android – 可用屏幕的大小

如果所有的方块都在同​​一个ImageView中,那么我猜最简单的方法是创建自己的imageView：

class MyImageView extends ImageView {
    Context context;
    int myWidth = 0;
    int myHeigh = 0;
    int numBoxesX = 0;
    int numBoxesY = 0;

    private final int BoxWidth  = 30;
    private final int BoxHeight = 30;

    ImageView(Context C) {
        super(c);
        context = c;
    }
}

在类中,您重写onSizeChange函数

@Override
protected void onSizeChanged (int w,int h,int oldw,int oldh) {
    super.onSizeChanged(w,h,oldw,oldh);
    myWidth  = w;
    myHeight = h;
    // Set up other things that you work out from the width and height here,such as

    numBoxesX = myWidth / BoxWidth;
    numBoxesY = myHeight / BoxHeight;
}

然后创建一个绘制框的函数：

public void drawSubBox(int x,int y,...) {
    // Fail silently if the Box being drawn doesn't exist ...
    if ((x<0) || (x>=numBoxesX)) return;
    if ((y<0) || (y>=numBoxesY)) return;

    // Your code to draw the Box on the screen ...
}

创建此视图后,您可以将其添加到布局中,并像访问任何其他视图一样访问它的功能,包括您添加的任何内容以定义子框的大小等等.因此,在此类的活动中使用此布局

@H_89_31@myImageView miv; miv = topView.findViewById("idforMyImageViewSeTinLayoutXMLfile"); miv.drawSubBox(0,...);
