如果觉得写mvp有点枯燥无味，我们可以做点 cool 的事情：做个 as 插件

help.png

todo-mvp: 基础的MVP架构。

todo-mvp-loaders:基于MVP架构的实现，在获取数据的部分采用了loaders架构。

todo-mvp-databinding: 基于MVP架构的实现，采用了数据绑定组件。

todo-mvp-clean: 基于MVP架构的clean架构的实现。

todo-mvp-dagger2: 基于MVP架构，采用了依赖注入dagger2。

dev-todo-mvp-contentproviders: 基于mvp-loaders架构，使用了ContenPproviders。

dev-todo-mvp-rxjava: 基于MVP架构，对于程序的并发处理和数据层(MVP中的Model)的抽象。

因为对mvp的理解不同，会有很多种方式表达架构，所以插件要极简易读，可扩展性强，所以可以选择：

/**

* 通过模板生成类

* @param var1 文件生成路径

* @param var2 文件名

* @param var3 模板名

* @param var4 是否生产类

* @param var5 模板参数

*/

public abstract PsiClass createClass(@NotNull PsiDirectory var1, @NotNull String var2, @NotNull String var3, boolean var4, @NotNull Map var5) throws IncorrectOperationException;

也就是只要定制不同的模板就可以实现扩展性

直接贴下步骤：

action:

public class MvpGenerator extends AnAction implements MvpHandler.OnGenerateListener {

private AnActionEvent actionEvent;

private MvpHandler mvpHandler;

private Map map = new HashMap<>();

@Override

public void actionPerformed(AnActionEvent anActionEvent) {

this.actionEvent = anActionEvent;

mvpHandler = new MvpHandler();

mvpHandler.setTitle("输入名称-生成MVP相关类");

mvpHandler.setOnGenerateListener(this);

mvpHandler.pack();

//设置对话框跟随当前windows窗口

mvpHandler.setLocationRelativeTo(WindowManager.getInstance().getFrame(anActionEvent.getProject()));

mvpHandler.setVisible(true);

}

@Override

public void onGenerate(String text) {

JavaDirectoryService directoryService = JavaDirectoryService.getInstance();

//当前工程

Project project = actionEvent.getProject();

map.put("NAME", text);

map.put("PACKAGE_NAME", Util.getPackageName(project));

//鼠标右键所选择的路径

IdeView ideView = actionEvent.getRequiredData(LangDataKeys.IDE_VIEW);

PsiDirectory directory = ideView.getOrChooseDirectory();

assert directory != null;

if (directory.getName().contains("contract") && directory.findFile(text + "Contract.java") == null) {

directoryService.createClass(directory, text + "Contract", "GenerateContractFile", true, map);

}

if (directory.getName().contains("model") && directory.findFile(text + "Model.java") == null) {

directoryService.createClass(directory, text + "Model", "GenerateModelFile", true, map);

}

if (directory.getName().contains("presenter") && directory.findFile(text + "Presenter.java") == null) {

directoryService.createClass(directory, text + "Presenter", "GeneratePresenterFile", true, map);

}

}

@Override

public void onCancel() {

mvpHandler.setVisible(false);

}

}

dialog: (action下，右键，new dialog)

public class MvpHandler extends JDialog {

private JPanel contentPane;

private JButton buttonOK;

private JButton buttonCancel;

private JTextArea textArea1;

private OnGenerateListener listener;

public void setOnGenerateListener(OnGenerateListener listener) {

this.listener = listener;

}

});

// call onCancel() on ESCAPE

}

public interface OnGenerateListener{

void onGenerate(String text);

void onCancel();

}

}

MvpHandler.form 拖动控件

dialog.PNG

Util：

public class Util {

/**

* AndroidManifest.xml 获取 app 包名

* @return

*/

public static String getPackageName(Project project) {

String package_name = "";

DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();

try {

DocumentBuilder db = dbf.newDocumentBuilder();

Document doc = db.parse(project.getBasePath() + "/app/src/main/AndroidManifest.xml");

NodeList nodeList = doc.getElementsByTagName("manifest");

for (int i = 0; i < nodeList.getLength(); i++) {

Node node = nodeList.item(i);

Element element = (Element) node;

package_name = element.getAttribute("package");

}

} catch (Exception e) {

e.printStackTrace();

}

return package_name;

