如何在Android Studio中使用Google Cloud Translation API? [英] How to use Google Cloud Translation API in Android Studio?
问题描述
我正在制作一个用于语言翻译的android应用程序,到目前为止,我已经使用了语音识别器来将语音输入转换为字符串.现在,我想将该字符串翻译成另一种语言,并使用TTS引擎说出翻译后的文本.
我创建了一个单独的translate_test
文件供测试使用.我一直在研究,并且知道Android Studio需要API密钥.因此,我创建了API密钥并启用了 Google Cloud Translation API .
现在,我尝试在MainActivity中导入com.google.cloud.translate.Translation
,但出现此错误:
I am making an android app for language translation and so far I have used voice recognizer intent to get the voice input into a string. Now I want to translate that string into another language and speak the translated text using the TTS Engine.
I have created a separate translate_test
file just for test use. I have been researching and know that API Key is required in Android Studio. So I have created the API Key and enabled the Google Cloud Translation API.
Now I'm trying to import com.google.cloud.translate.Translation
in my MainActivity but I'm getting this error:
我需要10个信誉点才能显示图像.所以我只能说导入的文件不存在.
I NEED 10 REPUTATION POINTS TO ALLOW THE IMAGE TO BE SHOWN.So all I can say is that the imported file does not exist.
我需要有关如何包括云文件的帮助.我一直在进行在线研究,但仍然找不到教程或有关如何在Android Studio中包含云文件的任何信息.我什至读过文档.我需要帮助,如果有人可以给我一些简单的步骤,我将很高兴.
I need help on how to include the cloud files. I have been researching online but still not able to find a tutorial or any information on how to include the cloud files in Android Studio. I have even read the docs. I need help and will be pleased if someone can give me some simple steps.
这是我的MainActivity.java文件:
This is my MainActivity.java file:
package com.example.aman.translate_test;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.widget.TextView;
import com.google.cloud.translate.Translation;
public class MainActivity extends AppCompatActivity
{
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
TextView tv = (TextView) findViewById(R.id.textView);
}
}
这是我的AndroidManifest.xml文件:
This is my AndroidManifest.xml file:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.aman.translate_test">
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:roundIcon="@mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<uses-permission android:name="android.permission.INTERNET"/>
<uses-library android:name="com.google.cloud.translate.Translate" />
<meta-data
android:name="com.google.android.geo.API_KEY"
android:value="@string/api_key"/>
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
推荐答案
I guess you followed the steps outlined here: Google Translate API Docs
但这不能像文档中提到的那样在Android上运行:
But this doesn't work on Android as its mentioned in the docs:
注意:Google Cloud Java客户端库当前不支持Android.
Note: Google Cloud Java client libraries do not currently support Android.
因此,要开始使用Android,必须使用HTTP请求进行REST API调用.
So in order to get in working on Android, you have to make a REST API call using an HTTP request.
请阅读以下内容以获取更多信息:对Cloud Translation API进行身份验证
Read this for more info: Authenticating to the Cloud Translation API
节选:
发出任何Translation API请求时,请将您的密钥作为密钥参数的值传递.例如:
When making any Translation API request, pass your key as the value of a key parameter. For example:
POST https://translation.googleapis.com/language/translate/v2?key=YOUR_API_KEY
为每个字符串使用单独的q参数.此示例HTTP POST请求发送两个字符串进行翻译:
Use a separate q parameter for each string. This example HTTP POST request sends two strings for translation:
POST https://translation.googleapis.com/language/translate/v2?key=YOUR_API_KEY
{
'q': 'Hello world',
'q': 'My name is Jeff',
'target': 'de'
}
{
'q': 'Hello world',
'q': 'My name is Jeff',
'target': 'de'
}
