ColorGenerator generator = ColorGenerator.MATERIAL; // or use DEFAULT
// generate random color
int color = generator.getColor(getItem(position));

TextDrawable drawable = TextDrawable.builder().buildRound(firstLetter,//radius in px color);

My xml:

<?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="wrap_content"
    android:orientation="horizontal"
    android:padding="5dp">

    <ImageView
        android:id="@+id/image_view"
        android:src="@drawable/ic_home_black_24dp"
        android:layout_width="40dp"
        android:layout_height="40dp" />

    <TextView
        android:id="@+id/text"
        android:paddingLeft="20sp"
        android:textSize="22sp"
        android:fontFamily="sans-serif"
        android:textColor="@color/darkcolor"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="John" />
</LinearLayout>

Use substring() instead of chaAt()

String firstTwoChars = getItem(position).subString(0,2);
