I've got and idea on how to create custom control here: Android interface - need suggestions on what widgets to use

我如何做相同的，但在创建XML控件的布局，只是夸大它在code？不喜欢在这个例子中，我必须手动创建每个控件。

How do I make the SAME but creating control's layout in XML and just inflating it in code? Not like in this example where I have to create each control manually.

我的第一个问题的LinearLayout是用作基础不支持的setView（）命令。如果我向其他什么东西？

My first problem that LinearLayout that used as a base does not support setView() command. Should I extend something else?

编辑：我发现 本： <一href="http://developer.android.com/guide/topics/ui/custom-components.html">http://developer.android.com/guide/topics/ui/custom-components.html 和这个： <一href="http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/view/List4.html">http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/view/List4.html

I found This: http://developer.android.com/guide/topics/ui/custom-components.html and this: http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/view/List4.html

好像我需要的复合控制。我只需要code点点。我如何从充气XML控件的内容？无论文章和样品说我可以，但怎么样？

Seems like I need COMPOUND CONTROL. I just need little bit of code. How do I inflate control's content from XML? BOth article and sample say I can but HOW?

推荐答案

您必须使用的布局是这样的：

You have to use a layout like this:

<?xml version="1.0" encoding="utf-8"?>
<merge xmlns:android="http://schemas.android.com/apk/res/android">
  <View android:layout_width="fill_parent"
  android:layout_height="0px"
  android:layout_weight="1"
  android:background="#0F0"/>
  <View android:layout_width="fill_parent"
  android:layout_height="0px"
  android:layout_weight="1"
  android:background="#0FF"/>
</merge>

其中，＆LT;合并＆GT; 的意思是把一切的我内心到父我将充气至

where <merge> means "put everything that's inside me into the parent I'm going to be inflated to".

然后在code：

public class CControl extends LinearLayout {

    public CControl(Context context) {
        this(context, null);
    }

    public CControl(Context context, AttributeSet attrs) {
        super(context, attrs);

        LayoutInflater inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

        inflater.inflate(R.layout.tryout, this);
    }
    // ......
}

在这一点上，你可以用你的复合控制，就好像它是一个LinearLayout中，所以你必须要在外部布局指定，如果你希望它是垂直的，例如，或者你可以将其设置为内部的默认构造函数。

At this point you can use your compound control as if it's a LinearLayout, so you'll have to specify in the outer layout if you want it to be vertical, for example, or you could set it as a default inside the constructor.
