QR scanner android ,displaying Scanned Value In textbox

Question

I am developing an application that involves QR scanning.I am able to get scanner application working by using Zxing library, which is launched from my application A. I need to store the information of the scanned product in textbox or editbox and later use it for some other purpose .

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    Intent intent = new Intent(MainActivity.this,  
            CaptureActivity.class);  
    // Intent intent = new  
    // Intent("com.google.zxing.client.android.SCAN");  
    intent.putExtra("SCAN_MODE", "QR_CODE_MODE");  
    startActivityForResult(intent, 0);  
}


@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 onActivityResult(int requestCode, int resultCode, Intent intent) {  
      if (requestCode == 0) {  
       if (resultCode == 1) {  
        // Handle successful scan  
        String capturedQrValue = intent.getStringExtra("RESULT");  
        // String format =  
        intent.getStringExtra("SCAN_RESULT_FORMAT");  

        Toast.makeText(MainActivity.this,"Scan Result:" + capturedQrValue, Toast.LENGTH_SHORT).show();  
        finish();     
         Intent it=new Intent(MainActivity.this,ThirdActivity.class);
         it.putExtra("Code", capturedQrValue);
         startActivity(it);

Please help me on the same.

Where exactly do you stuck (getting the value from intent or setting it to the textfield)? Please show in short code what you have tried. — Simulant, Apr 23 '14 at 12:49
The Zxing library provides a callback when something get scanned. Simply use this. — shkschneider, Apr 23 '14 at 12:50

then initialize String capturedQrValue globally. and anyway you got the value inside of onActivityResult method. you write one method like this

  public static String getResponce(){
   return capturedQrValue;
  }

call this method from your other activity where you want to show it. hope this helps you

if you want to open your other Activity directly after the scanning you can use this solution:

In your current Activity, create a new Intent:

Intent i = new Intent(getApplicationContext(), NewActivity.class);
i.putExtra("new_variable_name","value");
startActivity(i);

Then in the new Activity, retrieve those values:

Bundle extras = getIntent().getExtras();
if (extras != null) {
    String value = extras.getString("new_variable_name");
    TextField text;//get your textfield by ID or create it in the activity
    text.setText(value);
}

Use this technique to pass variables from one Activity to the other. found here: https://stackoverflow.com/a/7325248/1515052

if you want to open the other Activity later on you maybe want to store the value in a shared preferences file.
