}An activity which this library provides is info.vividcode.android.zxing.CaptureActivity.
To use it, you need to declares it.
(You can also define subclass of CaptureActivity and use it, if you want.)
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="org.example.your.app.pkg">
<application>
<activity android:name="info.vividcode.android.zxing.CaptureActivity"
android:theme="@style/Theme.ZXingCaptureActivity"
android:screenOrientation="landscape"/>To start CaptureActivity activity and receive result of barcode scanning, call
startActivityForResult method as below.
// Create intent.
Intent captureIntent = new Intent(this, CaptureActivity.class);
// Using `CaptureActivityIntents`, set parameters to an intent.
// (There is no requisite parameter to set to an intent.)
// For instance, `setPromptMessage` method set prompt message displayed on `CaptureActivity`.
CaptureActivityIntents.setPromptMessage(captureIntent, "Barcode scanning...");
// Start activity.
startActivityForResult(captureIntent, 1);After reading barcode, you receive the result through onActivityResult callback method.
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data){
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == 1) {
if(resultCode == RESULT_OK) {
CaptureResult res = CaptureResult.parseResultIntent(data);
Toast.makeText(this, res.getContents() + " (" + res.getFormatName() + ")", Toast.LENGTH_LONG).show();
} else {
// Process comes here when “back” button was clicked for instance.
}
