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

For someone who needs only Style way for AppCompat.

Result

styles.xml

<resources>
    ... 
    <style name="Spinner" parent="Widget.AppCompat.Light.DropDownItem.Spinner">
        <item name="android:paddingStart">0dp</item>
        <item name="android:paddingEnd">0dp</item>
        <item name="android:textColor">@color/material_grey_700</item>
        <item name="android:textSize">12sp</item>
    </style>
</resources>

your_spinner_layout.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />
    ...

    <android.support.v7.widget.AppCompatSpinner
        android:id="@+id/content_spinner"
        style="@style/Widget.AppCompat.Spinner.Underlined"
        android:layout_width="140dp"
        android:layout_height="wrap_content"
        android:entries="@array/shipping_tracking_carrier_names"
        android:spinnerMode="dropdown"
        android:theme="@style/Spinner" />

    <EditText
        android:id="@+id/content_input"
        android:layout_width="140dp"
        android:layout_height="wrap_content"
        android:inputType="text"
        android:maxLines="1"
        android:paddingEnd="8dp"
        android:paddingStart="8dp"
        android:textColor="@color/material_grey_700"
        android:textSize="12sp" />

    ...
</LinearLayout>    

Plus
And if you want to set android:entries programmatically with defined style.
Try this.

AppCompatSpinner spinner = findViewById(R.id.content_spinner);
CharSequence[] entries = getResources().getTextArray(R.array.shipping_tracking_carrier_names);
ArrayAdapter<CharSequence> adapter = new ArrayAdapter<>(spinner.getContext(), android.R.layout.simple_spinner_item, entries);
adapter.setDropDownViewResource(android.support.v7.appcompat.R.layout.support_simple_spinner_dropdown_item);
spinner.setAdapter(adapter);

As in the code, using same Context with the Spinner is most important thing.

spinner.getContext()

Answer 2

Simplest: Works for me

TextView spinnerText = (TextView) spinner.getChildAt(0);

spinnerText.setTextColor(Color.RED);

Answer 3

just add new style like this:

<style name="mySpinnerItemStyle" parent="ThemeOverlay.AppCompat.Dark">
    <item name="android:textColor">#000</item>
    <item name="android:color">#000</item>
</style>

and use it:

<Spinner
      android:id="@+id/spinnerCategories"
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      style="@style/mySpinnerItemStyle"
      android:layout_margin="5dp" />

Answer 4

Try this method. It is working for me.

@Override
public void onItemSelected(AdapterView<?> adapterView, View view, int i, long l) {
    TextView textView = (TextView) view;
    ((TextView) adapterView.getChildAt(0)).setTextColor(Color.RED);
    ((TextView) adapterView.getChildAt(0)).setTextSize(20);
    Toast.makeText(this, textView.getText()+" Selected", Toast.LENGTH_SHORT).show();
}

Answer 5

First we have to create the simple xml resource file for the textview like as below:

<?xml version="1.0" encoding="utf-8"?>

 <TextView  
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent" 
    android:layout_height="wrap_content"
    android:textSize="20sp"
    android:gravity="left"  
    android:textColor="#FF0000"         
    android:padding="5dip"
    />   

and save it. after set on your adapterlist.

Answer 6

Make a custom XML file for your spinner item.

spinner_item.xml:

Give your customized color and size to text in this file.

<?xml version="1.0" encoding="utf-8"?>

<TextView  
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent" 
    android:layout_height="wrap_content"
    android:textSize="20sp"
    android:gravity="left"  
    android:textColor="#FF0000"         
    android:padding="5dip"
    />

Now use this file to show your spinner items like:

ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, R.layout.spinner_item,list);

You don't need to set the drop down resource. It will take spinner_item.xml only to show your items in spinner.
