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语音识别器意图将语音输入输入到字符串中.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，仅供测试使用.我一直在研究并知道 Android Studio 中需要 API Key.所以我创建了 API 密钥并启用了 Google Cloud Translation API.现在我试图在我的 MainActivity 中导入 com.google.cloud.translate.Translation 但我收到这个错误:
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.
我需要有关如何包含云文件的帮助.我一直在网上研究，但仍然无法找到有关如何在 Android Studio 中包含云文件的教程或任何信息.我什至阅读了文档.我需要帮助，如果有人能给我一些简单的步骤，我会很高兴.
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
我猜你遵循了这里列出的步骤:Google 翻译 API 文档
I guess you followed the steps outlined here: Google Translate API Docs
但是这在文档中提到的 Android 上不起作用:
But this doesn't work on Android as its mentioned in the docs:
注意:Google Cloud Java 客户端库目前不支持 Android.
Note: Google Cloud Java client libraries do not currently support Android.
因此，为了在 Android 上工作，您必须使用 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.
阅读本文了解更多信息:向 Cloud Translation API 进行身份验证
Read this for more info: Authenticating to the Cloud Translation API
摘录:
在发出任何 Translation API 请求时，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
<代码>{'q': '你好世界','q': '我叫杰夫','目标':'德'}
