先在 build.gradle(Project:XXXX) 的 repositories 添加 maven { url 'https://jitpack.io' }
一定要加上这个，否则会提示依赖失败
allprojects {
repositories {
google()
jcenter()
maven { url 'https://jitpack.io' }
}
}
然后在 build.gradle(Module:app) 的 dependencies 添加:
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
implementation 'androidx.appcompat:appcompat:1.0.0'
/*添加依赖*/
implementation 'com.github.353717203:zxing-master:3.0.0'
}
需要申请的权限有：
Manifest.permission.CAMERA
Manifest.permission.READ_EXTERNAL_STORAGE
项目中用到的所有权限
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.FLASHLIGHT" />
<uses-feature android:name="android.hardware.camera" />
<uses-feature android:name="android.hardware.camera.autofocus" />
<uses-permission android:name="android.permission.VIBRATE" />
<uses-permission android:name="android.permission.WAKE_LOCK" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
1.使用默认配置项
Intent intent = new Intent(MainActivity.this, CaptureActivity.class);
startActivityForResult(intent, REQUEST_CODE_SCAN);
2.自定义配置项
Intent intent = new Intent(MainActivity.this, CaptureActivity.class);
/*ZxingConfig是配置类
ZxingConfig config = new ZxingConfig();
config.setPlayBeep(true);//是否播放扫描声音 默认为true
config.setShake(true);//是否震动 默认为true
config.setDecodeBarCode(true);//是否扫描条形码 默认为true
config.setReactColor(R.color.colorAccent);//设置扫描框四个角的颜色 默认为白色
config.setFrameLineColor(R.color.colorAccent);//设置扫描框边框颜色 默认无色
config.setScanLineColor(R.color.colorAccent);//设置扫描线的颜色 默认白色
config.setFullScreenScan(false);//是否全屏扫描 默认为true 设为false则只会在扫描框中扫描
intent.putExtra(Constant.INTENT_ZXING_CONFIG, config);
startActivityForResult(intent, REQUEST_CODE_SCAN);
4.接收扫描结果
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
// 扫描二维码/条码回传
if (requestCode == REQUEST_CODE_SCAN && resultCode == RESULT_OK) {
if (data != null) {
String content = data.getStringExtra(Constant.CODED_CONTENT);
result.setText("扫描结果为：" + content);
}
}
}