}

}

2： 定制模板：按需求定制

new - file - xxx.java.ft

GenerateContractFile.java.ft

#if (${PACKAGE_NAME} && ${PACKAGE_NAME} != "")

package ${PACKAGE_NAME};

#end

import base.IBaseModel;

import base.IBaseView;

import base.IPresenter;

public interface ${NAME}Contract{

interface I${NAME}View extends IBaseView{

}

interface I${NAME}Model extends IBaseModel{

}

interface I${NAME}Presenter extends IPresenter{

}

}

GenerateModelFile.java.ft

#if (${PACKAGE_NAME} && ${PACKAGE_NAME} != "")package ${PACKAGE_NAME};#end

import ${PACKAGE_NAME}.contract.${NAME}Contract;

import base.IBaseModel;

public class ${NAME}Model implements ${NAME}Contract.I${NAME}Model{

public static IBaseModel newInstance(){

return new ${NAME}Model();

}

}

GeneratePresenterFile.java.ft

#if (${PACKAGE_NAME} && ${PACKAGE_NAME} != "")

package ${PACKAGE_NAME}

;#end

import ${PACKAGE_NAME}.contract.${NAME}Contract;

import ${PACKAGE_NAME}.model.${NAME}Model;

import base.BasePresenter;

public class ${NAME}Presenter extends BasePresenter implements ${NAME}Contract.I${NAME}Presenter{

@Override

public ${NAME}Contract.I${NAME}Model bindModel(){

return (${NAME}Contract.I${NAME}Model)${NAME}Model.newInstance();

}

}

MVP:

BasePresenter:

public abstract class BasePresenter implements IPresenter {

protected T mView;

protected M mModel;

protected CompositeDisposable mDisposable;

public BasePresenter() {

this.mModel = bindModel();

mDisposable = new CompositeDisposable();

}

public boolean isViewAttached() {

return mView != null;

}

public void checkViewAttached() {

if (!isViewAttached()) throw new RuntimeException("未注册View");

}

@Override

public void onAttach(T t) {

mView = t;

if (mModel == null) {

throw new NullPointerException("model没有绑定 不能使用");

}

}

/**

* return Model

*/

public abstract M bindModel();

@Override

public void onDetach() {

if (!mDisposable.isDisposed())

mDisposable.dispose();

mView = null;

}

}

IBaseModel：

package base;

/**

* Created by haoran on 2018/4/4.

*/

public interface IBaseModel {

}

IBaseView ：

package base;

/**

* Created by haoran on 2017/10/30.

*/

public interface IBaseView {

void showLoading();

void hideLoading();

void onError(String message);

}

IPresenter：

package base;

/**

* Created by haoran on 2017/10/30.

*/

public interface IPresenter {

void onAttach(T t);

void onDetach();

}

实现类：(引导页为例)... import 忽略

GuideContract：

public interface GuideContract {

interface IGuideView extends IBaseView{

void showGuideImages(List pictureListBeans);

void showGuideDefaultImage();

}

interface IGuideModel extends IBaseModel {

Observable> getGuideImages();

}

interface IGuidePresenter extends IPresenter {

void getGuideImages();

}

}

GuideModel：

public class GuideModel implements GuideContract.IGuideModel {

public static IBaseModel newInstance() {

return new GuideModel();

}

public Observable> getGuideImages() {

return ApiHelper.get().getGuideImages(new JSONObject());

}

}

GuidePresenter：

public class GuidePresenter extends BasePresenter implements GuideContract.IGuidePresenter {

@Override

public void getGuideImages() {

checkViewAttached();

mDisposable.add(mModel.getGuideImages().subscribe(pictureList -> {

if (pictureList == null || pictureList.size() == 0) {

mView.showGuideDefaultImage();

} else {

mView.showGuideImages(pictureList);

}

}, throwable -> mView.showGuideDefaultImage()));

}

@Override

public GuideContract.IGuideModel bindModel() {

return (GuideContract.IGuideModel) GuideModel.newInstance();

}

}

根据自己实际的mvp实现类定制模板

3： 打包插件，as引入插件，使用插件(插件开发调试忽略)

打包：idea里 build - Prapare Pulgine Module 'xxx' for Developer

项目目录下的jar包

打开as -- setting pulgine import from disk : jar 包目录

重启as

选中目录(含contract ， model ，presenter) alt + i(快捷键可在plugine.xml配置)

或 右键 - new - 点击插件图标

输入 名称(XXX)--- 生成 java 类

generate1.PNG

点击ok
