Android use Youdao translation API real line translation function

In Android app, add the function of online translator, here is the Youdao translation API.

Use Youdao translation API. First of all to apply for a key, the application address is: Youdao translation API application address.

After applying, you will get a Keyfrom and a key.

The data interface for obtaining the translation results is:http://fanyi.youdao.com/openapi.do?

keyfrom=<keyfrom>&key=<key>&type=data&doctype=<doctype >&version=1.1&q= the text to be translated. We just need to stitch things up like this. The way to use get. will be able to get the result of the translation.

I translated the "program Ape", the data returned by the interface is:

{"    translation": [        "the programmer"    ],    "basic": {        "phonetic": "Chéng Xùyuán",        "explains": [            "Programmer"        ]    },    "Query": "Program Ape",    "ErrorCode": 0,    "web": [        {            "value": [                " Programmer ",                " coder ",                " SCJP "            ],            " key ":" Program Ape "        },        {            " value ": [                " Systems Programmer ",                " Java Card ",                " System Programmer "            ],            " key ":" Program Ape "        },        {            " value ": [                "Programmer",                "computer programmer",                "Job-interviewcomputer programmer"            ],            "key": "Computer program Ape"        }    ]}

We just need to parse out what we need.

Detailed implementations such as the following:

Look at the effect:

Supplement: The translated text should be coded to be competent enough to prevent special characters.

Urlencoder.encode (content);
