package com.example.zbartest;
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.content.Intent;
import android.content.pm.PackageManager;
import android.text.TextUtils;
import android.view.View;
import android.widget.Toast;
import android.widget.TextView;
import com.dm.zbar.android.scanner.ZBarConstants;
import com.dm.zbar.android.scanner.ZBarScannerActivity;
import net.sourceforge.zbar.Symbol;
public class MainActivity extends Activity {
private static final int ZBAR_SCANNER_REQUEST = 0;
private static final int ZBAR_QR_SCANNER_REQUEST = 1;
private TextView formatTxt, contentTxt;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
formatTxt = (TextView)findViewById(R.id.scan_format);
contentTxt = (TextView)findViewById(R.id.scan_content);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
public void launchScanner(View v) {
if (isCameraAvailable()) {
Intent intent = new Intent(this, ZBarScannerActivity.class);
startActivityForResult(intent, ZBAR_SCANNER_REQUEST);
} else {
Toast.makeText(this, "Rear Facing Camera Unavailable", Toast.LENGTH_SHORT).show();

return pm.hasSystemFeature(PackageManager.FEATURE_CAMERA);
}
@Override

String scanContent = data.getStringExtra("SCAN_RESULT_FORMAT");
formatTxt.setText("FORMAT: " + scanFormat);
contentTxt.setText("CONTENT: " + scanContent);
} else if(resultCode == RESULT_CANCELED && data != null) {
String error = data.getStringExtra(ZBarConstants.ERROR_INFO);
if(!TextUtils.isEmpty(error)) {
Toast.makeText(this, error, Toast.LENGTH_SHORT).show();
}
}
break;
}
}
}
I have added the ZbarScannerActivity,CameraPreview,ZbarConstatnts java files in the src folder of my project and added the ZbarScannerlibrary files into the libs folder. I just copied the three ZbarScannerActivity,CameraPreview,ZbarConstatnts files from the sample and pasted into my project.
Kindly help
