在Android Studio中使用ZXING更改QR扫描仪方向 [英] Change QR Scanner orientation with ZXING in Android Studio

问题描述

希望您能对此有所帮助.我使用Zxing嵌入式库以使用QR扫描仪，问题是在横向模式下，我想将其更改为纵向.

I hope you can help me with this. Im using the Zxing Embedded Library in order to use the QR scanner, the problem is that is on Landscape mode and I would like to change it to Portrait.

我有这个关于我的Graddle的依赖项

I have this on the dependencies of my Graddle

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'

并且我在Java类中有一个按钮来激活扫描器...

and I have this in my java class to activate the scanner with a button...

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！

推荐答案

我正在使用

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

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

它是不同的版本，所以我不知道这是否对您有用， 但这对我有用.

It is different version, so I don't know if this will work for you, but this is working for me.

有关我的设置的更多信息，我只能编译

More about my setup, I only compile

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

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

'com.google.zxing:core:3.0.1'

'com.google.zxing:core:3.0.1'

我没有编译

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

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

首先，我创建了一个来自CaptureActivity的活动

First I created an activity extend from the CaptureActivity

或单击此链接以查看类 https://gist.github.com/TheGratefulDev/21a557c9a96333ec037c

or click this link to view the class https://gist.github.com/TheGratefulDev/21a557c9a96333ec037c

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

第二，添加此

integrator.setCaptureActivity(CaptureActivityPortait.class);

integrator.setCaptureActivity(CaptureActivityPortait.class);

进入您的集成商代码.

into your integrator code.

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中添加

Finally, at the AndroidMaifest add

   <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>
