint
                    return false;
                } else {
                    return true;
                }
            }

            public View getView(int position, View convertView, ViewGroup parent) {
                View v = super.getView(position, convertView, parent);
                ((TextView) v).setTextSize(TypedValue.COMPLEX_UNIT_DIP, 16);
                ((TextView) v).setTextColor(Color.parseColor("#ffffff"));
                return v;
            }         ---->in this line very important so add this

            @Override
            public View getDropDownView(int position, View convertView,
                                        ViewGroup parent) {
                View view = super.getDropDownView(position, convertView, parent);
                TextView tv = (TextView) view;
                if (position == 0) {
                    // Set the hint text color gray
                    tv.setTextColor(Color.GRAY);
                } else {
                    tv.setTextColor(Color.BLACK);
                }
                return view;
            }
        };

        arrayAdapter5.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

        typeroute.setAdapter(arrayAdapter5);

that's all enjoy your coding...

Answer 4

Simple and crisp...:

private OnItemSelectedListener OnCatSpinnerCL = new AdapterView.OnItemSelectedListener() {
    public void onItemSelected(AdapterView<?> parent, View view, int pos, long id) {

       ((TextView) parent.getChildAt(0)).setTextColor(Color.BLUE);
       ((TextView) parent.getChildAt(0)).setTextSize(5);

    }

    public void onNothingSelected(AdapterView<?> parent) {

    }
};

Answer 5

I have done this as following.I have use getDropDownView() and getView() methods.

Use getDropDownView() for opened Spinner.

@Override
public View getDropDownView(int position, View convertView, ViewGroup parent) {
  View view = convertView;
  if (view == null) {
    LayoutInflater vi = (LayoutInflater) activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    view = vi.inflate(R.layout.context_row_icon, null);
  }
  TextView mTitle = (TextView) view.findViewById(R.id.context_label);
  ImageView flag = (ImageView) view.findViewById(R.id.context_icon);                

  mTitle.setText(values[position].getLabel(activity));

  if (!((LabelItem) getItem(position)).isEnabled()) {
    mTitle.setTextColor(activity.getResources().getColor(R.color.context_item_disabled));
  } else {
    mTitle.setTextColor(activity.getResources().getColor(R.color.context_item));
  }
  return view;
}

And Use getView() for closed Spinner.

@Override
public View getView(int position, View convertView, ViewGroup parent) {
  View view = convertView;
  if (view == null) {
    LayoutInflater vi = (LayoutInflater) activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    view = vi.inflate(R.layout.context_row_icon, null);
  }
  TextView mTitle = (TextView) view.findViewById(R.id.context_label);
  ImageView flag = (ImageView) view.findViewById(R.id.context_icon);

  mTitle.setText(values[position].getLabel(activity));
  mTitle.setTextColor(activity.getResources().getColor(R.color.context_item_disabled));

  return view;
}

Answer 6

To prevent lagging, you need to not only set the text properties in the onItemSelected listener, but also in the Activity's onCreate method (but it's a little tricky).

Specifically, you need to put this in onCreate after setting the adapter:

spinner.setSelection(0, true);
View v = spinner.getSelectedView();
((TextView)v).setTextColor(backgroundColor);

And then put this in onItemSelected:

((TextView) view).setTextColor(backgroundColor);

Here is a full example:

@Override  
protected void onCreate(Bundle savedInstanceState)
{  
    Spinner spinner = (Spinner) findViewById(R.id.spinner); 

    //Set the choices on the spinner by setting the adapter.  
    spinner.setAdapter(new SpinnerAdapter(toolbar.getContext(), new String[]{"Overview", "Story", "Specifications", "Poll", "Video"}, accentColor, backgroundColor));

    //Set the text color of the Spinner's selected view (not a drop down list view) 
    spinner.setSelection(0, true);
    View v = spinner.getSelectedView();
    ((TextView)v).setTextColor(backgroundColor);

    //Set the listener for when each option is clicked.  
    spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener()
    {  

        @Override  
        public void onItemSelected(AdapterView<?> parent, View view, int position, long id)
        {  
           //Change the selected item's text color  
           ((TextView) view).setTextColor(backgroundColor);
        }  

        @Override  
        public void onNothingSelected(AdapterView<?> parent)
        {  
        }  
    });  

}
