I used zxing to build into my application. You will need a bit of coding. First include core.jar , its at core/core.jar,in your build path, then go to their client ,its at android/..../com.google.zxing, and get their code(This is not recommended by the devs, because your copy and pasting.) last, Add this code:
package com.wtsang02.activities;
import android.app.Activity;
import android.content.Intent;
import android.graphics.Bitmap;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.ImageView;
import android.widget.TextView;
import android.widget.Toast;
import com.google.zxing.BarcodeFormat;
import com.google.zxing.BinaryBitmap;
import com.google.zxing.ChecksumException;
import com.google.zxing.FormatException;
import com.google.zxing.LuminanceSource;
import com.google.zxing.MultiFormatReader;
import com.google.zxing.NotFoundException;
import com.google.zxing.Reader;
import com.google.zxing.Result;
import com.google.zxing.ResultPoint;
import com.google.zxing.common.HybridBinarizer;
public class QRDecoder extends Activity implements OnClickListener {
private String text;
private Button webbutton;
private Bitmap bmp;
private ImageView ivPicture;
private TextView textv;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.mysales);
webbutton = (Button)findViewById(R.id.webbutton);
ivPicture = (ImageView) findViewById(R.id.ivPicture);
textv= (TextView) findViewById(R.id.mytext);
webbutton.setOnClickListener(this);
}
private void decode() {
if (bmp == null) {
Log.i("tag", "wtf");
}
bmp = bmp.copy(Bitmap.Config.ARGB_8888, true);
int[] intArray = new int[bmp.getWidth() * bmp.getHeight()];
bmp.getPixels(intArray, 0, bmp.getWidth(), 0, 0, bmp.getWidth(),
bmp.getHeight());
LuminanceSource source = new com.google.zxing.RGBLuminanceSource(
bmp.getWidth(), bmp.getHeight(), intArray);
BinaryBitmap bitmap = new BinaryBitmap(new HybridBinarizer(source));
Reader reader = new MultiFormatReader();
try {
Result result = reader.decode(bitmap);
text = result.getText();
byte[] rawBytes = result.getRawBytes();
BarcodeFormat format = result.getBarcodeFormat();
ResultPoint[] points = result.getResultPoints();
textv.setText(text);
} catch (NotFoundException e) {
e.printStackTrace();
} catch (ChecksumException e) {
e.printStackTrace();
} catch (FormatException e) {
e.printStackTrace();
}
Log.i("done", "done");
if(text!=null)
Toast.makeText(getBaseContext(), text, Toast.LENGTH_LONG).show();
else{
Toast.makeText(getBaseContext(), "QQ", Toast.LENGTH_LONG).show();
}
}
@Override
public void onClick(View v) {
Intent i = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(i, 0);
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK) {
Bundle extras = data.getExtras();
bmp = (Bitmap) extras.get("data");
ivPicture.setImageBitmap(bmp);
decode();
}
}
}
This code will use your phone's default camera, if you need to use their client, you will need to start their CaptureActivity, Your layout should include a TextView to show results, ImageView to show the image you captured, and Button to start the camera. . This is based off of 2.1zxing.
