android中使用zxing扫描二维码以及条形码

步骤一：

在gradle集成Zxing。

加入以下代码

compile 'com.journeyapps:zxing-android-embedded:3.0.2@aar'
compile 'com.google.zxing:core:3.2.0'

步骤二：

生成控件调用

步骤三：设置照相机权限：

步骤四：加入实例来获取扫描结果：

@Overrideprotected void onActivityResult(int requestCode, int resultCode, Intent data) {    IntentResult result = IntentIntegrator.parseActivityResult(requestCode, resultCode, data);    if(result != null) {        if(result.getContents() == null) {            Toast.makeText(this, "扫码取消！", Toast.LENGTH_LONG).show();        } else {            Toast.makeText(this, "扫描成功，条码值: " + result.getContents(), Toast.LENGTH_LONG).show();        }    } else {        // This is important, otherwise the result will not be passed to the fragment        super.onActivityResult(requestCode, resultCode, data);    }}

步骤五：控件调用

public void onScanBarcode(View v){    IntentIntegrator integrator = new IntentIntegrator(this);    integrator.setDesiredBarcodeFormats(IntentIntegrator.ONE_D_CODE_TYPES);    integrator.setPrompt("扫描条形码");    integrator.setCameraId(0);    integrator.setBeepEnabled(false);    integrator.initiateScan();}public void onScanQrcode(View v){    IntentIntegrator integrator = new IntentIntegrator(this);    integrator.setDesiredBarcodeFormats(IntentIntegrator.QR_CODE_TYPES);    integrator.setPrompt("扫描二维码");    integrator.setCameraId(0);    integrator.setBeepEnabled(false);    integrator.initiateScan();}

声明：

IntentIntegrator integrator = new IntentIntegrator(this);
// 设置要扫描的条码类型，ONE_D_CODE_TYPES：一维码，QR_CODE_TYPES-二维码
        integrator.setDesiredBarcodeFormats(IntentIntegrator.ONE_D_CODE_TYPES);
        integrator.setPrompt("扫描条形码");
        integrator.setCameraId(0); // 使用默认的相机
        integrator.setBeepEnabled(false); // 扫到码后播放提示音
        integrator.initiateScan();
