AndroidAnnotations——Listening to AdapterViewEvents监听适配器视图事件

AdapterViewEvents适配器视图事件

Since AndroidAnnotations 1.0

You can bind methods to handle events on items in an AdapterView:

你可以绑定方法来处理适配器视图中项目的事件：

Item clicks with

@ItemClick

Long item clicks with

@ItemLongClick

Item selection with

@ItemSelect

Methods annotated with

@ItemClick

or

@ItemLongClick

must
have one parameter. This parameter can be of any type, it's the object retrieved when calling

adapter.getItem(position)

.
加了

@ItemClick

和

@ItemLongClick

注解的方法必须有一个参数。这个参数可以是任何类型的，调用

adapter.getItem(position)

时返回一个object对象。

Methods annotated with

@ItemSelect

may
have one or two parameters. The first parameter must be a boolean, and the second is the object from the adapter, at the selected position.
加了

@ItemSelect

注解的方法可能有一个或两个参数。第一个参数必须是boolean类型，第二个参数是适配器中被选位置的对象。

@EActivity(R.layout.my_list)
public class MyListActivity extends Activity {

// ...

@ItemClick
public void myListItemClicked(MyItem clickedItem) {

}

@ItemLongClick
public void myListItemLongClicked(MyItem clickedItem) {

}

@ItemSelect
public void myListItemSelected(boolean selected, MyItem selectedItem) {

}

}

Since AndroidAnnotations 2.4
For

@ItemClick

,

@ItemLongClick

and

@ItemSelect

,
if the parameter is of type

int

, then the position is
given instead of the object coming from the adapter.
对于

@ItemClick

,

@ItemLongClick

和

@ItemSelect

来说，如果参数是

int

类型的，那么适配器将传送位置值代替对象值。

@EActivity(R.layout.my_list)
public class MyListActivity extends Activity {

// ...

@ItemClick
public void myListItemClicked(int position) {

}

@ItemLongClick
public void myListItemLongClicked(int position) {

}

@ItemSelect
public void myListItemSelected(boolean selected, int position) {

}

}
