推荐答案

我认为它可以为您提供帮助:

I think it could help you:

首先，您可以在xml中定义一个RelativeLayout，将所有需要的元素放在您想要的位置.

First you can define a RelativeLayout in xml, with all the elements you want on it, placed like you want.

第二，当您定义了该布局时，您可以开发一个自定义类，扩展RelativeLayout，然后在该类的构造函数方法中将该布局膨胀，如下所示:

Second, when you have that layout defined, you can develop a custom class, extending RelativeLayout, and inflate that layout in the constructor method of the class, something like this:

public class MyCustomView extends RelativeLayout {

 ...

 public MyCustomView(Context context) {

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

  addView(inflater.inflate(R.layout.your_layout, null));

  oneTextView = (TextView) findViewById(R.id.oneTextView);
  oneRadioButton = (RadioButton) findViewById(R.id.oneRadioButton);
  ...
 }
 ...
}

这时，您可以按常规方式在您的类中使用oneTextView，oneRadioButton等.

At this point, you can use oneTextView, oneRadioButton, etc., in your class in a normal way.
