am scan Qr code/Barcode, so I want to scan different qr code/barcode and arrange them is String listview.
Example I want to setText() like this ,scanNumber1,scanNumber2,....,..., so far i have managed to scan that Qr Code/Barcode but when i scan the next number it remove the first one, so I want ti arrange those number.
here is my code
public void scanCode(View view){
IntentIntegrator intentIntegrator = new IntentIntegrator(this);
intentIntegrator.initiateScan();
}
#Override
protected void onActivityResult(int requestCode, int resultCode, #Nullable Intent data) {
IntentResult intentResult = IntentIntegrator.parseActivityResult(requestCode, resultCode, data);
String scanNumber=intentResult.getContents();
if (intentResult != null) {
if(intentResult.getContents() == null) {
Toast toast = Toast.makeText(getApplicationContext(), "Scan The QR code/Barcode", Toast.LENGTH_LONG);
toast.show();
}
//validate ur scan numbers
else if (intentResult.getContents().length() == 10) {
textView1.setText(intentResult.getContents());
}
else if(intentResult.getContents().length() == 12){
textView2.setText(intentResult.getContents());
}
else {
Toast toast = Toast.makeText(getApplicationContext(), "That Number is Out Of Our Range", Toast.LENGTH_LONG);
toast.show();
}
}
super.onActivityResult(requestCode, resultCode, data);
}
and this is output
so I want on that Slave to appear like ,scanNumber1,scanNumber2,....,...,
you can use a global JointoString function object to achieve the desired behaviour i.e. "barcode1","barcode2"....
ArrayList<String> results = new ArrayList<String>()
when you receive the result try
results.add(<value>)
while displaying to text view use
textView.setText(results.joinToString(","))

I am trying to get result for dialer Intent using startActivityForResult()
Below is my code for Dialer Intent.
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(Intent.ACTION_DIAL);
intent.setData(Uri.parse("tel:123456789"));
startActivityForResult(intent, 1234);
}
});
#Override
protected void onActivityResult(int requestCode, int resultCode, #Nullable Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(requestCode == 1234){
if (resultCode == Activity.RESULT_OK){
Toast.makeText(getApplicationContext(), "result ok", Toast.LENGTH_LONG).show();
}else if (resultCode == Activity.RESULT_CANCELED){
Toast.makeText(getApplicationContext(), "Result Cancelled", Toast.LENGTH_LONG).show();
}
}
}
whenever I am returning to my activity, Result Cancelled Toast is triggering.
Thanks in advance.
From doc:
ACTION_DIAL
public static final String ACTION_DIAL
You only have the ACTION. If you want to call a number from your application then you just have to put these lines of code into the onClick() method and can get what you want:
Intent intent = new Intent(Intent.ACTION_DIAL);
intent.setData(Uri.parse("tel:123456789"));
startActivity(intent); // no need to use startActivityResult(intent,1234)
Here, If an ACTION_DIAL input is nothing, an empty dialer is started; else getData() is URI of a phone number to be dialed or a tel: <yourURI> of an explicit phone number.
Additionally, there is no "Output" of RESULT_OK or RESULT_CANCELED, Cause, the startActivityResult() doesn't mean anything to ACTION_DIAL but startActivity(intent). Hope it helps.
why am I getting RESULT_CANCELED instead of RESULT_OK.
ACTION_DIAL does not return a result. If you read the documentation for ACTION_DIAL, you will see "Output: nothing". Hence, you will usually get RESULT_CANCELED. Only activities designed for use with startActivityForResult() will return a result code.
I have a Android Device with a embedded barcode Scanner.
On pressing the "Scan" button on device, it scans the barcode and the data is displayed in the EditText only if the cursor is on EditText. i.e. The EditText is selected.
I wish to get the scanned result without the EditText selected.
I have tried it with onActivityResult
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
}
But I am not getting any results on this.
What can I do ?
I don't want to press a Button to activate the Scanner.
Using the ZXIng library, you can launch the scanner as an intent and parse the result.
import com.google.zxing.integration.android.IntentIntegrator;
import com.google.zxing.integration.android.IntentResult;
public void onActivityResult(int requestCode, int resultCode, Intent intent){
IntentResult scanResult = IntentIntegrator.parseActivityResult(requestCode, resultCode, intent);
Context context = getApplicationContext();
if (scanResult != null){
String scanContent = scanResult.getContents();
Toast toast = Toast.makeText(context, scanContent, 5000);
toast.show();
}
else {
Toast toast = Toast.makeText(context, "Error", 5000);
toast.show();
}
};
This intent launched through one of the android lifecycle methods, such as the onCreate() override.
