更改editText字段的setError方法的文本颜色

Question

editTextField = findViewById<EditText>(R.id.nameText)
editTextField.setError(“error message”)

For some reason the error messages come with an unreadable combination of darkish background and black text. The old answers for this question are about a deprecated fromHtml method...

Answer 1

Try This To Use Html.fromHtml() in all APIs :-

     @SuppressWarnings("deprecation") 
       public static Spanned fromHtml(String html)
       { 
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
        return Html.fromHtml(html, Html.FROM_HTML_MODE_LEGACY); 
        } else{ 
        return Html.fromHtml(html);
       }

Just Use It With Flag Parameter
Flag Parameters Are :-

public static final int FROM_HTML_MODE_COMPACT = 63;
public static final int FROM_HTML_MODE_LEGACY = 0;
public static final int FROM_HTML_OPTION_USE_CSS_COLORS = 256;
public static final int FROM_HTML_SEPARATOR_LINE_BREAK_BLOCKQUOTE = 32;
public static final int FROM_HTML_SEPARATOR_LINE_BREAK_DIV = 16;
public static final int FROM_HTML_SEPARATOR_LINE_BREAK_HEADING = 2;
public static final int FROM_HTML_SEPARATOR_LINE_BREAK_LIST = 8;
public static final int FROM_HTML_SEPARATOR_LINE_BREAK_LIST_ITEM = 4;
public static final int FROM_HTML_SEPARATOR_LINE_BREAK_PARAGRAPH = 1;
public static final int TO_HTML_PARAGRAPH_LINES_CONSECUTIVE = 0;
public static final int TO_HTML_PARAGRAPH_LINES_INDIVIDUAL = 1;

Answer 2

Try this

    String errorString = "This field cannot be empty";  // Your custom error message.
    ForegroundColorSpan foregroundColorSpan = new ForegroundColorSpan(errorColor);
    SpannableStringBuilder spannableStringBuilder = new SpannableStringBuilder(errorString);
    spannableStringBuilder.setSpan(foregroundColorSpan, 0, errorString.length(), 0);
    editTextView.setError(spannableStringBuilder);
