Android的：如何用2布局 [英] Android: How to use 2 layout

问题描述

我试图做一个应用程序，其中有一个背景，并用帆布我画一些线条。但是有一个问题。由于制作背景等graphicals事情，我使用，并命名为activity_main.xml一个.xml文件后，我做的       的setContentView（R.layout.activity_main）; 来激活它。但是，当我划清界线，我必须这样做：

I'm trying to do an application where there is a background, and with canvas i draw some lines. But there is a problem. Because to make background and other graphicals things i use a .xml file named "activity_main.xml" and after i do setContentView(R.layout.activity_main); to activate it. But when i draw the line i must use this:

 drawView = new DrawView(this) 
 setContentView(drawView);

在哪里drawView函数的类，它让我划清界线。 所以第一的setContentView结果没用，我不知道该怎么做了一些变化（例子背景），如果我与drawView函数工作！

Where drawView is the class that allow me to draw the line. So the first setContentView result useless and i don't know how to do some change (for examples the background) if i had to work with drawView!

你有没有办法添加drawView函数在activity_main布局？ 对不起，我想是的，但我不知道该怎么办。

"You have no way to add a DrawView in your activity_main layout ?" Sorry, i suppose yes, but i don't know how to do.

推荐答案

您可以将您的视角以这样的布局：

You can add your view to your layout like this:

ViewGroup layout = (ViewGroup) findViewById(R.id.your_layout_id);//your container's id in your activity_main.xml 
drawView = new DrawView(this); 
layout.addView(drawView);
