简单的Android Studio 翻译插件
英语水平太差劲，这是个很无奈的事情，在android studio里面看源码，注释看不懂！怎么办呢，安装个插件吧！搜了一下，就搜到一个，还没写怎么用。自己写一个简单的吧。在网上找了一下教程，照葫芦画瓢，最后做出来了，记录一下吧。
一、先下一个IntelliJ IDEA，安装好
https://www.jetbrains.com/idea/download/
二、新建一个IntelliJ Platform Plugin 工程
ProjectSDK : 点击New，选择IntelliJ 的根目录就可以。
next ，起个名，finish。
三、新建一个Action
在src文件夹上右键->New->Action
Class Name : 生成的java文件名，Name : 在菜单中显示的名称，Groups:在那组菜单中显示，Keyboard Shortcuts :用于设置快捷键。点击OK会生成TranslationAction.java文件。
四、先显示一个MessageDialog吧
在TranslationAction.java里面添加代码：
@Override
public void actionPerformed(AnActionEvent e) {
// TODO: insert action logic here
Messages.showMessageDialog(
"试一试看看效果",
"这是标题",
Messages.getInformationIcon());
}点击Run，会打开一个IntelliJ 窗口，刚才action选择了EditMenu，在Edit下可以发现一个名为translate的选项，快捷键是ALT+A。
点击一下：
六、接下来就是实现翻译功能啦
用有道API实现吧。地址：http://fanyi.youdao.com/openapi?path=data-mode
申请一个，网站名称，网站地址随便写，无所谓的东西。申请成功，会有一个 keyfrom 和 key。
七、封装数据
下面是我封装的数据格式。
package com.lcy.plugin;
import java.util.List;
import java.util.Map;

public class Translation {
public final static String US_PHONETIC = "us-phonetic";
public final static String UK_PHONETIC = "uk-phonetic";
public final static String PHONETIC = "phonetic";
public final static String EXPLAINS = "explains";
private final static int SUCCESS = 0;
private final static int QUERY_STRING_TOO_LONG = 20;
private final static int CAN_NOT_TRANSLATE = 30;
private final static int INVALID_LANGUAGE = 40;
private final static int INVALID_KEY = 50;
private final static int NO_RESULT = 60;
private String[] translation;
private String query;
private int errorCode;
private Map basic;
private List> web;
public String[] getTranslation() {
return translation;
}
public void setTranslation(String[] translation) {
this.translation = translation;
}
public String getQuery() {
return query;
}
public void setQuery(String query) {
this.query = query;
}
public int getErrorCode() {
return errorCode;
}
public void setErrorCode(int errorCode) {
this.errorCode = errorCode;
}
public Map getBasic() {
return basic;
}
public void setBasic(Map basic) {
this.basic = basic;
}
public List> getWeb() {
return web;
}
public void setWeb(List> web) {
this.web = web;
}
public String getErrorMessage() {
switch (errorCode) {
case SUCCESS:
return "成功";
case QUERY_STRING_TOO_LONG:
return "要翻译的文本过长";
case CAN_NOT_TRANSLATE:
return "无法进行有效的翻译";
case INVALID_LANGUAGE:
return "不支持的语言类型";
case INVALID_KEY:
return "无效的key";
case NO_RESULT:
return "无词典结果";
}
return "这是什么鬼";
}
public String getPhonetic() {
if (basic == null) {
return null;
}
String phonetic = null;
String us_phonetic = (String) basic.get(US_PHONETIC);
String uk_phonetic = (String) basic.get(UK_PHONETIC);
if (us_phonetic == null && uk_phonetic == null) {
phonetic = "拼音：[" + (String) basic.get(PHONETIC) + "];";
} else {
if (us_phonetic != null) {
phonetic = "美式：[" + us_phonetic + "];";
}
if (uk_phonetic != null) {
if(phonetic == null)
{
phonetic = "";
}
phonetic = phonetic + "英式：[" + uk_phonetic + "];";
}
}
return phonetic;
}
public String getExplains() {
if (basic == null) {
return null;
}
String result = null;
List explains = (List) basic.get(EXPLAINS);
if (explains.size() > 0) {
result = "";
}
for (String explain : explains) {
result += explain + "\n";
}
return result;
}
public String getTranslationResult() {
if (translation == null) {
return null;
}
String result = null;
if(translation.length>0) {
result = "";
}
for (String r : translation) {
result += (r + ";");
}
return result;
}
