获取状态栏的高度。

private static int statusBarHeight;

private int getStatusBarHeight() {
if (statusBarHeight == 0) {
try {
Class<?> c = Class.forName("com.android.internal.R$dimen");
Object o = c.newInstance();
Field field = c.getField("status_bar_height");
int x = (Integer) field.get(o);
statusBarHeight = getResources().getDimensionPixelSize(x);
} catch (Exception e) {
e.printStackTrace();
}
}
return statusBarHeight;
}

获取屏幕的宽和高

方法一：

WindowManager mWm = (WindowManager) getSystemService(WINDOW_SERVICE);
int screenWidth = mWm.getDefaultDisplay().getWidth();
int screenHeight = mWm.getDefaultDisplay().getHeight();

注意：getWidth()和getHeight()方法已经过时

方法二：

WindowManager mWm = (WindowManager) getSystemService(WINDOW_SERVICE);
Point point= new Point();
mWm.getDefaultDisplay().getRealSize(point);
int screenWidth=point.x;
int screenHeight=point.y;
