Android一些设备都有上下两条bar，我们可以获取这些bar的信息。 原文地址：http://www.cnblogs.com/rossoneri/p/4142962.html
获取顶部status bar 高度
private int getStatusBarHeight() {
Resources resources = mActivity.getResources();
int resourceId = resources.getIdentifier("status_bar_height", "dimen","android");
int height = resources.getDimensionPixelSize(resourceId);
Log.v("dbw", "Status height:" + height);
return height;
}
获取底部 navigation bar 高度
private int getNavigationBarHeight() {
Resources resources = mActivity.getResources();
int resourceId = resources.getIdentifier("navigation_bar_height","dimen", "android");
int height = resources.getDimensionPixelSize(resourceId);
Log.v("dbw", "Navi height:" + height);
return height;
}
