Android的Canvas.drawText [英] Android Canvas.drawText

问题描述

我有一个观点，我跟在OnDraw中（画布油画）方法Canvas对象绘制。我的code是：

I have a view, I'm drawing with the Canvas object in the onDraw(Canvas canvas) method. My code is:

Paint paint = new Paint();
paint.setColor(Color.WHITE);
paint.setStyle(Style.FILL);
canvas.drawPaint(paint);

paint.setColor(android.R.color.black);
paint.setTextSize(20);
canvas.drawText("Some Text", 10, 25, paint);

问题是，文本不通过后台显示，我究竟做错了什么？如果我删除canvas.drawPaint（油漆）和paint.setColor（android.R.color.black），你可以看到屏幕上的文字......

The problem is the text doesn't show through the background, what am I doing wrong? If I remove the canvas.drawPaint(paint) and paint.setColor(android.R.color.black) you can see the text on the screen.....

推荐答案

曾为这一点，事实证明，android.R.color.black是不一样的Color.BLACK。改变了code到：

Worked this out, turns out that android.R.color.black is not the same as Color.BLACK. Changed the code to:

Paint paint = new Paint(); 
paint.setColor(Color.WHITE); 
paint.setStyle(Style.FILL); 
canvas.drawPaint(paint); 

paint.setColor(Color.BLACK); 
paint.setTextSize(20); 
canvas.drawText("Some Text", 10, 25, paint); 

和这一切工作正常现在！

and it all works fine now!!
