blocks|key|1792496|text|适配器基本上用于传递内容。您可能在每个应用程序中都有一个适配器，即CursorAdapter，它使您能够交付由数据库查询中的游标提供的内容。ListView几乎总是有某种类型的适配器。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1792497|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Adapters are basically used to deliver content. One adapter you probably have in every application is the CursorAdapter which enables you to deliver content given by a cursor from a database query. A ListView has nearly always some sort of Adapter.

blocks|key|1792572|text|Android中的适配器基本上是UI组件和将数据填充到UI组件中的数据源之间的桥梁|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1792573|例如，使用列表适配器从数据源数组填充列表(UI组件)。|1792574|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

Well adapters in Android are basically a bridge between the UI components and the data source that fill data into the UI Component

For example, Lists (UI Component) get populated by using a list adapter, from a data source array.

blocks|key|1792688|text|适配器充当AdapterView和该视图的底层数据之间的桥梁。适配器提供对数据项的访问，并负责为数据集中的每个项创建视图。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1792689|适配器是连接View和某种数据源的一种智能方法。通常，您的视图将是ListView，数据将以Cursor或Array的形式出现。因此，适配器是作为CursorAdapter或ArrayAdapter的子类出现的。|1792690|entityMap^0|5|B|0|6|4|X|8|1A|6|1H|5|21|D|2F|C|0^^$0|@$1|2|3|4|5|6|7|J|8|@$9|K|A|L|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|M|8|@$9|N|A|O|B|C]|$9|P|A|Q|B|C]|$9|R|A|S|B|C]|$9|T|A|U|B|C]|$9|V|A|W|B|C]|$9|X|A|Y|B|C]]|D|@]|E|$]]|$1|H|3|-4|5|6|7|Z|8|@]|D|@]|E|$]]]|I|$]]

An adapter acts as a bridge between an <code>AdapterView</code> and the underlying data for that view.
The adapter provides access to the data items and is responsible for creating a view for each item in the data set.

Adapters are a smart way to connect a <code>View</code> with some kind of data source. Typically, your view would be a <code>ListView</code> and the data would come in form of a <code>Cursor</code> or <code>Array</code>.
So adapters come as subclasses of <code>CursorAdapter</code> or <code>ArrayAdapter</code>.

blocks|key|2006465|text|适配器管理数据模型并使其适应列表视图中的各个行。它扩展了BaseAdapter类。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|2006466|列表视图中的每一行都由一个布局组成，布局可以根据您的需要而复杂。列表视图中的典型行在左侧有一幅图像，中间有两行文本。|2006467|entityMap^0|S|B|0|0^^$0|@$1|2|3|4|5|6|7|J|8|@$9|K|A|L|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|M|8|@]|D|@]|E|$]]|$1|H|3|-4|5|6|7|N|8|@]|D|@]|E|$]]]|I|$]]

An adapter manages the data model and adapts it to the individual rows in the list view.
It extends the <code>BaseAdapter</code> class.

Every line in the list view consists of a layout which can be as complex as you want.
A typical line in a list view has an image on the left side and two text lines in the middle.

blocks|key|2006603|text|适配器只是用来实现列表视图的概念。不仅用于显示数据列表，还用于显示一些自定义视图。假设客户想要使用有更多文本视图(任何其他视图)的列表，那么我们必须在Android中使用Adapter视图。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2006604|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Adapter is simply used to achieve the listview concept. Not only for displaying the list of data but also the some custom view. Suppose customer wants to use the list which has more number of textview (any other view) then , we have to use Adapter view in Android.

blocks|key|1792942|text|最后，适配器对于生成报告非常有用。如果想要显示某些信息的报表，可以使用此工具在视图上显示数据。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1792943|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

At the end, adapters are very useful to do a report. If one wants to show a report of some information, one can use this tool to show the data on the view.

I want to know when, where and how adapters are used in the context of Android.

The information from Android's developer documentation was insufficient for me and I'd like to get a more detailed analysis.

What's the role of adapters in Android?
