1、lambda 缩写形式,studio 按键 alt+enter
2、studio 安装插件,gsonformat、butterknife插件,
提交代码使用svn插件管理。
设置studio中插件svn
本地文件过滤:
3、MVP的使用
一个模块对应一个 package包
主页home activity adapter domain 业务处理 usecase fragment 这个如果activity支持刷新,添加一个BaseListFragment presenter view widget 自定义的view
mvp使用列子:
详情界面
1. 定义一个view 接口
public interface PeriodInvestProdDetailView extends LoadDataView {
void onShowPeriodInvestProdDetail(FixedPeriodInvestProdResp fixedPeriodInvestProdResp);//产品详情
}
2. usecase 做业务 处理,一般耗时操作
package com.lcwr.android.modules.investment.domain;
import com.lcwr.android.data.entities.response.FixedPeriodInvestProdResp;
import com.lcwr.android.data.repository.Repository;
import com.lcwr.android.mvp.domain.UseCase;
import javax.inject.Inject;
import rx.Observable;
/** * author lihui * version 1.0 * date: on 2017/7/13 */
public class PeriodInvestProdDetailUseCase extends UseCase<FixedPeriodInvestProdResp> {
private Repository mRepository;
private String prdId;
public void setPrdId(String prdId) {
this.prdId = prdId;
}
@Inject
public PeriodInvestProdDetailUseCase(Repository repository) {
this.mRepository = repository;
}
@Override
protected Observable<FixedPeriodInvestProdResp> buildObservable() {
return mRepository.getFixedPeriodInvestProdDetail(prdId);
}
}
注:
mRepository.getFixedPeriodInvestProdDetail(prdId);这个里面处理耗时操作的,如请求服务器。
Observable使用了rxjava+rxandroid请求。
3. 对应presenter,管理view 和 usecase交互。
package com.lcwr.android.modules.investment.presenter;
import com.fernandocejas.frodo.annotation.RxLogSubscriber;
import com.lcwr.android.data.entities.response.FixedPeriodInvestProdResp;
import com.lcwr.android.modules.investment.domain.ElcAccountUseCase;
import com.lcwr.android.modules.investment.domain.PeriodInvestProdDetailUseCase;
import com.lcwr.android.modules.investment.view.PeriodInvestProdDetailView;
import com.lcwr.android.mvp.presenters.Presenter;
import com.lcwr.android.mvp.subscribers.LoadDataSubscriber;
import com.lcwr.android.mvp.views.InterfaceView;
import com.lcwr.android.mvp.views.LoadDataView;
import com.xitaiinfo.library.compat.errorview.ErrorView;
import com.xitaiinfo.library.injections.ActivityScope;
import javax.inject.Inject;
/** 1. author qibo 2. version 1.0 3. Create by 2017/7/20 上午11:58 4. 描述:理财详情 */
@ActivityScope
public class PeriodInvestProdDetailPresenter implements Presenter {
private PeriodInvestProdDetailView view;
private PeriodInvestProdDetailUseCase periodInvestProdDetailUseCase;
private String mPrdId;
@Inject
public PeriodInvestProdDetailPresenter(PeriodInvestProdDetailUseCase periodInvestProdDetailUseCase,ElcAccountUseCase elcAccountUseCase) {
this.periodInvestProdDetailUseCase = periodInvestProdDetailUseCase;
}
@Override
public void onResume() {
}
@Override
public void onPause() {
}
@Override
public void onDestroy() {
periodInvestProdDetailUseCase.unSubscribe();
}
@Override
public void attachView(InterfaceView v) {
this.view = (PeriodInvestProdDetailView) v;
}
/** * 产品具体详情 */
public void getPeriodInvestProductDetail(String prdId) {
this.mPrdId = prdId;
periodInvestProdDetailUseCase.setPrdId(prdId);
periodInvestProdDetailUseCase.execute(new PeriodInvestProductDetailSubscriber(view,() -> {
getPeriodInvestProductDetail(mPrdId);
},null));
}
@RxLogSubscriber
private class PeriodInvestProductDetailSubscriber extends LoadDataSubscriber<FixedPeriodInvestProdResp> {
public PeriodInvestProductDetailSubscriber(LoadDataView view,ErrorView.OnRetryListener onRetryListener,ErrorView.Config config) {
super(view,onRetryListener,config);
}
@Override
public void onNext(FixedPeriodInvestProdResp fixedPeriodInvestProdResp) {
super.onNext(fixedPeriodInvestProdResp);
view.onShowPeriodInvestProdDetail(fixedPeriodInvestProdResp);
}
}
}
注:
PeriodInvestProductDetailSubscriber 这个是rxjava中的订阅者,内部方法被回调。
4. 实现接口
接口都是需要被实现的(PeriodInvestProdDetailView ),
可以由Activity或者fragment实现,由于这里Activity实现接口。
public class PeriodInvestProdDetailActivity extends ToolBarActivity implements PeriodInvestProdDetailView,View.OnClickListener {
。。。
@Override
public void onShowPeriodInvestProdDetail(FixedPeriodInvestProdResp fixedPeriodInvestProdResp) {
mPrdName.setText(fixedPeriodInvestProdResp.getPrdName());
//限新手标
if (!TextUtils.isEmpty(fixedPeriodInvestProdResp.getPrdRecommend())) {
mPrdType.setText(fixedPeriodInvestProdResp.getPrdRecommend());
}
String rate = "0.0%";
if (TextUtils.isEmpty(fixedPeriodInvestProdResp.getRate())) {
rate = getString(R.string.home_hot_product_rate,fixedPeriodInvestProdResp.getPrdRate());
} else {
//4.5+1.5%
rate = getString(R.string.product1_rate,fixedPeriodInvestProdResp.getPrdRate(),fixedPeriodInvestProdResp.getRate());
}
mPrdrate.setText(rate);//6.2+7%
mPrdTerm.setText(fixedPeriodInvestProdResp.getPrdTerm() + "天");
//5种类型
mAvilAmount.setText(StringUtils.format(fixedPeriodInvestProdResp.getAvilAmount()) + "元");
mChargeAmount.setText(StringUtils.format(fixedPeriodInvestProdResp.getChargeAmount()) + "元");
mStartAmount.setText(StringUtils.format(fixedPeriodInvestProdResp.getStartAmount()) + "元");
String incomeMode = fixedPeriodInvestProdResp.getIncomeMode();
if (!TextUtils.isEmpty(incomeMode)) {
mIncomeMode.setText(incomeMode);
}
String convFalg = fixedPeriodInvestProdResp.getConvFalg();
if (!TextUtils.isEmpty(convFalg)) {
mConvFlag.setText(convFalg);
}
}
。。。
}
Model:usercase
presenter:管理者
view:数据返回接口,Activity/fragment实现该接口
4、框架
注解框架
//ButterKnife
compile "com.jakewharton:butterknife:${libs.butterknife}"
annotationProcessor "com.jakewharton:butterknife-compiler:${libs.butterknife}"
RxBinding 是 Jake Wharton 的一个开源库,它提供了一套在 Android 平台上的基于 RxJava的 Binding API。所谓 Binding,就是类似设置 OnClickListener 、设置 TextWatcher 这样的注册绑定对象的API,对普通的控件,V4,V7等等做了相应的支持。
在Rxbinding的基础上可以很方便的实现很多功能,例如:快点点击两次只取一次、长按事件监听、编辑框快速输入时候不搜索等等功能。

etProjectedEarnings.setText("0.00");
