android – 在TextInputLayout中更改单个字母或字母的提示颜色

我已经在我的Activity中以编程方式定义了TextInputLayout.我已经在TextInputLayout中添加了EditText,以编程方式.

现在,我必须设置该edittext的提示颜色.在这里,我只需要改变提示的单个字母的颜色.

Example - Hint is like, Firstname *. Here  i want to change the color of "*" to Red and remaining hint as black in color.

我已经尝试过Html和Spannable String,但两者都不适用于TextInputLayout.

对于Spannable我做了

SpannableString redSpannable = new SpannableString(red);
redSpannable.setSpan(new ForegroundColorSpan(Color.RED), 0, red.length(), 0);
Spanned hint = Html.fromHtml(string + redSpannable);
etDefault[j].setHint(hint);

对于HTML,

I used "font-color"

如果有人知道这一点,那么分享您的意见.

解决方法:

按照Android Issue Tracker,

Setting the hint to the editText respects the span, but the label does
not float on focus.

editText.setHint(hint);

Setting the hint to the textInputLayout ignores the span

textInputLayout.setHint(hint);

TextInputLayout uses internal class CollapsingTextHelper to draw the
hint, which does not support spans.

正如他们所说,
