第一步：添加
implementation 'com.journeyapps:zxing-android-embedded:3.5.0'
第二步：
new IntentIntegrator(AccountLoginActivity.this)
.setCaptureActivity(CaptureActivity.class)
.setDesiredBarcodeFormats(IntentIntegrator.QR_CODE_TYPES)// 掃碼的類型,可選：一維碼，二維碼，一/二維碼
.setCameraId(0)// 選擇攝像頭,可使用前置或者後置
.setPrompt("")
.initiateScan();// 初始
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
// Result returned from launching the Intent from GoogleSignInClient.getSignInIntent(...);
IntentResult result = IntentIntegrator.parseActivityResult(requestCode, resultCode, data);
if (result != null) {
if (result.getContents() != null) {
String code = result.getContents();
Toast.makeText(this, "code " + code, Toast.LENGTH_SHORT).show();
Logger.d(Logger._JN, "onActivityResult download link: :%s ", code);
}
}
}
}
完成。
哈哈哈，還有更細緻的自定義

== 注意==：要注意DecoratedBarcodeView這個view,它是可以添加自定義的掃描view的，這樣，我們就有了自定義二維碼掃描及提示語。
