Question

我创建了自定义视图以在其中绘制自定义语音气泡我想在自定义视图上放一些文字。我使用 drawTextOnPath 但它无法正常工作，我希望文本逐行显示。

自定义视图 - 语音气泡

Paint paint = new Paint();

paint.setColor(Color.BLACK);
paint.setAntiAlias(true);
paint.setStrokeWidth(2);
paint.setStrokeJoin(Paint.Join.ROUND);
paint.setStrokeCap(Paint.Cap.ROUND);      
paint.setPathEffect(new CornerPathEffect(15) );  
paint.setStyle(Paint.Style.FILL_AND_STROKE);
paint.setDither(true);
paint.setShader(new LinearGradient(0, 0, 0, getHeight(), Color.BLACK, Color.WHITE,
                                                           Shader.TileMode.MIRROR));
Path path = new Path();         
paint.setShadowLayer(4, 2, 2, 0x80000000);
path.moveTo(myPath[0].x, myPath[0].y);
for (int i = 1; i < myPath.length; i++){
    path.lineTo(myPath[i].x, myPath[i].y);                  
}
path.close();
canvas.clipPath(path);
canvas.drawPath(path, paint);
canvas.save();
paint = new Paint();
paint.setColor(Color.WHITE);
canvas.drawTextOnPath(MessageBody, path, 10, 10, paint);

感谢。

Answer 1

这样的事情？

Paint paint = new Paint();
paint.setColor(Color.WHITE);
paint.setStyle(Style.FILL);
canvas.drawPaint(paint);
...
//tell the paint of the new color
paint.setColor(android.R.color.black);
paint.setTextSize(20);
canvas.drawText("Some Text", 10, 25, paint);

编辑：

然后为什么不这样呢

Path path = new Path();
path.addCircle(width/2, height/2, radius, Path.Direction.CW);

Paint paint = new Paint();
paint.setColor(Color.WHITE);
paint.setTextSize(20);
canvas.drawTextOnPath("Some Text", path, 0, 0, paint);

编辑nr2：

为什么不添加一个矩形？

path.addRect(left, top, right, bottom, Direction.CW);

或

path.addRect(rect, Direction.CW);

Answer 2

我在讲话泡泡中创建了一个矩形，如此

Rect rcText;
rcText = new Rect(rcBounds);//rcBounds is y speech bubble rect
canvas.save();

限制绘制区域

canvas.cliprect(rect);

然后像这样在语音气泡中画出文字

canvas.drawtext(mytext,rect.left,rect.top,paint);
canvas.restore();

谢谢mc_fish。