public String getWebResult() {
if (web == null) {
return null;
}
String result = null;
if (web.size() > 0) {
result = "";
}
for (Map map : web) {
String key = (String) map.get("key");
result += (key + " : ");
List value = (List) map.get("value");
for (String str : value) {
result += (str + ",");
}
result += "\n";
}
return result;
}
@Override
public String toString() {
String string = null;
if (errorCode != SUCCESS) {
string = "错误代码：" + errorCode + "\n" + getErrorMessage();
} else {
String translation = getTranslationResult();
if (translation != null) {
translation = translation.substring(0, translation.length() - 1);
if(!translation.equals(query)) {
string = (query + ":" + getTranslationResult() + "\n");
}
}
if (getPhonetic() != null) {
if (string == null) {
string = "";
}
string += (getPhonetic() + "\n");
}
if (getExplains() != null) {
if (string == null) {
string = "";
}
string += (getExplains());
}
if (getWebResult() != null) {
if (string == null) {
string = "";
}
string+="网络释义：\n";
string += (getWebResult());
}
}
if(string == null)
{
string = "你选的内容："+query+"\n这是个毛线！！！\n翻译不了！";
}
return string;
}
}
八、获取选中的文字
发挥自己想象力的时候到了，根据IntelliJ 的代码提示功能，试了几次竟然成功了。
@Override
public void actionPerformed(AnActionEvent e) {
//获取编辑器
Editor editor = e.getData(PlatformDataKeys.EDITOR);
if (editor != null) {
SelectionModel model = editor.getSelectionModel();
//获取选中的文本
String selectedText = model.getSelectedText();
if (selectedText != null) {
//翻译并显示
getTranslation(selectedText);
}
}
}我是用httpclient4.5实现的，下载地址：http://hc.apache.org/downloads.cgi
private void getTranslation(String query) {
try {
//获取URI
URI uri = createTranslationURI(query);
System.out.println(uri.toString());
//配置GET请求
RequestConfig requestConfig = RequestConfig.custom().setSocketTimeout(5000).setConnectTimeout(5000)
.setConnectionRequestTimeout(5000).build();
HttpGet httpGet = new HttpGet(uri);
httpGet.setConfig(requestConfig);
HttpClient client = HttpClients.createDefault();
//请求网络
HttpResponse response = client.execute(httpGet);
int status = response.getStatusLine().getStatusCode();
if (status >= 200 && status < 300) {
//获取响应数据
HttpEntity resEntity = response.getEntity();
String json = EntityUtils.toString(resEntity, "UTF-8");
//转化为Translation对象
Gson gson = new Gson();
Translation translation = gson.fromJson(json, Translation.class);
//显示结果
Messages.showMessageDialog(
translation.toString(),
"翻译结果",
Messages.getInformationIcon()
);
} else {
//显示错误代码和错误信息
Messages.showMessageDialog(
response.getStatusLine().getReasonPhrase(),
"错误代码：" + status,
Messages.getInformationIcon()
);
}
} catch (IOException e) {
//显示异常信息
Messages.showMessageDialog(
e.getMessage(),
"啊欧，崩溃了",
Messages.getInformationIcon()
);
} catch (URISyntaxException e) {
e.printStackTrace();
}
}
/**
* 生成URI
*
* @param query 查询内容
* @return URI
* @throws URISyntaxException
*/
private URI createTranslationURI(String query) throws URISyntaxException {
URIBuilder builder = new URIBuilder();
builder.setScheme("http")
.setHost(HOST)
.setPath(PATH)
.addParameter(PARAM_KEY_FROM, KEY_FROM)
.addParameter(PARAM_KEY, KEY)
.addParameter(PARAM_TYPE, TYPE)
.addParameter(PARAM_VERSION, VERSION)
.addParameter(PARAM_DOC_TYPE, DOC_TYPE)
.addParameter(PARAM_CALL_BACK, CALL_BACK)
.addParameter(PARAM_QUERY, query)
;
return builder.build();
}Builde->Prepare Plgin Module ‘MyTranslation’For Deployment，就会在工程目录下生成MyTranslation.zip文件。然后，settings->Plugins->Install Plugin from Disk，找到刚才生成的文件安装即可，安装完重启，看看效果。
效果图 ：
界面比较挫，音标还出现乱码，还好能用。
