Android视图不像LayOut我设计？

Question

我是Android开发的初学者，我使用Android studio创建了示例视图。但是当我运行时没有给出正确的put.please时，请参考下面的图片。

我创建我的主页LayOut作为右图。但是当我运行Come View Like Left Hand Picture.I运行不同的模拟器但输出是相同的。请希望得到一些专家的帮助。

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
