I have the following code, It's a barcode scanning App using the ZXing Library.
txtoperatrice.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
IntentIntegrator integrator = new IntentIntegrator(activity);
integrator.setDesiredBarcodeFormats(IntentIntegrator.ALL_CODE_TYPES);
integrator.setPrompt("Scannez le code à barres SVP");
integrator.setCameraId(0);
integrator.setBeepEnabled(true);
integrator.setBarcodeImageEnabled(false);
integrator.initiateScan();
}
});
}
txtoperatrice
is the EditText where the the barcode result should be displayed. The result is got by the following code :
@Override
protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
IntentResult result = IntentIntegrator.parseActivityResult(requestCode, resultCode, data);
if (result!=null){
if(result.getContents()==null){
Toast.makeText(this, "Erreur de Scan", Toast.LENGTH_LONG).show();
}
else{
///////// DISPLAY THE CODE IN THE EDITTEXT txtoperatrice
}
}
else{
super.onActivityResult(requestCode, resultCode, data);
}
}
make txtoperatrice
a global variable and then assign it via findViewById
on your onCreate
Method
and onActivityResult set its text to the result using the following code
@Override
protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
IntentResult result = IntentIntegrator.parseActivityResult(requestCode, resultCode, data);
if (result!=null){
if(result.getContents()==null){
Toast.makeText(this, "Erreur de Scan", Toast.LENGTH_LONG).show();
}
else{
txtoperatrice.setText(result.getContents());
}
}
else{
super.onActivityResult(requestCode, resultCode, data);
}
}
If the object of EditText txtoperatrice is global in your class and give the id of XML component using findViewById(R.id.yourEditText) in onCreate function in the activity.
@Override
protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
IntentResult result = IntentIntegrator.parseActivityResult(requestCode, resultCode, data);
if (result!=null){
if(result.getContents()==null){
Toast.makeText(this, "Erreur de Scan", Toast.LENGTH_LONG).show();
}
else{
//you should have a string to put in this argument
//get your result in a string for example resultStr
String resultStr = result.getContents().tostring();
//the above line is just to clear what to do. it may not work exacly
// and then...
txtoperatrice.setText(resultStr);
}
}
else{
super.onActivityResult(requestCode, resultCode, data);
}
}
