在Android Studio中使用ZXING更改QR扫描仪方向

Question

我希望你能帮助我.我使用Zxing嵌入式库来使用QR扫描仪,问题是在横向模式下,我想将其更改为纵向.

我在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'

我在我的java类中有这个用按钮激活扫描仪...

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();

}

谢谢您的帮助!

Answer 1

不要扩展类,只需将其添加到清单:

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

奇迹般有效

Answer 2

我在用

编译'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.

更多关于我的设置,我只编译

'com.journeyapps:斑马线,Android的嵌入式:3.1.0@aar'

'com.google.zxing:核心:3.0.1'

我没有编译

'com.journeyapps:斑马线,Android的整合:2.0.1@aar'

首先,我从CaptureActivity创建了一个活动扩展

或单击此链接查看课程https://gist.github.com/TheGratefulDev/21a557c9a96333ec037c

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

其次,加上这个

integrator.setCaptureActivity(CaptureActivityPortait.class);

进入您的集成商代码.

这就是我的样子:

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>
