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

Rect.intersects介绍

[英]Returns true if this rectangle intersects the specified rectangle. In no event is this rectangle modified. No check is performed to see if either rectangle is empty. To record the intersection, use intersect() or setIntersect().
[中]如果此矩形与指定矩形相交，则返回true。在任何情况下都不会修改此矩形。不执行任何检查以查看任一矩形是否为空。要记录交点，请使用intersect（）或setIntersect（）。

private void drawIcon(Canvas canvas, Drawable icon, Matrix iconMatrix) {
  canvas.save();
  canvas.concat(iconMatrix);
  // Drawing icon if it is within a visible part of the canvas
  canvas.getClipBounds(clipRect);
  final int width = icon.getIntrinsicWidth();
  final int height = icon.getIntrinsicHeight();
  if (clipRect.intersects(0, 0, width, height)) {
    icon.setBounds(0, 0, width, height);
    icon.draw(canvas);
  }
  canvas.restore();
}
