在開發過程中有很多重復的代碼沒有必要每次詳細的編寫，下面以一鍵生成MVP相關代碼以及對應的Fragment或者Activity
首先去intellij idea官網下在開發環境，可以免費使用三十天；
1、創建插件項目，File->New ->Project 打開窗口后選擇Intellij Platform Plugin，選擇對應的Project SDK版本，點擊Next選擇位置，示意圖如下:

2、在src中創建Action幫助，New->Plugin Devkit -> Action,輸入相關的信息，選擇Action的分組、位置以及快捷鍵等想信息，選擇group分組最好根據你具體的插件的功能決定，比如生成代碼的功能可以在CodeMenu中也可以在NewGroup更方便,創建完成后可以在resources->plugin.xml中看到注冊的Action信息，可以修改發布插件的其他相關信息；

  <idea-version since-build="145.0"/>

  -->

  <extensions defaultExtensionNs="com.intellij">
    <!-- Add your extensions here -->
  </extensions>

  <actions>
    <!-- Add your actions here -->
    <action id="Android.Activity.MvpHelpers" class="com.MvpGeneratorAction" text="ActivityMvp"
            description="generate mvp relatived code files:Activity ,Fragment,Contract,Model,Presenter">
      <add-to-group group-id="NewGroup" anchor="first"/>
      <keyboard-shortcut keymap="$default" first-keystroke="shift ctrl alt G"/>
    </action>

    <action id="Android.Fragment.MvpHelpers" class="com.MvpGeneratorAction" text="FragmentMvp"
            description="generate mvp relatived code files:Activity ,Fragment,Contract,Model,Presenter">
      <add-to-group group-id="NewGroup" anchor="before" relative-to-action="Android.Activity.MvpHelpers"/>
    </action>
  </actions>
</idea-plugin>

3、在創建的Action類中，覆蓋actionPerformed方法，加入相關的業務邏輯代碼，舉例：

@Override
    public void actionPerformed(AnActionEvent e) {
        // TODO: insert action logic here｀｀｀
        mProject = e.getData(PlatformDataKeys.PROJECT);
        mPackageName = getPackageName();

        DataContext dataContext = e.getDataContext();
        VirtualFile file = DataKeys.VIRTUAL_FILE.getData(dataContext);
        if (file != null && file.exists()){
            mMenuRelativePath = file.getPath();
            handleMenuPackagePath();
        }else{
            throw new RuntimeException("未獲取到文件夾路徑！");
        }
}

4、創建生成代碼的模板文件，我這里直接寫到txt文件中創建時直接替換掉相關的信息，比如創建Activity的模板文件的內容：

package $packagename.activity;

import android.os.Bundle;
import $basemvppackage.mvp.BaseActivity;
import $packagename.mvp.$nameContract;
import $packagename.mvp.$nameModel;
import $packagename.mvp.$namePresenter;
import $basepackagename.R;

/**
 * @author $author
 * @Package $packagename
 * @Description: $description
 * @date $date
 **/
public class $nameActivity extends BaseActivity<$namePresenter,$nameModel> implements $nameContract.View{


    @Override
     protected void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
     }

     @Override
     protected int getLayoutId() {
        return 0;
     }

     @Override
     protected void initPresenter() {
         mPresenter.setVM(this,mModel);
     }

     @Override
     protected void initView(){

     }

     @Override
     public void showLoading(String content) {
     }

     @Override
     public void stopLoading() {
     }

     @Override
     public void showErrorTip(String msg) {
     }

     @Override
     protected void onDestroy() {
         super.onDestroy();
     }

}

5、創建Dialog輸入相關的信息，替換模板中的相關字段，比如authorName和ModuleName，運行效果如下,項目地址