IntentIntegrator scanIntegrator = new IntentIntegrator(this);
scanIntegrator.initiateScan();
I am making an android studio app and I want it to make a TextView disappear when I say a certain phrase. The code saves everything I say into an array list. I want to see if it includes the phrase.
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode){
case 100:
if (resultCode == RESULT_OK && data != null){
ArrayList<String> result = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
boolean yes = Arrays.asList(result.get(0)).contains(InputActivity.Item1);
if(yes == true){
result1.setVisibility(View.GONE);
}
}
break;
}
}
Use
for(String s:result){
if(s.equals(InputActivity.Item1)){
//hide text view
}
}
I have a MultiplePhotoSelectActivity.java which let user select multiple photo and store the path in an ArrayList.
public void btnChoosePhotosClick(View v){
ArrayList<String> selectedItems = imageAdapter.getCheckedItems();
if (selectedItems!= null && selectedItems.size() > 0) {
//Toast.makeText(MultiPhotoSelectActivity.this, "Total photos selected: " + selectedItems.size(), Toast.LENGTH_SHORT).show();
Log.d(MultiPhotoSelectActivity.class.getSimpleName(), "Selected Items: " + selectedItems.toString());
Intent intent = new Intent(MultiPhotoSelectActivity.this,PreuploadActivity.class);
intent.putStringArrayListExtra("selectedItems", selectedItems);
setResult(RESULT_OK, intent);
startActivity(intent);
}
}
This is ArrayList<String> selectedItems come from imageAdapter
ArrayList<String> getCheckedItems() {
ArrayList<String> mTempArry = new ArrayList<>();
for(int i=0;i<mImagesList.size();i++) {
if(mSparseBooleanArray.get(i)) {
mTempArry.add(mImagesList.get(i));
}
}
return mTempArry;
}
After user choose the photo,the following result will appear in logcat
D/MultiPhotoSelectActivity: Selected Items: [/storage/emulated/0/Pictures/Screenshot_1486795867.png, /storage/emulated/0/Pictures/15592639_1339693736081458_1539667284_n.jpg, /storage/emulated/0/15592639_1339693736081458_1539667284_n.jpg]
The problem now is,I want to display the image in my another activity using the file path in the array list,after the user choose the image
Here is PreuploadActivity.java that should be receive the intent data.
This is the button to let user choose photo in MultiplePhotoSelectActivity.java
//this button will open gallery,and select photo
addPhoto.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(PreuploadActivity.this,MultiPhotoSelectActivity.class);
startActivityForResult(intent,PICK_IMAGE_REQUEST);
}
});
This is the onActivityResult() which should receive the Intent data from MultiplePhotoSelectActivity.java
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if(requestCode == PICK_IMAGE_REQUEST && resultCode == RESULT_OK && data.getData() !=null){
ArrayList<String> selectedItems = data.getStringArrayListExtra("selectedItems");
for(String selectedItem : selectedItems){
Uri filePath = Uri.parse(selectedItem);
try{
// bimatp factory
BitmapFactory.Options options = new BitmapFactory.Options();
options.inSampleSize = 8;
bitmap = BitmapFactory.decodeFile(filePath.getPath(),
options);
//Setting image to ImageView
ImageView imageView = new ImageView(getApplicationContext());
LinearLayout.LayoutParams layoutParams =
new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,
ViewGroup.LayoutParams.MATCH_PARENT);
imageView.setLayoutParams(layoutParams);
imageView.setScaleType(ImageView.ScaleType.FIT_CENTER);
imageView.setPadding(0, 0, 0, 10);
imageView.setAdjustViewBounds(true);
imageView.setImageBitmap(bitmap);
linearMain.addView(imageView);
}catch (Exception e) {
e.printStackTrace();
}
}
So now in onActivityResult() of PreuploadActivity.java I cant display back the image in the ArrayList which sent from MultiplePhotoSelectActivity.java.I suspect is something wrong when putExtra in the intent,what I tried so far but still no different.
The answer of this Stackoverflow question
putParcelable or putSerializable like the answer
How to transfer a Uri image from one activity to another?
So what I need to know,
1) How should I putExtra and getExtra in the intent in both Activity in order send and receive the ArrayList of the image?
2) Is my handle to display the image correct?If no,please tell me what I doing wrong.
