Im creating a simple app which is for example i got 10 table row with check box and user click on 3 box and press next, i wan to print out only the 3 row the use clicked and adding extra button/icon beside it. Is it possible? please help ! Thank you !
to pass data to another Activity you can use Intents and putting your data as extra :
here is a sample :
Intent intent = new Intent(this, SecondActivity.class);
intent.putExtra("data", "My data in second activity");
startActivity(intent);
and for retrieving data in SecondActivity :
String data = getIntent().getStringExtra("data");
Yes, use putExtra and pass an ArrayList of String:
Intent intent = new Intent(Recipes2.this, XMLParser.class);
intent.putStringArrayListExtra("myList", (ArrayList<String>) myList);
startActivity(intent);
Here is the answer:
Intent intent = new Intent(getBaseContext(), SignoutActivity.class);
intent.putExtra("EXTRA_SESSION_ID", sessionId);
startActivity(intent)

Hello, I am making a project where the record contains ID, Name, Status And I have save it as a PDF the data, and its gets a notification after getting saved,
No I wanted to know how can I make that clickable and direct to file.
Below is the code I tried, but not working
Intent notificationIntent = new Intent(Intent.ACTION_VIEW);
notificationIntent.addCategory(Intent. CATEGORY_APP_FILES) ;
notificationIntent.setDataAndType(Uri.parse(filePath), "application/pdf");
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
PendingIntent resultIntent = PendingIntent. getActivity (SheetActivity. this, 0 , notificationIntent , 0) ;
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder
(SheetActivity. this, default_notification_channel_id )
.setSmallIcon(R.drawable. mcclogo )
.setContentTitle("PDF saved")
.setContentText(filePath)
.setContentIntent(resultIntent) ;
My app takes data from 4 EditTexts, puts them in an ArrayList and with a press of a button (using Intents) passes the data to second activity which then prints that data in 4 TextViews and has a button that returns me to first activity for next input. Is there any way of keeping all of my input data so I can show everything I've inputted in a TextView or Toast message?
Let's assume your first Activity is A and second activity is B
so in the A activity's button press you can call the 2nd activity using following code.
Intent intent = new Intent(A.this, B.class);
String input1 = txt1.getText().toString();
String input2 = txt2.getText().toString();
intent.putExtra("key1", input1 );
intent.putExtra("key2", input2 );
startActivity(intent);
From the B activity you can access these values using following code
Intent intent = getIntent();
String input1 = intent.getStringExtra("key1");
String input2 = intent.getStringExtra("key2");
yes you can. you can pass your data to second activity like this.
Intent intent1= new Intent(first.this, second.class);
Bundle bundle1=new Bundle();
bundle1.putString("data", et1.getText().toString());
intent1.putExtras(bundle1);
startActivityForResult(intent1, 0);
or you can restore them in a temporary database.
My Android service creates a notification with a custom button. The action for the custom button should open the "Create contact" system screen, with the phone number prefilled. This is the code:
// create the base notification
Intent notificationIntent = new Intent(context, MyService.class);
PendingIntent pendingIntent = PendingIntent.getService(
context, 0, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);
NotificationCompat.Builder builder = new NotificationCompat.Builder(context)
.setSmallIcon(R.drawable.ic_launcher)
.setContentTitle(title)
.setContentText(text)
.setAutoCancel(false)
.setOngoing(true)
.setContentIntent(pendingIntent);
// add the action to save to contacts
Intent saveIntent = new Intent(ContactsContract.Intents.Insert.ACTION);
saveIntent.setType(ContactsContract.RawContacts.CONTENT_TYPE);
saveIntent.putExtra(ContactsContract.Intents.Insert.PHONE, text);
saveIntent.putExtra(ContactsContract.Intents.Insert.PHONE_TYPE,
ContactsContract.CommonDataKinds.Phone.TYPE_WORK);
PendingIntent pendingSaveIntent = PendingIntent.getActivity(context, 0, saveIntent, 0);
builder.addAction(0, "Save to Contacts", pendingSaveIntent);
// show the notification
context.getSystemService(Context.NOTIFICATION_SERVICE).notify(0, builder.build());
The code works well the first time (let's say that I pass "01234-1234567" to it). However, subsequent calls keep showing the same dialog shown the first time, with the same value in it. So even if I call this piece code again with a different number in input (the value of "text" for the "Intents.Insert.PHONE" extra value) I'll always get "01234-1234567".
I tried cancelling the Contacts screen, manually create a new contact, completely stopping the Contacts apps...no matter what, next time I tap on the notification's button I'll get the screen with the value I originally passed on the first attempt.
Do you have any explanation or see anything wrong in the code?
I solved it. Basically, the system caches intents, unless they differ for something more than just the extra params. In my code I was only changing the phone number, so it was always using the same (first) cached intent. The solution is to use a flag to cancel the currently cached intent and create a new one
PendingIntent pendingSaveIntent = PendingIntent.getActivity(
context, 0, saveIntent, PendingIntent.FLAG_CANCEL_CURRENT);
The system cashes intents, so in your PendingIntent instead of typing 0 as flag, use (PendingIntent.FLAG_UPDATE_CURRENT), try this:
PendingIntent.getActivity(context, 0, saveIntent, PendingIntent.FLAG_UPDATE_CURRENT);

I`m trying to select images from gallery, but i only found the way to select a single image.
Intent photoPickerIntent = new Intent(Intent.ACTION_PICK);
photoPickerIntent.setType("image/*");
startActivityForResult(photoPickerIntent, 1);
Is there a way to select multiple images?
Create a custom gallery same like: Android custom image gallery with checkbox in grid to select multiple
First of all you need to use putExtra with your photoPickerIntent
photoPickerIntent.putExtra(Intent.EXTRA_ALLOW_MULTIPLE);
Then in your on activity result you should get ClipData from Intent like this
ClipData clipData = data.getClipData();
//Where data is param intent of onActivityForResult
And iterate this clipData to get URI for specific picked image.
for (int i = 0; i < clipData.getItemCount(); i++){
Uri uri = clipData.getItemAt(i).getUri();
}
I hope this helps
Why don't you try ACTION_SEND_MULTIPLE thing. You will receive a set of Uris.
Something like
if (Intent.ACTION_SEND_MULTIPLE.equals(action))
&& Intent.hasExtra(Intent.EXTRA_STREAM)) {
ArrayList<Parcelable> list =
intent.getParcelableArrayListExtra(Intent.EXTRA_STREAM);
for (Parcelable parcel : list) {
Uri uri = (Uri) parcel;
/// do things here.
}
}
Saw this code block on a google-groups post. Just try this out.
Thanks.
I think, you should implement custom gallery for multiple image pick action.

How to display the text of a textfield in a url section in android?
Here is the code
final Text q = (Text) findViewById(R.id.q);
Intent i = new Intent("android.intent.action.VIEW", Uri.parse("http://www.google.com/search?q="));
startActivity(i);
i want to use as query this (Text) findViewById(R.id.q); . How??
What you are looking for is actually this.
final EditText q = (EditText) findViewById(R.id.q);
Intent i = new Intent("android.intent.action.VIEW",
Uri.parse("http://www.google.com/search?q=" + q.getText().toString()));
startActivity(i);
Note the use of EditText. Text is not the correct class you were looking for.
Intent i = new Intent("android.intent.action.VIEW", Uri.parse("http://www.google.com/search?q=" + q.getText()));
