A client-server flow always goes something like:
query from database -> (load from server -> save ->) display -> edit -> update.
With netframe, the flow above is all automatically set with very simple code, with no need to parse from JSON, display on views. You just need to specify fields with view ids, all the datas will be automatically displayed.
Netframe is based on ActiveAndroid, Gson, universal image loader and volley, which supports TextView, SpinnerView, ImageView, CheckBox and AbsListView now. ##sample code
In the sample code below, the activity does 4 things:
- query from database
- if get nothing from database, load data from server
- insert data into database
- display data, image included on the view
public class Demo3Activity extends Activity{
@Override
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
ImageLoader.getInstance().init(ImageLoaderConfiguration.createDefault(this));
UserBean bean = new UserBean();
bean.userName = "Dan";
Netframe.inject(this, new MutableEntity<UserBean>(bean));
}
}
@ActivityInj(R.layout.activity_demo2)
@Table(name = "User")
public class UserBean extends Entity implements Downloadable{
@ViewInj(R.id.user_portrait)
@Column(name = "portrait")
public String userPortrait;
@ViewInj(R.id.user_name)
@Column(name = "userName")
public String userName;
@ViewInj(R.id.email)
@Column(name = "email")
public String email;
@ViewInj(R.id.married)
@Column(name = "married")
public boolean married;
@ViewInj(R.id.number_list)
public List<Number> numbers;
public List<Number> numbers(){
return getMany(Number.class, "userBean");
}
public UserBean(){
super();
}
@Override
public Entity query() {
UserBean entity = new Select().from(UserBean.class)
.where("userName = ?", userName).executeSingle();
if(entity != null){
entity.numbers = entity.numbers();
}
return entity;
}
@Override
public String onDownLoadUrl(Context context) {
return MyApplication.URL + "netframe_get_user.php";
}
@Override
public void onDownLoadResponse(Context context) {
// TODO Auto-generated method stub
}
@Override
public Object onDownloadParams() {
HashMap<String, String> params = new HashMap<String, String>();
params.put("userName", userName);
return params;
}
}
@GroupViewInj(R.layout.layout_number)
@Table(name = "Number")
public class Number extends Entity{
public Number(){
super();
}
@ViewInj(R.id.contact_number)
@Column(name = "number")
public String number;
@Column(name = "userBean")
public UserBean user;
@Override
public Entity query() {
// TODO Auto-generated method stub
return null;
}
@Override
public void setForignKey(Entity entity) {
user = (UserBean) entity;
}
}First, extend NetframeApplication
public class MyApplication extends NetframeApplication
Second, edit your manifest
<uses-permission android:name="android.permission.INTERNET"/>
<application
android:name="sample.MyApplication"
... >
<meta-data android:name="AA_DB_NAME" android:value="netframe.db" />
<meta-data android:name="AA_DB_VERSION" android:value="5" />That's it!
