zxing 自动放大,扫描时自动更改屏幕方向（使用ZXING库）

I've MainActivity.kt where I show different fragments for different needs. At some point, I press button 'X' that calls startScanner() function:

private fun startScanner() {

IntentIntegrator(this)

.setOrientationLocked(false)

.setPrompt("SCANNING?")

.initiateScan()

}

Manifest.xml:

android:name=".MainActiity"

android:theme="@style/AppTheme"

tools:replace="android:screenOrientation"

android:stateNotNeeded="true"

android:screenOrientation="fullSensor"

android:windowSoftInputMode="stateHidden" />

Gradle.file:

compile 'com.journeyapps:zxing-android-embedded:3.6.0'

It does open scanner and everything, but in landscape mode.

Why is this not working?

解决方案

There is a shortcut to do this. Just add this to the manifest:

android:name="com.journeyapps.barcodescanner.CaptureActivity"

android:screenOrientation="portrait"

tools:replace="android:screenOrientation"

android:stateNotNeeded="true"/>
