a data-mediator framework which uses annotation processing to generate boilerplate code for you.

Features

  • 1, Auto generate 'data-impl' and 'data-proxy' (use plugin to generare methods of 'data-module'). support listen property change, Detail
  • 2, auto generate get/is/set, hashCode, equals,toString method.
  • 3, support chain call. Detail
  • 4, support impl Serializable and parcelable(android). or others. Detail
  • 5, full support Annotations of Google/Gson. Detail
  • 6, support self method. self field. extend self interface you like. Detail
  • 7, support data cache. Detail
  • 8, support List/SparseArray Editor with their callbacks. Detail

  • 10, Full support Data-binding on android.
  • 11, full support data-binding in adapter which Can Best Seamless with 'butterknife'.
 public class InnerViewHolder extends DataBindingRecyclerAdapter.DataBindingViewHolder<Student>{

        @BindView(R.id.tv_name) @BindText("name")
        TextView mTv_name;

        @BindView(R.id.tv_age) @BindText("age")
        TextView mTv_age;

        public InnerViewHolder(View itemView) {
            super(itemView);
        }

        @Override
        protected void onPreCreateDataBinding(View itemView) {
            ButterKnife.bind(this, itemView);
        }

        @OnClick(R.id.tv_name)
        public void onClickName(View v){
            //here just toast
            Toast.makeText(v.getContext(), "onClickName is called, pos = "
                    + getAdapterPosition2(), Toast.LENGTH_SHORT).show();
        }
        @OnClick(R.id.tv_age)
        public void onClickAge(View v){
            //here just toast
            Toast.makeText(v.getContext(), "onClickAge is called, pos = "
                    + getAdapterPosition2(), Toast.LENGTH_SHORT).show();
        }
        @OnClick(R.id.bt_change_item)
        public void onClickChangeItem(View v){
            final int pos = getAdapterPosition2();
            getDataProxy()
                    .setAge((int) (System.currentTimeMillis() % 99))
                    .setId(pos)
                    .setName("google+__" + pos);
            //Note: no need notifyItemChanged here.
        }
    }
  • 12, support bind property chain. like '@BindBackground("viewBind.background")'. actual demo like this:
public class SimplePropertyChainActivity extends BaseActivity {

    //'viewBind' is a property name of RootModule.
    @BindView(R.id.v_bg) @BindBackground("viewBind.background")
    View mV_bg;

//.............more views

    private ResHelper mHelper = new ResHelper();
    private Binder<RootModule> rootBinder;
    private DataMediator<ViewBind> dm_viewBind;

    @Override
    protected int getLayoutId() {
        return R.layout.ac_test_view_bind;
    }
    @Override
    protected void onInit(Context context, Bundle savedInstanceState) {
        mHelper.init(context);

        RootModule rootModule = DataMediatorFactory.createData(RootModule.class);
        rootModule.setViewBind(DataMediatorFactory.createData(ViewBind.class));

        //bind data.
        rootBinder = DataMediatorFactory.bind(this, rootModule);
        dm_viewBind = DataMediatorFactory.createDataMediator(
                rootBinder.getDataMediator(), rootModule.getViewBind());
    }

    @OnClick(R.id.bt_change_bg)
    public void onClickChangeBg(View v){
        //change bg(drawable)
        dm_viewBind.getDataProxy().setBackground(mHelper.toggleDrawable());
    }
    //.............
    
}

       }
    }
    • 2, idea setting

      • (1), setting -> compiler -> annotation Processor -> 勾选  more to see idea
      • (2), set generate dir to the source/test source dir.
    • 3, add dependencies.

    dependencies {
      compile 'com.heaven7.java.data.mediator.annotation:data-mediator-annotations:<see release>'
      compile 'com.heaven7.java.data.mediator.support.gson:data-mediator-support-gson:<see release>'
    
      compile 'com.heaven7.java.data.mediator:data-mediator:<see release>'
      apt 'com.heaven7.java.data.mediator.compiler:data-mediator-compiler:<see release>'
      apt 'com.squareup:javapoet:1.9.0'
    }
  • android platform ( for android project) .
    • if you use old gradle version lower of 4.1. such as: '3.5'
      • 1, in the root build file。
       classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'
      • 2, in app module add apt plugin
         apply plugin: 'com.neenbedankt.android-apt'
      • 3, add dependencies
      dependencies {
          // gson-support( added since 1.2.0)
          compile 'com.heaven7.java.data.mediator.support.gson:data-mediator-support-gson:<see release>'

          compile 'com.heaven7.android.data.mediator:data-mediator-android:<see release>'
      
      }
    • if you use gradle version >=4.1. use 'annotationProcessor' directly.
     dependencies {
          // gson-support( added since 1.2.0)
          compile 'com.heaven7.java.data.mediator.support.gson:data-mediator-support-gson:<see release>'

          compile "com.google.code.gson:gson:2.8.2"
          // if you want to support data-bind of android
          compile 'com.heaven7.android.data.mediator:data-mediator-android:<see release>'
    
      }

Quick Start.

1,[Optional] global configuration.

@GlobalConfig(
        gsonConfig = @GsonConfig(
                version = 2.0,
                forceDisable = false,
                generateJsonAdapter = true
        )
)

2, define your data module。eg: if i want to define a student module , and need impl Serializable, Parcelable. And if the student module has age, name, id property。 thus the simple data module can be define like :

@Fields({
        @Field(propName = "age" , type = int.class),
        @Field(propName = "name" , type = String.class),
        @Field(propName = "id" , type = long.class),
})
public interface Student extends Serializable, Parcelable{
}

3, use 'data-mediator-intellij-plugin' generate code, hot key like alt + insert. (you should instanll the plugin , see release).

4, call sample (from project(data-mediator-demo) TestPropertyChangeActivity

/**
 * listen property change demo
 * Created by heaven7 on 2017/9/18 0018.
 */
public class TestPropertyChangeActivity extends BaseActivity {

    @BindView(R.id.tv_desc)
    TextView mTv_desc;

    @BindView(R.id.bt_set_text_on_TextView)
    Button mBt_changeProperty;
    @BindView(R.id.bt_set_text_on_mediator)
    Button mBt_temp;

    DataMediator<Student> mMediator;


    @Override
    protected int getLayoutId() {
        return R.layout.ac_test_double_bind;
    }

    @Override
    protected void onInit(Context context, Bundle savedInstanceState) {
        mBt_changeProperty.setText("click this to change property");
        mBt_temp.setVisibility(View.GONE);

        //create data mediator from data module
        mMediator = DataMediatorFactory.createDataMediator(Student.class);
        //add callback
        mMediator.addDataMediatorCallback(new DataMediatorCallback<Student>() {
            @Override
            public void onPropertyValueChanged(Student data, Property prop, Object oldValue, Object newValue) {
                Logger.w("TestPropertyChangeActivity","onPropertyValueChanged","prop = "
                        + prop.getName() + " ,oldValue = " + oldValue + " ,newValue = " + newValue);
                mTv_desc.setText(String.valueOf(newValue));
            }
        });
        mMediator.getDataProxy().setName("heaven7");
    }

    @OnClick(R.id.bt_set_text_on_TextView)
    public void onClickSetTextOnTextView(View v){
        mMediator.getDataProxy().setName("time: " + System.currentTimeMillis());
    }
}

Proguard

-dontwarn com.heaven7.adapter.**
-keepclasseswithmembers public class * implements com.heaven7.java.data.mediator.DataPools$Poolable{
   *;
