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
<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.example.ly.scanrfid"> <uses-permission android:name="android.permission.CAMERA"/> <uses-permission android:name="android.permission.VIBRATE"/> <uses-permission android:name="android.permission.INTERNET"/> <application android:allowBackup="true" android:icon="@mipmap/ic_launcher" android:label="@string/app_name" android:supportsRtl="true" android:theme="@style/AppTheme"> <activity android:name=".MainActivity"> <intent-filter> <action android:name="android.intent.action.MAIN"/> <category android:name="android.intent.category.LAUNCHER"/> </intent-filter> </activity> </application> </manifest>
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(); } } }
