本文整理了Java中android.graphics.Rect.inset方法的一些代码示例，展示了Rect.inset的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Rect.inset方法的具体详情如下：
包路径：android.graphics.Rect
类名称：Rect
方法名：inset

Rect.inset介绍

[英]Inset the rectangle by (dx,dy). If dx is positive, then the sides are moved inwards, making the rectangle narrower. If dx is negative, then the sides are moved outwards, making the rectangle wider. The same holds true for dy and the top and bottom.
[中]按（dx，dy）插入矩形。如果dx为正，则两侧向内移动，使矩形变窄。如果dx为负，则边向外移动，使矩形变宽。dy、顶部和底部也是如此。

代码示例

Rect newRect = canvas.getClipBounds();
newRect.inset(-5, -5)  //make the rect larger

canvas.clipRect (newRect, Region.Op.REPLACE);
//happily draw outside the bound now

void init(View delegateView, Rect delegateBounds) {
 mDelegateView = delegateView;
 mSlop = ViewConfiguration.get(delegateView.getContext()).getScaledTouchSlop();
 mDelegateBounds.set(delegateBounds);
 mDelegateSlopBounds.set(delegateBounds);
 mDelegateSlopBounds.inset(-mSlop, -mSlop);
}

intersection.inset(horizontalMargin, verticalMargin);

intersection.inset(margin, margin);
if (intersection.height() > intersection.width()) {
  intersection.inset(0, (intersection.height() - intersection.width()) / 2);

@Override
 public void draw(Canvas canvas) {
  // We don't have access to the OverlayViewGroup instance directly, but we can manipulate
  // its Canvas via the Drawables' draw(). This allows us to draw outside the View bounds,
  // so we can position the margin overlays correctly.
  Rect newRect = canvas.getClipBounds();
  // Make the Canvas Rect bigger according to the View margins.
  newRect.inset(-(mMargins.right + mMargins.left), -(mMargins.top + mMargins.bottom));
  if (Build.VERSION.SDK_INT < Build.VERSION_CODES.O) {
   canvas.clipRect(newRect, Region.Op.REPLACE);
  } else {
   canvas.clipOutRect(newRect);
  }
  super.draw(canvas);
 }
}
