使用Android Studio

一、在build.gradle(Module:app)添加代码  下载，调用插件

apply plugin: 'com.android.application'

android {

compileSdkVersion 24

buildToolsVersion "24.0.1"

defaultConfig {

applicationId "com.example.ly.scanrfid"

minSdkVersion 19

targetSdkVersion 24

versionCode 1

versionName "1.0"

}

buildTypes {

release {

minifyEnabled false

proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

}

}

repositories {

mavenCentral()

maven {

url "http://dl.bintray.com/journeyapps/maven"

}

}

}

dependencies {

compile fileTree(dir: 'libs', include: ['*.jar'])

testCompile 'junit:junit:4.12'

compile 'com.android.support:appcompat-v7:24.2.1'

// Supports Android 4.0.3 and later (API level 15)

compile 'com.journeyapps:zxing-android-embedded:2.0.1@aar'

// Supports Android 2.1 and later (API level 7), but not optimal for later Android versions.

// If you only plan on supporting Android 4.0.3 and up, you don't need to include this.

compile 'com.journeyapps:zxing-android-legacy:2.0.1@aar'

// Convenience library to launch the scanning and encoding Activities.

// It automatically picks the best scanning library from the above two, depending on the

// Android version and what is available.

compile 'com.journeyapps:zxing-android-integration:2.0.1@aar'

// Version 3.0.x of zxing core contains some code that is not compatible on Android 2.2 and earlier.

// This mostly affects encoding, but you should test if you plan to support these versions.

// Older versions e.g. 2.2 may also work if you need support for older Android versions.

compile 'com.google.zxing:core:3.0.1'

}

二、添加权限

package="com.example.ly.scanrfid">

android:allowBackup="true"

android:icon="@mipmap/ic_launcher"

android:label="@string/app_name"

android:supportsRtl="true"

android:theme="@style/AppTheme">

三、Activity代码

package com.example.ly.scanrfid;

import android.content.Intent;

import android.support.v7.app.AppCompatActivity;

import android.os.Bundle;

import android.util.Log;

import android.view.View;

import android.widget.Toast;

import com.google.zxing.integration.android.IntentIntegrator;

import com.google.zxing.integration.android.IntentResult;

public class MainActivity extends AppCompatActivity {

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

}

// 扫描按钮点击监听事件

public void clickScan(View view) {

//扫描操作

IntentIntegrator integrator = new IntentIntegrator(MainActivity.this);

integrator.initiateScan();

}

@Override

protected void onActivityResult(int requestCode, int resultCode, Intent data) {

// 跳转扫描页面返回扫描数据

IntentResult scanResult = IntentIntegrator.parseActivityResult(requestCode, resultCode, data);

// 判断返回值是否为空

if (scanResult != null) {

//返回条形码数据

String result = scanResult.getContents();

Log.d("code", result);

Toast.makeText(this, result, Toast.LENGTH_LONG).show();

}

}

}
