在Android中绘制矩形并在它们之间留有空间

我想在Android中绘制五个矩形条。我有矩形，但现在我希望它们之间有一点间隔。

我希望它们在底部对齐，并且它们之间的距离相同。

for (int i= 0; i<4; i++) {
int ce = heigth[i];

Paint rectanglePaint = new Paint(); 
rectanglePaint.setARGB(255, 0, 0, 0); 
rectanglePaint.setStrokeWidth(2);
rectanglePaint.setColor(Color.BLUE);
rectanglePaint.setStyle(Style.STROKE);

Rect rectangle = new Rect(35+10*ce, 150, 10, 10*ce); //in pixels
//rectangle.offset(50, 50);
rectangle.offsetTo(55+10*ce, 150);
//canvas.translate(10, 0); 
canvas.drawRect(rectangle, rectanglePaint);

我尝试过 offset、offsetTo、translate，但找不到使用它们的逻辑。我希望它们都从不同的位置开始，比如它们向右移动 35 度，宽度都为 30 度。虽然我在左边添加了35，但它们仍然来自同一个位置。

I want to draw five rectangle bars in Android. I have the regtangles, but now I want them to be a bit spaced apart.

I want them to be aligned at the bottom, and with the same distance between them.

for (int i= 0; i<4; i++) {
int ce = heigth[i];

Paint rectanglePaint = new Paint(); 
rectanglePaint.setARGB(255, 0, 0, 0); 
rectanglePaint.setStrokeWidth(2);
rectanglePaint.setColor(Color.BLUE);
rectanglePaint.setStyle(Style.STROKE);

Rect rectangle = new Rect(35+10*ce, 150, 10, 10*ce); //in pixels
//rectangle.offset(50, 50);
rectangle.offsetTo(55+10*ce, 150);
//canvas.translate(10, 0); 
canvas.drawRect(rectangle, rectanglePaint);

I have tried with offset, offsetTo, translate, but can't find the logic in using them. I want them all to start at different spots, like they move 35 dip to the right and are all 30 dip wide. Although I add 35 to the left, they still originate from the same spot.

也许 height[i] 不会改变？

这应该创建四个 10x10 矩形，彼此左侧间隔 35 像素。顺便说一句，您不需要创建四个 Paint 对象。对四个矩形重复使用相同的内容以提高效率。

Paint rectanglePaint = new Paint(); 
rectanglePaint.setARGB(255, 0, 0, 0); 
rectanglePaint.setStrokeWidth(2);
rectanglePaint.setColor(Color.BLUE);
rectanglePaint.setStyle(Style.STROKE);

for (int i= 0; i<4; i++) {
  Rect rectangle = new Rect(35*i, 150, 35*i+10, 160);
  canvas.drawRect(rectangle, rectanglePaint);
}

Perhaps height[i] do not change?

Thisn should create four 10x10 rectangles separated 35 px to the left each other. BTW, you do not need to create four Paint objects. Reuse the same for the four rectangles for improved efficiency.

Paint rectanglePaint = new Paint(); 
rectanglePaint.setARGB(255, 0, 0, 0); 
rectanglePaint.setStrokeWidth(2);
rectanglePaint.setColor(Color.BLUE);
rectanglePaint.setStyle(Style.STROKE);

for (int i= 0; i<4; i++) {
  Rect rectangle = new Rect(35*i, 150, 35*i+10, 160);
  canvas.drawRect(rectangle, rectanglePaint);
}
