| ↳ | android.hardware.Camera.Size |
该类在API级别21中已被弃用。
我们建议将新的android.hardware.camera2 API用于新应用程序。

Android开发手册
Camera.Size (int w,
int h)
设置图片的尺寸。
| Parameters | |
|---|---|
w |
int: the photo width (pixels) |
h |
int: the photo height (pixels) |
boolean equals (Object obj)
将 obj与此大小比较。
| Parameters | |
|---|---|
obj |
Object: the object to compare this size with. |
| Returns | |
|---|---|
boolean |
true if the width and height of obj is the same as those of this size. false otherwise. |
int hashCode ()
返回对象的哈希码值。 为了散列表的好处而支持该方法，例如由HashMap提供的HashMap 。
hashCode的总合同是：
hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application. equals(Object) method, then calling the hashCode method on each of the two objects must produce the same integer result. equals(java.lang.Object) method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables. 尽可能合理实用，类Object定义的hashCode方法确实为不同的对象返回不同的整数。 （这通常通过将对象的内部地址转换为整数来实现，但Java TM编程语言不需要此实现技术。）

a hash code value for this object. |
