//get first letter of each String item
String firstLetter = String.valueOf(getItem(position).charAt(0));
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);我的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" />

使用子字符串()而不是chaAt()
String firstTwoChars = getItem(position).subString(0,2); 页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
