2020/11/04 - [안드로이드] - [안드로이드]빗썸 api를 사용해서 현재 매도/매수 정보 가져오기
이번시간에는 해당 코인 체결내역을 가져오는걸 만들겠습니다. 아래는 빗썸 거래소에서 보여주는 체결내역입니다.
1. 환경설정app -> AndroidManifest.xml
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.kwon.coin">
<uses-permission android:name="android.permission.INTERNET" />
<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"
android:usesCleartextTraffic="true"
>
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<uses-library
android:name="org.apache.http.legacy"
android:required="false" />
</application>
</manifest>
2. 라이브러리 추가
Gradle Scripts -> build.gradle(Module:app)
implementation 'com.android.volley:dc-volley:1.1.0'
implementation 'com.google.code.gson:gson:2.8.6'
implementation 'androidx.cardview:cardview:1.0.0'
implementation 'androidx.recyclerview:recyclerview:1.1.0'
3. 클래스 추가(Java -> 마우스 오른쪽 -> New -> Java Class)

7. 구동화면
코인명을 입력하고 조회버튼을 누르면 해당코인 현재 체결내역을 가져옵니다.
매도는 파란색, 매수는 빨간색으로 표시했습니다.
