在 Android Studio 中使用 ZXING 更改 QR 扫描仪方向

Question

我希望你能帮我解决这个问题。我使用 Zxing Embedded Library 来使用 QR 扫描仪，问题是它处于横向模式，我想将其更改为纵向。

我在我的 Graddle 的依赖项上有这个

compile 'com.journeyapps:zxing-android-embedded:2.0.1@aar'
compile 'com.journeyapps:zxing-android-integration:2.0.1@aar'
compile 'com.google.zxing:core:3.0.1'

我的 java class 中有这个，可以通过按钮激活扫描仪...

public void scanQR(View view){
    IntentIntegrator integrator = new IntentIntegrator(this);
    integrator.setDesiredBarcodeFormats(IntentIntegrator.QR_CODE_TYPES);
    integrator.setResultDisplayDuration(0);//Text..
    integrator.setPrompt(" Scan a QR Code");
    integrator.setScanningRectangle(450, 450);//size
    integrator.setCameraId(0);  // Use a specific camera of the device
    integrator.initiateScan();

}

感谢您的帮助！

我正在使用

compile 'com.journeyapps:zxing-android-embedded:3.1.0@aar'

这是不同的版本，所以我不知道这是否适合你，但这对我有用。

More about my setup, I only compile

'com.journeyapps:zxing-android-embedded:3.1.0@aar'

'com.google.zxing:core:3.0.1'

and I did not compile

'com.journeyapps:zxing-android-integration:2.0.1@aar'

首先，我从 CaptureActivity

创建了一个 activity 扩展

或单击此 link 查看 class https://gist.github.com/TheGratefulDev/21a557c9a96333ec037c

public class CaptureActivityPortrait extends CaptureActivity {
//Nothing in side.
}

其次，添加这个

integrator.setCaptureActivity(CaptureActivityPortait.class);

进入您的集成商代码。

这是我的样子：

CustomIntegrator integrator = new CustomIntegrator(activity);
            integrator.setDesiredBarcodeFormats(CustomIntegrator.PDF_417);
            integrator.setPrompt("Scan a barcode");
            integrator.setCameraId(0);  // Use a specific camera of the device
            integrator.setOrientationLocked(true);
            integrator.setBeepEnabled(true);
            integrator.setCaptureActivity(CaptureActivityPortrait.class);
            integrator.initiateScan();

最后，在 AndroidMaifest 添加

   <activity
        android:name=".custom.CaptureActivityPortrait"
        android:screenOrientation="portrait" <---this is the most important line
        android:stateNotNeeded="true"
        android:theme="@style/zxing_CaptureTheme"
        android:windowSoftInputMode="stateAlwaysHidden">
    </activity>

我刚刚找到了最简单的方法。我们应该创建另一个 CaptureActivity.java class 并将此代码写入 onclick listener:

IntentIntegrator integrator = new IntentIntegrator(activity);
integrator.setPrompt("Scan a barcode");
integrator.setDesiredBarcodeFormats(integrator.ALL_CODE_TYPES);
integrator.setCameraId(0);  
integrator.setOrientationLocked(false);

// Replace with your own java class location here
integrator.setCaptureActivity(com.share.ants.hotelmenu.CaptureActivity.class);
integrator.setBeepEnabled(true);

Answer 3

对我有用：

IntentIntegrator integrator = new IntentIntegrator(YourActivity.this);
integrator.setDesiredBarcodeFormats(IntentIntegrator.ALL_CODE_TYPES);
integrator.setPrompt(getResources().getString(R.string.scan_a_barcode));
integrator.setCameraId(0);
// Use a specific camera of the device
integrator.setBeepEnabled(true);
integrator.setBarcodeImageEnabled(false);
integrator.initiateScan();

Answer 4

无需扩展 class，只需将其添加到清单中即可：

  <activity
            android:name="com.journeyapps.barcodescanner.CaptureActivity"
            android:screenOrientation="portrait"
            tools:replace="android:screenOrientation"
            android:stateNotNeeded="true"/>
