Question

对应的类别:java.awt.Dimension对 and?

Answer 1

你们可以选择其中的一种选择:

<代码>android.util.Size(自A/60/821起)。它有getWidth()和getHala(),但指出其不可改变,即一旦创立,你可以修改(只创造新的、最新的例子)。
android.graphics.Rect。它有getWidth()和getHal(),但根据内部<代码>left、top、right、bottom<>/code>,并可能与其所有外变数和通用方法相混合。


android.graphics.Point which is a plain container, but the name is not right and it s main members are called x and y which isn t ideal for sizing.   However, this seems to be the class to use/abuse when getting display width and height from the Android framework itself as seen here:
Display display = getWindowManager().getDefaultDisplay();
Point size = new Point();
display.getSize(size);
int width = size.x;
int height = size.y;

Answer 2

您可使用rel=“nofollow”>code>Pair<Integer, Integer>, 系Anthony tuple阶层。 (需要替换getWidth()和getHala(>,first和second,但] 在安的安普兰小组的其他地方,似乎为此目的使用特设班级,例如 rel=“nofollow”>Camera.Size。

Answer 3

为什么你需要滥用其他班级,而不是像以下那样做:

public class Dimensions {

    public int width;
    public int height;

    public Dimensions() {}

    public Dimensions(int w, int h) {
        width = w;
        height = h;
    }

    public Dimensions(Dimensions p) {
        this.width = p.width;
        this.height = p.height;
    }

    public final void set(int w, int h) {
        width = w;
        height = h;
    }

    public final void set(Dimensions d) {
        this.width = d.width;
        this.height = d.height;
    }

    public final boolean equals(int w, int h) {
        return this.width == w && this.height == h;
    }

    public final boolean equals(Object o) {
        return o instanceof Dimensions && (o == this || equals(((Dimensions)o).width, ((Dimensions)o).height));
    }

}
