I am new to android development and keep coming across references to Inflating views from a layout xml file. I googled and searched the development guide but still wasn't able to pick up a sense for what it means. If someone could provide a very simple example, it'd be much appreciated.

推荐答案

当你写了一个XML布局，这将是充气的由Android操作系统这基本上意味着它会被渲染。让我们调用的隐性通胀的（操作系统将膨胀认为你）。例如：

When you write an XML layout, it will be inflated by the Android OS which basically means that it will be rendered. Let's call that implicit inflation (the OS will inflate the view for you). For instance:

class Name extends Activity{
    public void onCreate(){
         // the OS will inflate the your_layout.xml
         // file and use it for this activity
         setContentView(R.layout.your_layout);
    }
}

您也可以明确使用 LayoutInflater 膨胀的看法。在这种情况下，你必须：

You can also inflate views explicitly by using the LayoutInflater. In that case you have to:

1. 获得 LayoutInflater
的实例
2. 指定的XML膨胀
3. 使用返回查看

1. Get an instance of the LayoutInflater
2. Specify the XML to inflate
3. Use the returned View

例如：

LayoutInflater inflater = LayoutInflater.from(YourActivity.this); // 1
View theInflatedView = inflater.inflate(R.layout.your_layout, null); // 2 and 3
