Java 使用xml创建视图与使用代码创建视图之间的区别
当我试图以编程方式添加RelativeLayout时，与直接使用xml视图时，两者有所不同 如果我在容器中复制粘贴多个RelativeLayout，它会工作 当我尝试膨胀一个relativeLayout文件（与进入容器选项卡完全相同）时，结果是不同的，它不起作用 如何以编程方式填充视图Java 使用xml创建视图与使用代码创建视图之间的区别,java,android,android-layout,Java,Android,Android Layout,当我试图以编程方式添加RelativeLayout时，与直接使用xml视图时，两者有所不同 如果我在容器中复制粘贴多个RelativeLayout，它会工作 当我尝试膨胀一个relativeLayout文件（与进入容器选项卡完全相同）时，结果是不同的，它不起作用 如何以编程方式填充视图 @BindView(R.id.container_tabs) protected LinearLayout mLinearLayoutContainerTabs; private Lis

有什么好办法吗？有什么问题吗？从XML添加视图和从结构上膨胀视图有一些区别 但是在相对布局的情况下，当您准备XML时，有太多的相对属性用于将不同的视图一起设置为XML 当我们使用相对布局动态添加视图时，我们应该使用ADDRULE选项，如下面所示：
RelativeLayout relativeLayout = new RelativeLayout(getActivity());
RelativeLayout.LayoutParams layoutParams = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT);
Button button1 = new Button(this);
button1.setId(1);
Button button2 = new Button(this);
button2.setId(2);
relativeLayout.addView(button1);
relativeLayout.addView(button2);
RelativeLayout.LayoutParams lp = (RelativeLayout.LayoutParams) button1.getLayoutParams();
lp.addRule(RelativeLayout.RIGHT_OF, button2.getId());
lp.addRule(RelativeLayout.LEFT_OF, button2.getId());
lp.addRule(RelativeLayout.ALIGN_END, button2.getId());
lp.addRule(RelativeLayout.ALIGN_LEFT, button2.getId());
lp.addRule(RelativeLayout.ALIGN_BASELINE, button2.getId());
lp.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM, button2.getId());
lp.addRule(RelativeLayout.ALIGN_PARENT_LEFT, button2.getId());
lp.addRule(RelativeLayout.ALIGN_PARENT_RIGHT, button2.getId());
lp.addRule(RelativeLayout.ABOVE, button2.getId());
lp.addRule(RelativeLayout.ALIGN_PARENT_TOP, button2.getId());
lp.addRule(RelativeLayout.START_OF, button2.getId());
lp.addRule(RelativeLayout.ALIGN_RIGHT, button2.getId());
lp.addRule(RelativeLayout.ALIGN_PARENT_END, button2.getId());
lp.addRule(RelativeLayout.END_OF, button2.getId());
几乎所有相关的布局属性都可以通过AddRull动态添加。从XML添加视图和从结构上膨胀视图有一些不同 但是在相对布局的情况下，当您准备XML时，有太多的相对属性用于将不同的视图一起设置为XML 当我们使用相对布局动态添加视图时，我们应该使用ADDRULE选项，如下面所示：
