通知栏的高度获取

通过反射机制获取通知栏高度

通知栏高度写在dimen文件中

public static int getStatusBarHeight(Context context){
        Class<?> c = null ;
        Object obj = null ;
        Field field = null ;
        int x = 0 , statusBarHeight = 0 ;
        try {
            c = Class.forName( "com.android.internal.R$dimen" );
            obj = c.newInstance();
            field = c.getField( "status_bar_height" );
            x = Integer.parseInt(field.get(obj).toString());
            statusBarHeight = context.getResources().getDimensionPixelSize(x);
        } catch (Exception e1) {
            e1.printStackTrace();
        }
        return statusBarHeight;
   }
