如何在自定義視圖中繪制文本？

Question

我已創建自定義視圖以在其中繪制自定義語音氣泡，我想在自定義視圖上放置一些文本。 我使用drawTextOnPath，但它不能正常工作，我希望文本逐行顯示。

自定義視圖 - 語音泡沫

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);

謝謝。

Answer 1

這樣的事情？

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);

編輯：

那么為什么不是這樣的

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);

編輯nr2：

為什么不加一個矩形？

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

要么

path.addRect(rect, Direction.CW);

Answer 2

我在講話泡泡中創建了一個矩形

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

限制抽獎區域

canvas.cliprect(rect);

並像這樣畫出講話泡泡里面的文字

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