Android编程实现获得手机屏幕真实宽高的方法

本文实例讲述了android编程实现获得手机屏幕真实宽高的方法。分享给大家供大家参考，具体如下：

windowmanager w = activity.getwindowmanager();
display d = w.getdefaultdisplay();
displaymetrics metrics = new displaymetrics();
d.getmetrics(metrics);
// since sdk_int = 1;
widthpixels = metrics.widthpixels;
heightpixels = metrics.heightpixels;
try {
  // used when 17 > sdk_int >= 14; includes window decorations (statusbar bar/menu bar)
  widthpixels = (integer) display.class.getmethod("getrawwidth").invoke(d);
  heightpixels = (integer) display.class.getmethod("getrawheight").invoke(d);
} catch (exception ignored) {
}
try {
  // used when sdk_int >= 17; includes window decorations (statusbar bar/menu bar)
  point realsize = new point();
  display.class.getmethod("getrealsize", point.class).invoke(d, realsize);
  widthpixels = realsize.x;
  heightpixels = realsize.y;
} catch (exception ignored) {
}

补:改进版 (弥补了原先非支持版本的一些异常):

windowmanager w = activity.getwindowmanager();
display d = w.getdefaultdisplay();
displaymetrics metrics = new displaymetrics();
d.getmetrics(metrics);
// since sdk_int = 1;
widthpixels = metrics.widthpixels;
heightpixels = metrics.heightpixels;
// includes window decorations (statusbar bar/menu bar)
if (build.version.sdk_int >= 14 && build.version.sdk_int < 17)
try {
  widthpixels = (integer) display.class.getmethod("getrawwidth").invoke(d);
  heightpixels = (integer) display.class.getmethod("getrawheight").invoke(d);
} catch (exception ignored) {
}
// includes window decorations (statusbar bar/menu bar)
if (build.version.sdk_int >= 17)
try {
  point realsize = new point();
  display.class.getmethod("getrealsize", point.class).invoke(d, realsize);
  widthpixels = realsize.x;
  heightpixels = realsize.y;
} catch (exception ignored) {
}

希望本文所述对大家android程序设计有所帮助。
