android中使用zxing扫描二维码以及条形码

步骤一：

gradleZxing

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

<Button     android:id="@+id/button2"     android:layout_width="wrap_content"     android:layout_height="wrap_content"     android:layout_alignEnd="@+id/button"     android:layout_alignRight="@+id/button"     android:layout_below="@+id/button"     android:layout_marginBottom="8dp"     android:layout_marginEnd="8dp"     android:layout_marginStart="8dp"     android:layout_marginTop="8dp"     android:onClick="onScanBarcode"     android:text="条形码"     app:layout_constraintBottom_toBottomOf="parent"     app:layout_constraintEnd_toEndOf="parent"     app:layout_constraintStart_toStartOf="parent"     app:layout_constraintTop_toTopOf="parent"     app:layout_constraintVertical_bias="0.232" />  <Button     android:id="@+id/button"     android:layout_width="wrap_content"     android:layout_height="wrap_content"     android:layout_alignParentTop="true"     android:layout_centerHorizontal="true"     android:layout_marginBottom="8dp"     android:layout_marginStart="8dp"     android:onClick="onScanQrcode"     android:text="二维码"     app:layout_constraintBottom_toBottomOf="parent"     app:layout_constraintEnd_toEndOf="@+id/button2"     app:layout_constraintHorizontal_bias="1.0"     app:layout_constraintStart_toStartOf="@+id/button2"     app:layout_constraintTop_toBottomOf="@+id/button2"     app:layout_constraintVertical_bias="0.176" />

步骤三：设置照相机权限：

<uses-permission android:name="android.permission.CAMERA"></uses-permission>

步骤四：加入实例来获取扫描结果：

@Override protected 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);
"扫描条形码");
0// 使用默认的相机
integrator.setBeepEnabled(false); // 扫到码后播放提示音
integrator.initiateScan();
