How to draw text with different stroke and fill colors?

问题

I want to display text as below in my app. I am using Paint class with style FILL_AND_STROKE to achieve this. But only one method setColor() is available to set the color.

How do I set different stroke and fill colors?

回答1:

Inside custom TextView (does not work in EditText):

@Override
public void onDraw(Canvas canvas)
{
    final ColorStateList textColor = getTextColors();

    TextPaint paint = this.getPaint();

    paint.setStyle(Style.STROKE);
    paint.setStrokeJoin(Join.ROUND);
    paint.setStrokeMiter(10);
    this.setTextColor(strokeColor);
    paint.setStrokeWidth(strokeWidth);

    super.onDraw(canvas);
    paint.setStyle(Style.FILL);

    setTextColor(textColor);
    super.onDraw(canvas);
}

Don't use FILL_AND_STROKE. Draw once with FILL and then change the color and draw with STROKE.

(That works for rectangles. I'm not sure STROKE works at all for text. You'll have to try it and find out.)

not perfectly sure, but maybe you could use this:

 TextView test = (TextView) findViewById(R.id.test);

 test.setShadowLayer(float, float, float, int);

I used the first solution above to come up with this idea: put down a larger STROKE, text and then overlay it with a smaller FILL_AND_STROKE text:

mScorePaint = new TextPaint();
mScorePaint.setTextSize(63);
mScorePaint.setStyle(Style.STROKE);
mScorePaint.setStrokeJoin(Join.ROUND);
mScorePaint.setStrokeMiter(10.0f);
mScorePaint.setStrokeWidth(frameWidth/50.0f); // about 12
mScorePaint.setColor(0xffff0000); // black

c.drawText(Integer.toString(mScore), x, y, mScorePaint);  // red first

mScorePaint.setStrokeWidth(frameWidth/125.0f); // about 5
mScorePaint.setColor(0xff000000); // red

c.drawText(Integer.toString(mScore), x, y, mScorePaint);  // black on top

Because the FILL alone was not seeing any of the Stroke attributes and was coming out very thin.
