我需要使用
绘制文字canvas.drawText(“1”,x,y,paint);
但问题是“文本的中心”与我给出的位置不符,我有什么方法可以做后者。我已经对这个主题进行了很多搜索,但是找不到任何答案。请帮忙。
提前谢谢

您需要在绘图实例上设置对齐方式:
paint.setTextAlign(Paint.Align.CENTER);
在绘图之前。
修改强> 根据你的指示,你也喜欢它垂直居中,我会采用类似的方法:
paint.setColor(Color.WHITE);
paint.setTextAlign(Align.LEFT);
String text = "Hello";
Rect bounds = new Rect();
float x = 100, y = 100;
paint.getTextBounds(text, 0, text.length(), bounds); // Measure the text
canvas.drawLine(0, y, canvas.getWidth(), y, paint); // Included to show vertical alignment
canvas.drawLine(x, 0, x, canvas.getHeight(), paint); // Included to show horizsontal alignment
canvas.drawText(text, x - bounds.width() * 0.5f, y + bounds.height() * 0.5f, paint); // Draw the text
或者,使用油漆上的中心对齐:
paint.setColor(Color.WHITE);
paint.setTextAlign(Align.CENTER);
String text = "Hello";
Rect bounds = new Rect();
float x = 100, y = 100;
paint.getTextBounds(text, 0, text.length(), bounds); // Measure the text
canvas.drawLine(0, y, canvas.getWidth(), y, paint); // Included to show vertical alignment
canvas.drawLine(x, 0, x, canvas.getHeight(), paint); // Included to show horizsontal alignment
canvas.drawText(text, x, y + bounds.height() * 0.5f, paint); // Draw the text
