问题描述
当我实施
WindowManager wm = ((WindowManager)context.getSystemService(context.WINDOW_SERVICE));
Display display = wm.getDefaultDisplay();
m_nDisplayWidth = display.getWidth();
m_nDisplayHeight = display.getHeight();
我可以正常运行，但是当我实现 getSize 时，我得到 runtimeError
I can run fine, but when I implement getSize I get runtimeError
Point size = new Point();
display.getSize(size); //Error right here
m_nDisplayWidth = size.x;
m_nDisplayHeight = size.y;

推荐答案
这支持新旧设备:
private static Point getDisplaySize(final Display display) {
final Point point = new Point();
try {
display.getSize(point);
} catch (java.lang.NoSuchMethodError ignore) { // Older device
point.x = display.getWidth();
point.y = display.getHeight();
}
return point;
}
