本文主要是介绍Android IDE Plugin ViewInject,希望对大家解决编程问题提供一定的参考价值,需要的开发者们随着小编来一起学习吧!
前言
目前为止,Android使用的插件的已经很多了,但是自己在这块确实空白的,之前写过了ViewInject博客了,在优化findViewById之后,考虑到不需要手写问题的情况下,采用插件辅助来开发,网上目前已经有了ButterKnife的辅助的插件,为自己开发ViewInject插件,个人建议不要光看我写的一部分我用到的方法,需要你自己看IDE Plugin API刚好这段时间有空闲时间。
使用
在使用本插件之前,请使用https://blog.csdn.net/u012127961/article/details/70195693

插件导入方法
技术
IDE Plugin API : http://www.jetbrains.org/intellij/sdk/docs/basics/getting_started/publishing_plugin.html
(1)创建插件项目(http://www.jetbrains.org/intellij/sdk/docs/basics/getting_started/creating_plugin_project.html)
(2)创建Action (http://www.jetbrains.org/intellij/sdk/docs/basics/getting_started/creating_an_action.html)
(3)获取当前项目、编辑器、文档对象
@Overridepublic void actionPerformed(AnActionEvent e) {Project project = e.getProject();Editor editor = e.getData(CommonDataKeys.EDITOR);Document document = editor.getDocument();}
(4)显示提示信息
Messages.showMessageDialog("信息内容", "提示", Messages.getInformationIcon());
(5)获取鼠标选中文字
SelectionModel selectionMode = editor.getSelectionModel();String selectText = selectionMode.getSelectedText();
(6)获取当前打开的文件
PsiFile psiFile = e.getData(LangDataKeys.PSI_FILE);//e--->AnActionEvent String content = psiFile.getViewProvider().getContents().toString();//文件内容
(7)文件写入信息
Document document = editor.getDocument();WriteCommandAction.runWriteCommandAction(project, new Runnable() {@Overridepublic void run() {document.insertString(xx, xxxxx);}});
(8)替换文字
Document document = editor.getDocument();SelectionModel selectionModel = editor.getSelectionModel();int start = selectionModel.getSelectionStart();int end = selectionModel.getSelectionEnd();WriteCommandAction.runWriteCommandAction(project, () ->document.replaceString(start, end, "Replacement"));selectionModel.removeSelection();
(9)获取当前类
protected PsiClass getTargetClass(Editor editor, PsiFile file) {int offset = editor.getCaretModel().getOffset();PsiElement element = file.findElementAt(offset);if (element == null) {return null;} else {PsiClass target = (PsiClass) PsiTreeUtil.getParentOfType(element, PsiClass.class);return target instanceof SyntheticElement ? null : target;}
}
(10)获取ElementFactory
ElementFactory ElementFactory = JavaPsiFacade.getElementFactory(project);
(11)类操作
PsiClass psiClass = getTargetClass(editor, psiFile);
//添加字段 --- [其他方式可以更改createFieldFromText这里,还可以对方法、包都可以操作]
psiClass.add(JavaPsiFacade.getElementFactory(project).createFieldFromText("private Editext etxtUser;", psiClass));