EDIT:Try for Aslam Hossin solution
After I tried this
ArrayList<String> myList = (ArrayList<String>) getIntent().getSerializableExtra("selectedItems ");
I got the following error
After looking at some documentation I figure out I make a few mistake
MultiPhotoSelectActivity.java
Intent intent = new Intent(MultiPhotoSelectActivity.this,PreuploadActivity.class);
intent.putStringArrayListExtra("selectedItems", selectedItems);
setResult(RESULT_OK, intent);
startActivity(intent);
I figure out,there are 3 mistake at above code,
1)In MultiPhotoSelectActivity.java should not a new intent,but it should be send the data back to PreuploadActivity.java
2) I should setResult like this
setResult(Activity.RESULT_OK, data);
3) According to the documentation as below ,so I add finish() after setResult()
Data is only returned once you call finish(). You need to call setResult() before calling finish(), otherwise, no result will be returned.
I solve it by setting result code in PreuploadActivity.java like below
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(requestCode == PICK_IMAGE_REQUEST && resultCode == Activity.RESULT_OK ){
//setting Activity.RESULT_OK
ArrayList<String> selectedItems = data.getStringArrayListExtra("selectedItems");
This is MultiPhotoSelectActivity.java I do the following changes
ArrayList<String> selectedItems = imageAdapter.getCheckedItems();
if (selectedItems!= null && selectedItems.size() > 0) {
//Toast.makeText(MultiPhotoSelectActivity.this, "Total photos selected: " + selectedItems.size(), Toast.LENGTH_SHORT).show();
Log.d(MultiPhotoSelectActivity.class.getSimpleName(), "Selected Items: " + selectedItems.toString());
final Intent data = new Intent();
data.putStringArrayListExtra("selectedItems", selectedItems);
setResult(Activity.RESULT_OK, data);
finish();
}
}
I am having some issues with ZXing's barcode scanner in my android application. I asked a question here yesterday that explains a null pointer error that I was having. The issue was solved and just showed that the cursor wasnt retrieving any information back.
My issues is that I know query is correct and I know the code is correct because I have tested it out without the scanner separately and it all works fine. Is it possible that I am calling to the database wrong in the barcode scanner intent or is there a certain way that I should be doing it?
Any help or guidance would be great!
onActivity Result
public void onActivityResult(int requestCode, int resultCode, Intent intent) {
if (requestCode == 0) {
if (resultCode == RESULT_OK) {
//get the extras that are returned from the intent
barcode_number = intent.getStringExtra("SCAN_RESULT");
String bNumber = barcode_number.toString();
//Code to add scanned item to DB, needs barcode data before can be ruin
final Cursor barInformation = adapter.barcodeInfo(barcode_number);
barInformation.moveToFirst();
String itemName = barInformation.getString(barInformation.getColumnIndex("barcode_item_name"));
Toast toast = Toast.makeText(this, "Barcode Number:" + itemName ,Toast.LENGTH_SHORT);
toast.show();
}
}
}
Query
public Cursor barcodeInfo(String number){
// Safe check to make sure db and number is not null
if(db == null || number == null){
return null;
}
return db.rawQuery("select _id, barcode_item_name, barcode_measurement, barcode_unit from barcode where barcode_number = ?", new String[]{number});
}
Error
Caused by: java.lang.NullPointerException: Attempt to invoke virtual method 'android.database.Cursor android.database.sqlite.SQLiteDatabase.rawQuery(java.lang.String, java.lang.String[])' on a null object reference

Try like this
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
switch (requestCode) {
case IntentIntegrator.REQUEST_CODE: {
if (resultCode != RESULT_CANCELED) {
IntentResult scanResult = IntentIntegrator.parseActivityResult(requestCode, resultCode, data);
String strData = scanResult.getContents(); // use this
} else {
Toast.makeText(this, "Error message", Toast.LENGTH_LONG).show();
}
break;
}
}
}
I have fixed the issue. My problem was that I wasnt opening the database before I was calling the functions and thus the function was a null object. The correct code is as below.
adapter.open(); // I was missing this line
Cursor c = adapter.barcodeInfo(bNumber);
c.moveToPosition(-1);
while(c.moveToNext())
{
name = c.getString(c.getColumnIndex("barcode_item_name"));
measurement = c.getInt(c.getColumnIndex("barcode_measurement"));
unit = c.getString(c.getColumnIndex("barcode_unit"));
Toast toast = Toast.makeText(this, "Adding" + name + "to Kitchen", Toast.LENGTH_SHORT);
toast.show();
}
