Android(Java)解析有道翻译API-Json数据

由于百度翻译、有道翻译等翻译服务都开放了自己的API,开发者可以使用它们提供的API很简单就能开发出自己的翻译软件。自己开发的软件可能在功能上不及它们强大,但是翻译的结果是一样的,同时不会内置其它偷跑流量的进程,同时界面也相对简洁,随心所欲地进行修改。 API 首先在有道API进行申请API ID和KEY后,将下列程序中clientID和clientSecret替换为ID和KEY,通过GET请求获得字符串进行解析。下面是我使用java解析JSON数据的代码:

private String clientID=”你在有道API申请的ID”;
private String clientSecret=”你在有道API申请的密钥”;
Handler errHander = new Handler() {
@Override
public void handleMessage(Message msg) {
String notice = “”;
switch (msg.what) {
case 20:
notice = “要翻译的文本过长”;
break;
case 30:
notice = “无法进行有效的翻译”;
break;
case 40:
notice = “不支持的语言类型”;
break;
case 50:
notice = “无效的key”;
break;
case 60:
notice = “无词典结果”;
break;
}
Toast.makeText(MainActivity.this, notice, Toast.LENGTH_SHORT);
}
};
Handler hander = new Handler() {
@Override
public void handleMessage(Message msg) {

        if (msg.what == 0x123) {
            toString.setText(reply);
        } else if (msg.what == 0x124) {
            Toast.makeText(MainActivity.this, "查询失败,请检查联网", Toast.LENGTH_SHORT).show();
        }
