on onActivityResult you need to call
IntentResult scanningResult = IntentIntegrator.parseActivityResult(requestCode, resultCode, intent);
Sample usage
@Override
public void onActivityResult(int requestCode, int resultCode, Intent intent) {
IntentResult result = IntentIntegrator.parseActivityResult(requestCode, resultCode, intent);
if (result != null) {
String contents = result.getContents();
if (contents != null) {
Log.d(TAG, "Success");
// result.toString() holds the result info
} else {
Log.d(TAG, "Failed");
}
}
}
Update On scan button click do the following
Button scanner = (Button) findViewById(R.id.scanner);
scanner.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
IntentIntegrator integrator = new IntentIntegrator(MainActivity.this);
integrator.addExtra("SCAN_WIDTH", 800);
integrator.addExtra("SCAN_HEIGHT", 200);
integrator.addExtra("RESULT_DISPLAY_DURATION_MS", 3000L);
integrator.addExtra("PROMPT_MESSAGE", "Custom prompt to scan a product");
integrator.initiateScan(IntentIntegrator.PRODUCT_CODE_TYPES);
}
});
For QR-CODE scan do this
IntentIntegrator integrator = new IntentIntegrator(MainActivity.this);
integrator.initiateScan(IntentIntegrator.QR_CODE_TYPES);
Follow the test for more info.
