Android：如何创建这种动态布局？

Question

My aim is to display people/addresses in a list - but not just a simple list, rather a list of boxes that contain several information, in my case a number, the address and a type:

The data structure for this are POJOs:

• MyPojo.java (Class)
• + getNumer()
• + getType()
• + getName()
• + getStreet()
• + getCity()

Of course, there are more than 4 entries which means that there should be a scrollbar. My first idea: a Scrollview that contains a Linear Layout . But I'm not sure about the content, means the boxes you can see above.

1. How can I define such boxes that represent the list items? As you can see above, a box consists of three parts that are divided from each other (Number, Type, Address).
2. Of course, it must be possible to add and remove boxes (means: entries) dynamically at runtime to the Linear Layout.

Thank you

My first idea: a Scrollview that contains a Linear Layout.

Are you familiar with a listView ? This already exists to do exactly that. I'm sure you can find dozens of tutorials on how to use them by searching.

• Create a ListActivity class

• Create a separate layout file for your item

  <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="horizontal" > <LinearLayout android:orientation="vertical" > <TextView /> <TextView /> </LinearLayout> </TextView> </LinearLayout>

• Then Create an inner class in ListActivity which extends from ArrayAdapter . In the getView() method, use LayoutInflater to inflate yourItemLayout and update the TextView based on the position values.
• From onCreate in the main class, call setListAdapter(new InnerClass(this,R.layout.yourItemLayout,list)

You can refer customArrayAdapter to know how to custom ArrayAdapter works.

Done and dusted.
