Finalactivity

Finalactivity is a basic class, with annotations implemented, Dependency injection (view resource ID, Common listener), using set method to inject

UI binding and event binding can be done in a fully annotated manner without the need for Findviewbyid and set event Listener

This process: Initinjectedview>findviewbyid, Setlistener (activity, Activity.field, Eventlocalmethod, EventType) >

1. Get the View object according to the ID, set to the field in the activity corresponding

2. Switch (eventtype) {

Case event:

View.set Event Listener (new EventListener (activity, Eventlocalmethod));

EventListener implements many event listener>

In the overridden method of the corresponding event, the reflection call Eventlocalmethod

The parameters of these eventlocalmethod need to be consistent with the parameters of the corresponding system event method

...

}

What types of annotations are available:

@Target (Elementtype.field) @Retention (retentionpolicy.runtime) public @interface viewinject {public int id ();p ublic String click () Default "";p ublic string Longclick () default "";p ublic string ItemClick () default "";p ublic string Itemlong Click () Default "";p ublic Select Select () Default @Select (selected= "");}

Invoke Annotations:

Package Com.stone.afinal;import Net.tsz.afinal.finalactivity;import Net.tsz.afinal.annotation.view.select;import Net.tsz.afinal.annotation.view.viewinject;import Android.os.bundle;import Android.view.view;import Android.widget.adapterview;import Android.widget.imageview;import Android.widget.listview;public Class Mainactivity extends Finalactivity {@ViewInject (id = r.id.imageview, click = "Myclick", Longclick = "Mylongclick") ImageView ImageView; @ViewInject (id = r.id.listview, click = "Myclick", Itemlongclick = "Myitemlongclick", ItemClick = " Myitemclick ", Longclick =" Mylongclick ", select = @Select (selected=" myitemselected ", noselected=" mynoselected ")) ListView listview; @Overrideprotected void OnCreate (Bundle savedinstancestate) {super.oncreate (savedinstancestate); Setcontentview (R.layout.main);//inherited Finalactivity,setcontentview initialized in} public void Myclick (View v) { System.out.println ("--myclick--");} public void Mylongclick (View v) {System.out.println ("--mylongclick--");} public void MyitemlongclicK (adapterview<?> arg0, View arg1, int arg2,long arg3) {System.out.println ("--myitemlongclick--");} public void Myitemclick (adapterview<?> arg0, View arg1, int arg2, long arg3) {System.out.println ("--myitemclick--" );} public void myitemselected (adapterview<?> arg0, View arg1, int arg2,long arg3) {System.out.println ("-- myitemselected--");} public void mynoselected (adapterview<?> arg0) {System.out.println ("--mynoselected--");}}

Used in other intrusive frameworks (e.g. Actionbarshelock)

     protected void onCreate(Bundle savedinstancestate) {       Super.onCreate(savedinstancestate);        Setcontentview(View);        finalactivity.Initinjectedview( This);     }

Use in Fragment

      Public View Oncreateview(Layoutinflater Inflater, ViewGroup Container,          Bundle savedinstancestate) {       View Viewroot = Inflater.Inflate(R.Layout.Map_frame, Container, false);       finalactivity.Initinjectedview( This,Viewroot);    }
