Android EditText hint uses the same font that the EditText has

Question

I have defined a font for a EditText and now the EditText hint also shows that font, but i need to use a different font for EditText hint, is there a way to achieve this?

Answer 1

Android EditText hint uses the same font that the EditText has

EditText uses textview_hint layout to show ErrorPopup popup message.so try as to set different typeface for Hint as:

 LayoutInflater inflater = LayoutInflater.from(<Pass context here>);
 TextView hintTextView = (TextView) inflater.inflate(
                        com.android.internal.R.layout.textview_hint, null);
 hintTextView.setTypeface(< Typeface Object>);

EDIT: Because EdiText internally show Hint popup using ErrorPopup.

No need to use reflection. You can achieve it by creating your own TypefaceSpan.

public class CustomTypefaceSpan extends TypefaceSpan
{
    private final Typeface mNewType;

    public CustomTypefaceSpan(Typeface type)
    {
        super("");
        mNewType = type;
    }

    public CustomTypefaceSpan(String family, Typeface type)
    {
        super(family);
        mNewType = type;
    }

    @Override
    public void updateDrawState(TextPaint ds)
    {
        applyCustomTypeFace(ds, mNewType);
    }

    @Override
    public void updateMeasureState(TextPaint paint)
    {
        applyCustomTypeFace(paint, mNewType);
    }

    private static void applyCustomTypeFace(Paint paint, Typeface tf)
    {
        int oldStyle;
        Typeface old = paint.getTypeface();
        if (old == null)
        {
            oldStyle = 0;
        }
        else
        {
            oldStyle = old.getStyle();
        }

        int fake = oldStyle & ~tf.getStyle();
        if ((fake & Typeface.BOLD) != 0)
        {
            paint.setFakeBoldText(true);
        }

        if ((fake & Typeface.ITALIC) != 0)
        {
            paint.setTextSkewX(-0.25f);
        }

        paint.setTypeface(tf);
    }
}

Use it as:

// set font to EditText itself
Typeface editTextTypeface = Typeface.createFromAsset(getAssets(), "font1.ttf");
EditText editText = (EditText) findViewById(R.id.normalEditText);
editText.setTypeface(editTextTypeface);

// set font to Hint
Typeface hintTypeface = Typeface.createFromAsset(getAssets(), "font2.ttf");
TypefaceSpan typefaceSpan = new CustomTypefaceSpan(hintTypeface);
SpannableString spannableString = new SpannableString("some hint text");
spannableString.setSpan(typefaceSpan, 0, spannableString.length(), Spanned.SPAN_INCLUSIVE_EXCLUSIVE);
editText.setHint(spannableString);
