Question

在将每个字母绘制到画布之前，是否有可用于为每个字母设置动画的解决方案???我搜索互联网，我似乎没有看到任何合理的......

private void draw() {
        SurfaceHolder holder = getSurfaceHolder();
        Canvas canvas = null;
        try {
            canvas = holder.lockCanvas();
            if (canvas != null) {

                // Draw background
                canvas.drawColor(PrefService.getBgColor());                                  

                StaticLayout textLayout = new StaticLayout(TEXT_I_WOULD_LIKE_TO_ANIMATE, textPaint, screenWidth - screenWidth / 8, Layout.Alignment.ALIGN_CENTER, 1.0F, 1.0F, true);
                canvas.translate((screenWidth / 2) - (textLayout.getWidth() / 2), (screenHeight / 2) - ((textLayout.getHeight() / 2)));
                textLayout.draw(canvas);
            }
        } finally {
            if (canvas != null) {              
                    holder.unlockCanvasAndPost(canvas);                   
            }
        }
    }
    handler.removeCallbacks(drawRunner);
    handler.postDelayed(drawRunner, 20000);
}

注意StaticLayout上面的TEXT_I_WOULD_LIKE_TO_ANIMATE变量

任何帮助非常感谢

创建渲染线程，循环绘制方法。然后，您可以为文本变量创建位置，并更改每个帧的文本位置。要在画布上绘制文本，您应该使用canvas.drawText（...）。我希望我能帮到你。
