问题描述
我想创建一个 TextView
并有两个文本或两种颜色的文本...
并且我希望样品店颜色更改为红色并搜索为蓝色...
我的 xml 代码:
<TextView
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:layout_marginLeft="5dp"
android:layout_marginTop="5dp"
android:layout_marginRight="5dp"
android:layout_marginBottom="5dp"
android:background="@drawable/search_bg"
android:drawableRight="@drawable/search"
android:drawableTint="@color/day_dark_blue"
android:paddingRight="15dp"
android:gravity="center"
android:layout_gravity="center|center_vertical"
android:text="search in Sample Shop"
android:textColor="@color/day_dark_blue"
android:textSize="18sp" />
解决方法
您可以尝试使用 SpannableString
// in the .kt file
val spannable = SpannableString("search in the Sample Shop")
spannable.setSpan(
ForegroundColorSpan(Color.RED),10,20,Spannable.SPAN_EXCLUSIVE_EXCLUSIVE)
// 10,20: start and end index of Sample Shop
myTextView.text = spannable
一篇有用的文章:Spantastic text styling with Spans
,您可以使用 SpannableString 来实现相同的效果。
TextView TV = (TextView)findViewById(R.id.textView);
Spannable wordtoSpan = new SpannableString("search in Sample Shop");
wordtoSpan.setSpan(new ForegroundColorSpan(Color.BLUE),9,Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
wordtoSpan.setSpan(new ForegroundColorSpan(Color.RED),21,Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
TV.setText(wordtoSpan);
