本文整理了Java中android.graphics.Rect.union方法的一些代码示例，展示了Rect.union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.union方法的具体详情如下：
包路径：android.graphics.Rect
类名称：Rect
方法名：union

Rect.union介绍

[英]Update this Rect to enclose itself and the [x,y] coordinate. There is no check to see that this rectangle is non-empty.
[中]更新此矩形以将其自身和[x，y]坐标围起来。无法检查此矩形是否为非空。

代码示例

代码示例来源：origin: jdamcd/android-crop

void moveBy(float dx, float dy) {
  Rect invalRect = new Rect(drawRect);
  cropRect.offset(dx, dy);
  // Put the cropping rectangle inside image rectangle
  cropRect.offset(
      Math.max(0, imageRect.left - cropRect.left),
      Math.max(0, imageRect.top  - cropRect.top));
  cropRect.offset(
      Math.min(0, imageRect.right  - cropRect.right),
      Math.min(0, imageRect.bottom - cropRect.bottom));
  drawRect = computeLayout();
  invalRect.union(drawRect);
  invalRect.inset(-(int) handleRadius, -(int) handleRadius);
  viewContext.invalidate(invalRect);
}
