本文详细解析了Android开发中LinearLayout布局的Gravity属性与Layout_Gravity属性的作用及区别。Gravity属性用于控制子视图内部内容的对齐方式，而Layout_Gravity属性则决定了子视图在其父布局中的位置。

Some Android Developer may not know well of Linearlayout . This may help you to know sth about the gravity of its chilren;

-------------------CONET ------------------

1) wahts the diffrence between "gravity " android "layout_gravity"?

gravity: is sth to itself; this tell how you want its content to layout; Its see a TextView ; provided its wd is 200; and its content (text ) measured wd is 150; This Gravity setting will make its text align left ? top? center ? etc...

layout_gravity: is sth to its parent ; this tells it;s parent how it wants to be layed out; Again this TextView in its parent Linearlayout; Provided parent wd is 300, ht is 400;

2) WHY Does my layout_gravity not work?

layout_gravity is sth relevent to its parent orentation;

If its orentation is horizontal , top , btm , center_vertical will be effective;

else if is vertical : left , right ,center_horizontal is effective;
