更改部分EditText文本颜色[关闭]

如果您只需要对 EditText ,您可以使用 Spannable 在这种情况下 ForegroundColorSpan 会是个好的开始。

简化的解决方案类似于:

String usernameToLookFor = "michael";
String myString = "Welcome world to michael !!";

//Create spannable string
SpannableString spannableString = new SpannableString(myString);

//Determine the start and end of the span i.e. which section you want colored
//Note: loop it if username appears multiple times in main string
int usernameStart = myString.indexOf(usernameToLookFor);
int usernameEnd = usernameStart + usernameToLookFor.length;

//Apply color spannable to SpannableString
spannableString.setSpan(ForegroundColorSpan(ContextCompat.getColor(context, R.color.highlighted_color)),usernameStart, usernameEnd, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

//Set spannable to edit text
myEditText.setText(spannableString);

很粗糙的回答。希望能有所帮助。

可以将代码中的HTML插入到文本视图中,然后可以在文本的特定部分定义颜色:

myTextView
.setText(
  Html.fromHtml(
   "Your text<span color='<your color>'>colored part</span> rest of your text"
));
