有谁知道如何在Android中实现自定义布局？

Does anyone know how to implement custom layouts in android?

我有CustomLayout类。

I have CustomLayout class.

CustomLayout extends LinearLayout

与构造公共CustomLayout（上下文的背景下）和公共CustomLayout（上下文的背景下，AttributeSet中的ATTRS）

我也有一个XML布局（的example.xml）

I also have a xml layout (example.xml)

<com.myproject.layout.CustomLayout 
    android:id="@+id/cl_main"    
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical">

   <Button
    android:id="@+id/button1"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="inside button" />

</com.myproject.layout.CustomLayout>

当我设置的内容视图中我的活动

When I set the content view in my activity

    setContentView(R.layout.example);

我的全球布局是膨胀并显示，但内键是不是里面的布置... 任何想法？

My Global layout is inflated and is showed, but the "inner button" is not inside the layout... Any ideas?

推荐答案

我发现你必须重写此方法。

I found that you must override this method.

public void addView(View child, android.view.ViewGroup.LayoutParams params)
{
    //... 
    llContainer.addView(child, fillParentLayoutParams);
    //...
}

其中llContainer是其中次应该放置的布局。 这种方法被充气来填充你的视图的XML定义。

where llContainer is the layout where the views should be placed. this method is called by the inflater to populate your view with the xml definitions.
