Paint 属性在应用两次时不起作用

Question

我正在尝试创建具有白色和黑色轮廓的自定义效果字体（又名 "meme font"）。我在 canvas 的两端都有 2 个文本，但其中只有一个反映了更改。这是到目前为止我所拥有的：

这是我的代码：

        Canvas canvas = new Canvas(mutableBitmap);

        TextPaint topFillPaint = new TextPaint();
        TextPaint bottomFillPaint = new TextPaint();

        TextPaint topStrokePaint = new TextPaint();
        TextPaint bottomStrokePaint = new TextPaint();

        Typeface typeface = getResources().getFont(R.font.impact);

        topFillPaint.setColor(Color.WHITE);
        topFillPaint.setTextSize(topTextView.getTextSize());
        topFillPaint.setTypeface(typeface);

        topStrokePaint.setStyle(Paint.Style.STROKE);
        topStrokePaint.setStrokeWidth(8);
        topStrokePaint.setColor(Color.BLACK);
        topStrokePaint.setTextSize(topTextView.getTextSize());
        topStrokePaint.setTypeface(typeface);

        bottomFillPaint.setColor(Color.WHITE);
        bottomFillPaint.setTextSize(bottomTextView.getTextSize());
        bottomFillPaint.setTypeface(typeface);

        bottomStrokePaint.setStyle(Paint.Style.STROKE);
        bottomStrokePaint.setStrokeWidth(8);
        bottomStrokePaint.setColor(Color.BLACK);
        bottomStrokePaint.setTextSize(bottomTextView.getTextSize());
        bottomStrokePaint.setTypeface(typeface);

        float topTextMeasurement = topFillPaint.measureText(topText);
        float bottomTextMeasurement = bottomFillPaint.measureText(bottomText);

        StaticLayout topFillLayout = new StaticLayout(topText, topFillPaint, canvas.getWidth(), Layout.Alignment.ALIGN_CENTER,
                1.0f, 0.0f, false);
        StaticLayout topStrokeLayout = new StaticLayout(topText, topStrokePaint, canvas.getWidth(), Layout.Alignment.ALIGN_CENTER,
                1.0f, 0.0f, false);


        StaticLayout bottomFillLayout = new StaticLayout(bottomText, bottomFillPaint, canvas.getWidth(), Layout.Alignment.ALIGN_CENTER,
                1.0f, 0.0f, false);
        StaticLayout bottomStrokeLayout = new StaticLayout(bottomText, bottomStrokePaint, canvas.getWidth(), Layout.Alignment.ALIGN_CENTER,
                1.0f, 0.0f, false);

        canvas.translate(0,0);
        topFillLayout.draw(canvas);

        canvas.translate(0,0);
        topStrokeLayout.draw(canvas);

        canvas.translate(0, canvas.getHeight() - 210);
        bottomFillLayout.draw(canvas);

        canvas.translate(0, canvas.getHeigth() - 210);
        bottomStrokeLayout.draw(canvas);

Answer 1

您传递给绘制 bottomStrokeLayout 和 bottomFillLayout 的坐标不同。

 canvas.translate(0, canvas.getHeight() - 210);
 bottomFillLayout.draw(canvas);

canvas.translate(0,canvas.getHeight() -210);
bottomStrokeLayout.draw(canvas);
