Idea/AndroidStudio插件学习记录

说明

只为学习使用,环境配置请百度 资料太少了

1 常用API

//获取正在编辑的文件
PsiJavaFile javaFile = (PsiJavaFile) e.getData(CommonDataKeys.PSI_FILE);

javaFile.getPackageName()//包名

javaFile.getName()//文件名 qqq.java

//获取编辑的文件,可以拿到绝对路径和名称
VirtualFile currentFile = DataKeys.VIRTUAL_FILE.getData(AnActionEvent.getDataContext());

//获取编辑对象
 _editor = e.getData(PlatformDataKeys.EDITOR);
 //获取正在编辑的文本内容
 _content = _editor.getDocument().getText();

//根据情况选择是否显示 菜单 (不会用,暂时没有使用)
 public static String getFileExtension(DataContext dataContext) {
        VirtualFile file = DataKeys.VIRTUAL_FILE.getData(dataContext);
        return file == null ? null : file.getExtension();
    }
    
  @Override
    public void update(AnActionEvent event) {
        //在Action显示之前,根据选中文件扩展名判定是否显示此Action
        String extension = getFileExtension(event.getDataContext());
        this.getTemplatePresentation().setEnabled(extension != null && "jar".equals(extension));
    }

//修改完目录结构后,刷新目录结构
  // 第一个参数:是否异步
  //第二个参数:是否递归
  //第三个参数:完成后的回调
  //不建议获取项目的baseDir.使用的时候可以获取生成的当前目录,类型为 VirtualFile
  getEventProject(e).getBaseDir().refresh(true, true, new Runnable() {
                @Override
                public void run() {
                    MessagesCenter.showMessage("目录刷新成功", "创建成功");
                }
            });

//悬浮框的展示
 JBPopupFactory factory = JBPopupFactory.getInstance();
                factory.createHtmlTextBalloonBuilder(result, null, 
                new JBColor(new Color(186, 238, 186),
                 new Color(73, 117, 73)), null)
                        .setFadeoutTime(5000)
                        .createBalloon()
                        .show(factory.guessBestPopupLocation(editor), Balloon.Position.below);

//替换内容
private void changeSelectText(String text) {
    Project  mProject = e.getData(PlatformDataKeys.PROJECT);
    Document document = mEditor.getDocument();
    SelectionModel selectionModel = mEditor.getSelectionModel();

    final int start = selectionModel.getSelectionStart();
    final int end = selectionModel.getSelectionEnd();
    Runnable runnable = new Runnable() {
        @Override
        public void run() {
            document.replaceString(start, end, text);
        }
    };
    WriteCommandAction.runWriteCommandAction(mProject, runnable);
    selectionModel.removeSelection();
}

关于Dialog的操作和java swing类似,可以搜索java swing的资料

        //设置大小
        setMinimumSize(new Dimension(800,800));
        //居中
        Toolkit kit = Toolkit.getDefaultToolkit(); // 定义工具包
        Dimension screenSize = kit.getScreenSize(); // 获取屏幕的尺寸
        int screenWidth = screenSize.width / 2; // 获取屏幕的宽
        int screenHeight = screenSize.height / 2; // 获取屏幕的高
        int height = this.getHeight();
        int width = this.getWidth();
        setLocation(screenWidth - width / 2, screenHeight - height / 2);
        //使用
         TestDialog testDialog = new TestDialog();
         testDialog.setVisible(true);

关于设置信息的保存,直接引用了别人写好的一个类,很简单

import com.intellij.ide.util.PropertiesComponent;

/**
 * Created by Roy on 2016/7/8.
 */
public class PropertiesUtil {

    private static final String PROPERYIES_NAME_LIST = "varnamesettings_list";
    private static final String PROPERYIES_NAME_CHECKBOX = "varnamesettings_check";

    /**
     * 获取设置参数列表
     *
     * @return
     */
    public static String[] getProperties() {
        if (PropertiesComponent.getInstance().isValueSet(PROPERYIES_NAME_LIST)) {
            return PropertiesComponent.getInstance().getValues(PROPERYIES_NAME_LIST);
        } 
    }

    /**
     * 保存参数列表
     *
     * @param array
     */
    public static void saveProperties(String[] array) {
        PropertiesComponent.getInstance().setValues(PROPERYIES_NAME_LIST, array);
    }

    /**
     * 保存复选框状态
     *
     * @param selected
     */
    public static void saveCheckBoxSelectState(boolean selected) {
        PropertiesComponent.getInstance().setValue(PROPERYIES_NAME_CHECKBOX, selected);
    }

}

2 action groups

• GenerateGroup

• EditorMenu

其他: 具体的每个group-id的含义可参看： http://keithlea.com/idea-actions/
