Android BlackBerry 文本对齐方式对比

canvas.drawText("this is demo", imageWidth, 49, p);

这句话则说明居右对齐的点在imageWidth的位置，这都是相对的概念。

下面是BlackBerry的代码:

Java代码

Bitmap bitmap = new Bitmap(imageWidth, imageHeight);

Graphics graphics = Graphics.create(bitmap);

graphics.drawText("This is the demo", 0, 0, Graphics.HCENTER,

Display.getWidth());

Bitmap bitmap = new Bitmap(imageWidth, imageHeight);

Graphics graphics = Graphics.create(bitmap);

graphics.drawText("This is the demo", 0, 0, Graphics.HCENTER,

Display.getWidth());

graphics.drawText("This is the demo", 0, 0, Graphics.HCENTER,

Display.getWidth());

这段代码是说让文本居中对齐 Graphics.HCENTER，那么Display.getWidth()就是所画的区域宽度。

另外BlackBerry的对齐方式还能进行组合使用，比如：

Java代码

graphics.drawText("This is the demo", 0, 0, Graphics.HCENTER|Graphics.VFULL,

Display.getWidth());

graphics.drawText("This is the demo", 0, 0, Graphics.HCENTER|Graphics.VFULL,

Display.getWidth());

所以Android和BB在文本对齐的方式上有很大的不同。
